The given quadratic equation y=x^2+4x+5 has no real solutions because the discriminant is negative. Therefore, there are no zeros for this equation, making option A (There are no zeros) the correct choice.
Explanation:The question asks to identify any zeros of the quadratic equation [tex]y=x^2+4x+5.[/tex]To find the zeros, we need to set the equation equal to zero and solve for x. This is typically done using the quadratic formula, which is √x=(-b±√(b^2-4ac))/(2a), where a=1, b=4, and c=5 in our equation.
Substituting these values into the quadratic formula gives: x=(-4±√((4)^2-4*1*5))/(2*1) = (-4±√(16-20))/2 = (-4±√(-4))/2. Since the value under the square root sign (the discriminant) is negative, this equation has no real solutions. Thus, there are no zeros for the given quadratic equation, making option A the correct choice.

Antoine has a carnival booth at the school fair where students randomly select a ping pong ball from a can. He wants to place 5 red ping pong balls an n blue ping pong balls in the can. He also wants the probability of randomly choosing a blue ping pong ball to be 3/5.
Part A:
Write an equation that can be used to model this situation.
Part B:
Solve the equation and interpret the solution in terms of the context, determining if the solution is viable.
Answer:
(a)[tex]5n=3n+15[/tex]
(b)[tex]n=7.5[/tex]
Solution is not viable
Step-by-step explanation:
(a)
Total number of red ping pong balls[tex]=5[/tex]
Total number of red ping pong balls[tex]=n[/tex]
Now, probability of an event [tex]=\frac{Number of favourable events}{Total number of events}[/tex]
Then, theprobability of randomly choosing a blue ping pong ball is
[tex]=\frac{n}{n+5}[/tex]
Given that this probability is[tex]=\frac{3}{5}[/tex]
Thus, we have that,
[tex]\frac{n}{n+5}= \frac{3}{5}\\ 5n=3(n+5)\\5n=3n+15[/tex]
(b)
Solving, the above equation,
[tex]5n=3n+15\\2n=15\\n=7.5[/tex]
This solution is not viable as, number of ping pong ball must be an integer and not a decimal number.
How are the absolute values of opposite intergers related ?? Help me 16 points give me a good answer plz and THX
Opposite integers are pairs of opposite sign, so the opposite integer to 2 is -2, 3 is opposite to -3, and so on.
Absolute value make any integer non-negative by removing its negative sign if there is any.
Absolute values of opposite integers are related in that they are *identical*
Any pair of opposite integers shares the same absolute value.

Which statement best completes the sentence below? If the measure of /_4 is 70^o, then the measure of /_8 is _________________. A 110^o because /_4 and /_8 are supplementary angles. B 70^o because /_4 and /_8 are alternate exterior angles. C 110^o because /_4 and /_8 are corresponding angles. D 70^o because /_4 and /_8 are corresponding angles.
Answer:
As given, measure of angle 4 is 70°
Then what would be the measure of ∠8.
Following cases comes into consideration
1. If ∠4 and ∠8 are supplementary angles i.e lie on same side of Transversal, then
∠4 + ∠8=180°
⇒70°+∠8=180° [∠4=70°]
⇒∠8=180°-70°
⇒∠8=110°
2nd possibility
But if these two angles i.e ∠4 and ∠8 forms a linear pair.Then
⇒ ∠4 + ∠8=180°
⇒70°+∠8=180° [∠4=70°]
⇒∠8=180°-70°
⇒∠8=110°
3rd possibility
If ∠4 and ∠8 are alternate exterior angles.
then, ∠4 = ∠8=70°
4th possibility
If If ∠4 and ∠8 are corresponding angles.
then, ∠4 = ∠8=70°
Out of four options given Option A[ 110° because ∠4 and ∠8 are supplementary angles], Option B[70° because ∠4 and ∠8 are alternate exterior angles.] and Option D[70° because ∠4 and ∠8 are corresponding angles.] are Correct.
Jeremy surveyed students in his class about their spending habits in the school cafeteria. He used the data to create a scatterplot.
Answer:
Step-by-step explanation:
From the graph, you can first see that there is a positive slope, and a negative y intercept. That should automatically rule out the first option.next, find the slop...
To do this take the two points that are given (2,5.5) and (5,15.25) and do rise over run. This would be (15.25-5.5)/(5-2). I just put this in a calculator and found the slope to be 3.25. You automatically know the answer because the only equation with the slope 3.25 is the third one.
The scatterplot shows the distribution of the students' spending habit
The equation of the trend line is: [tex]\mathbf{y = 3.25x -1}[/tex]
From the scatter plot (see attachment), we have the following points:
[tex]\mathbf{(x,y) = (2,5.5)\ (5,15.25)}[/tex]
So, the slope (m) of the trend line is:
[tex]\mathbf{m = \frac{y_2 - y_1}{x_2 - x_1}}[/tex]
This gives
[tex]\mathbf{m = \frac{15.25 - 5.5}{5- 2}}[/tex]
[tex]\mathbf{m = \frac{9.75}{3}}[/tex]
[tex]\mathbf{m = 3.25}[/tex]
The equation of the trend line is then calculated as:
[tex]\mathbf{y = m(x - x_1) + y_1}[/tex]
This gives
[tex]\mathbf{y = 3.25(x - 2) + 5.5}[/tex]
[tex]\mathbf{y = 3.25x - 6.5 + 5.5}[/tex]
[tex]\mathbf{y = 3.25x -1}[/tex]
Hence, the equation of the trend line is: [tex]\mathbf{y = 3.25x -1}[/tex]

(w+14)/(4w+6)=(3)/(4) show work plz
Answer:
w = -1.44 and w = -14.06
Step-by-step explanation:
That "(3) / (4)" in (w+14)/(4w+6)=(3)/(4) looks fishy. Assuming that you really meant 3/4, then we have (w+14)/(4w+6)=3/4.
Mult. both sides by 4 to remove the fraction: 4(w+14)/(4w+6) = 3.
Multiply out (w+14)/(4w+6): 4w^2 + 6w + 56w + 84. Combine the w terms, obtaining 4w^2 + 62w + 84. Then the original equation becomes:
4w^2 + 62w + 84 = 3, or 4w^2 + 62w + 81 = 0.
This is a quadratic equation, with a = 4, b = 62 and c = 81. The two roots (values of
w) are as follows:
-62 plus or minus √(62^2-4(4)(81)
----------------------------------------------------------
8
-62 plus or minus √(2548) -62 plus or minus 50.48
w = ------------------------------------------- = ---------------------------------------
8 8
Simplifying, we get w = -1.44 and w = -14.06
To solve the algebraic equation (w+14)/(4w+6) = 3/4, we clear the fractions, combine like terms, and isolate the variable w, which gives us the solution w = 4.75.
To solve the equation (w+14)/(4w+6) = 3/4, we first clear the fractions by multiplying both sides by the least common denominator, which is 4(4w+6). This eliminates the denominators and gives us:
4(w + 14) = 3(4w + 6)
Distribute the 4 on the left side and the 3 on the right side:
4w + 56 = 12w + 18
Next, we want to get all the terms with w on one side and the constant terms on the other. Subtract 4w and 18 from both sides:
4w + 56 - 4w - 18 = 12w + 18 - 4w - 18
This simplifies to:
38 = 8w
Divide both sides by 8 to isolate w:
w = 38 / 8
Finally, simplify the fraction to find the value of w:
w = 4.75

Audrey is trying to find the equation of a line parallel to y = 2 over 3 x −5 in slope-intercept form that passes through the point (−6, −1). Which of the following equations will she use
Final answer:
To find the parallel line's equation, Audrey used the slope of 2/3 from the given line and the point (-6, -1) to write the equation in point-slope form, eventually simplifying it to y = 2/3x + 3.
Explanation:
Audrey is looking to find the equation of a line that is parallel to the line with the equation y = 2/3x - 5 and that passes through the point (-6, -1). Since parallel lines have the same slope, our new line will keep the slope of 2/3. Using the point-slope form of the equation of a line, we set up y - y1 = m(x - x1). Plugging in the known slope m and point (x1, y1), we get y - (-1) = 2/3(x - (-6)). After simplifying, we have y + 1 = 2/3x + 4. Finally, we solve for y by subtracting 1 from both sides, yielding the equation y = 2/3x + 3 as the line that is parallel to the original line and passes through the given point.

10x + 5 = 8x + 2
10x + 5 = 8x + 2
Subtract 5 from both sides.
10x = 8x - 3
Subtract 8x from both sides.
2x = -3
Subtract both sides by 2.
x = -1.5
Because we are able to get a value for x, we know that the equation is true, as we can plug the value of x back into the original equation to verify.
10(-1.5) + 5 = 8(-1.5) + 2
-15 + 5 = -12 + 2
-10 = -10 √ this equation is true.
For the equation 10x + 5 = 8x + 2, the statement is true.
The given equation is 10x + 5 = 8x + 2.
The first thing to do is to subtract 5 from both sides.
10x + 5 - 5 = 8x + 2 - 5
10x = 8x - 3
Then, we'll subtract 8x and this will be:
10x - 8x = -3
2x = -3
Divide both side by 2
2x/2 = -3/2
x = -1.5
10x + 5 = 8x + 2,
10(-1.5) + 5 = 8(-1.5) + 2
-15 + 5 = -12 + 2
10 = 10
Therefore, the statement is true

Graph the image of this figure after a dilation with a scale factor of 2 centered at (2, 2) .
Use the polygon tool to graph the dilated figure.
Answer:
The points of the dilated figure would be at (-2, 10), (2, 6), and (-8, 4); an image of the figure is attached.
Step-by-step explanation:
First we translate the center of dilation and figure so the origin becomes the center of dilation.
Since the point (2, 2) is our center of dilation, we must translate it left 2 and down 2 to make the origin the center; this means we map every point
(x, y)→(x-2, y-2)
The scale factor of 2 means that each point will be multiplied by 2; this gives us the rule
(x, y)→(2x-4, 2y-4)
Lastly we will translate the figure right 2 and up 2 to move it back to its original position; this gives us the rule
(x,y)→(2x-4+2, 2y-4+2) = (2x-2, 2y-2)
The first point in the original figure, at the top, is (0, 6). Applying the transformation gives us
(0, 6)→(2*0-2, 2*6-2) = (0-2, 12-2) = (-2, 10)
The point on the right of the pre-image is (2, 4). Applying the transformation rule gives us
(2, 4)→(2*2-2, 2*4-2) = (4-2, 8-2) = (2, 6)
The point on the left of the pre-image is at (-3, 3). Applying the transformation rule, we have
(-3, 3)→(-3*2-2, 3*2-2) = (-6-2, 6-2) = (-8, 4)

What is the graph of the inequality
The inequality "x ≤ 5" means that the value of x is going to be less than or equal to the quantity 5.
Because of this, the correct answer on the graph would be a filled in dot (meaning starting at that quantity, rather than one less or one more than), and an arrow pointing to the left.
The value of x could be 5, 4, 3, and so on. Any quantity lower than, and including, 5 is a possible answer for the value of x.
The correct answer is the 2nd option.
Answer:
Graph represented by option B is the correct choice.
Step-by-step explanation:
We have been given an inequality [tex]x\leq 5[/tex]. We are asked to find the graph of the given inequality.
Our given inequality tells that solution is any value of x less than or equal to 5.
Since our given inequality has less than or equal to sign, then the number line will have a solid dot at [tex]x=5[/tex].
Since the values of x are less than or equal to 5, so the solution of the inequality will be numbers less than 5.
Since the numbers on the left side of a number line are less than number on right side, therefore, the graph represented by option B is the correct choice.

You are packaging expansion packs for the game of checkers. The table below lists the number of each part needed per expansion pack, as well as the number of each part that you have available.
Part Number in each pack Number available
People marker 6 287
6-sided die 3 143
Teleporter marker 7 341
You make as many expansion packs as you can. With the parts remaining, you could make 1 more expansion pack if you had:
A) 1 more people marker and 1 more die.
B) 1 more die and 1 more teleporter marker.
C) 1 more teleporter marker and 1 more people marker.
D) 2 more people markers.
E) 2 more teleporter markers
Answer: Option (A)1 more people marker and 1 more die.
Step-by-step explanation:
We have to pack expansion packs for the game of checkers in such a way such that there should be enough cards as per requirement.
So for that we have to find packs of each item by dividing each pack by part numbers and what is left after as remainder.
People marker =287 =6(47) + 5 ( as each pack of people marker contains 6 items)
6-sided die =143 = 3(47) + 2 (as each pack of 6- sided die contains 3 items)
Teleport-er marker=341 = 7(48) + 5 (as each pack contains 7 teleport-er marker)
So we can see that for 48th pack we have enough Teleport-er marker just we need one People marker and one 6-sided die. which is option A.
Given the quantities of game components available, we can form 47 complete expansion packs. We can form another pack if we had 1 more 6-sided die and 1 more people marker. Thus, the correct answer is option A.
Explanation:To answer the question, we first need to calculate how many complete expansion packs can be made with the available components:
People marker: We would divide the total number of available markers (287) by the number needed for each pack (6). Thus, a total of 47 full packs can be made with an extra 5 markers left over. 6-sided die: Dividing the total number of dice available (143) by the number needed for each pack (3), we get 47 full packs with 2 dice left over. Teleporter marker: Divided by 7 (the amount needed per pack), the 341 available teleporter markers would result in 48 full packs with 5 markers left over.
Given the available quantities, we can make a total of 47 complete packs. However, we'd have enough components to complete one more pack if we had 1 more die and 1 more people marker. Therefore, the correct answer is option A.
