2x2 - 3x - 2 = x + 4.check all of the solutions to this equation.-137(–1, 3)(3, 7)
Answer:
-1 and 3
Step-by-step explanation:
The equation can be solved using the quadratic formula, resulting in two possible solutions: x = (-3 + √25) / 4 and x = (-3 - √25) / 4.
Explanation:This equation can be solved using the quadratic formula. For an equation of the form ax² + bx + c = 0, we rearrange it to 2x² - 3x - 2 = x + 4.
Now, using the quadratic formula, we can solve for the values of x:
x = (-b ± √(b² - 4ac)) / (2a)
Substituting the values a = 2, b = -4, and c = -6 into the formula, we get:
x = (-(-3) ± √((-3)² - 4(2)(-2))) / (2(2))
After simplification, we have x = (-3 ± √(9 + 16)) / 4
Which gives us two solutions: x = (-3 + √25) / 4 and x = (-3 - √25) / 4

Answer:
Your answer is B or option 2.
Step-by-step explanation:
When doing scale factors, you will multiply. Always. To get from the original box to the second box, you will multiply by a scale factor of 5/8. An equation can model this. b=5/8a. (Let a = dimensions of original/blue box, let b = dimensions of second/green box).
Since you need to find the dimensions of the first/original box, you need to change b=5/8a to a= [something]. To do that, divide both sides by 5/8. You have b / 5/8 = a. The dimensions of the second box divided by the scale factor 5/8 is the dimensions of the first box. This also makes sense, because the green box looks smaller than the blue box. Hope I helped! This is a challenging subject to explain properly. ^_^"
oh yeah kekeke my name is pizaz/pzaz, what a coinkidink
The answer is D.
Since the original rectangle is bigger, we are going to divide the dimensions in the smaller triangle by the scale factor 5/8. An easy hint to look at in this question is an answer choice that both dimensions are bigger than the dimensions of the smaller rectangle. All the other choices are incorrect because the dimensions of the original triangle are not bigger than that of the smaller triangle which makes them false.

Susan's uncle from Japan promised to give her 41 g of gold. The local jewelry exchange will buy gold for $1286 per ounce.
The answer is $1851.84.
Given data:
Gold Susan has = 42 g
Price of gold = $1286 per ounce
Price of gold Susan has = ?
Solution:
1 Ounce = 28.34 g
1 g = 1/28.34 ounce
41 g = 1/28.34 * 41
= 1.44 Ounce.
Price of gold for 1 ounce = $1286
Price of gold for 1.44 ounce = 1286 * 1.44 = $1851.84

Jordan works in a science lab where he is studying the behavior of a certain unstable isotope. He has 240 milligrams of the sample, and the amount of the substance remaining in the sample decreases at a rate of 8% each day. After t days, there are less than 115 milligrams of the substance remaining. Which inequality represents this situation, and after how many days will the amount of the sample be less than 115 milligrams?
Answer:
After 8.82 days the amount of substance is less than 115 milligrams
Step-by-step explanation:
If x (t) represents the amount of substance in the sample after t days. So
[tex]x(t) = P_{t-1}- 0.08P_{t-1}[/tex] with [tex]t \geq 1[/tex]
Where Pt is the amount of substance in the sample on day t.
[tex]x (1) = 240 -0.08(240)\\ x (2) = 240 -0.08(240) - 0.8 [240 -0.08(240)][/tex]
Then x (t) can be written as:
[tex]x (t) = 240(1-0.08) ^ t[/tex]
After t days there are less than 115 milligrams of the substance, then:
x (t) <115
[tex]240(1-0.08) ^ t <115[/tex] This is the inequality that the situation represents.
Now we clear t.
[tex](0.92) ^ t <0.4792\\ t * ln (0.92) <ln (0.4792)\\\\ t>\frac{ln (0.4792)}{ln (0.92)}\\\\ t> 8,823[/tex]
After 8.82 days the amount of substance is less than 115 milligrams

If the blue radius below is perpendicular to the green chord and the segment BC is 7.6 units long, what is the length of the chord?
A. 15.2 units
B. 3.8 units
C. 30.4 units
D. 7.6 units
Answer:
The correct answer is A. 15.2 units
Step-by-step explanation:
The segment AB is congruent to the segment BC eg AB≅BC Why?
We can prove it with the triangle congruent theorem, postulate side-side-angle
We are watching triangle ΔABO and triangle ΔCBO, they are congruent
first element side OB=OB - common side
second element side OA=OC=r - radius of the circle
third element angle ∡ABO≅∡CBO=90°
According to the postulate side-side-angle we can conclude that triangles
ΔABO≅ΔCBO (triangles are congruent)
If they are congruent all of their elements are also congruent and therefore also
side AB=BC => AB+BC=AC, which is chord => 7.6+7.6=15.2 units
AC= 15.2 units ( chord )
Good luck!!!
Answer:
The correct answer is A. 15.2 units!
Step-by-step explanation:
Spencer wrote the following paragraph proof showing that rectangles are parallelograms with congruent diagonals. Quadrilateral R E C T is shown with right angles at each of the four corners. Segments E R and C T have single hash marks indicating they are congruent while segments E C and R T have two arrows indicating they are parallel. Segments E T and C R are drawn. According to the given information, quadrilateral RECT is a rectangle. By the definition of a rectangle, all four angles measure 90°. Segment ER is parallel to segment CT and segment EC is parallel to segment RT by the ________________. Quadrilateral RECT is then a parallelogram by definition of a parallelogram. Now, construct diagonals ET and CR. Because RECT is a parallelogram, opposite sides are congruent. Therefore, one can say that segment ER is congruent to segment CT. Segment TR is congruent to itself by the Reflexive Property of Equality. The Side-Angle-Side (SAS) Theorem says triangle ERT is congruent to triangle CTR. And because corresponding parts of congruent triangles are congruent (CPCTC), diagonals ET and CR are congruent. Which of the following completes the proof? Alternate Interior Angles Theorem Converse of the Alternate Interior Angles Theorem Converse of the Same-Side Interior Angles Theorem Same-Side Interior Angles Theorem
We have to prove that rectangles are parallelograms with congruent Diagonals.
Solution:
1. ∠R=∠E=∠C=∠T=90°
2. ER= CT, EC ║RT
3. Diagonals E T and C R are drawn.
4. Shows Quadrilateral R E CT is a Rectangle.→→[Because if in a Quadrilateral One pair of Opposite sides are equal and parallel and each of the interior angle is right angle than it is a Rectangle.]
5. Quadrilateral RECT is a Parallelogram.→→[If in a Quadrilateral one pair of opposite sides are equal and parallel then it is a Parallelogram]
6. In Δ ERT and Δ CTR
(a) ER= CT→→[Opposite sides of parallelogram]
(b) ∠R + ∠T= 90° + 90°=180°→→→Because RECT is a rectangle, so ∠R=∠T=90°]
(c) Side TR is Common.
So, Δ ERT ≅ Δ CTR→→[SAS]
Diagonal ET= Diagonal CR →→→[CPCTC]
In step 6, while proving Δ E RT ≅ Δ CTR, we have used
(b) ∠R + ∠T= 90° + 90°=180°→→→Because RECT is a rectangle, so ∠R=∠T=90°]
Here we have used ,Option (D) : Same-Side Interior Angles Theorem, which states that Sum of interior angles on same side of Transversal is supplementary.

Anna is given the equation 3 + 2x = 2x + 3 The replacement set is {2, 3, 4, 5} Anna says the solution is {3}, but the teacher marked her problem incorrect. Explain what the answer should be and why. Why do you think this is?
Answer:
The given equation has infinite number of solutions. This means that any real number can be considered a solution to the given equation.
Since the given replacement set {2,3,4,5} consists of real numbers, therefore, the whole set is considered as a solution to the given equation.
This is because, when solving the given equation for x, we will end up with 0 = 0, this means that whatever the value of x is, both sides of the equation will always be equal.
Explanation:
To solve for x, we need to isolate the x on one side of the equation.
This can be done as follows:
3 + 2x = 2x + 3 (subtract 3 from both sides)
2x = 2x (subtract 2x from both sides)
0 = 0
This means that whatever, the value of x is, both sides of the equation will be equal. This means that all real numbers are considered a solution for this equation.
Let's verify this using the given replacement set {2,3,4,5}:
For x = 2:
Left hand side: 3 + 2(2) = 3 + 4 = 7
Right hand side: 2(2) + 3 = 4 + 3 = 7
Both sides are equal.
For x = 3:
Left hand side: 3 + 2(3) = 3 + 6 = 9
Right hand side: 2(3) + 3 = 6 + 3 = 9
Both sides are equal.
For x = 4:
Left hand side: 3 + 2(4) = 3 + 8 = 11
Right hand side: 2(4) + 3 = 8 + 3 = 11
Both sides are equal.
For x = 5:
Left hand side: 3 + 2(5) = 3 + 10 = 13
Right hand side: 2(5) + 3 = 10 + 3 = 13
Both sides are equal.
Hope this helps :)
Find the x and y intercepts of the function
So when you look at the graphs, the functions always get close to x=0 but never actually touch it
So there are no x-intercepts
And for y, you just see where the point is passing the y-axis. In this case, the y-intercept is (0,-4)
So your answer is C :)
The intercepts for the given graph are:
x-intercept: none
y-intercept: (0, -4)
The correct option is the third one.
How to find the x and y intercepts?For a function y = f(x), we define the x-intercept as the value of x at which the function is zero, so:
f(x) = 0
And the y-intercept as the value that y takes when x = 0.
When we have a graph, we can just look at the points where the graph intercepts the correspondent axes.
In this particular case, we can see an asymptotic tendency to zero, so the function never intercepts the horizontal axis, there are no x-intercepts.
And we can see an y-intercept at y = -4
So the correct option is:
x-intercept: none
y-intercept: (0, -4)
