$0.50 plus $1.50 < $25; x < 47 miles
Is this it ???? I hope i helped
Answer:
12.5 or less
Step-by-step explanation:
Let x b the number of miles Sharon travels, we can write an expression relating the amount she spends. We can add the cab flat fee and the amount per mile. So there:
[tex]=0.5+1.50=2[/tex]
So let that total cost per mile be less than equal to the amount the Sharon can spend:
2x≤25
We can determine x:
x≤12.5
Sharon can travel 12.5 or less
if axb=0, then a=0 or b=0
3x=0
Answer:
The given equation is
ax b= 0,
As we see that, it is a linear equation in one variable containing two constant.
So , a≠ 0 [then equation has no meaning.If a=0 , then [tex]0 \times x=0[/tex], which is meaningless]. ∴ a=0 is incorrect.
Similarly , b≠ 0 [ Reason same as above]. ∴b=0 is incorrect.
⇒3 x=0
⇒x=0 is the correct response.
Let me explain by this giving an example
⇒5 x=0
⇒ x=0 but 5≠0
So, x=0 or 3 x=0 is correct response.

If y = 7x, what happens to x when y is increased by 5 times its original value?
A) x decreases 5 times its original value
B) x increases to 11/5 its original value
C) x also increases 5 times its original value
D) x decrease to 4/5 of its original value
B) Because to find the value of x and y you have to divide x by 7 to make it x and the multiply 7 by y because you divided by the opposite side, which is x.
Complete the mapping of the vertices of ΔDEF. D(2, –4) → D' E(1, –1) → E' F(5, 1) → F' What is the rule that describes a reflection across the line y = x? rx = y(x, y) →
D(2, –4) → D' = (-4, 2)
E(1, –1) → E'= (-1, 1)
F(5, 1) → F'=(1, 5)
What is the rule that describes a reflection across the line y = x?
rx = y(x, y)= (y, x)
The rule which describes a reflection across the line is y(x, y) --> (y, x) and the mapping of the vertices of ΔDEF is (-4, 2)D', (-1, 1)E' , (1, 5)F'.
What is reflection?The reflection of a plane or shape is flipping the original figure with respect to a reference line.
The following steps are used to for reflecting a shape-
Select the shape which has to be reflected.Select a base line or reference line over which the shape has to be reflected.Mark the corners of the shape at the equidistant from the reference line as the original shape has, but in the opposite direction.The reflected shape is now is facing the opposite direction.The rule that describes a reflection across the line says that when your reflect a point across the line say y=x. Then the coordinates of x and y are interchanged as,
y(x, y) → (y, x)
Now let's complete the mapping of the vertices of ΔDEF using the above rule. For this, change the places of x and y coordinate as,
D(2, –4) → (-4, 2)D'
E(1, –1) → (-1, 1)E'
F(5, 1) → (1, 5)F'
Thus, the rule which describes a reflection across the line is y(x, y) --> (y, x) and the mapping of the vertices of ΔDEF is (-4, 2)D', (-1, 1)E' , (1, 5)F'.

(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

Is -6.809 more or less than -6.812
it is more because of the negative.
In mathematics, when dealing with negative numbers, the number closer to zero is greater. Thus, -6.809 is greater than -6.812 because it's closer to zero.
Explanation:In the field of mathematics, when you're dealing with negative numbers, the number that is closer to zero is always greater. Here, we have the numbers -6.809 and -6.812. Looking carefully, -6.809 is closer to zero than -6.812. Hence, -6.809 is greater than -6.812.
Let's understand it with a simpler example. If we have -3 and -5, even though 5 is greater than 3, -5 is lesser than -3 because it's further away from zero.

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]

Step-by-step explanation:
Leeann works 20 hours per week and makes $15 per hour
Her weekly income = 20 × 15 = $300
In one year = 52 weeks

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.

The value of x is equal to 21.
The equation, twelve is the same as two-thirds a number diminished by two - True
Explanation:To determine if twelve is the same as two-thirds of a number diminished by two, we can set up an equation. Let's represent the number as 'x.' According to the statement, twelve is equal to two-thirds of x diminished by two. Mathematically, this can be written as:
12 = (2/3)x - 2
To solve for x, we need to isolate it on one side of the equation. First, we can add 2 to both sides:
14 = (2/3)x
Next, we can multiply both sides by 3/2 to eliminate the fraction:
14 * (3/2) = x
21 = x
Therefore, the number in question is 21. To confirm, we can substitute x back into the original equation:
12 = (2/3)(21) - 2
12 = 14 - 2
12 = 12
Since the equation is true, we can conclude that the statement is True.

find x if a =13 and C = 47 need help
So you're using the Pythagorean theorem which is a^2 + b^2 = c^2... so if you dont have b you can manipulate the equation. That equation is c^2 - a^2= b^2, so you square 47 which is 2209 and then square 13 which is 169... you do 2209-169 and that equals 2040, then you do the square root of that which is 45.166359 that can be simplified to 45 or two decimal points 45.167.
