Answer: x-intercept: y = -7
y-intercept: x = -5
Step-by-step explanation:
Rearrange to standard format: y=mx+b
-7x-5y=35
-5y= +7x + 35
y= -(7/5)x -7
b is the y-intercept b=-7
--
Find a value for x that makes y = 0, the x-intercept.
y= -(7/5)x -7
0= -(7/5)x -7
(7/5)x = -7
(5/7)*(7/5)x = (5/7)*(-7)
x = -5, the y-intercept

7v + 25 = 5(v + 7)
Simplify your answer as much as possible.
Answer:
v = 5
Step-by-step explanation:
Distribute on the left:
5 ( v + 7 )
( 5 x v ) + ( 5 x 7 )
5v + 35
7v + 25 = 5v + 35
Subtract 5v from each side:
2v + 25 = 35
subtract 25 from each side:
2v = 10
Divide each side by 2:
v = 5
Which is the equation of the line, in point-slope form, that has a slope of 2 and
passes through the point (4, -7)?
y+7= 2(x-4)
y-7 = 2(x+4)
x-7 = 2(x-4)
y-4 = 2(x+7)
Answer: y+7 = 2(x-4)
Step-by-step explanation: Point slope form is y − y1 = m(x − x1), where m is the slope and (x1,y1) is one known point on the line. We are told that m= 2 and (4,-7). Therefore:
(y − (-7)) = 2(x − (4))
y+7 = 2(x-4)

The monthly utility bills in a city have a mean of $70 and a standard deviation of $8. Find the s-scores that correspond to utility bills of $60, $71 and $9. What can you conclude
Z-Score for:
$60:
$71:
$92:
92 because I'm really good at math
The z-scores of the monthly utility bills for the value of x as $60, $71 and $9 are -1.25, 0.125, and 2.25 respectively.
What is Z-score?A Z-score helps us to understand how far is the data from the mean. It is a measure of how many times the data is above or below the mean. It is given by the formula,
[tex]Z = \dfrac{X- \mu}{\sigma}[/tex]
Where Z is the Z-score,
X is the data point,
μ is the mean and σ is the standard variable.
As it is given that the standard deviation of the monthly utility bills is $8, while the mean is $70. Therefore, the z-score can be written as,
A.) X= 60
[tex]Z = \dfrac{X- \mu}{\sigma}=\dfrac{60- 70}{8} = -1.25[/tex]
B.) X = 71
[tex]Z = \dfrac{X- \mu}{\sigma} = \dfrac{71- 70}{8}=0.125[/tex]
C.) X = 92
[tex]Z = \dfrac{X- \mu}{\sigma}= \dfrac{92- 70}{8}=2.25[/tex]
Hence, the z-scores of the monthly utility bills for the value of x as $60, $71 and $9 are -1.25, 0.125, and 2.25 respectively.

Describe the process for selecting points when dilating a curved figure.
When dilating a curved figure, you have to make sure to use a lot of points to produce a decent image of the original figure. You also have to make sure that the points you choose are not all concentrated in just one part of the figure.

the difference of a number and its absolute value.
Answer:
he sum of the first number and the square of the second number is 18. The difference between the square of the second number and twice the first number is 12.
I know the first set of equations would be x+y2=18 and y2−2x=12, and we can get x=2 and y=2 or y=−2.
My question is about how to understand difference when making equations. I know it means subtraction but would you ever use absolute values when making the equation?
For example, if I said the difference between a number x and 7 is 3, then wouldn't there be two answers? I would think of it as |x−7|=3 and then we could get two answers: x=10 and x=4. My rationale is that on the number line, the distance between either of my x values and 7 is 3.
In the quoted question I began with, then I could get the numbers of x=10 and y=22–√ or y=−22–√ but that's only if I did |y2−2x=12| and I don't feel that's right.

What is the ratio of A's to B's?
A B B B A A A
Answer:
4:3
Step-by-step explanation:
There are 4 A's and 3 B's, so the ratio would be 4:3.
The ratio would not be 3:4, because you are asking for A's to B's, and not B's to A's.
Answer:
4:3
Step-by-step explanation:
There are 4 A's in this set and only 3 B's. Often confused as 3:4, however, that would be the ratio of B's to A's. This ration can't be simplified either leaving it at 4:3.

-14 + 6b + 7 – 2b = 1 + 5b
8x + 4(4x + 3) = 4(6x + 4) - 4
I gotchu :)
1) 6r + 7 = 13 + 7r - Subtract 6r from both sides...
7 = 13 + r - Subtract 13 from both sides....
r = -6 Check answer (don't need this part)6(-6) + 7 = 13 + 7(-6)
-36 + 7 = 13 -42
-29 = -29 ( It works )
2) -14 + 6b + 7 - 2b = 1 + 5b - Combine like terms...
-7 + 4b = 1 + 5b - Add 7 to both sides....
4b = 8 + 5b - Subtract 5b from both sides....
-b = 8 - Divide both sides by -1
b = -83) 8x + 4(4x+3) = 4(6x + 4) - 4 - Distributive property
8x + 16x + 12 = 24x + 16 - 4 Combine like terms
24x + 12 = 24x + 12 - Both terms equal each other
0 = 0
Since both terms equal each other, all numbres fit.

Write the equation of the line that is parallel to y=-6x+2 and that has a y-intercept of 6
3y = x - 12
Y= 1/3X -4
parallel, perpendicular or neither
Answer:
PARALLEL
Step-by-step explanation:
The second equation, y = (1/3)x - 4, has already been solved for y. To compare the slopes easily, we need now to solve the first equation for y, obtaining y = (1/3)x - 4.
We see that these two lines have the same slope, m = 1/3, and thus conclude that these lines are PARALLEL.

Write an equation of the line in point-slope form that passes through the given points in the table. Then write the equation in slope-intercept form.
Answer:
[tex]y=\frac{1}{2} x-40[/tex]
Step-by-step explanation:
Slope interccept form: y=mx+b
(m= the slope, b= the y-intercept (the y value when x=0))
for every 2 x-values the y-value increases by 1. Slope is written as [tex]\frac{rise}{run}[/tex] or [tex]\frac{y_{1}-y_{2} }{x_{1}-x_{2}}[/tex] which is the change in the y-values divided by the change in x-values. You can find the slope by plugging in points.
[tex]\frac{(-42)-(-41)}{(-2)-(-4)} =\frac{1}{2\\}[/tex] so now you have [tex]y=\frac{1}{2}x+b[/tex]
b is whatever the value of y is when x=0. According to the table when x=0 then y=-40. The final equation is [tex]y=\frac{1}{2} x-40[/tex]
FI=6

calculate the length of GI
[tex]\\ \sf\longmapsto GI^2=FI(IH)[/tex]
[tex]\\ \sf\longmapsto GI^2=6(12)[/tex]
[tex]\\ \sf\longmapsto GI^2=72[/tex]
[tex]\\ \sf\longmapsto GI=\sqrt{72}[/tex]
[tex]\\ \sf\longmapsto GI=8.22[/tex]
If FI = 6 and IH = 12. The length of GI = 8.22.
How to estimate the length of GI?Given: FI = 6 and IH = 12
To estimate the length of GI
[tex]$\mathrm{Gl}^{2}[/tex] = FI (IH)
Simplifying the above equation, we get
[tex]$\mathrm{Gl}^{2}[/tex]= 6 (12)
Remove parentheses: (a) = a
Multiply the numbers then, we get
[tex]$6 \cdot 12=72$[/tex]
[tex]$\mathrm{Gl}^{2}[/tex] = 72
GI = [tex]$\sqrt{72}[/tex]
GI = 8.22
Therefore, the length of GI = 8.22.
