Answer: B 10 miles in 1/5 hour
Step-by-step explanation:
Variables x, y, and z are integers such that xyz > 0. If xy=30, x/z=2/3, and z=9, what is the value of y?
Explanation:
Plug z = 9 into the second equation and solve for x.
x/z = 2/3
x/9 = 2/3
x = 9*(2/3)
x = 18/3
x = 6
This leads to
xy = 30
y = 30/x
y = 30/6
y = 5

X= 164, -8, 4, 164
Y= -99, -60, -57, -17
Which equation represents the same relationship?
A. y + 17= 1/4(x - 164)
B. y - 17= 1/4(x + 164)
C. y + 164= 1/4(x - 17)
D. y - 164= 1/4(x + 17)
The Equation of line is y + 17= 1/4(x - 164).
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
X= 164, -8, 4, 164
Y= -99, -60, -57, -17
Using slope
= ( -17 + 57 )/ ( 164 - 4)
= 40/ (160)
= 1/4
So, Slope- intercept form
y + 17 = /4 ( x- 164)

Step-by-step explanation:
This shifts the graph down 1 unit, reflects over the x axis, then vertically dilates by a factor of 2.
=============================================================
Explanation:
Refer to the figures below. The screenshots may be a bit on the big side, so brainly might attempt to reduce the size. To fix this, click on the magnifying glass to get a better look. There are 4 images in total.
Figure 1 is the original graph your teacher gave you.
Figure 2 shows the translation of the parabola 1 unit down. This aligns the right piece of the red parabola to the green V curve. This junction location is (1,0).
Afterward, in figure 3, we reflect the parabola over the x axis to have the left endpoint of the parabola (-3,8) move to (-3,-8). Unfortunately the (-3,-8) doesn't match up with the right most piece of the blue cubic curve.
Luckily, a quick fix is to double the y coordinate from -8 to -16 and the two pieces match perfectly. The other junction is (-3,-16). This is shown in figure 4.
To summarize, we did these transformations in the order presented.
Shift down 1 unit (figure 2)Reflect over the x axis (figure 3)Vertically stretch or dilate by a factor of 2 (figure 4)--------------
Now to shift down 1 unit, we subtract 1 from each g(x) output.
Therefore, we go from g(x) to g(x)-1
Reflect over the x axis to get -(g(x) - 1) = -g(x) + 1
Lastly, we double everything when applying the dilation mentioned to end up with the final answer: -2*g(x) + 2
You can use a tool like GeoGebra to check your work. It's the app I used to make the figures shown below.

Which is greater: 3x3/2 or 3X2/3 Why?
Answer:
3X3/2 is greater
Step-by-step explanation:
Go left to right and solve the equations.
Equation 1: 3 multiplied by 3 is 9. 9 divided by 2 is 4.5
Equation 2: 3 multiplied by 2 is 6. 6 divided by 3 is 2
Equation 1 yields a greater value.
Answer:
The 3x3/2 is greater than 3x2/3
Step-by-step explanation:
Here is a simple tip when solving these questions:
Decimal form is always great to use because you get the answer instantly instead of finding a common denominator while involving fractions.
Let's solve 3x3/2.
First, do 3x3 which is 9.
Your problem should be 9/2
Now, you could do this as a mixed number but like I said there shall be more work so you should do 9/2 on a calculator or divide but involve decimal point if you have a remainder.
9 divided by 2 is 4.5
9/2 is 4.5 (Above is the interpretation in words)
Next, do 3x2/3
The same thing as last, do 3x2 first.
Your problem should be 6/3
If we know our division facts then 6 divided by 3 is 2.
Lastly, compare our numbers.
The 3x3/2 is 4.5 and the 3x2/3 is 2
Line the numbers up:
4.5
2.0
The tens digit clearly shows that 4 is greater than 2.
Therefore,
The 3x3/2 is greater than 3x2/3

Which of the following is the square of a binomial?
A)m^2-mn+n^2
B)c^2-2cd+d^2
C)16x^2 + 9y^2
D)a^2+b^2
c^2-2cd+d^2 = (c-d)^2
We can verify this with the following steps
(c-d)^2 = (c-d)(c-d)
(c-d)^2 = c(c-d) - d(c-d)
(c-d)^2 = c^2-cd-cd+d^2
(c-d)^2 = c^2-2cd+d^2
