7=3/8x-2

move -2 to the other side

sign changes from -2 to +2

7+2=3/8x-2+2

7+2=3/8x

9=3/8x

multiply both sides by 8/3 to get x by itself

9(8/3)=3/8x(8/3)

pretend that 9 has a denominator which is 1

cross out 9 and 3, divide by 3 and then becomes 3*8=24

answer:

x=24

Answer:

x = 24

Step-by-step explanation:

Firstly, isolate x by adding 2 to both sides.

9 = 3/8x

Then, multiply 8 to both sides.

72 = 3x

Then, divide both sides by 3.

24 = x

5x=4y+8 3y=3x-3 using elimination

suter [353]

Let's rewrite the equation with x and y on the left side of the equal sign.
5x-4y=8 --------(1)
3x-3y=3---------(2)
Divide equation (2) by 3,
x - y= 1
now we have,
5x-4y = 8 --------(1)
x - y = 1 ---------(2)
To eliminate x, multiply equation (2) by 5. This makes both the coefficients of x to be 5. Subtract the second equation from the first equation.
5x - 4y = 8
(2) * 5 5x - 5y = 5
(-) (+) (-)
----------------
0x +y =3
Therefore, y=3
Substitute the value of y, in any one of the two equations. Let's substitute y in the second equation.
x-3=1
x=4
x=4 and y=3

Find the mean of this data set: {– 78, -12, 3, – 44}

blagie [28]

Answer:

Answer: A. -32.75

$\dashrightarrow{ \tt{mean = \frac{ \sum f(n)}{n} }} \\$

• f(n) are the values of the set

• n is the number of items

$\dashrightarrow \: { \tt{mean = \frac{ - 78 + ( - 12) + 3 + ( - 44)}{4} }} \\ \\ \dashrightarrow \: { \tt{ \frac{ - 131}{4} }} \\ \\ \dashrightarrow \: { \boxed{ \tt{mean = - 32.75}}}$

HURRRY PLEASE. Find the focus and directrix of the parabola with the equation y2=18x

Lady_Fox [76]

Been a while but I'm gonna try..! Okay!
For the Focus use the vertex to find it. (9/2 , 0)
For the directrix I believe it is. x = -9/2

Which composition of similarity transformations maps polygon ABCD to polygon A'B'C'D'?

Elina [12.6K]

Hey there!

Unless the smaller object was rotated 360° (in which case the rotation wouldn't have to be mentioned), you can see that all of the lines are still in the same place and that it wasn't rotated at all. This eliminated any answer option that mentions a rotation, which is A and C.

Also, if you count the units of one of the straight lines – for example, line AB and A'B' – you can see that the smaller object is four times smaller than the larger object. In the case of line AB and A'B', line AB is 8 units long and A'B' is 2 units long. This means that the scale factor is $\frac{1}{4}$ .

Lastly, the smaller object was moved from its initial location, which would be in the center of the larger object if it wasn't moved after being scaled down.

The answer will be B, "a dilation with a scale factor of $\frac{1}{4}$ and then a translation."

Hope this helped you out! :-)
