HELP PLZZ ASAP !! a. The value of x is 6 , what is the value of y?

erastovalidia [21]

Answer:

a). y = 4.5

b) Scale factor = $\frac{3}{4}$

Step-by-step explanation:

a). Since, polygon Q is the scaled copy of polygon P

Both the figures will be similar.

Therefore, their corresponding sides will be proportional.

$\frac{x}{y} =\frac{4}{3}$

If x = 6,

$\frac{6}{y} =\frac{4}{3}$

y = $\frac{3\times 6}{4}$

y = 4.5

b). Since, polygon Q is the scaled copy of polygon P,

Polygon Q will be the image of preimage polygon P.

Scale factor = $\frac{\text{Length of a side of the image}}{\text{Length of a side of the preimage}}$

= $\frac{3}{4}$

Subtract the two equation from each other
-3x-7y=-66
-10x-7y=-24
--------------------
7x =-42
x=-6
by substituting in equation 1
(-3)(-6)-7y=-66
18-7y=-66
-7y=-84
y=12
so to check we substitute in the first equation

(-3*-6)-(7*12)=-66
18-84=-66
-66=-66
we check the second equations
-10(-6)-7(12)=-24
60-84=-24
-24=-24
