Answer:

x=10, y=12

Step-by-step explanation:

You have to use scale factor. 6 is 2/3 of 9. Using this, we can say that x is 2/3 of 15. So, x must be 10 (because 10 is 2/3 of 15). We can also say that y is 2/3 of 18. So, y has to be 12 (because 12 is 2/3 of 18).

Answer:

x=10, y=12.

Step-by-step explanation:

You are making all sides of the triangle smaller by a scale factor of 2/3, because 9*2/3=6. For x, we can do 2/3*15, which equals 10. For y, we can do 2/3*18, equalling 12.

How do i solve this kind of problem
Advocard [28]

Answer:

y=x-2

Step-by-step explanation:

to get -2 to -4 you would have to add -2

if we follow the pattern of subtracting 2 then you would see that -2 is b sense we are subtracting.

The m value doesn't have to change so we would leave the x how it is

The goal for this question is to find the pattern the numbers share though out the table.

What is the fully factored form of the expression 16x^2 - 49y^2
podryga [215]

Answer:

(4x + 7y)(4x - 7y)

Step-by-step explanation:

Rewrite 16 as 4^2

= 4^2x^2 - 49y^2

Rewrite 49 as 7^2

= 4^2x^2 - 7^2y^2

Apply the Exponent Rule Pt 1  ((a^m*b^m =(ab)^m))

= (4x)^2 - 7^2y^2

Apply the Exponent Rule Pt 2

= (4x)^2 - (7y)^2

Apply Difference of Squares Formula (( x^2-y^2 = (x + y)(x - y)

= (4x + 7y) (4x - 7y)
