If x=16-4y then in your other equation 3x+4y=8 you can put that where x is to get:
3(16-4y)+4y=8
Then multiply brackets to get:
48-12y+4y=8
Simplify:
48-8y=8
Rearrange:
40=8y
Divide through by 8:
y=5
Then put y=5 back into x=16-4y to get x:
x=16-4(5)
x=16-20
x=-4
Answer:
1 is the fist picture
2 is the second picture and if u calculate them both equals to 3 so that why the slope cross the same way
Answer:
g(x) = 7x^2
Step-by-step explanation:
Given a function f(x), the function kf(x) is stretched by a factor of k. In this case, if we stretch the function f(x) = x^2 by a factor of seven, the new function is going to be the base function multiplied by 7, as follows:
g(x) = 7x^2
"77.25 in²" ..............
All will apply except for (A, C, and E) because those lengths are less than 4/6. So (B, D and F) are the correct answers.
