Please help. You will get some points.

1) x: small #; y: large #

4y = 7x

x + y = 22

-7x + 4y = 0

x + y = 22

---multiply the second equation by -4

-7x + 4y = 0

-4x - 4y = -88

solve

-11x = -88

x = 8

---substitute with any of the equation above i chose the very first one

4y = 7(8)

4y = 56

y = 14

x = 8; y = 14

2) x = small #; y = large #

y - x = 15

5x = y - 9

after rearranging, solve

-x + y = 15

5x - y = -9

-4x = 6

x = -1.5

substitute

-(-1.5) + y = 15

1.5 + y = 15

y = 13.5

x = -1.5; y = 13.5

3) x = lemon cream; y = fudge cookie

3x + 2y = 400

2x + 3y = 425

multiply the first equation by -2, multiply the second equation by 3

-6x - 4y = -800

6x + 9y = 1275

solve

5y = 475

y = 95

substitute

3x + 2(95) = 400

3x + 190 = 400

3x = 210

x = 70

x = 70; y = 95

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

can i see the following ?
