-7x+4y=24, 4x-4y=0 substitution

1 answer:

8 0

The first one: -7(x) + 4(y) = 24
The second one: 4(x) - 4(y) = 0

4y - 7x = 24 which is reduced to a negative
(-4y + 4x = 0 )

4(x) = 4(y)

-7(y ) + 4(y) = 24
- 3(y) = 24

3(y) = - 24

y-intercept: - 8
x-intercept: -8

The X & Y intercept is: -8, -8

IgorC [24]

Answer:

3/16

Step-by-step explanation:

Monica has a 24-inch square frame.

There are 4 equal sides.

Hence, length of each side=24/4 inch

= 6 inch

She paints 3/4 of one side of the frame blue.

i.e. she paints $\dfrac{3}{4}\times 6$ inch

Total part to be painted=24 inch

Hence, fraction of the frame Monica painted blue is:

$\dfrac{3\times 6}{4\times 24}\\ \\= \dfrac{3}{16}$
