The standard form for y=-7+6x is Ax + By = C
For c using proportionality of corresponding sides you can writing
(3c+4) 9
--------- = -------
20 15
(3c+4) 3
---------- = ------ cross multiple
20 5
5(3c+4) = 20*3 divide both sides by 5
3c+4=4*3
3c+4=12
3c = 8
c = 8/3
for d you can writing
(2d-3) 9
--------- = ------
12 15
(2d-3) 3
--------- = ------- cross multiple
12 5
5(2d-3) = 12*3
10d -15 = 36
10d = 51
d = 51/10
d = 5,1
hope helped
i have no ideaaaaa HAHAHAHA
Answer:
Step-by-step explanation:
Let the numbers are 2x and 2x + 2.
<u>We have:</u>
- (2x + 2x + 2)² = (2x)² + (2x + 2)² + 48
- 4(2x + 1)² = 4x² + 4(x + 1)² + 48
- (2x + 1)² = x² + (x + 1)² + 12
- 4x² + 4x + 1 = x² + x² + 2x + 1 + 12
- 2x² + 2x - 12 = 0
- x² + x - 6 = 0
- (x - 2)(x + 3) = 0
- x = 2, x = -3
<u>The numbers are:</u>
