Answer:
16
Step-by-step explanation:
5y=6x+16...(I) and 9x=7y-20....(ii)
Using substitution method:
Multiply equation ii by 5
45x=35y-100
Substitute (I) into ii
45x=7 * 5y - 20
45x=7(6x+16)
45x=42x+112
45x-42x=112
3x=112......…….......
5y=6x+16
5y=2*3x+16
5y=2*112+16
5y=224+16
5y=240
Divide both sides by 5
y=48
3x-2y
112-2*48
112-96

Answer:
Slope is 1.5 and y-intercept is 11
Step-by-step explanation:
It's in the equation
Complementary angles mean that they would add up to 90 degrees.
That means 2x-0 and 3x-10 added up together would equal to 90 degrees.
2x-0+3x-10 = 90
5x-10 = 90
5x = 100
x = 20
