5a + 15 = 24b so,
10a + 30 = 48b,
sub to third equation,
10a + 30 + 35c = 49
10a + 35c = 19
perform elimination with second equation
10a + 45c = 21
10a + 35c = 19
________________-
10c = 2
c = 1/5
sub to second equation,
10a + (45)(1/5) = 21
10a + 9 = 21
10a = 12
a = 6/5
sub to first equation
(5)(6/5) - 24b = -15
6 + 15 = 24b
21 = 24b
b = 7/8
redo the calculations, correct me if I'm wrong
Answer: slope: -1/4. Y-intercept: 9/8.
Step-by-step explanation:
Use the slope-intercept form y = mx + b to find the slope m and y-intercept b
Answer:
q= -4
Step-by-step explanation:
First, simplify 4x+2y=5
2y=-4x+5
y=-2x+5/2
q+2 has to equal to -2
q = -4
