3x + 5y = 29 first equation
y = -4x - 1 second equation
substitute the second equation to the first equation;
3x + 5(-4x - 1) = 29
-17x - 5 = 29
solve for x;
-17x - 5 = 29
-17x = 34
x = -2
substitute x = -2 into the second equation to find y;
y = -4x - 1
y = -4(-2) - 1
y = 8 - 1
y = 7
so;
x = -2, y = 7

Answer:
p = 1/8
Step-by-step explanation:
-3p + 1/8 = -1/4
-3p = -1/8 -14 /*8
-24p = -1 -2
-24p = -3 /:(-24)
p = 1/8
Slope is the change in y over the change in x:
Slope = (y2 - y1) / (x2-x1)
Replace the letters in the equation with the given information:
1/2 = (1 - -1) / (15 -r)
Cross multiply:
1 * (15-r) = 2 * (1- -1)
Simplify:
15 -r = 4
Subtract 15 from each side:
-r = -11
Because r is negative, you need to multiply both sides by -1 to make r positive:
r = 11
