$175 × 0.09 = $15.75
$175 + $15.75 = $190.75
Answer:
See explanations below
Step-by-step explanation:
Given the system of equation
2x - 10 y = -30 ... 1
x - 5y = 20 ... 2
Step: From 2;
x = 20 + 5y ...3
Step 2: Substitute equation 3 into 1
2x - 10y = -30
2(5y+20) - 10y = -30
Open the bracket
10y + 40 - 10y = -30
10y - 10y + 40 = -30
0+40 = -30
40 = -30

Answer
Slope(m) = -1
Step by step explanation
Slope (m) = (y2 - y1)/(x2 - x1)
Here p1 = (-2, 3) and p2 (1, 0)
x1 = -2, y1 = 3, x2 = 1, y2 = 0
Now plug in the values in the slope formula, we get
m = (0 - 3) / (1 - (-2))
m = -3/(1 + 2)
m = -3/3
m = -1
Therefore, slope = -1
