Answer:
f(-2) = 5
Step-by-step explanation:
Step 1: Define
f(x) = -3 + 2x²
f(-2) is x = -2
Step 2: Substitute and Evaluate
f(-2) = -3 + 2(-2)²
f(-2) = -3 + 2(4)
f(-2) = -3 + 8
f(-2) = 5
Answer:
x - y = 1
Step-by-step explanation:
To begin, substitute m=1 and b=-1 into the slope intercept form y=mx+b.
y=x-1
Convert to the standard form by subtracting x to the other side.
-x + y = -1
In standard form, the coefficient of x cannot be negative. Multiply the entire equation by -1.
-1(-x + y = -1)
x - y = 1
180 - 142 = 38
w = 180 - (38+49)
w = 93
180 - (93 + 42) = 45
y = 180 - 131 = 49
t = 180 - (45 + 49)
t = 86
