15/100*70000=$10500
$40000+$10500= $50,000
Answer:
Point - Slope Form: (y - 3) = 0.4(x - 5)
Slope - Intercept Form: y = 0.4x + 1
Step-by-step explanation:
Well if it's parallel, they have the same slope
Slope = 0.4
I'll do it in two forms:
Point - Slope Form: (y - 3) = 0.4(x - 5)
Slope - Intercept Form: y = 0.4x + b
3 = 2 + b
b = 1
y = 0.4x + 1
I might be wrong
(1/6) / (1/4) = x / 1....1/6 acre to 1/4 hr = x acres to 1 hr
cross multiply because this is a proportion
(1/4)(x) = (1/6)(1)
1/4x = 1/6
x = 1/6 * 4/1
x = 4/6 which reduces to 2/3....so she can mow 2/3 of an acre in 1 hr <=
Answer:
x ≈ - 9.41, x ≈ - 6.59
Step-by-step explanation:
Given
x² + 16x + 62 = 0 ( subtract 62 from both sides )
x² + 16x = - 62
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(8)x + 64 = - 62 + 64
(x + 8)² = 2 ( take the square root of both sides )
x + 8 = ± 
( subtract 8 from both sides )
x = - 8 ±
Hence
x = - 8 - ≈ - 9.41
x = - 8 + ≈ - 6.59
