Y = -2x - 4
x + 4y = 19
x + 4(-2x - 4) = 19
x + (-8x) - 16 = 19
-7x - 16 = 19
-7x = 35
-x = 5
x = -5
y = -2x - 4
y = -2(-5) - 4
y = 10 -4
y = 6
Solution set {-5, 6} (C)
Answer:
95 degrees aswell
Step-by-step explanation:
Answer:
Width = 3.75 feet
Length = 9.75 feet
Step-by-step explanation:
Given:
Length of fencing = 27 feet
Find:
Dimensions of the garden
Computation:
Assume
Width = x
So,
Length = x + 6
2(L+B) = Perimeter
2(x + x + 6) = 27
2(2x + 6) = 27
4x + 12 = 27
4x = 15
x = 3.75
Width = 3.75 feet
Length = 3.75 + 6 = 9.75 feet
Y intercept is 6 and the slope is -3
To solve this problem, we simply have to use ratio and
proportion.
We know that 15 gallons is consumed in 10 minutes
therefore the conversion factor is:
15 gallons / 10 minutes
Therefore in 77 minutes:
water consumed = (15 gallons / 10 minutes) * 77 minutes
<span>water consumed = 115.5 gallons</span>
