Answer:
approximately 180.2
Step-by-step explanation:
238.2 - (10 times 5.8) = x
238.2 - 58 = x
180.2 = x
Answer:
Step 2
Step-by-step explanation:
Step 2 should be Addition Property of Equality, to remove -3 from the left equation.
4b + 2b -3 = -21
6b - 3 = -21 (Combined like terms)
6b = -18 (Addition Property of Equality)
b = -3 (Division Property of Equality)
Answer:
113,28,22 in that order
Step-by-step explanation:
Domain: x>-5 ; It goes on from -5.
Range: y>-1 ; It goes on from -1.
Function: Slope is 6/7 ;
<h3><u><em>
y=6/7 x , when x>-5</em></u></h3>
Answer:
The everage rate of change over the interal 4 ≤ x ≤ 8 will be: 60
Step-by-step explanation:
Given the function
Interval : 4 ≤ x ≤ 8
or
Interval = [4, 8]
so
at x₁ = 4, f(x₁) = 2ˣ - 12 = 2⁴ - 12 = 16-12 = 4
at x₂ = 8, f(x₂) = 2ˣ - 12 = 2⁸ - 12 = 256 - 12 = 244
Using the formula to determine the average rate of change over the interval 4 ≤ x ≤ 8 wil be:
Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]
= [244 - 4] / [8-4]
= 240 / 4
= 60
Therefore, the everage rate of change over the interal 4 ≤ x ≤ 8 will be: 60
