Answer:
y=1/2x+8
Step-by-step explanation:
grab 2 points in this case (4,10) and (0,8)
use rise over run formula so it rises 2 and goes over 4
so 2/4 then simplify and you get 1/2
and the y intercept is 8 because thats when the slope touches the y line
so using the equation y=mx+b when m is slope and b is y interecpt
the answer should be y=1/2x+8
Answer:
The solution of the system of equations will be:
Step-by-step explanation:
Given the system of equations:
Isolate 
for 
, 
Isolate x for 
, 
Therefore, the solution of the system of equations will be:
You can eliminate A and C because the length is longer than the width. Then just use the process of elimination
24 × 18 = 432ft², so D is incorrect
12 × 18 = 218ft², so B is correct
Not sure about h=the second though
Answer:
7
Step-by-step explanation:
∑ᵢ₌₁³ (4 × (½)ⁱ⁻¹)
This is the sum of the first 3 terms of the sequence.
The first 3 terms are:
4 × (½)¹⁻¹ = 4
4 × (½)²⁻¹ = 2
4 × (½)³⁻¹ = 1
So the sum is:
∑ᵢ₌₁³ (4 × (½)ⁱ⁻¹) = 4 + 2 + 1 = 7
