Answer: a=4 or a= −3, so you can use anyone of the answers.
Step-by-step explanation:
Solve Absolute Value.
|2a−1|=7
We know either 2a−1= 7or 2a−1 = −7
2a−1=7(Possibility 1)
2a−1+1=7+1(Add 1 to both sides)
2a=8
(Divide both sides by 2)
a=4
OR,
2a−1=−7 (Possibility 2)
2a−1+1= −7+1 (Add 1 to both sides)
2a= −6
(Divide both sides by 2)
a= −3
Therefor the answers are a=4 or a= −3

Answer:
y = 4x - 1
Step-by-step explanation:
slope: 7-3/2-1 = 4
y= mx+b
7= 4(2) + b
b= -1
y = 4x - 1
Solve for y on one of the questions. I'll do the second one. it will be y=3.25x+0.75. Plug it in for y in the other problem like this: -4.5x-2(3.25x+0.75). Solve. X= 5.5 and Y=18.625
Answer:
7pi or ≈21.98 cm²
Step-by-step explanation:
The area of the shaded and non shaded in the circle is pir^2 so pi3^2 so 9pi
the area of the 2 smaller circles is pi1^2*2 so 2pi
9pi-2pi=
7pi cm² =
7pi≈21.98 cm² (with pi as 3.14)
Answer:
4y - x = 20
Step-by-step explanation:
y-y1 = m (x-x1)
y - 6 = 1/4 (x - 4)
4y - 24 = x - 4
4y - x = 20
