Answer: A (8,4)
Step-by-step explanation:
X=8
2x+y=20
2(8)+y=20
16 +y = 20
Y= 4
(8,4)
X = 96
100 137.4
137.4x=(100)(96)
137.4x=9600
137.4x/137.4=9600/137.4
x=70%
Answer:
15
Step-by-step explanation:
multiply both sides by 15
45x=675
Divide both sides by 45
x=15
Answer:
y = 5x - 4
Step-by-step explanation:
Step 1: Write known variables
m = 5
y = 5x + b
Step 2: Find <em>b</em>
6 = 5(2) + b
6 = 10 + b
b = -4
Step 3: Rewrite equation
y = 5x - 4
