Answer:
20 dollars
Step-by-step explanation:
Answer:
y = 3
x = -3/4
Step-by-step explanation:
To get the initial value, we will make:
x = 0
y = 0
Then solve for the corresponding value of either x and y
Okay then, from the expression
y = 4x + 3
When x=0
y = 4 (0) + 3
y = 0 + 3
y = 3
When y=0
y = 4x + 3
0 = 4x + 3
4x = -3
x = -3/4
The initial value of the Linear function =
y = 3
x = -3/4

Step-by-step explanation:
Answer:
(f - g)(x) = 3x - 7
Step-by-step explanation:
(f - g)(x) = f(x) - g(x)
= 4x - 3 - ( x + 4 )
= 4x - 3 - x - 4
= 3x -7
Answer:
B.
200x + 800 = 1,600; 4 months
Step-by-step explanation:
Since 200 is the amount you pay each month, and x is the months, we pay 200 dollars for each month. We also add 800 because that was the initial price she paid, which is known. We then complete the equation by making it equal to 1600 dollars, which is the total amount she paid.
When we get 200x + 800 = 1,600, we solve for x.
First, we minus 800 on each side to isolate x. 200x=1600-800
Then, we simplify, 200x=800
Lastly we divide by 200 on both sides to completely isolate x and complete the equation. 200x=800÷200
Simplify, getting x=4 (months)
