Answer:
Step-by-step explanation:
For equating the equations, you get
x2 + kx - 3x + 4 = 0 eq1
Setting the derivative of f(x) equal to 3 yields
f'(x) = 3
2x + k = 3 eq2
Now we substitute the value of k from eq2 into eq1.
x2 + x(3 - 2x) - 3x + 4 = 0
Solve for x from this equation. Then plug in the value of x into eq2 to solve for k
Answer:
290 + 5m = 985
Step-by-step explanation:
<u>Given information</u>:
- Initial payment = $290
- Total payment = $985
- Extra amount each month = m
- Length of rental = 5 months
From the <u>given information</u>, we can create the following <u>equation</u>:
Initial payment <u>plus</u> extra amount each month for 5 months <u>equals</u> total payment.
⇒ 290 + 5m = 985
<u>To solve the equation</u>:
Subtract 290 from both sides:
⇒ 290 + 5m - 290 = 985 - 290
⇒ 5m = 695
Divide both sides by 5:
⇒ 5m ÷ 5 = 695 ÷ 5
⇒ m = 139
Therefore, the extra amount George paid each month was $139.

Answer:
27, 20
Step-by-step explanation:
x + y = 47
x - y = 7
if we solve the second equation for 'x' we can:
let 'x' = y+7
substitute that expression for 'x' in the first equation to get:
y+7 + y = 47
2y = 40
y = 20
now find 'x':
x - 20 = 7
x = 27
