Answer:
it is 4.6 sorry girl
Step-by-step explanation:
Part A: The discounted monthly fee is $22.49 (original cost of $29.99 multiplied by 75%, the amount the customer would pay since 25% is discounted.) Since you would also pay $44.99 for setup, your equation is $44.99+$22.49m
Part B: Add 1.08 (108%; the customer pays 100% of the cost plus 8% more for tax) to your equation for the sales tax. 1.08(44.99+22.49m)
Part C: Plug in 4 for m (m represents months).
1.08(44.99+22.49•4)
1.08(44.99+89.96)
1.08(134.95)
$145.75

49 = -7 (t + 1)
49 = -7t + 7
-7 -7
42 = -7t
÷ -7 ÷ -7
-6 = t
t = -7
Answer:
D
Step-by-step explanation:
Given a quadratic equation in standard form : ax² + bx + c = 0
We can solve for x using the quadratic formula
x² + 2x + 9 = 0 ← is in standard form
with a = 1, b = 2 and c = 9
x = ( - 2 ± 
) / 2
= ( - 2 ± 
) / 2
= (- 2± 
) / 2)
= (- 2 ± 
) / 2
= ( - 2 ± 4i
) / 2
= 
± 
= - 1 ± 2i → D
Answer:
B Equation 2 has the smaller y intercept
Step-by-step explanation:
Equation 1
y = -3x-2
This is in the form y= mx+b
The y intercept is b = -2
Equation 2
y = 1/2x-3
This is in the form y= mx+b
The y intercept is b = -3
-2 > -3
The smaller number is -3
