4. 28÷2=14 every 1 nurse
5. 5÷2= 2.5 every 1 pound
1. You could plug this into the calculator as either 70% of 156.33 or 0.7 × 156.33, but either way you know the discount is going to be $109.43
2. We got the discount, so all you have to do is subtract it from the original. 156.33 - 109.43 = $46.90 which is the sale price! I hope this helps
Answer:
y = 3x + 1
Step-by-step explanation:
(0,1) so that is the b
the rate of change is 9/3 so the m is 3
Its option C
40 × (¹/₄)⁰ = 40
40 × (¹/₄)¹ = 10
40 × (¹/₄)² = 5/2
40 × (¹/₄)³ = 5/8
40 × (¹/₄)⁴ = 5/32
Answer:
x = - 7, x = 3
Step-by-step explanation:
To find the zeros let y = 0, that is
- x² - 4x + 21 = 0 ( multiply through by - 1 )
x² + 4x - 21 = 0
Consider the factors of the constant term (- 21) which sum to give the coefficient of the x- term (+ 4)
The factors are + 7 and - 3, since
7 × - 3 = - 21 and 7 - 3 = + 4, thus
(x + 7)(x - 3) = 0
Equate each factor to zero and solve for x
x + 7 = 0 ⇒ x = - 7
x - 3 = 0 ⇒ x = 3
