Answer:
Step-by-step explanation:
Let x represent the amount that Andre's neighbor pay him each week to mow the lawn.
Andre always gives a $2 donation to the food bank in weeks when he earns money. Since it will take him 5 weeks to earn the money for his dad's gift, his total donation for 5 weeks will be 2×5 = $10
Andre wants to save $40 to buy a gift for his dad. It means that the amount that he gets paid for mowing the lawn - his total donations in 5 weeks = the amount that he wants to save. Therefore,
x - 10 = 40
x = 40 + 10 = $50

Step-by-step explanation:
<u>Question 18</u>
- Diameter = Difference in y-coordinates
- Diameter = 12 - 2 = 10
- We know : Radius = Diameter/2
- Radius = 10/2
- Radius = 5 cm
- <u>(1) 5 cm</u>
<u></u>
<u>Question 19</u>
- 3x² - 34x - 24 = 0
- (3x + 2)(x - 12) = 0
- Solution set = {-2/3, 12}
- <u>(3) {-2/3, 12}</u>
The answer is 18.

[i]The range is the gap between the smallest value and the largest value. [/i]
The smallest is 68.
The largest is 86.
The gap between them is 86-68=18.
Answer:
Step-by-step explanation:
The point-slope form of an equation of a line:
m - slope
(x₁, y₁) - point
We have the slope m = 2 and the point (-7, 5) → x₁ = -7, y₁ = 5.
Substitute:
Convert to the slope-intercept form (y = mx + b):
<em>use distributive property</em>
<em>add 5 to both sides</em>
