Answer: 1/9
Step-by-step explanation:
The slope of this line is -9. The slope of the perpendicular line is the opposite reciprocal. The reciprocal of -9 is -1/9, the opposite of that is 1/9
Answer:
So first subtract 14 from 32
That means that -6y+4y = 18
Simplify the left side 4-6=-2
-2y = 18
Divide by -2
<u>-9 = y</u>
Step-by-step explanation:
The amount of money Jade and chet will have to purchase the app is $11.6
<h3>How to solve equation?</h3>
- Jade = 8 + 2x
- Chet = 4x + 6
Where,
x = $2.50
Amount each earned:
Jade = 8 + 2x
= 8 + 2(2.50)
= 8 + 5
= $13
Chet = 4x + 6
= 4(2.50) + 6
= 10 + 6
= $16
Combined earnings = $13 + $16
= $29
Amount planned to save = 40% of combined earnings
= 40% × $29
= 0.4 × 29
= $11.6

Step-by-step explanation:
(9m + 4)² - (9m - 4)² ← expand both factors using FOIL
= 81m² + 72m + 16 - (81m² - 72m + 16) ← distribute parenthesis by - 1
= 81m² + 72m + 16 - 81m² + 72m - 16 ← collect like terms
= 144m
= 72(2m)
which is divisible by 72 for all m
Answer:
Step-by-step explanation:
-7k = 0
Divide both sides by (-7)
k = 0
17) c - 4 = -23
Add 4 to both sides
c - 4 + 4 = -23 + 4
c = - 19
