For both problems, we can use the section formula.
1) 
2) 
1500
600 per hour
It starts at 1500 and then after one hour
It go up to 2,100 then 2700
Answer:
15
Step-by-step explanation:
Angle c is 180 - 146 = 34
All 3 angles add to 180:
(5y + 3) + (4y + 8) + 34 = 180
9y + 45 = 180
9y = 135
y = 15
Answer:
x = {-1/5, 1}
Step-by-step explanation:
(5x - 2)² - 1 = 8
Add 1 to both sides
(5x - 2)² = 9
Take the square root of both sides
5x - 2 = ±3
------------------------------
<u>Solution I</u> for 5x - 2 = +3
5x - 2 = 3
add 2 to both sides
5x = 5
Divide both sides by 5
x = 1
------------------------------
<u>Solution II</u> for 5x - 2 = -3
5x - 2 = -3
add 2 to both sides
5x = -1
Divide both sides by 5
x = -1/5
-------------------------------
x = {-1/5, 1}
