Measure B is 90 because 17x+=180/2
and x=5
when you plug that into 17x+5 you get 90
Answer:
26
Step-by-step explanation:
Problem: f(x) = 28 + x + 7
Plug in f(-9)
New equation: f(-9) = 28 + (-9) + 7
Simplify: f(-9) = 26
<u>Answer: f(-9) = 26</u>
Answer:
95 feet
Step-by-step explanation:
In Death Valley, hiking man starts at 65 feet above sea level and then descends 30 feet below sea level. The man needs 65 feed to reach sea level, then from there he travels 30 feet more.
Thus he travels the sum of this distances, i.e 65+30 = 95 feet
Answer:
x = -11
Step-by-step explanation:
3x - 4 + 2(x - 5) = 9x + 8 - 2x
3x - 4 + 2x - 10 = 9x + 8 - 2x
3x + 2x - 9x + 2x = 8 + 10 + 4
- 2x = 22
- x = 22/2
- x = 11
x = - 11
Answer:
Slope m=2, y-intercept b=5 --> y=2x+5
Slope m=3, y-intercept b=5 --> y=3x+5
Slope m=5, y-intercept b=4 --> y=5x+4
Step-by-step explanation:
The slope number goes with x, and the y-intercept gets either added or subtracted from the end of the equation depending on weather it's positive or negative. (subtracted if it's negative and added if it's positive)
