Answer:
- 13
Step-by-step explanation:
Given
- 2 + 3(1 - 4) - 2 ← evaluate parenthesis
= - 2 + 3(- 3) - 2 ← perform multiplication
= - 2 - 9 - 2
= - 13
Answer:
7.5'
Step-by-step explanation:
Use trigonometry.
Draw it out.
the hypotenuse is 15.
You want to find the adjacent side.
Use cosine (the adjacent over hypotenuse)
cos60=A/15
15cos60=A
7.5=A
4x-3y=-9
The first step is to isolate your y value.
Subtract 4x from both sides to get
-3y=-4x-9
Then, divide your whole equation by -3. This gives you y=4/3+3
To graph, plot (0, 3), or three on your y-axis to get your y-intercept.
For your slope, use the rise/run (go up 4, across 3)
You should have a positive slope.
