Answer:
33 degrees
Step-by-step explanation
I used arcos, ∠A = arccos((a2 + b2 - c2)/2ab)
= 0.5795 rad = 33.203° = 33°12'11"
3 x 5 = 15
5 x 1 = 5
15/5 = 3
3, Hope this helps!
Slope intercept form is y = mx + b
First step: Pick two coordinates from the graph. I chose: (0, -3) and (-2, 5).
Second step: Now use the formula y2-y1 over x2-x1 to calculate the slope. It should look like this: 5 - - 3 over -2 - 0 = -8/2. Simplify it to -4.
Third step: Write this in slope intercept form.
—> FINAL answer: y = -4x - 3.
Using long division, we get
2x-5
x+3 | 2x^2+x-15
- (2x^2+6x)
_________
-5x-15
-(-5x-15)
________
0
2x-5 is your answer
The answer is A. because the first part shows the ratio 3:2 and the other 2 shows equivalent ratios.
