1. B (opposite/hypotenuse)
2. C (opposite/adjacent)
Answer:
D. 45%
Step-by-step explanation:
there are 11 paintings and 9 paintbrushes, added together you have a total of 20 items. There are 9 paintbrushes and 20 items in total which is 9/20. 9/20 as a percentage is 45%
Answer:
Ax + By = C
5x + 4y = -20
a is 5, b is 4
Step-by-step explanation:
Find slope:
m = (y₂ - y₁) / (x₂ - x₁)
= (0 - (-5)) / (-4 - 0)
= 5 / -4
m = -5/4
Use m above and anyone point to find y-intercept, let's use (-4, 0):
y = mx + b
0 = -5/4(-4) + b
0 = 5 + b
b = -5
Slope intercept form using m and b from above:
y = mx + b
y = -5/4x - 5
Standard form Ax + By = C:
y = -5/4x - 5
5/4x + y = -5
5x + 4y = -20
Solution would be where the two lines intersect but they never do. They are parallel and never meet
Answer: no solution
