Which set of angles are complementary

Mathematics
1 answer:
Deffense [45]2 years ago
6 0

Answer:

A. <ECF and <BCF

Step-by-step explanation:

Complementary angles are angles that add up to give 90°

m<BCE = m<BCA = 90° (right angles)

m<ECF + m<BCF = m<BCA

m<ECF + m<BCF = 90° (Substitution)

Therefore, <ECF and <BCF are complementary angles.

I would rather look at a frequency table because the exact numbers would be shown and it could tell you by how much and how frequently they’re increasing . A bar graph could do the same , but sometimes they could be grouped so it wouldn’t tell you the exact number .

Solve the system of linear equations using any method 6x+6y=-6, 5x+y=-13
Sergio [31]

Answer:

x=-3

y=2

Step-by-step explanation:

To solve this problem you can use the elimination method:

- Multiply the second equation by -6:

(-6)5x+y=-13\\-30x-6y=78

- Add both equations:

6x+6y=-6\\-30x-6y=78\\-------\\-24x=72\\x=-3

- Substitute the value of x into one of the original equations and solve for y:

6(-3)+6y=-6\\-18+6y=-6\\6y=12\\y=2

Having trouble with this question. Can someone help me.
vodka [1.7K]
For function one, the slope is already in mx+b form. The coefficient to x is the slope, so it is four in this case. For the second function we calculate the slope using rise over run. The rise is change in y and run is change in x, so 4/2= 2 slope. Four is greater than two so it has the greater rate of change. The answer is B
