Answer:
Hello first one is 4.
Second one is 8
Step-by-step explanation:
First one is f(0). It means you should put zero in the place of x
0 is less than 5 so you should put zero in x+4=f(x)
For the second one do like the first one.
I hope you understand
Answer:
The answer is 76.
Step-by-step explanation:
≅ means to be equal to.
☆Angle DGE ≅ EGF.
Therefore, 3x + 8 = 5x - 12
☆Let's solve that equation.

We found the value of x which is 10.
☆Let's Now plug in.

and the other:

☆They asked for what the angle of DGF measured. So we would have to add both sides

☆The answer is 76
The formula d = rt gives the distance traveled in time t at rate r. A bicyclist rides for 1.5 hours and travels 25 miles.
d= D. 37.5 miles per hour
r= 25
t=1.5
25*1.5
=37.5
D.
37.5 miles per hour
Answer: x=6
The two angles shown in each are complementary because they add up to 90°.
10 & 12 would be supplementary to one another because they would add up to 180°.
Step-by-step explanation:
We know that on both 10 & 12 the angles add up to equal 90° so...
10. 8x+7x=90
15x=90
x=6
12. it's the same in pic as 10
The two angles shown in each are complementary because they add up to 90°.
10 & 12 would be supplementary to one another because they would add up to 180°.
