Answer:
$8.33 per hour
Step-by-step explanation:
4(8.25) = $33 earned at the sporting goods store
2(10) = $20 earned shoveling snow
$53 = total earned in 6 hr.
53/6 = $8.33 per hour to nearest penny
$53/6 = exact amount earned per hour
A point of intersection is a point where two lines or curves meet.
There are zero points of intersection.
Given
The equations are;
<h3>What is the point of intersection?</h3>
A point of intersection is a point where two lines or curves meet.
There are two methods to find a point of intersection graphically by graphing the curves on the same graph and identifying their points and another one is to solve the equation and find the value of x and y.
Adding both the equation
Substitute the value of y in the equation
Hence, there are zero points of intersection.

They are equal
(-16)-(-4)
*negative and negative make a positive
-16+4= -12
-16+4=-12
They both make -12. They both are equal
Answer:
tan²x + 1 = sec²x is identity
Step-by-step explanation:
* Lets explain how to find this identity
∵ sin²x + cos²x = 1 ⇒ identity
- Divide both sides by cos²x
∵ sin x ÷ cos x = tan x
∴ sin²x ÷ cos²x = tan²x
- Lets find the second term
∵ cos²x ÷ cos²x = 1
- Remember that the inverse of cos x is sec x
∵ sec x = 1/cos x
∴ sec²x = 1/cos²x
- Lets write the equation
∴ tan²x + 1 = 1/cos²x
∵ 1/cos²x = sec²x
∴ than²x + 1 = sec²x
- So we use the first identity sin²x + cos²x = 1 to prove that
tan²x + 1 = sec²x
∴ tan²x + 1 = sec²x is identity
