Answer:
A. 
Step-by-step explanation:
The equation in slope-intercept form, 
, can be created to be used in finding Jack's pay. We need to find the slope (m) and the y-intercept (b) of the linear function.
Using two points (1, 18), and (1.5, 23), find the slope (m):
Slope (m) = 
Find b, by substituting x = 1, f(x) = 18, and m = 10 into .
Subtract 10 from each side
Substitute m = 10 and b = 8 into .
✅Thus, the linear function that can be used to find Jack's pay would be:
Answer:
AB = 4 cm
Step-by-step explanation:
The tangent and secant are drawn from an external point to the circle.
Then the square of the measure of the tangent is equal to the product of the external part of the secant and the entire secant.
let AB = x, then
x(x + 5) = 6²
x² + 5x = 36 ( subtract 36 from both sides )
x² + 5x - 36 = 0 ← in standard form
(x + 9)(x - 4) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 9 = 0 ⇒ x = - 9
x - 4 = 0 ⇒ x = 4
However x > 0 ⇒ x = 4 ⇒ b = 4 CM
Answer:
7.5
Step-by-step explanation:
2x+12=6x-18
2x=6x-30
-4x=-30
x=7.5
Answer:
<h2><em><u>x = 4</u></em></h2>
Explanation:
10 + 6x + 2x - 7 = 35
- Add Similar Elements: 6x + 2x = 8x
10 + 8x - 7 = 35
8x + 10 - 7 = 35
8x + 3 = 35
- Subtract 3 From Both Sides
8x + 3 - 3 = 35 - 3
8x = 32
8x / 8 = 32 / 8
<h2><u><em>x = 4</em></u></h2>
Assuming 22 degrees
complement means they add to 90 degrees
22+?=90
minus 22 both sides
?=68
answer would be C
