Answer:
x = 15
Step-by-step explanation:
Assuming you require the value of x
The product of the external part and the whole of one secant is equal to the external part and the whole of the other secant, that is
9(9 + x) = 8(8 + 19), that is
81 + 9x = 8 × 27 = 216 ( subtract 81 from both sides )
9x = 135 ( divide both sides by 9 )
x = 15
TLDR: 1 is 3, 2 is 5, 3 is 8.
Luckily for you, question 1 and 2 are linear functions. You don’t have to do any extra calculations to find the rate of change, because it’s always consistent. Question 1 is 3, and question 2 is 5.
Question 3 involves the evaluation of a quadratic, so we have to do a little bit of math. Plug in the two endpoints of the interval into the equation to obtain their y-coordinate values; we’ll use these points to calculate the slope.
(1,3) and (3, 19)
Now, using the slope formula:
M=y2-y1 = 19-3 = 16=8
x2-x1 3-1 2
The slope for Question 3 is 8.
