a=-9

d=-2-(-9)

= 7

d= 5-(-2)

= 5+2

a24 = a+23d

= -9 + 23×7

= -9 + 161

a24 = 152

so, answer is b.152

hope it will help you.

Step-by-step explanation:

$a_{n}=a_{1} +d(n-1)\\a_{n}=-9 +7(n-1)\\a_{24}=-9 +7(24-1)\\a_{24}=-9 +7(23)\\a_{24}=-9 + (161)\\\\a_{24}=152\\$

One number is 9 more than twice another. If their difference is 22, what is the larger number?

mafiozo [28]

Let, the numbers are: x, y
So, Equations will be: x - y = 22
x = 2y + 9

Substitute the value of x in first equation,
2y + 9 - y = 22
y = 22 - 9
y = 13

x - 13 = 22
x = 22 + 13 = 35

In short, Larger number would be 35

What is the slope of the line that goes through (2, 5) and (-6, -2) ?

alexira [117]

Answer:
slope = 7/8

Explanation:
Slope of the line can be calculated using the following equation:
slope = $\frac{y2 - y1}{x2 - x1}$

The two points given are:
(2,5) representing (x1 , y1)
(-6,-2) representing (x2 , y2)

Substitute with the points in the above equation to get the slope as follows:
slope = $\frac{-2 - 5}{-6 - 2}$ = 7/8

Hope this helps :)
