Part 5 ASAP math ofc

First equation solution:

x≤4

Second equation solution:

x≥4

Step-by-step explanation:

1/2x+8≤ 10

subtract 8 from each side

1/2x≤ 2

multiply each side by 2

x≤ 4

-3x-24≤- 36

add 24 to each side

-3x≤ -12

divide by -3 ( when dividing or multiplying by a negative number the </>/≤/≥ flips)

x≥4

answer: answer is b.

[m < b = 120º]

step-by-step explanation:

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
