The 3 angles need to equal 180

The middle angle is given as 100.

180 -100 = 80

There is an x on each side so you have 2x

2x = 80

X = 80/2

X = 40 degrees

Answer:

Each x should equal 40

Step-by-step explanation:

The total is equal to 180°. You already know that you have 100°. Then if you subtract 100° from 180° you will get 80°. Since you have two “x” you need to divide 80° by two and you’ll get 40°

Find f(2), f(1), f(0), and f(-1) for f(x) = 3x + 8.

cupoosta [38]

Answer:

Step-by-step explanation:

Solution

When, x=2

f(2)=3×2+8

=14

Again,

When, x=1

f(1)=3×1+8

=11

When, x=0

f(0)=3×0+8

When, x=-1

f(-1)= 3×(-1)+8

Brenda has a job offers at two companies. One company offers a starting salary of $75,000 with a raise of $2,500 each year. The

Sedbober [7]

For this case, the first thing we must do is define variables.

We have then:

x: number of years

y: total salary

For company 1 we have:

$y = 2500x + 75000$

For company 2 we have:

$y = 5000x + 55000$

By the time both salaries are equal we have:

$2500x + 75000 = 5000x + 55000$

From here, we clear the value of x.

We have then:

$5000x - 2500x = 75000 - 55000\\2500x = 20000$

$x = \frac{20000}{2500}\\x = 8$

Answer:

Brenda's salary would be the same with both companies in 8 years.
