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.

Pleas help me answer this. Question 2 please.
tamaranim1 [39]

Answer: A

We could solve it but it's easier to just check the given solutions.

A. (7,1)

2y + 5 = 2(1)+5 = 7 = x, good

x/3-y = 7/3 - 1 = 4/3, good

B. (-3,8)

2y + 5 = 2(8)+5 = 21 not x=-3, doesn't check

C. Can't be true because we found a solution

D.  Infinitely many solutions not true because the lines have different slopes

Stephen evaluated (6.34 x 10^-7)(4.5 x 10^3). His work is shown below. Which statements describe his errors? Check all that appl
Lostsunrise [7]
We have the following expression:
 (6.34 x 10 ^ -7) (4.5 x 10 ^ 3)
 The solution shown is:
 (6.34 x 10 ^ -7) (4.5 x 10 ^ 3)
 (6.34 x 4.5) (10 ^ -7 x 10 ^ 3)
 28.53 x 10 ^ -4
 -28.53 x 10 ^ 4
 -2.853 x 10 ^ 3
 The errors are:
 A. He changed the sign of the coefficient. A negative exponent does not affect the sign of a coefficient in scientific notation. The sign of the exponent determines the direction the decimal is moved in.
 D. He got the wrong value for the coefficients; 28.53 x 10^-4 is not possible. The coefficients in scientific notation are always greater than 1, but less than 10.
