Answer:

x = - 3

Step-by-step explanation:

Given the 2 equations

y = \frac{1}{3} x + 7 → (1)

y = 3x + 15 → (2)

Since both equations express y in terms of x, equate the right sides

3x + 15 = \frac{1}{3} x + 7

Subtract \frac{1}{3} x from both sides

\frac{8}{3} x + 15 = 7 ( subtract 15 from both sides )

\frac{8}{3} x = - 8 ( multiply both sides by 3 )

8x = - 24 ( divide both sides by 8 )

x = - 3

Jonathan went to the movies with $48 he earned at his after-school job. The ticket cost $8.75. He spent $7.45 for refreshments.
aleksley [76]

Answer:

8.75+7.45=16.2. 16.2 is equal to $16.20 so 48.00-16.20=31.8. Jonathan had $31.80 left.

Simplify the expression. Write your answer as a complex number.
prohojiy [21]

Answer:

15-8i

Step-by-step explanation:

we know that

The algebraic expression is equal to

5\sqrt{9}-\sqrt{-64}}

Remember that

\sqrt{9}=3

and

i=\sqrt{-1}

so

\sqrt{-64}=i\sqrt{64}=8i

substitute

5\sqrt{9}-\sqrt{-64}}=5(3)-(8i)=15-8i
