Answer:
The question = (7^3)*(7^x)
When multiplying two exponents with the same base, all you do is add the exponents together and keep the same base
Therefore,
(7^3)*(7^x) = 7^(3+x)
Step-by-step explanation:
7^3+x is the answer
Answer:

Step-by-step explanation:
x² + 5x + 3 = 0
x = (- 5 +/- √5² - 4x1x3)/2x1
= (-5+/-√13)/2
x₁ = (- 5 + √13)/2
x² = (- 5 - √13)/2
Answer:
1. y=3x-2
2. y=-1/4x+5
These equations are in slope-intercept form (y=mx+b). IN this equation m represents the slope and b represents the y intercept. Therefore, y=3x-2 and y=-1/4x+5 are correct

Answer:
4.5 miles
Step-by-step explanation:
2 times as far as last week
last week was 2.25 miles
2* 2.25 = 4.5 miles
