Answer:
0.1 miles per minute
Step-by-step explanation:
The line goes through (0, 0), so Maria's speed is the ratio of miles to minutes:
(4.5 mi)/(45 min) = 0.1 mi/min
Answer:
Part 1) The exact solutions are
and
Part 2) (1.79, 8.58)
Step-by-step explanation:
we have
----> equation A
----> equation B
we know that
When solving the system of equations by graphing, the solution of the system is the intersection points both graphs
<em>Find the exact solutions of the system</em>
equate equation A and equation B
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
so
substitute in the formula
so

Answer:
x = - 45
Step-by-step explanation:
x+23(-23)=−22 (-23)First subtract 23 from both sides
x = - 45
Answer:
g(-7) = 5
Step-by-step explanation:
Step 1: Define
g(x) = -2x - 9
g(-7) is x = -7
Step 2: Substitute and Evaluate
g(-7) = -2(-7) - 9
g(-7) = 14 - 9
g(-7) = 5
