Answer:
The answer is
<h2>8 hours</h2>
Step-by-step explanation:
To solve this question we use ratio and proportion
From the question
Lisa drove 819 miles for 13 hours
If for Lisa drove 819 miles for 13 hours
Then for 504 miles she will drive
<h2>
</h2>
We have the final answer as
<h3>8 hours</h3>
Hope this helps you
Answer:
-2c^2 + c
Step-by-step explanation:
Variables: x, y, z (we should multiply them and put them together )
Then coeffitions, we should multiply them
Now put coeffitions before variables:
Y = mx + b
b: y-intercept (when x equals zero)
m: slope ((y₂ - y₁) ÷ (x₂ - x₁))
Y - Intercept:
To find the y-intercept, just look at the table. The y-intercept is whatever y equals when x equals zero. In this case it is -8.
Slope:
(y₂ - y₁) ÷ (x₂ - x₁)
Pick two points and substitute them into this equation. Let's use (-3, 1) and (-2, -2).
(-2 - 1) ÷ (-2 + 3)
-3 ÷ 1
-3
Now substitute these values back into the equation.
y = mx + b
y = -3x - 8
The answer is a.
