It is linear because both variables have an exponent of 1. (FYI: one of the exponents can be 0 and still be a linear equation).
2x + y = 8
<u>-2x </u> <u> -2x</u>
y = -2x + 8 ⇒ slope (m) = -2 and y-intercept (b) = 8
plot the y-intercept (0, 8). then plot the next point by counting the rise over run from the y-intercept. <em>count 2 units down and 1 unit to the right </em>= (1, 6).
If you're talking about the red shaded part, the answer is 8
Answer:
Slope is -3
The x intercept is (0,-1)
The intercept is (- 1/3, 0)
Distance biked before lunch = 1
km (the number is written in mixed fraction)
⇒ Distance biked before lunch = 
Distance biked after lunch = 6
km (the number is written in mixed fraction)
⇒ Distance biked after lunch = 
We need to determine how much farther does Hallie bike after lunch than before lunch
Extra distance biked after lunch vs. before lunch = -
⇒ Extra distance biked after lunch vs. before lunch = 
⇒ Extra distance biked after lunch vs. before lunch = 
⇒ Extra distance biked after lunch vs. before lunch = 4 (in mixed fraction)
Hence, Hallie biked 4 km extra after lunch vs. before lunch.
Answer:
<h3>6 days</h3>
Step-by-step explanation:
Given the inequality expression of the total cost (c) in dollars of renting a car for n days as c ≥ 125 + 50n
To get the maximum number of days for which a car could be rented if the total cost was $425, substitute c = 425 into the expression and find n
425 ≥ 125 + 50n
Subtract 125 from both sides
425 - 125 ≥ 125 + 50n - 125
300≥ 50n
Divide both sides by 50
300/50≥50n/50
6 ≥n
Rearrange
n≤6
<em>Hence the maximum number of days for which a car could be rented if the total cost was $425 is 6days</em>
