Answer:
a) (-4, 5)
b) (4, -5)
Step-by-step explanation:
Just reverse the signs or use desmos as a better example.
This problem can be solved using two equations:
The first represents the total trip, which is the miles driven in the morning added to those in the afternoon. Let's call the hours driven in the morning X and the hours driven in the afternoon Y. We get: X + Y = 248.
The second equation relates the miles driven in the morning compared to the afternoon. Since 70 fewer miles were driven in the morning than the afternoon, then X = Y - 70.
Now substitute the equation for morning hours (equation 2) into the total miles equation (equation 1). We get:
(Y - 70) + Y = 248
2Y - 70 = 248
2Y = 318
Y = 159
We know that Winston drove 159 miles in the afternoon.
To find the morning hours, just substitute 159 into the equation for morning hours (equation 2)
X = 159 - 70
X = 89
We now know that Winston drove 89 miles in the morning.
We can check our work by plugging both distances into the total distance equation: 89 + 159 = 248

divide both the numerator and denominator by 8
Answer:
<h2>B</h2>
Step-by-step explanation:
<em>The answer is "B" because the line is passing through the "origin" of the graph, this means that it is intersecting both the y and x axis in a proportional relationship, which is what we need.</em>

Answer:
<u>It is assumed the question is asking to simplify or factorize:</u>
- (a + b)² - a² + b² =
- a² + 2ab + b² - a² + b² =
- 2b² + 2ab
This is simplified expression.
<u>Factorizing as follows:</u>
