Answer:
1-Two angles are called complementary when their measures add to 90 degrees
EXAMPLES= 30 AND 60 DEGREES ANGLE
40 AND 50 DEGREES ANGLE
80 AND 10 DEGREES ANGLE
2-An acute angle is an angle that measures less than 90 degrees.
EXAMPLES = 40 DEGREE ANGLE
10 DEGREE ANGLE
45 DEGREE ANGLE
For this case we have the following system of equations:
y = x + 5
y = -2x - 1
Substituting the point (-2, 3) we have:
For Line C:
y = x + 5
3 = -2 + 5
3 = 3
The line goes through this point.
For Line D:
y = -2x - 1
3 = -2 (-2) - 1
3 = 4 - 1
3 = 3
The line goes through this point.
Answer:
(-2, 3), because both lines pass through this point

<u>Missing part of the question</u>
Hayley bakes zucchini bread and banana bread. Some ingredients Hayley uses for each type of bread are shown in the tables
Zucchini Bread
2 eggs 2 cups of flour 1.5 cups of sugar 0.5 stick of butter
Banana Bread
1 egg 3 cups of flour 2 cups of sugar 0.25 stick of butter
Answer:
Step-by-step explanation:
Given
Since there are enough of other ingredients, we will only consider the amount of eggs and cups of flour.
So, we have:
Zucchini Bread
Banana Bread
<u>For the eggs</u>
The ratio of eggs to use in the Zucchini bread to Banana bread is:
(z) : (b)
This gives:
The total number of eggs cannot exceed 9.
So, the inequality is:
<u>For the flours</u>
The ratio of flours to use in the Zucchini bread to Banana bread is:
(z) : (b)
This gives:
The total cups of flours cannot exceed 15.
So, the inequality is:
Hence:
The system of inequalities is:
<span>(3 − 4)(2 + 5) = -1 * 7 = -7
hope it helps</span>
