Answer:
x=-12
x=10
x=-8
x=-5
Step-by-step explanation:
1/4 of 2 1/2 is equal to 1/4 * 2 1/2 which equals 5/8. She gave 5/8 pounds of blueberries to her students on Monday.
2 1/2 - 5/8 = 1 7/8, so she had 1 7/8 pounds of blueberries left.
1/3 of 1 7/8 is 5/8 so she ate 5/8 pound of blueberries out of the 1 7/8 left.
Mrs. O gave the same amount of blueberries on Monday and ate the same amount of blueberries on Tuesday. (5/8 = 5/8)
The scale factor of the two triangles is 3.
<h3>What is Scale Factor?</h3>
Scale factor is a number by which the size of any geometrical figure or shape can be changed with respect to its original size.
Here, Two triangles have angles with the same degrees or Similar triangles.
Scale factor = Base of bigger triangle / base of smaller triangle
= 21 / 7
= 3
Thus, the scale factor of the two triangles is 3.

Slope Formula:
Slope-Intercept Form: y = mx + b
Step-by-step explanation:
<u>Step 1: Define</u>
Point (-2, -4)
Point (2, 0)
<u>Step 2: Find slope </u><em><u>m</u></em>
- Substitute:
- Add:
- Divide:
<u>Step 3: Find y-intercept </u><em><u>b</u></em>
- Substitute in <em>m</em>: y = x + b
- Substitute in point: 0 = 2 + b
- Isolate <em>b</em>: -2 = b
- Rewrite: b = -2
<u>Step 4: Write linear equation</u>
Slope-Intercept Form: y = x - 2
And we have our final answer!
