Step-by-step explanation:
Imagine 8 pieces of fruit and 2 bars are arranged in a line such that the 2 bars split the rest of the fruits into 3 portions.
Hence the number of ways = 10C2 = 45.
Slope of y=1-2x is -2
Using point intercept form:
y-1=-2(x-3)
y-1=-2x+6
y=-2x+7
Y+7
Y is the variable and 7 is the constant.

4x² - 5 = 75
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Addition Property of Equality] Add 5 on both sides: 4x² = 80
- [Division Property of Equality] Divide 4 on both sides: x² = 20
- [Equality Property] Square root both sides: x = ±2√5
