For the first Listing Exercise:
(NOT A)
1. 5x + 65 = 5(x + 13) because if you apply distributive property to the one from List B, it would equal the same as List A's answer.
2. 5(x + 1) = 5x + 5 because if you apply distributive property to the equation from List A, it would equal the same as the one from List B.
3. 1 + 5x = 5x + 1 because this is simple commutative property.. switching the placements.
state the y-intercept and the slope of the following linear equations.
Answer:
think of y=mx+b
m is the slope
b is the y-intercept
1) y=3/4x-2
slope= 3/4
y-intercept= -2
2) y= -x+3
slope= -x
y-intercept= 3
3) y=3x+5
slope=3
y-intercept=5
4) y=1/2x-5
slope= 1/2
y-intercept= -5
5) y= -2x-4
slope= -2
y-intercept= -4
6) y= -1/5x-1
slope= -1/5
y-intercept= -1
7) y=3/2x+4
slope=3/2
y-intercept=4
8) y=x+1
slope=x
y-intercept=1
9) y=2x+5
slope=2
y-intercept=5
10) y=8/5x+3
slope=8/5
y-intercept=3
11) y= -3x-4
slope= -3
y-intercept= -4
12) y= -2x-2
slope= -2
y-intercept= -2
Answer: FALSE
Step-by-step explanation: This is called balance delay.
Answer:
Step-by-step explanation:
16 = 2 *2 * 2 * 2 = 2⁴
16y⁴ = (2y)⁴
x⁴ - 16y⁴ = x⁴ - (2y)⁴
= (x²)² - [ (2y)² ]²
{Use identity = a² -b² =(a +b)(a- b). Here a =x² & b =(2y)²}
= (x² + (2y)² ) (x² - (2y)² )
= (x² + 4y²) (x² - 4y²)
Answer:
It's a horizontal line passing through 4 on the y-axis.
Simply place a ruler at 4 and draw a straight line from left to right, which passing through the number 4.
