Answer:
1. 8
2. 4
3a. -6 and -4
3b. -1/2 and -5
Step-by-step explanation:
3a explanation:
Factor x^2+10x+24
(x+4)(x+6)
Set the factors equal to 0
x + 4 = 0
x + 6 = 0
-4 and -6
3b.
Factor left side of equation.
(2x+1)(x+5)=0
Set factors equal to 0.
2x + 1 = 0 or
x + 5 = 0
x = −1/2
x = -5
-5 and -1/2
It’s -360 hope that helped
Answer:
Step-by-step explanation:
<u>Given line:</u>
<u>Convert the equation into slope-intercept form:</u>
- x - 4y = 20
- 4y = x - 20
- y = 1/4x - 5
It has a slope of 1/4.
Parallel lines have equal slopes.
<u>Find the parallel line lines that passes through the point (2, - 5):</u>
<u>Substitute x and y values to work out the value of b:</u>
- - 5 = 1/4*2 + b
- - 5 = 1/2 + b
- b = - 5 - 1/2
- b = - 11/2
<u>The line is:</u>
<u>Covert this into standard form:</u>
- y = 1/4x - 11/2
- 4y = x - 22
- x - 4y = 22
