Answer:
y=-5x-1
Step-by-step explanation:
If parallel lines, then the slope is the same.
y=-5x+b
To solve for b, plug in (-1,4)
(4)=-5(-1)+b
4=5+b
-1=b **Subtract 5 from both sides**
y=-5x-1

Answer:
1.39
Step-by-step explanation:
Given the quadratic equation :
2x^2+3x-8 = 0
We could apply the quadratic equation formula :
a = 2 ; b = 3, c = - 8
The formula is stated as :
-b±sqrt(b² - 4ac)/2a
To save computation tune, we could use a calculator :
The roots are : - 2.886 ; 1.386
The positive solution rounded to the nearest hundredth is : 1.39
144 < 165 < 169
sqrt (144) < sqrt(165) < sqrt (169)
12< sqrt(165) < 13
C) It lies between 12 and 13 on a number line.
Choice C
