I think it would take 24 hours or 10 hours
explanation: if you have 4 hours from Erin, and 6 hours from Cathy, it’ll most likely be 10 hours because you’re trying to find out the total amount. (keyword: together & how many)
Just multiply then add them and if the answer is to big then add and if it is to small sorry not that good at math but I️ try
Answer:
B
Step-by-step explanation:
using quadratic equation
Y =2x +14
-4x –y = 4 so y = -4x – 4
2x + 14 = -4x – 4
2x + 4x = -4 - 14
6x = -18
x = -18/6
x = -3
Y =2x +14
y = 2(-3) +14
y= -6 +14
y=8
answer:
y-coordinate is 8
Answer:
Slope = -2
Y intercept = 4
Equation. y = -2x +5
Step-by-step explanation:
Using points, (1,2) and (3,-2)
Slope = (-2-2)/(3-1) = -4/2 = -2
Y intercept = 4
-2 = (y-3)/(x-1)
-2(x-1) = y-3
-2x +2 = y-3
y = -2x +2 +3
y = -2x +5
