Answer:
(–19, 55)
Step-by-step explanation:
y = –3x – 2 equation 1
5x + 2y = 15 equation 2
using equation 1 in equation 2 we have:
5x + 2(–3x – 2) = 15
5x –6x – 4 = 15
-x = 15+4
x=-19
using equation 1:
y = -3(-19)- 2
y= 57-2
y= 55
Answer:
y= - 1/6x -1
Step-by-step explanation:
Given:
Perpendicular line has slope of reciprocal opposite to the given: - 1/6, so the equation:
Finding b using the intersected point:
- -2= -1/6*6 +b
- b= -2 +1= -1
So the equation is:
Answer:
The box can hold 4 1/8 cubic feet of dirt
Step-by-step explanation:
What we simply have to find here is the volume of dirt it can take
To get this, we have to multiply the dimensions of the box
We have this as follows
Volume or box = length * width * height
Volume of box = 2 3/4 * 1/2 * 3
Volume of box = 11/4 * 3 * 1/2 = 33/8 = 4 1/8 cubic feet
5x5x4x7x6 is equal to 4,200
