Answer:
This is not possible because the selling of number of AA batteries cannot be negative.
Step-by-step explanation:
Let us assume that the number of AAA batteries sells be x .
Let us assume that the number of AA batteries sells be y.
As given
Target sells AAA batteries for $1.10 and AA batteries for $0.50. They sold 350 total batteries earning a total of $560.
Equations becomes
x + y = 350
1.10x + 0.50y = 560
Simplify the above equation
110x + 50y = 56000
Two equations becomes
x + y = 350
110x + 50y = 56000
Multiply x + y = 350 by 50 and subtracted from 110x + 50y = 56000 .
110x - 50x + 50y - 50y = 56000 - 17500
60x = 38500
x = 641 .6 (Approx)
Put this value in the equation x + y = 350 .
641.6 + y = 350
y = 350 - 641.6
y = -291.6
This is not possible because the selling of number of AA batteries cannot be negative.
Answer:
4
-20
-12
Step-by-step explanation:
g(4)
= 4(4)-12
= 16-12
= 4
g(-2)
=4(-2)-12
=-8-12
=-20
g(0)
=4(0)-12
=0-12
=-12
First step is to find R
use The equation QR =43
R=43/Q
now since we have R plug that into PR= 9x - 31
P(43\Q) = 9x - 31
P43/QP +31 =9x
9x=P43÷QP +31
x=P43÷QP+31 /9
Since the question doesnt specify to leave the question in terms of P or Q i suppose this is the final answer
Hope this helps! xD
would not mind if you put it as the brainliest answer
Answer:
The perpendicular equation is y = -3x -21
Step-by-step explanation:
Perpendicular lines have the exact opposite slope as the other equation and they never have the same y-intercept.
To find the perpendicular slope just look at the slope in the original equation and get the exact opposite.
First let's simplify the equation.
-5 + x = 3y (divide by 3 on both sides to get y by itself)
-5/3 + 1/3x = y or y = 1/3x + 5/3
The exact opposite of this slope would be -3.
Now plug in the point you were given so that we can find the y-intercept.
6 = -3(-9) + b (b = y-intercept)
6 = 27 + b (subtract 27 on both sides)
-21 = b
So the perpendicular equation looks like this.
y = -3x -21
