C) It doesn’t satisfy either the top or bottom equations.
When we plug them into the top equation:
Simplify:
Because the statement of -23 = -15 is wrong, the solution pair is wrong for the top equation.
When we plug them into the bottom equation:
Simplify:
9 = -8 is not a valid statement, so the pair doesn't satisfy both of the equations.
Answer:
1. m=- -1 2. -1+1
Step-by-step explanation:
Ok for the first one you need to label 3 x1 0 y1 6 x2
and -3 y2
Next you need to do y2-y1 over x2-x1 so fill that in and your equasion is (-3-0)
------------ = -3
( 6-3) ----
3
That reduces to -1 because -3 divided by 3 is -1
As for number 2 we need to find b to do this pick any of the y's from before we can go with 0 so the 0 is y in the equasion and we already learned slope is -1 so your equasion should be 0=--1+b ok to solve this you need to add -1 to both sides since its a negitive so you add 1 to 0 which is 1 and when you add 1 to -1 it cancells it out so you have 1=b so b is 1 for the equsion you just fill it in so it is y=- -1+1

The formula is
A=p (1+rt)
A future value 2408
P present value 1400
R interest rate?
T time 12 years
Solve the formula for r
R= ((A/p)-1)÷t
R=((2,408÷1,400)−1)÷12
R=0.06×100
R=6%
Answer:
Step-by-step explanation:
<u>The volume is:</u>
- V = Bh, where B- area of base, h - height
<u>Find the area of base, which is the trapezoid:</u>
- B = 1/2*(5 + 7.5)*6 = 37.5 in²
<u>Find the volume:</u>
Answer:
1.125
Step-by-step explanation:
the unit cost is how much it cost per wheel
dozen is 12
so 12 times 6 is 72
so then you do 81/72 to get your answer
and you are probably wondering how i got the divison from was because i'm supposed to divide to find a unit cost.
the 81 was the total for the 72 packages of toy wheels
