4(x+2)=3(x-2)
Multiply the first bracket by 4
Multiply the second bracket by 3
4x+8=3x-6
Move 3x to the left hand side, whenever moving a number with a letter the sign changes ( positive 3x to negative 3x)
4x-3x+8=3x-3x-6
x+8=-6
Move positive 8 to the right hand side
x+8-8=-6-8
x=-14
Check answer by using substitution method
Use x=-14 into both of the equations
4(-14+2)=3(-14-2)
-56+8=-42-6
-48=-48
Answer is -14- D)
Answe Step-by-step explanation:
46579765+4879+889 78+6565
Answer:
6
Step-by-step explanation:
Use the slope formula:
Picking x = 2 and x = 4 as my two points (since the interval is 2 ≤ x ≤ 4), we get:
So, the BEST estimate of the average rate of change for the function given in the table is 6.
That is equal to 70 - 8 x 6
Answer:
54
Step-by-step explanation:
144 divided by 8 is 18
so that means that their hourly rate 18 pizzas per hour
so multiply 18 by 3 and get 54
