We can focus on each part separately, first the numbers:
-3 times (5 squared)
-3 times 25
= -75
This rules out the last two options
Next let’s focus on the x terms:
x^3 times (x^5 squared)
When raising a term that is already raised to a power by another power, you multiply the powers, in this case 5 times 2 = 10
x^3 times x^10
When multiplying numbers with the same base, you add the powers
=x^13
So the answer must be B but we can check the y terms just to make sure
y^2 times (y^4 squared)
y^2 times y^8
=y^10 which matches answer B
Step-by-step explanation:
x=-2+y
7(-2+y)+2y=-5
-14+7y+2y=-5
9y=9
y=1
x=-2+1
x=-1
Gross pay is before taxes are taken out...
11.25(40) = 450 <== gross weekly pay
Point A is at -11. The half way point from there to 0 is -5.5.
6.7-2.3= 4.4 is the answer to the problem
