Answer:
39.25
Step-by-step explanation:
Area of the shaded part= Area of the Square - Area of the Triangle
Area of the Triangle= b*h/2= 2*3/2= 3
Area of the Square= side²= (6.5)²= 42.25
Area of the shaded part= 42.25 - 3= 39.25
I hope this helps you
y=f (x)=x-7
y=x-7
x=y+7
f^-1 (x)=x+7
Answer:
-1/2
Step-by-step explanation:
It's the exact opposite. aka the negative version of the number.
Answer:
h=-15, -15 hours is your answer. You can't work negative hours though which means that Regina and Phil will never be able to make the same amount.
Phil has a higher rate and starting value, this means that Regina will never make the same amount working the same hours.
Step-by-step explanation:
Regina: 6.5h
Phil: 3(2.5h+5)
When you plug in the number of hours, you get the weekly pay. In order to get the same weekly pay, set the equations equal to each other.
6.5h=3(2.5h+5), This is an equation to find the number of hours it will take for them to get equal pay. Now, simplify.
6.5h=7.5h+15
-h=15
h=-15, -15 hours is your answer. You can't work negative hours though which means that Regina and Phil will never be able to make the same amount.
Phil has a higher rate and starting value, this means that Regina will never make the same amount working the same hours.
Answer:
x=3
y=1
Step-by-step explanation:
We know that y is basically two less than x, so we can plug that into the second equation:
x+ (x-2) = 4
We can now simplify:
2x-2=4
2x=6
x=3
After finding x we can now find y with any equation (both work):
y= 3-2
y=1
Hope this helped!
