Answer:
f(-1)=8
Step-by-step explanation:
Just plug in x=-1 into the function:
f(x)=6-2x
y=6-2(-1)
y=6+2
y=8
So f(-1)=8
Try 4 because a die has six sides and 6-2=4
How ever many numbers are being multiplied by itself it goes with the to the power of ... if it is being added to itself it is ... times...
When there is a midpoint in a line segment, the two segments that are then produced have to be equal. So that means that because E is a midpoint of DF, DE=EF.
Set up the equation.
DE=EF
2x+4=3x+1
Then solve for x.
x=3
Then plug it back in the equation to find DE and EF.
DE=2x+4=2(3)+4=10
Because DE=EF then EF is also 10.
DF is made from the addition of DE and EF so DF is twice EF.
DF= 20
DE= 10, EF= 10, DF= 20
Hope this helps.
The number 5 is a rational number, so you must be able to express it as a quotient, and you can. Dividing any number by 1 gives you the original number, so to express an integer like 5 as a quotient, you simply write 5/1. The same is true for negative numbers: -5 = -5/1
