Answer: -6.25
Step-by-step explanation: 0.5 -3(0.5+1)^2
=0.5 -3(1.5)^2
= 0.5 -3(2.25)
= 0.5-6.75
= -6.25
Answer:
False
Step-by-step explanation:
Substitute x and y with the numbers in the coordinate pair.
Just as a recap-
3 is the x value
7 is the y value
2(3) + 2(7) = 20
20 < 20
This is not true since 20 = 20
Hence, the answer is false
C-b=6
solve for c
c=b+6
substitute b+6 for c
b+c=10
b+(b+6)=10
2b=4
b=2
substitute that in to find C
c-b=6
c-2=6
c=8
a+b+c=18
a+2+8=18
a+10=18
a=8
so a=8, b=2, c=8
