let x represent granddaughter and x +2 for grandson and together they = 12
so then we have the equation of x+2+x = 12
combine like terms 2x +2 =12
-2 from both sides to isolate x
2x=10 divide both sides by 2 to get x by itself
so we get x = 5 then add 2 +5=7
so grandson is 7 and granddaughter is 5
Do y-y over x-x
So 10-4 = 6 and -7 - 1 = -8
6/-8 = -.75 is your slope
plug it into a y= Mx + b equation along with a y and x pair
4 = -.75(1)+ b
4 = -.75 + b
Solve the equation which gets you to b= 4.75
So y = -.75x+ 4.75 is your answer

Answer:
x = -2
Step-by-step explanation:
You can also solve for the equation given.
2x + 7 = 1 - x
3x = -6
x = -2
Answer:
A) $7,833.32
Step-by-step explanation:
Given data
Principal= $4,571
Rate=3%
n= 6
Time = 18 years
The expression for compound interest is
A=P(1+r/n)^nt
substitute
A= 4571(1+0.03/6)^6*18
A= 4571(1+0.03/6)^6*18
A= 4571(1+0.005)^6*18
A= 4571(1.005)^6*18
A= 4571(1.005)^108
A=4571*1.7136
A=$7832.86
Hence the approximate amount is A) $7,833.32
