12 because the 23 3/8 is rounded down and the 11 2/9 is rounded down as well
Answer:
what do u want me to do
Step-by-step explanation:
Answer:
y=4x+7
Step-by-step
(-2,1) and (1,-11)
1)Rule you should use is run over rise aka slope
y²-y^1=
x^2-x^1=
(-11)-1=12
1-(-2)=3
12/3=4
slope =4
2)Rule of point slope intercept
y - y1 = m(x - x1)
y+1=4(x+2)
y+1=4x+8
-1 -1
y=4x+7
X+7= Yvonne's age.
a. 4(x+7)=200
b. 4(x+7)=200
4x+28=200
4x=172
x=43
Yvonne is 43 years old.
c. 43-7=Xavier's age.
36
Xavier is 36 years old.
