1/2.
divide everything by 9.
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.
Answer:
linear because as x goes up by 1 f(x) goes up by exactly 1.1 for each one !
Step-by-step explanation:
Answer:

Solution,
base=1
perpendicular=?
hypotenuse=X
now,
using Pythagoras theorem,
x^2=p^2+b^2
or, x^2=p^2+1^2
or,p^2=x^2-1
or, p=√x^2-1
tan theta=perpendicular/ base
tan theta =√x^2-1/1
tan theta=√x^2-1
z=tan theta
z=√x^2-1
Hope this helps...
