3 Eva is running for class president. She creates a sign in the shape of an isosceles triangle to
hang in the cafeteria. If the base of the triangle
is 36 inches, which of the following is true
about the other sides?
A One side measures 24 inches and the other
20 inches,
B The other sides must each measure
36 inches.
C The other sides must be equivalent and
each measure greater than 18 inches.
D The other sides must be equivalent and
each measure less than 15 inches.

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
