-7 -14(1/7)
remove parenthesis
14 * 1/7 = 2 (14/1 * 1/7 = 2/1 which we reduce to just 2)
-7 -2
-9
The x- intercept is where y = 0 on the graph and the y- intercept is where x= 0 on the graph. When X=0, all the terms, except for the constant are equal to zero, thus the y- intercept is the constant. y=10 when x=0. Use the quadratic formula to find the x value where y=0.
x= (-b +or- sqrt(b^2 -4ac))/2a
y=ax^2 +bx +c
The answer for the x- int is imaginary. This happens because 10 is the parabola's minimum value and it never touches the x- axis. y-int is 10
Not enough Information. I could say 50 and it would work. I could say 68 and it would work. Any even number thats under 80 but higher than what you think her eldest son is.
(B)Decreasing is the answer
This is how you write 5.24 in expanded form 5+0.2+0.04
