I believe anything that is squared (^2) is a quadratic. so a, b, e and f are quadratics. you could also check on desmos to see if they are parabolas (u shape).

Corbin can shoot 24 baskets In 3 minutes. Which table best represents this relationship?

seraphim [82]

Answer:

Table C

Step-by-step explanation:

This is the proportional relationship:

y = kx

We have x = 3, y = 24, then k is:

24 = 3k
k = 8

The table will look as:

x = 1 ⇒ y = 1*8 = 8
x = 2 ⇒ y = 2*8 = 16
x = 5 ⇒ y = 5*8 = 40

Correct choice is C

anastassius [24]

Answer:

Value of y = 7

Step-by-step explanation:

By the midpoint theorem of the triangles,

"Segment joining midpoints of the two sides of a triangle is parallel to the third side and measure half the length of the third side."

Therefore, from the figure attached,

In ΔFGH,

J and K are the mid points of the two sides GH and FH.

By theorem, segment JK║GF and m(JK) = $\frac{1}{2}m(FG)$

$(2y+5)=\frac{1}{2}(5y+3)$

(5y + 3) = 2(2y + 5)

5y + 3 = 4y + 10

5y - 4y = 10 - 3

y = 7

What is 4 over 10 plus 88 over 100

denpristay [2]

Answer:

1.28

Step-by-step explanation:

4/10 + 88/100

so this is unlike denominators so

4 times 10 and 10 times 10 equal to 40/100

so 40/100 + 88/100 equal to 128/100 so we simplify 128÷2 and 100÷2 equal to 64/50 and 64÷2 and 50÷2 equals 32/25 we do long division then it is equal to 1.28
