Answer:

A, E, slope of 6
B, F, slope of 1/4
C, D, slope of 2/5

Step-by-step explanation:

Each triangle represents a triangle that could be used to compute the slope of a line. That slope is the ratio of the vertical measure to the horizontal measure. For each of the triangles shown, the associated slopes are ...

A: 54/9 = 6

B: 15/60 = 1/4

C: 18/45 = 2/5

D: 16/40 = 2/5

E: 72/12 = 6

F: 13/52 = 1/4

Then the boxes on each horizontal line can be filled with ...

A: (E, 6)

B: (F, 1/4)

C: (D, 2/5)

Gianna is going to throw a ball from the top floor of her middle school. When she throws the hall from 48 feet above the ground,

vazorg [7]

Answer:

So, the times the ball will be 48 feet above the ground are t = 0 and t = 2.

Step-by-step explanation:

The height h of the ball is modeled by the following equation

$h(t)=-16t^2+32t+48$

The problem want you to find the times the ball will be 48 feet above the ground.

It is going to be when:

$h(t) = 48$

$h(t)=-16t^{2}+32t+48$

$48=-16t^{2}+32t+48$

$0=-16t^{2}+32t+48 - 48$

$16t^{2} - 32t = 0$

We can simplify by 16t. So

$16t(t-2)= 0$

It means that

16t = 0

t = 0

t - 2 = 0

t = 2

So, the times the ball will be 48 feet above the ground are t = 0 and t = 2.

The difference between two numbers is 15. If 8 is added to twice the greater number, the result is 4 less than 3 times the lesse

yuradex [85]

Answer:

Step-by-step explanation:

Let $x$ be the greater number and $y$ be the smaller number. We know that their difference is 15, so we have

$x-y=15$

Then, we have the following information: if we add twice the greater (2x) and 8 (2x+8), the result is 3 times the lesser (3y) minus four (3y-4). So, we have

$2x+8 = 3y-4 \iff 2x-3y = -12$
