Answer:

15y² - 11y

Step-by-step explanation:

We have to combine like terms in the given expression :

(7y² - 3y) + (8y² - 8y)

Here second degree term y² and y are the like terms.

So by combining these terms we can solve this.

(7y² + 8y²) - (3y + 8y)

= 15y² - 11y

Therefore, answer is 15y² - 11y

The like terms are: 7y^2 and 8y^2 -3y and -8y. Add them. 7y^2 + 8y^2 = 15y^2 -3x + (-8y) = -3y - 8y = -11y So the answer would be 15y^2 - 11y

What are the zeros of the function f(x)=x2−5x−24 ?

scZoUnD [109]

Factor the equation:
$x^{2} -5x-24 = (x+3)(x-8)$

set each part of the factorized equation to zero and solve for x the results are your zeros:
x+3 = 0
x = -3

x-8 = 0
x = 8

In a seventh grade class, 14 out of 30 students are boys. In simplest terms, what is the ratio of the number of boys to the numb

Triss [41]

${Hello,\;There!}$

They already give you the number of boys {14}, so all you need to do is subtract 30 - 14 which will give you the ratio of girls.

It does this because 14 takes up $\frac{14}{30}$ of the seventh grade class.

$\text{30 - 14 = 16}$

So your answer is going to be 14:16 un-simplified.

However, since they ask you to put it in the simplest terms, we are going to simplify $\frac{14}{16}.$

You can do this by dividing both numbers by 2.

= $\frac{14 \div 2}{16 \div 2}=\frac{7}{8}$

$\bold{So\;your\;answer\;is\;going\;to\;be}$

$= \frac{7}{8}$ or $\text{7:8}$

$\rule{300}{1.0}$

A ball is thrown in the air from the top of a building. Its height, in meters above ground, as a function of time, in seconds, i

Cerrena [4.2K]

Answer:

a.2s b.43.6m

Step-by-step explanation:

h(t)=−4.9t2+19.6t+24

24m = inittial possition

-4.9 t2= -1/2 g t2

19.6t= Vo t

as the initial velocity is positive, the ball is thrown up.

the maximum height of the ball is reached when the velocity is 0

V= Vo-gt=19.6m/s-9.8m/s2 t=0

t=19.6/9.8=2s

<u>it takes 2seconds for the ball to reach its maximum height</u>

h(t)=−4.9t2+19.6t+24

h(2)=-19.6m+39.2m+24=43.6m

<u>the maximum height of the ball is 43.6m</u>
