Answer:

(4) 25

Step-by-step explanation:

First, find the slope using rise over run:

(y2 - y1) / (x2 - x1)

Plug in the points:

(11 - 5) / (3 - 0)

6 / 3

= 2

The y intercept, (0, 5), has already been given. Using the equation y = mx + b, plug in the slope and y intercept to create the equation:

y = mx + b

y = 2x + 5

Now, plug in 10 as x to find the value of y:

y = 2x + 5

y = 2(10) + 5

y = 20 + 5

y = 25

So, the correct answer is answer choice 4, 25.

The height of a ball above the ground as a function of time is given by the function h(t)=−32t2+8t+3 where h is the height of th

gavmur [86]

Answer:

0.125 seconds.

Step-by-step explanation:

We have been given that the height of a ball above the ground as a function of time is given by the function $h(t)=-32t^2+8t+3$ , where h is the height of the ball in feet and t is the time in seconds.

We can see that our given equation is a downward opening parabola as its leading coefficient is negative. The maximum point will be vertex of parabola.

To find the time, when the ball would be at its maximum height, we need to find the x-coordinate of vertex.

Using formula $\frac{-b}{2a}$ , we will find the x-coordinate of vertex of parabola as:

$\frac{-b}{2a}$

$\frac{-8}{2*-32}$

$\frac{-8}{-64}$

$\frac{1}{8}$

$0.125$

Therefore, the ball will be at a maximum height after 0.125 seconds.

Answer:

$\huge{ \fbox{ \sf{ - 2y - 30}}}$

Step-by-step explanation:

$\star{ \sf{ \: (4y - 10) - (6y + 20)}}$

$\text{Step \: 1 }\: : \sf{While \: subtracting \: sign \: of \: each \: term \: of \: the \: second \: expression \: changes}$

$\hookrightarrow{ \sf{4y - 10 - 6y - 20}}$

$\text{Step \: 2 \: : \sf Collect \: like \: terms}$

$\sf{Like \: terms \: are \: those \: which \: have \: the \: same \: base.}$

$\hookrightarrow{ \sf{4y - 6y - 10 - 20}}$

$\hookrightarrow{ \sf{ - 2y - 10 - 20}}$

$\text{Step \: 3 \: : \sf{Calculate}}$

$\underline{ \text{Remember!}} : \sf{The \: negative \: integers \: are \:always \: added \: but \: posses \: the \: negative \: ( - ) \: sign.}$

$\hookrightarrow{ \sf{ - 2y - 30}}$

Hope I helped!

Best regards! :D

Write a compound inequality that each graph could represent for the following questions.

ivanzaharov [21]

Answer:

Part 67) $x > -2$ and $x < 3$

Part 68) $x\leq -1$ or $x\geq 1$

Step-by-step explanation:

Part 67) we know that

The solution of the number line is the interval -------> (-2,3)

All real numbers greater than -2 and less than 3

so

The compound inequality could be

$x > -2$ and $x < 3$

"And” indicates that, both statements must be true at the same time

Part 68) we know that

The solution of the number line is the interval (-∞,-1] ∪ [1,∞)

All real numbers less than or equal to -1 or all real numbers greater than or equal to 1

The compound inequality could be

$x\leq -1$ or $x\geq 1$

"Or” indicates that, as long as either statement is true, the entire compound sentence is true
