Answer: x=−23

Step-by-step explanation:

Let's solve your equation step-by-step.

x+8=−15

Step 1: Subtract 8 from both sides.

x+8−8=−15−8

x=−23

Your Answer is C (25,25).

On the second tringle there is x+20

On the first there is 5x

This means the second triangle is 5+20=25

So both are 25

Hope this helps!

Kyle notices that the number of likes he receives each day on his social media page is a function. He decides to create a graph

nadya68 [22]

Answer:

D) 360

Step-by-step explanation:

The data Kyle collected is (0, 0), (1, 12), and (2, 24), where x represents days and y represents likes.

We can write a linear function to model this situation.

This will be of the form

$y = mx$

because it passes through the origin , where m is the slope.

The slope is

$m = \frac{12 - 0}{1 - 0} = 12$

Hence the equation is

$y = 12x$

To find the number of likes on the 30th day, we put x=30 into the equation to get:

$y = 12 \times 30 = 360$

The correct choice is D

lisabon 2012 [21]

Answer:

The first listed equation is the correct equation to solve

The correct answer is: t = 5 seconds

Step-by-step explanation:

Let me mention first that there is an error in the statement that the gravitational pull of the Earth is 16 ft/s^2. It is in fact 32 ft/s^2, and the actual equation uses half of the acceleration multiplied by the square of the variable time, so it gives as final expression :

$y(t)=-16\,t^2+ 0 \,t +400$

and we want to find the value/s for "t" that make this equation equal zero (when it reaches the ground and the object just touches the ground. This makes the equation we want to solve:

$0=-16\,t^2+ 0 \,t +400\\16\,t^2+0\,t -400=0$

which solving for "t" becomes:

$16\,t^2-400 =0\\16\,t^2=400\\t^2=\frac{400}{16} \\t^2=25\\t= +/- 5\,\,sec$

So we adopt the positive answer (positive time) since the negative value has no physical meaning for this problem.

That is: t = 5 seconds
