Determine the percent of change? original: 50 new: 150.

Reptile [31]

Hi there! The percentage of change is 200%

We can find the percentage of change using the following formula:
$\frac{new-original}{original} \times 100$

When we fill in this formula, we get the following:
$\frac{150-50}{50} \times 100 = \frac{100}{50} \times 100 = 2 \times 100 = 200$

Therefore, the percentage of change is 200%

What is the approximate volume of the sphere?

muminat

Your best bet is A. 524

Use the formula V=4/3(pi)r^3 or $v = \frac{4}{3} \pi r ^{3}$

Not sure if that made sense but you need to multiply to radius(cubed) by pi and divide it by 4/3

Next time just google the volume formula of a sphere

The two ys must be the same. Equate the two right hand sides.

-x + 10 = x + 2 add x to both sides.
10 = x + x + 2
10 = 2x + 2 Subtract 2 from both sides.
8 = 2x Divide by 2
x = 8/2
x = 4

Now solve for y
y = x + 2
y = 4 + 2
y = 6

Use the other equation to check it.

y = - x + 10
y = -4 + 10
y = 6

Two linear functions are displayed. Function One is represented by the graph:

GarryVolchara [31]

Answer:

Option A

Step-by-step explanation:

Function One is represented by the graph. We can see that the slope of the First Function is positive because the formula of slope is

$Slope=\frac{Change\ in\ y}{Change\ in\ x} \\\\$

And we can see that in the graph the change in y and change in x are both positive as the function is increasing because if we see the graph closely,

When x = 1 the value of y = 2 and when x = 2 the value of y = 4 and when x = 3 the value of y = 6 so the values are increasing of x and of y hence the slope is positive and the value of slope is 2.

Now the Second Function which is y = -4x here the slope is negative because the slope-intercept form of the equation is .

$y=mx+b$

and the second function is

$y=-4x$

if we compare both these equations we get the value of m = -4 where m is also called the slope. So the slope of the second function is negative.

Option B is incorrect because the slope of the first function is positive

Option C is incorrect because the slope of the second function is negative

Option D is incorrect because the slope of the first function is 2 and the slope of the second function is -4

That leaves us with Option A which is correct, where we can see that the slope of the first function is positive and the slope of the second function is negative
