Answer:

x = 81

Steps:

It says that y ~ √x

We have points (9, 18) as a guide.

We can write y = f(x) = a√x +b

Use points (9, 18) as a guide

18 = a√9 +b

18 = 3a + b

One solution might be a = 6, which means f(x) = 6√x

Thus when y = 54,

54 = 6√x

9 = √x

81 = x

yKpoI14uk [10]

So,

If she keeps one-fourth for herself, she will keep:
72 * 0.25 = 18

That leaves the rest for her friends.
72 - 18 = 54

Her friends will get 54 "Suites."

What is the slope of this graph?

pishuonlain [190]

Answer:

Slope = -1

Step-by-step explanation:

Since, slope of a line passing through two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by,

Slope = $\frac{y_2-y_1}{x_2-x_1}$

Therefore, slope of a line passing through two points A(1, 4) and B(3, 2) will be,

Slope = $\frac{4-2}{1-3}$

= (-1)

Therefore, slope of the line is (-1).

WILL GIVE BRAINLIEST 6x-8y=-16 write in slope-intercept form. . . pls step by step or no brainliest

geniusboy [140]

Answer:

it would be y= 3/4x + 2

Step-by-step explanation:

the form is y=mx+b

and you have to set it up as 8y=16-6x

Divide each term

Cancel the common factor of 8.

Divide y by 1

then simplify and turn it into a fraction.

Amanda worked the entire summer before her freshman year of college. She saved $2000. She withdraws $150 per week for expenses.

ivolga24 [154]

Answer:

12 weeks.

Step-by-step explanation:

Amanda starts with $2000 and is getting $150 per week which means that we can make the expression:

$2000-150n=200$

The expression is equal to 200 because is the limit where we can arrive to avoid the fee, then the n is the number of weeks that we are looking for:

$150n=2000-200\\n=\frac{1800}{200}\\n=12$

n=12 weeks
