Answer:

3) 5

5) 1

Step-by-step explanation:

substitute the value of 9 for each 'x' in the expression

3) h(9) = 2/3(9) - 1

= 18/3 - 1

= 6-1 or 5

substitute the value of 5 for each 'x' in the expression

5) f(5) = -5² + 6(5) - 4

= -25 + 30 - 4

= 5-4 or 1

–19w + 11 = –17w − 19<br> w=<br> Please help, will mark brainliest to correct answer!

pychu [463]

Answer:

w = 15

Step-by-step explanation:

We have an expression and are asked to solve for w.

-19w + 11 = -17w - 19

Subtract 11 from both sides :

-19w = -17w - 30

Add 17w to both sides :

-2w = -30

Divide -2 from both sides to isolate w :

w = 15

Nathaniel purchases a one year membership pass to an art museum as a member he receives a discounted entrance fee the total cost

Arturiano [62]

For this case, we must find the equation of the line.
The generic equation of the line is:
$y-yo = m (x-xo)
$
The slope of the line is:
$m = \frac{y2-y1}{x2-x1}$
Substituting values we have:
$m = \frac{15-12}{2-0}$
Rewriting:
$m = \frac{3}{2}$
$m = 1.5$
We now choose an ordered pair:
(xo, yo) = (0, 12)
Substituting values we have:
$y-12 = 1.5 (x-0)$
Rewriting the equation:
$y= 1.5x+12$
For 20 visits, we evaluate the equation when x = 20.
We have then:
$y= 1.5(20)+12$
$y= 30+12$
$y= 42$
Answer:
The discounted entrance fee is 1.5$. The total cost is 42$ after 20 visits
