PLEASE HELP As a part-time job, ethan makes deliveries for a caterer. In addition to his weekly salary, he is also paid 16$ Per delivery. Last week, he made 5 deliveries and his total salary was $215. Write a linear equation to find Ethan's total weekly salary S if he makes d deliveries.
you know he made 5 deliveries for $16 each. 5*16=80. So to find his salary you have 215-80=$135.
So he makes $135 no matter what plus $16 times the number of deliveries.
so, S=16d+135
Solve the equation.

and then
x=105105
is equal to
2
so...
x=2
Answer: Hey user! x = 2.
Step-by-step explanation: Step 1: Divide both sides by 5.

Peter works as a delivery person for a bike shipping company. The graph shows a linear model for his
delivery times on different days.
(a) what is the equation of the line, first written in point-slope form and then written in slope- intercept form? show how you determined the equation.
(b) based on the linear model, predict how long it initially took peter to deliver his packages (y-intercept) approximately how much did his delivery time decrease per day (slope)? Complete sentences
Answer/Step-by-step explanation:
a. Using a point on the graph, (6, 12), and the slope of the line, we can first generate an equation in the point-slope form, given as [tex] y - b = m(x - a) [/tex], where,
m = slope, and (a, b) is a point on the line.
Using two points, (6, 12) and (3, 21), let's find slope, m.
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{21 - 12}{3 - 6} = \frac{9}{-3} = -3 [/tex]
Using a point (6, 12) and slope, m = -3, generate an equation in the point-slope form by substituting a = 6, b = 12, and m = -3 in [tex] y - b = m(x - a) [/tex].
✅Equation in point-slope form would be:
[tex] y - 12 = -3(x - 6) [/tex]
Rewrite this to make it be in the slope-intercept form, [tex] y = mx + b [/tex].
[tex] y - 12 = -3(x - 6) [/tex]
[tex] y - 12 = -3x + 18 [/tex]
Add 12 to both sides
[tex] y = -3x + 18 + 12 [/tex]
[tex] y = -3x + 30 [/tex]
✅The equation in slope-intercept form is [tex] y = -3x + 30 [/tex]
b. ✍️Based on the linear model, [tex] y = -3x + 30 [/tex], the 30 represents b = y-intercept.
✅Therefore, it took Peter 30 mins long initially to deliver his package.
✍️Based on the linear model, [tex] y = -3x + 30 [/tex], "-3" represents the slope.
✅Therefore, Peter's delivery time decreased 3 mins per day.

Let g(x) = 9x + 24
find g(3)
Let g(x)=9x+24, find g(3).
Answer:
51
Step-by-step explanation:
Plug in 3 as x into the function:
g(x) = 9x + 24
g(3) = 9(3) + 24
g(3) = 27 + 24
g(3) = 51
g(x) = 9x + 24
g(3) = 9(3) + 24
g(3) = 27 + 24 = 51
Answer:g(3) = 51

50 is 20% of what ? Round to the nearest tenth is needed
Answer:
250
Step-by-step explanation:
20% of 250 is 50. 100% of 250 is 250, therefore 20 percent of 250 equals 50.
More simplified explanation: The question is asking if 50 is 20% of a number, what is the number? So we know that 20% is 1/5 of 100%; if we know that 50 is 20% of something, then we would multiply 50 by 5 to get the answer. We would have to multiply 50 by 5 because if 50 is 20% of a number that would mean that 50 is 1/5 of the number we need to find, so to find the number, you to multiply 50 by 5.

If the equation y=3x−1 y = 3 x − 1 were graphed on the xy-coordinate plane, which of the following would not be a point on that graph?
Answer:
See Explanation
Step-by-step explanation:
This question requires options.
Since, there are none, I'll answer on a general term.
For a coordinate point to be on the graph, the x and y value when substituted in the given equation must make the equation true.
Take for instance
(x,y) = (1,2)
This implies that
x = 1
y = 2
Substitute values of x and y in
y = 3x - 1
We have:
2 = 3 * 1 - 1
2 = 3 - 1
2 = 2
Notice that both sides of the equation are equal.
Hence
(1,2) lies on the xy coordinate plane.
However,
Take for instance (x,y) = (2,4)
This means
x = 2 and y = 4
Substitute values of x and y in
y = 3x - 1
4 = 3 * 2 - 1
4 = 6 - 1
4 ≠ 5
The above does not represent an equation because 4 is not equal to 5.
Hence, (2,4) does not lie on the coordinate plane
So, to answer your question, you need to substitute values of x and y in the given equation.
Which ever of the options that does not show equality answers your question.
a store is having a 20% off so on all
merchandise if made buys one item and saves $13 what was the original price of the purchase explain or show your reasonings
Answer:
If a store is having a 20% off sale
By buying an item you save 20% of the price
If Mai saves $13 on an item she is also saving 20%
$13 = 20% of the price
$65 = 100% of the original price
$65 is your answer!

A group of cubes are arranged in a pattern with the same number of cubes in each row and column. There are 225
cubes in the shape. How many cubes are in one row?
A)
15
B)
25
0
56
D)
75
Given:
Total number of cubes = 225
Cubes are arranged in a pattern with the same number of cubes in each row and column.
To find:
The number of cubes in a row.
Solution:
Let the number of cubes in a row be x.
Since, cubes are arranged in a pattern with the same number of cubes in each row and column, therefore number of cubes in rows and columns are equal.
[tex]\text{Total cubes}=x\times x[/tex]
[tex]\text{Total cubes}=x^2[/tex]
Total number of cubes = 225
[tex]x^2=225[/tex]
Taking square root on both sides.
[tex]x=\sqrt{225}[/tex]
[tex]x=15[/tex]
So, the number of cubes in a row is 15.
Therefore, the correct option is A.

Población de alces. Se introducen cíen alces en una reserva zoológica, cada uno de un año de edad. El número N(t) de animales vivos después de t años se predice mediante N(t) = 100(0.9) t Estima el número de animales vivos después de:
Answer:
El número de animales vivos después de 1, 5 y 10 años es 90, 60 y 35 respectivamente.
Step-by-step explanation:
Sabes que el número N(t) de animales vivos después de t años se predice mediante N(t) = 100*[tex]0.9^{t}[/tex]
Para estimar el número de animales vivos después de, por ejemplo, 1 año debes simplemente reemplazar el tiempo t por el tiempo correspondiente, en este caso 1 año:
N(1) = 100*[tex]0.9^{1}[/tex]
Resolviendo:
N(1) = 100*[tex]0.9^{1}[/tex]= 100*0.9= 90
De manera similar, podes estimar el número de animales vivos después de 5 y 10 años. Esto es, reemplazas t por 5 años:
N(5) = 100*[tex]0.9^{5}[/tex]= 100*0.59049= 59.049≅ 60
y t por 10 años:
N(10) = 100*[tex]0.9^{10}[/tex]= 100*0.3487= 34.86 ≅ 35
El número de animales vivos después de 1, 5 y 10 años es 90, 60 y 35 respectivamente.
