Determine if the function is linear.
Show your work.
Answer:
Yes it is
Step-by-step explanation:
In order to find it, you just need to find the slope which the equation is y2-y1/x2-x1
Giving you the slope to be -5/3
and the b value is 16 bc it is 16 at 0
slope equation is y= mx + b
plug -5/3X+16 into your graphing calculator and see that it is a straight line and boom.
3 more than eight times a number is equal to 19
a. 8n = 19 + 3
b. 8n - 3 = 19
c. 8n + 3 = 19
d. n/8 + 3 = 19
Answer: C. 8n+3=19
8 times a number: 8n
3 more: +3
equals 19:=19

A tower has a revolving restaurant 840 feet above the ground. The restaurant makes a complete revolution every 60 minutes. While a visitor was at the tower, the restaurant rotated through 126°. How long was the visitor at the tower? The visitor was at the tower for minutes.
Answer: 21 minutes
Step-by-step explanation: A complete revolution has 360°. The tower rotates completely after 60 minutes, which means:
360° - 60 min
The restaurant rotated 126° while the visitor was at the tower, so using proportionality rule:
360° - 60 min
126° - t min
[tex]t=\frac{126*60}{360}[/tex]
[tex]t=\frac{126}{6}[/tex]
t = 21
The visitor was at the tower for 21 minutes.

(1) A farm has 15 rows of fruit trees with 7 trees in each row. The last 4 rows of trees are cherry trees. The remaining trees are orange trees. How many orange trees are on the farm?
(2) At the bakery, there are 5 rows with 12 chocolate chip cookies on each tray. There are 2 trays with 14 cookies on each tray. If 7 cookies are sold. How many cookies are left?
Answer:
Step-by-step explanation:
1) If a farm has 15 rows of fruit trees with 7 trees in each row, the total number of trees in the farm will be 15*7 = 105 trees
If the last four rows of trees are cherry trees, the total numner of cherry trees will be 4 * 7 = 28 trees
Let the total trees in the farm = number of cherry trees + orange trees
orange trees = total trees - cherry trees
orange trees = 105 - 28
orange trees = 77 tress
Hence there are 77 orange trees in the farm
2) If at the bakery, there are 5 rows with 12 chocolate chip cookies on each tray, the total number of cookies on the tray will be 5 * 12 = 60 chocolate cookies
Also if there are 2 trays with 14 cookies on each tray, the total cookies on both tray s will be 2 * 14 = 28 cookies
If 7 cookies are sold, the number of cookies left will be 28 - 7 = 14 cookies
Hence 14cookies will be left over

Answer:
3/5, -12 12/15, 51/125
Step-by-step explanation:
just did it
Answer:
3/5; -12 12/25; 51/125
Step-by-step explanation:
Write the first one just like you would say it. You would read 0.6 as six tenths, therefore your answer is 6/10, but don't forget to simplify to 3/5.
Next, you have -12.48. -12 is going to be your whole number. However, you still have 0.48 left so you would write it just how you would say it. You would say it as forty-eight hundredths which is why you would write it as 48/100. Now you just have to simplify it into 12/25. Thus, your final answer would be -12 12/25.
Finally, you have 0.408 which is read as four hundred eight thousandths. Your fraction would then be 408/1000. Now simplify to 51/125.
A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find out the time at which the rocket will reach its max, to the nearest 100th of a second. y=-16x^2+263x+92
Answer:
8.39 seconds
Step-by-step explanation:
Given the equation which models the height of a rocket:
y=-16x^2+263x+92
Time taken to reach maximum height ; = total total time of flight / 2
Total time of flight is obtained at h = 0
Hence +,
y=-16x^2+263x+92 ; y = 0
-16x^2+263x+92 = 0
Using the Quadratic equation solver :
X = 16.78 or x = -0.3466
Time can't be negative
Hence, total time of flight= 16.78
Therefore, time taken to reach maximum height :
Total time of flight / 2
= 16.78 / 2
= 8.39 seconds

Mike wants to save $1,750 in the next 12 months. He plans to save $150 each month for the first 11 months. Part A What is the total amount of money Mike will save during the first 11 months if he saves $150 each month? Enter your answer in the box. $ Part B Mike plans to save the same amount in the 12th month as in each of the other months. Will Mike be able to save $1,750 in the 12 months? Enter numbers in the boxes to solve the problem. Since $1,750 – $ = , Mike will need to save $ in the 12th month. Since $ is less than $150, he will be able to reach his goal.
Answer:
A. $1,650
Mike will reach his goal if he saved $100 in the 12th month if he has been saving $150 for the first 11 months
Step-by-step explanation:
Mike wants to save $1,750 in the next 12 months.
He plans to save $150 each month for the first 11 months.
A. Total amount of money Mike will save during the first 11 months if he saves $150 each month is
$150 × 11 months
= $1,650
B. If Mike plans to save the same amount in the 12th month ($150) as in each of the other month
= $150 × 12 months
= $1,800
He will be able to save $1,750 if Mike saved the same amount in the 12th month
In the 12th month, Mike only needs to save $100 if he has saved $150 in the first 11 months in order to reach his goal

Laura corto un trozo de tela cuadrada para un mantel. Luego se dio cuenta de que ese trozo no alcanzava a cubrir la superficie pues, había un error de medidas. Pará arreglarlo le agrego dos prendas haciendo el el mantel ahora sea rectangular, su largo mide 50 cm mas y su ancho 3o cm más que las medidas del mantel original. Si el nuevo mantel cubre 16800 cm2 ¿cuál es la medida del lado del primer mantel y cuantos cm2 cubría?
Answer:
La medida del lado del primer mantel es 90 centímetros.
Primer mantel cubría un área de 8100 centímetros cuadrados.
Step-by-step explanation:
Sea [tex]x[/tex] la longitud del lado del mantel original, cuya forma es cuadrada y está medida en centímetros. Al agregarse dos prendas, se obtiene un rectángulo, cuya área ([tex]A[/tex]), medida en centímetros cuadrados, se halla mediante la siguiente fórmula:
[tex]A = w\cdot l[/tex] (Eq. 1)
Donde:
[tex]w[/tex] - Ancho, medido en centímetros.
[tex]l[/tex] - Largo, medido en centímetros.
Si [tex]A = 16800\,cm^{2}[/tex], [tex]l = x+50\,cm[/tex] y [tex]w = x+30\,cm[/tex], tenemos el siguiente polinomio de segundo orden:
[tex]16800 = (x+50)\cdot (x+30)[/tex]
[tex]16800 = x^{2}+80\cdot x +1500[/tex]
[tex]x^{2}+80\cdot x -15300 = 0[/tex]
Por la fórmula de la Cuadrática tenemos que las raíces del polinomio son:
[tex]x_{1} = 90\,cm[/tex], [tex]x_{2} = -170\,cm[/tex].
Solamente la primera raíz es una solución físicamente razonable. Entonces, la medida del lado del primer mantel es 90 centímetros.
Ahora, el área del primer mantel es:
[tex]A = (90\,cm)^{2}[/tex]
[tex]A = 8100\,cm^{2}[/tex]
Primer mantel cubría un área de 8100 centímetros cuadrados.

A quadratic equation has an axis of symmetry at x = 7 and has a
maximum value at -3. Write the equation.
g(x) = -3(x – 7)?
O g(x) = -(x + 7)2 – 3
O g(x) = -(x – 7)2 – 3
og(x) = (x – 7)2 – 3
Answer:
g(x) = (x - 7)² - 3
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (7, - 3) and a = 1, thus
g(x) = (x - 7)² - 3
f(x)=3x-9 and g(x)=-5x+8, find (f-g)(x)
Answer:
Step-by-step explanation:
3x - 9 - (-5x + 8)
3x - 9 + 5x - 8

Company A rents copy machines for $300 a month plus $0.05 per copy. Company B charges $600 a month plus $0.01 per copy. For which number of copies do the two companies charge the same amount?
Answer:
7,500 copies
Step-by-step explanation:
First, write the problems as equations. There will be one variable: copies (c):
Company A: .05c + 300
Company B: .01c + 600
In order to find when the companies charge the same amount, Company A = Company B. Using the transitive property you get:
Company A = Company B
.05c + 300 = .01c + 600
Now, you just need to solve for c:
.05c + 300 = .01c + 600
.05c = .01c + 300
.04c = 300
c = 7,500
In conclusion, the companies will charge the same amount of money when 7,500 copies are made in a month.

Chuck has $2,345 he is buying gift cards for some of his friends and each gift card costs $85 whats the greatesy amount of gift cards can he buy and how much money will he have left?
Answer:
$50Step-by-step explanation:
Chuck has $2,345 in total
if one gift card cost $85
we want to find the total number of cards that $2,345 can buy.
so we have to divide $2,345 by $85
= $2,345/85
=27card in total
27*85=$2295
the amount left is
= $2,345 -$2295
=$50
therefore the amount left is $50
