Answer:
Yes, the cost per order is a linear function of the number of copies you order (up to 100).
Step-by-step explanation:
Let;
y = Total cost of order from one copy up to 100 copies or dependent variable
a = Cost of 50 copies or fixed intercept
x = Cost of 51 copies or more up to 100 copies or dependent variable, i.e. 51 = x [tex]\leq[/tex] 100
b = Coefficient of x = 1 - Discount rate = 1 - 15% = 1 - 0.15 = 0.85
We can therefore represent have a function as follows:
y = a + bx ........................ (1)
Substituting b = 0.85 into equation (1), we have:
y = a + 0.85x ...................... (2)
Equation (2) implies that as b equal to 51 or more up to 100, y also increases. Equation (2) is therefore an example of linear function which will give an upward sloping straight line and can be rewritten as:
y = f(x) = a + 0.85x ................. (3)
Therefore, the cost per order is a linear function of the number of copies you order (up to 100).
Rewrite the following expression using the distributive property: 12x + 20
Answer: 4(3x +5) or 2(6x +20)
Step-by-step explanation:
a squares side are increased by five inches. Find the length of the original square if the perimeter of the new square is 100 inches. Length of side of original square: ______
inches
Answer:
The length of side of original square is: 20 inches
Step-by-step explanation:
Let x be the length of side of original square
Then x+5 will be the side of new square
Th formula for perimeter is:
[tex]P = 4*side[/tex]
As we know the perimeter of the new square we can use the perimeter to find the value of x
[tex]100 = 4 * (x+5)\\100 = 4x+20\\4x = 100-20\\4x = 80\\\frac{4x}{4} = \frac{80}{4}\\x = 20[/tex]
The value of x is 20 inches.
Hence,
The length of side of original square is: 20 inches

Lance’s team made 16 out of the 25 free-throws they attempted. What percent of the free-throws did the team make?
Answer:
64%
Step-by-step explanation:
16/25
Answer:
64%
Step-by-step explanation:
if they made 16/25 free-throws, you would multiply each side by 4 in order to get 100% on the right side, and if you multiply 16 by 4 it is 64

In physics, the current (I), potential difference (V), and resistance ® of an electrical circuit are known to stand in the following relation. i=V/R Which of the following is the same equation solved for V?A. V=IR B. V= I(1-R) C. V=I/R D.V=R/I
Answer:
Step-by-step explanation:
The current that flows through most substances is directly proportional to the voltage V applied to it. The German physicist Georg Simon Ohm (1787–1854) was the first to demonstrate experimentally that the current in a metal wire is directly proportional to the voltage applied: I∝V I ∝ V .

At a rap concert, the ratio of the number of boys to the number of girls is 9: 5. If there
are 320 more boys than girls, how many boys and how many girls are at the concert?
Answer:
177.78
Step-by-step: Let's solve your equation step-by-step.
9
5
=
320
x
Step 1: Cross-multiply.
9
5
=
320
x
9*x=(320)*(5)
9x=1600
Step 2: Divide both sides by 9.
9x
9
=
1600
divided by 9 which will give you 177.78
What is the Equation of this Trend line
K=_ J+_
Answer:so the standard form is y = mx + b
m is the slope (rise/run)
b is the y-intercept or where the slope intercepts the y-axis
so you end up with
k = (4/-2)j + 24
simplify this to
k = -2j + 24
Step-by-step explanation:
Fill in the table using this function rule.
y = 4+4x
X Y
2
3
4
10
Fill in the y area
12, 16, 20, 44
Just substitute the number on the x side of the table for x in the equation and solve to get the y value.
The completed table of Y values using the function rule y = 4 + 4x is as follows:
X Y
2 12
3 16
4 20
10 44
To fill in the Y values using the function rule y = 4 + 4x, we substitute the given X values into the equation and solve for Y.
When the value of X = 2:
4 + 4(2) = 4 + 8 = 12
When the value of X = 3:
4 + 4(3) = 4 + 12 = 16
When the value of X = 4:
4 + 4(4) = 4 + 16 = 20
When the value of X = 10:
4 + 4(10) = 4 + 40 = 44
The completed table is as follows:
X Y
2 12
3 16
4 20
10 44

Answer:
d = 2.75 or 11/4
Step-by-step explanation:
15 = 5 + 4(2d - 3)

15 = 8d - 7
+7 + 7
22 = 8d
22/8 = d
2.75 = d

Answer:
Option D: 66 degrees
Step-by-step explanation:
Interior angles of a triangle add up to 180 degrees.
Thus, 90+24+x=180 would be the equation you make to solve:
90+24+x=180
114+x=180
x=66
So <x=66 degrees
