Answer:
$7
Step-by-step explanation:
I ordered 4 new CD's by mail. Each CD costs the same amount and there was an additional $5 shipping charge that brought the total to $33. Write and solve the equation to find the cost of one CD.
Let us represent the cost of 1CD = x
Total cost = $5 + 4x
= 5 + 4x
Total cost = $33
Hence, our Equation is given as:
33 = 5 + 4x
4x = 33 - 5
4x = 28
x= 28/4
x = $7
The cost of 1 CD = $7
What’s the value of x
Answer:
-10
Step-by-step explanation:
-5x - 1 = -10x - 51
Add 10x to both sides.
5x - 1 = -51
Add 1 to both sides.
5x = -50
Divide both sides by 5.
x = -10
I hope this helped! :)

Given the equation find the y-intercept. Write it as a coordinate ( 0 , y ).
y=-4x+3
Answer:
(0, 3)
Step-by-step explanation:
The equation already shows the y-intercept (written as +3). The slope is -4x and the y-intercept is (0, 3).
Answer:
y=3
Step-by-step explanation:
Because we know x equals 0 we put that into the equation so then you have y=4(0)+3 you multiply 4 time 0 and get 0 so all you have left is 3.

The terms in the sequence decrease by the same amount each time:
9, 6 ,3 ,0, -3, -6
Work out ,in term of n, the nth term of the sequence
Answer:the nth term of the sequence, Tn= -3n +12
Step-by-step explanation:
The nth term of an arithmetic progression is given as
Tn= a+ (n-1) d
where a= first term
and d = common difference
In this sequence, 9, 6 ,3 ,0, -3, -6 we can see that the number is decreasing by 3
The first term, a= 9
and common difference, d = -3
using our formulae
Tn= a+ (n-1) d
Tn= 9 + ( n-1) -3
Tn=9- 3n+ 3
Tn= -3n +12

in the figure below, what are the values of x and y? What are the measures of the four angles in the figure
Answer:
a. x=57.6, y=44.8
Step-by-step explanation:
Named the angles, check the picture for that
<ABD+<ACD=180 (Opposite angles of a quadrilateral is supplementary (180 degrees)
<CAB+<BDC=180 (Opposite angles of a quadrilateral is supplementary (180 degrees)
therefore:
a. 3y+x-12=180.............. equ 1
2x+y+20=180.............equ 2
From equ 1
x+3y=180+12
x+3y=192...............equ 3
From equ 2
2x+y=180-20
2x+y=160.............equ 4
Equate equ 3 and equ 4
x+3y=192...............equ 3
2x+y=160.............equ 4
Using elimation method
x+3y=192...............equ 3
2x+y=160.............equ 4
Multiple equ 3 by 1 and equ 4 by 3
x+3y=192...............equ 3 ×1
2x+y=160.............equ 4 ×3
x+3y=192
6x+3y=480
Subtract
-5x+0=-288
-5x=-288
x=57.6................... Equ 5
Replace 57.6 for x in equ 3
x+3y=192...............equ 3
57.6+3y=192
3y=192-57.6
3y=134.4
y=44.8
B. <CAB= 2x=2×57.6=115.2
<ABD= 3y=3×44.8= 134.4
<ACD=x-12=57.6-12=45.6
<BDC=y+20=44.8+20=64.8

Boden's account has a principal of $300 and a simple interest rate of 3.8%. Complete the number line. How much money will be in the account after 4 years, assuming Boden does not add or take out any money?
Answer:$66.00
Step-by-step explanation:
first we need multiply :D I will use the formula I =prt
principal= $500
rate=3.3%
time= 4 years
but we need to convert the percent, 3.3%, to a decimal
3.3%=0.033 or .033
then we multiply
500 × 0.033 × 4 = 66 = $66.00
What is a formula for the nth term of the given sequence?
36, -48, 64...
Answer:
A formula for the nth term of the given sequence is:
[tex]a_n=36\left(-\frac{4}{3}\right)^{n-1}[/tex]
Step-by-step explanation:
Given the sequence
36, -48, 64...
We know that a geometric sequence has a constant ratio r and is defined by
[tex]a_n=a_1\cdot r^{n-1}[/tex]
Compute the ratios of all the adjacent terms
[tex]\frac{-48}{36}=-\frac{4}{3},\:\quad \frac{64}{-48}=-\frac{4}{3}[/tex]
The ratio of all the adjacent terms is the same and equal to
[tex]r=-\frac{4}{3}[/tex]
Therefore, the given sequence is a geometric sequence.
As the first element of the sequence is
[tex]a_1=36[/tex]
so substituting [tex]a_1=36[/tex] and [tex]r=-\frac{4}{3}[/tex] in the nth term
[tex]a_n=a_1\cdot r^{n-1}[/tex]
[tex]a_n=36\left(-\frac{4}{3}\right)^{n-1}[/tex]
Therefore, a formula for the nth term of the given sequence is:
[tex]a_n=36\left(-\frac{4}{3}\right)^{n-1}[/tex]

Type the correct answer in the box. Use numerals instead of words. Find the area of this shape. The area of the shape is square centimeters.
Answer: 35cm²
Step-by-step explanation:
This is a composite shape so break it down into its individual shapes and get their areas then add them up to find the shape's total area.
Area of Triangle:
= 1/2 * base * height
= 1/2 * 8 * 5.75
= 23 cm²
Base = 4 + 4 = 8cm
Area of the Trapezium
= (a + b) / 2 * height
a is top length
b is bottom length
= (4 + 8) / 2 * 2
= 12 cm²
Add them up:
= 23 + 12
= 35cm²

of a football team's season touchdowns, about 43% came by passing. If the team scored 28 touchdowns, how many were by other means?
43% were from passing so 100% - 43% = 57% came by other means.
28 x 57% = 28 x 0.57 = 16
16 came from different means.

The zoo is open for 9 hours on weekdays. On weekends, the zoo is open for r
more hours. Write the expression for the number of hours the zoo opens on
weekends.
Answer:
36-k
Step-by-step explanation:
1. E = -20,000p + 90,000
R = -2,170p2 + 87,000p
The equations of E and R are illustrations of cost and revenue functions
The equation of the break even point is -20,000p + 90,000 = -2,170p^2 + 87,000p
How to determine the break even pointThe cost and the revenue functions are given as:
E = -20,000p + 90,000
R = -2,170p^2 + 87,000p
At the break even point, we have:
E = R
Substitute known values
-20,000p + 90,000 = -2,170p^2 + 87,000p
Hence, the equation of the break even point is -20,000p + 90,000 = -2,170p^2 + 87,000p
