Last month you purchased 6 individual songs and 1 albums for a total of $21.99.
This month you spent a total of $44.97 on 4 individual songs and 3 albums.
How much does each song and album cost
Answer:
Song =$1.50 Album =$12.99
Step-by-step explanation:
Lets assume Individual songs = x
albums=y
6x + y = 21.99-------- y= 21.99- 6x
4x + 3y= 44.97
Replace y in the second equation
4x+ 3(21.99-6x) = 44.97
4x +65.97- 18x = 44.97
14x= 21
x = 1.50
y= 21.99- (6*1.50)
= 12.99
X2-12x+21=-6 solve the quadratic by factoring
Answer:
(x-3)(x-9)
Step-by-step explanation:
first thing you need to do is move the -6 over. so we're going to add 6 to both sides (we add because it's negative 6 and we need 0 on the right side)
so you have: x^2-12x+27
now we need to come up with two numbers that add to -12 and multiply to 27.
the factors of 27 are 9 & 3 and 27 & 1. only 9 & 3 add to 12 so we are going to use those.
since the 12 is negative however, 9 and 3 should both be negative.
therefore we get: (x-3)(x-9)
*it doesn't matter which order you put them in!
Find two numbers that multiply to 16 and also add to -8
Answer:
-4,-4
Step-by-step explanation:
let the numbers be x and y.
x+y=-8
y=-x-8
xy=16
x(-x-8)=16
-x²-8x=16
x²+8x+16=0
x²+4x+4x+16=0
x(x+4)+4(x+4)=0
(x+4)(x+4)=0
x=-4,-4

Answer:
D. PerpendicularStep-by-step explanation:
First answer A. Answer A is not even correct. Parallel are two or more lines that NEVER cross
Answer B is also not correct. Line segments are a line of specific length. These are two LINES. You can tell by the arrows on the edge of each line.
Both C and D can be correct. But the answer would be D. Here is why
Intersecting lines are two or more lines that cross. Yes these lines are crossing by perpendicular lines also cross. The difference is, intersecting lines can cross at any angle. Perpendicular lines have to cross at 90 degrees making 4 right corners.

Answer:
Volume= 360 feet³
Step-by-step explanation:
We have two shapes, a triangular prism and a rectangular prism.
Rectangular Prism: [tex]w=6, h=2, l=8, V=lwh[/tex]
So, the volume is 6×2×8=96 feet³
Triangular Prism: [tex]h=5.5-2=3.5, w=6, l=8, V=\frac{1}{2}lwh[/tex]
So, the volume is (5.5×6)÷2 ×8= 33×8=264 feet³
We have to combine the two volumes to find the volume of the whole shape. 96+264=360. So, the volume of the whole shape is 360 feet³

What is the value of the expression below when w=3?
10w2 +9w-2
Answer:
85 if the "2" in 10w(2) is being multiplied.
But if not, then
115 if the "2" in 10w2 is an exponent.
Answer:
85
Step-by-step explanation:
10(3)2 + 9(3)-2
(30)2 + (27)-2
60+25=85

Answer:
B and E
Step-by-step explanation:
-14 is the answer that is used to see if they are equal or not
A is incorrect because it equals -6.
B is correct because it equals -14.
C is incorrect because it equals 6.
D is incorrect because it equals -6.
E is correct because it equals -14.
Write an equation in slope-intercept form for the line that passes through the
given point and is parallel to the graph of the given equation.
(-1, -2), 3x - y = 5
Answer:
y = 3x + 1
Step-by-step explanation:
the slope of the line of the given equation can bé find in this way: -a/b, where a is the number that multiplies x and b is the number that multiplies y
m = -3/-1 = 3
two parallel lines have the same slope, so also the line that we are a searching has m=3
now we can use this formula
y-y1 = m(x-x1) where y1 and x1 indicate the coordinates of the given point
y-(-2) = 3 (x-(-1)
y+2 = 3x + 3
y = 3x + 3-2
y = 3x + 1

An experiment consists of spinning a spinner. Use the results in the table to find the experimental probability of the spinner not landing on red.
Red = 8
Blue = 7
Green = 9
Yellow = 6
A. 3/5
B. 11/15
C. 2/5
D. 4/15
Answer:
Probability(Not red) = 11 / 15
Step-by-step explanation:
Given:
Outcomes;
Red = 8
Blue = 7
Green = 9
Yellow = 6
Find:
Probability(Not red)
Computation:
Probability(Not red) = 1 - Probability(red)
Probability(Not red) = 1 - [Number of red/ Total]
Probability(Not red) = 1 - [8/(8+7+9+6)]
Probability(Not red) = 1 - [8/30]
Probability(Not red) = 1 - [4/15]
By taking LCM
Probability(Not red) = (15 - 4) / 15
Probability(Not red) = 11 / 15
Suppose that the population of deer in a state is 7,700 and is growing 3% cach year. Predict the population
after 5 years
Answer:
Future Value= 8,927
Step-by-step explanation:
Giving the following information:
Present Value (PV)= 7,700
Growth rate (g)= 3%
Number of periods (n)= 5 years
To calculate the future value (FV) of the population after 5 years, we need to use the following formula:
FV= PV*(1 + g)^n
FV= 7,700*(1.03^5)
FV= 8,927

Which function is best represented by this graph?
A y = 1/4 x + 8
B y = 1/4 x - 2
C y = 4x -2
D y = 4x + 8
⚠️Hurry⚠️
Answer:
B- y=[tex]\frac{1}{4}[/tex]x-2
Step-by-step explanation:
To look at the slope you can count over four and then up one and its at the next point.
Also, the place on the y-axis is at -2
So, b makes the most since :)
Hope this helps :) (if it does, brainliest??)
