Answer:
A
Step-by-step explanation:
We want to find the equation of the line in slope-intercept form.
From the graph, we are given the two points (-5, 1) and (0, -3).
We can find the slope between them. The slope formula is given by:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We will let (-5, 1) be (x₁, y₁) and (0, -3) be (x₂, y₂). Substitute:
[tex]\displaystyle m=\frac{(-3)-(1)}{(0)-(-5)}[/tex]
And evaluate:
[tex]\displaystyle m=\frac{-4}{5}=-\frac{4}{5}[/tex]
Next, notice that the point (0, -3) is already the y-intercept, so we do not need to find it.
Slope-intercept form is given by:
[tex]\displaystyle y=mx+b[/tex]
Therefore, our equation is:
[tex]\displaystyle y=-\frac{4}{5}x-3[/tex]
Our answer is A.
Tameka borrowed $300 to buy a digital music player she will pay the money back in 1 year at 5%simple interest how much money will tameka pay in interest
Answer:
$15 in interest
Step-by-step explanation:
sorry if it is wrong. I found 5% of 300 which is 15.
$15 money will tameka pay in interest.
What is interest?
Interest is the price you pay to borrow money or the cost you charge to lend money. Interest is most often reflected as an annual percentage of the amount of a loan. This percentage is known as the interest rate on the loan.
Here, we have,
formula: I = Prt.
here, we get,
given that,
Tameka borrowed $300 to buy a digital music player she will pay the money back in 1 year at 5%simple interest.
P=$300
r=5%
t=1year
so, I =$300*5%*1
=$15
Hence, $15 money will tameka pay in interest.

How can you determine the number of solutions of a system of linear equations by inspecting its equations?
Step-by-step explanation:
To find - How can you determine the number of solutions of a system
of linear equations by inspecting its equations?
Proof -
There exists three types of solution for a system of linear equations.
1. No solution.
2. Unique solution.
3. Infinite many solutions.
Now,
Let the 2 linear equations are as follows :
y = ax + b
y = cx + d
1. For no solution -
a = c and b ≠d
For example-
y = -2x + 5
y = -2x - 1
Subtract first equation from second , we get
y - y = -2x - 1 - ( -2x + 5)
⇒0 = -2x - 1 + 2x - 5
⇒0 = -6
Not possible
So, There exist no solution.
2. For unique solution -
a ≠ c and b , d can be any value
For example -
If b and d are same ,
y = 2x - 4
y = -3x - 4
Subtract equation 1st from 2nd , we get
y - y = -3x - 4 - ( 2x - 4)
⇒0 = -3x - 4 - 2x + 4
⇒0 = -5x
⇒x = 0
⇒y = 2(0) - 4 = -4
∴ we get
x = 0, y = -4
If b and d are different
y = 2x - 4
y = -3x + 5
Subtract equation 1st from second
y - y = -3x + 5 - 2x + 4
⇒0 = -5x + 9
⇒-5x = -9
⇒x = [tex]\frac{9}{5}[/tex]
⇒y =2([tex]\frac{9}{5}[/tex]) - 4 = [tex]\frac{18}{5} - 4 = \frac{18 - 20}{5} = -\frac{2}{5}[/tex]
∴ we get
x = [tex]\frac{9}{5}[/tex] , y = [tex]-\frac{2}{5}[/tex]
3. Infinitely many solution -
a = c and b = d
For example -
y = -4x + 1
y = -4x + 1
Subtract equation first from equation second
y - y = -4x + 1 - ( -4x + 1)
⇒0 = -4x + 1 + 4x - 1
⇒0 = 0
Satisfied
So, Infinite many solution possible.
3) The cost of a movie ticket and a candy bar is $5. The cost of 2 tickets
and a candy bar is $8.75. How much is a candy bar? *
Answer:
$1.25
Step-by-step explanation:
Given data
let the movie ticket be x and the candy bar be y
x+y= 5-------------1
also
2x+y= 8.75--------2
solve 1 and 2
x+y= 5
2x+y= 8.75
from 1
x= 5-y
put this inplace of x in 2
2(5-y)+y=8.75
10-2y+y= 8.75
10-y= 8.75
10-8.75=y
y= 1.25
Hence candy bar is $1.25

What’s the value of x?
Answer:
6*15 = 5(x+5)
90 = 5x + 25
65 = 5x
x = 13
Step-by-step explanation:
I've gone ahead and labeled some points.
There is a formula that says PA*PB = PC*PD, this is what you use. If you would like me to show why this works I would be happy to.
So what we have is PA = 6, PB = 9+6 = 15, PC = 5 PD = 5+x so let;s writ ethe formula with these values
6*15 = 5(x+5)
90 = 5x + 25
65 = 5x
x = 13
EDIT: Here is the explanation for the formula
If you form triangles PCB and PAD you can find angle D and angle B are the same, because they are inscribed angles that intersect the same arc of the circle. Also angle P is the same on both triangles since they are the same angle, so this means both triangles are similar.
This means DA is similar to BC, AP is similar to CP and PD is similar to PB. Similar sides means if you can multiply one side by a number to get to its similar side, then you can multiply all sides by that value to get all sides of that similar triangle.
This also means if you divide one side by its similar side you get the scale value, so this means if you do it to two different sets of similar sides you get the same number
[tex]\frac{PA}{PC}=\frac{PD}{PB}\\PA*PB = PC*PD[/tex]

Alyson earned $40 in commission from her sales. How much did she sell if her commission rate is 15%?
Answer:
$266.67 (Verified) ✅Step-by-step explanation:
Let the merchandise she sold = x
Her commission is 15% of that, so 15% of x or 0.15x
We know her commission was $40, so 0.15x = $40
0.15x = $40
Divide by 0.15
x = $266.67
We can check our answer by substituting $266.67 back into the equation.
0.15(266.67) = 40
40 = 40 ✅
Alyson sold $266.67 worth of merchandise.
