Answer:
[tex]y=\frac{5}{6}x+2\frac{2}{3}[/tex]
Step-by-step explanation:
From the point (-2,1) to the point (4,6)
there is a [tex]\frac{rise}{run}[/tex] of [tex]\frac{5}{6}[/tex], or a slope of [tex]\frac{5}{6}[/tex]
[tex]rise=[/tex] the change in y
[tex]run=[/tex] the change in x
To get the y-intercept we just have to use the formula: [tex]b=y-mx[/tex]
[tex]b=[/tex] y-intercept
[tex](x,y)=[/tex] point on the line
[tex]m=[/tex] slope
[tex]b=1-(\frac{5}{6})(-2)[/tex]
[tex]b=1+\frac{5}{3}[/tex]
[tex]b=2\frac{2}{3}[/tex]
So the equation of the line is: [tex]y=\frac{5}{6}x+2\frac{2}{3}[/tex]

A salesperson receives a 3% commission on sales. The salesperson receives $180 in commission. What is the amount of sales?
Thank you :)
Answers
Answer:
$6,000
Step-by-step explanation:
Form an equation
let s be the amount of sales
You know that the salesperson gets 3%, or 0.03 of the sales, so:
0.03x = 180
Then, solve
[tex]0.03x=180[/tex]
multiply both sides by 100 to get rid of the decimal
[tex]3x=18000[/tex]
divide both sides by 3
[tex]x=6000[/tex]
So the amount of sales is $6,000
Given the statement ΔQRS ≅ ΔXYZ, list all congruent parts you can conclude about the two triangles. Explain.
Answers
Answer:
Side QR is congruent to Side XY.
Side RS is congruent to Side YZ.
Side SQ is congruent to Side ZX.
Angle Q is congruent to Angle X.
Angle R is congruent to Angle Y.
Angle S is congruent to Angle Z.
Step-by-step explanation:
Side QR is congruent to Side XY because triangle QRS is congruent to triangle XYZ and each point of a triangle is in corresponding order with a point of the other triangle. For example, Q matches up with X since they both are listed first in their respective sequence.

Help! - Conjectures With Angles
Tommy has made a conjecture about the sum of two Obtuse angles.
' The sum of two obtuse angles cannot be an obtuse angle'
Do you agree with Tommy?
explain your reasoning
Answers
I agree with Tommy because the sum of the smallest obtuse angles (91+91⁰) is 182⁰ which is a reflex angle, not obtuse. The other obtuse angles will be bigger and so will not be obtuse either.

Using midline interval, the value of ML is 58.
What is midline interval?
The distance from the "midline of the interval to either end line is called midline interval".
According to the question,
The line JK is 3x+11, the line ML is 10x - 12. In order to find the value of ML.
The formula to calculate value of ML is midline value = [tex]\frac{(x1 + x2)}{2}[/tex].
Let x₁ = 3x + 11 and x₂ = 10x - 12
45 = [tex]\frac{(3x + 11) + (10x - 12 )}{2}[/tex]
90 = 3x + 11 + 10x -12
= 13x -1
13x = 91
x = 7
Substitute x = 7, in equation x₂ we get 10(7) - 12 = 70 - 12 = 58.
Hence, using midline interval the value of ML is 58.

When ringing up a customer, a cashier needs 7 seconds to process payment as well as 1.5 seconds to scan each item being purchased. If it takes 28 second s to ring up a customer ,how many items are being purchased?
Answers
Answer:
14 items
Step-by-step explanation:
What we know:
- it takes 7 seconds to process the payment
- for every item, it takes 1.5 seconds to scan
- in total, it took 28 seconds to ring up the customer
With these pieces of information, we can construct the following equation:
[tex]28=1.5x+7[/tex] when [tex]x[/tex] is equal to the number of items there is
Subtract both sides by 7
[tex]28-7=1.5x+7-7\\21=1.5x[/tex]
Divide both sides by 1.5
[tex]\frac{21}{1.5} =\frac{1.5x}{1.5} \\14=x[/tex]
Therefore, 14 items were being purchased.

Combine like terms:

Divide by 10:
x = 3
Plug x back in to solve for y:
2(3) - y = 10
6 - y = 10
Subtract 6:
-y = 4
Divide by -1:
y = -4
So your solution is x = 3 and y = -4 which is also written as (3, -4).

Ten students from a class participated in a math quiz. The scores obtained by
them were recorded as follows.
11, 6, 7, 13, 1, 13, 16, 7, 13, 16
Mean :
Median :
Mode :
Range :
Answers
Answer:
Mean: 10.3
Median: 12
Mode: 13
Range: 15
Step-by-step explanation:
First, let's define what all these terms mean.
Mean is the average of all the numbers in a set of data. Median is the number in the middle of a range whenever the numbers are put in ascending order. If there are two numbers in the middle instead of one, then take the average of those two numbers. Mode is the number that occurs the most in the set of data. Range is the difference between the largest and the smallest number in a set of data.
To make things a little easier overall, let's just go ahead and put all our numbers in ascending order, which will be as follows: 1, 6, 7, 7, 11, 13, 13, 13, 16, 16.
To find the mean, just add up all the numbers and divide by how many there are. So we'll add 1 + 6 + 7 + 7... and so on to get a total of 103. Next, we'll divide that number by 10 since there are 10 students. This gives us a mean of 10.3.
Next, we'll find the median. To find this, just figure out which number(s) is in the center of your data. Since we have an even number of terms (10), we'll have two numbers in the middle, being 11 and 13. To find our median from here, just add 11 and 13 and then divide by 2. 11 + 13 = 24 and then 24 / 2 = 12. This means that our median is 12.
Next, we'll find the mode. The mode is the number that is seen the most in a set of numbers. In our set, we see that there are three 13s. Since 13 is the most frequently used number in our set, this makes it the mode.
Finally, we'll find the range. The range is just the largest number in the set minus the smallest number in the set. In our set, 16 is our largest number and 1 is our smallest. Just do 16 - 1 = 15 and we'll see that 15 is the range of the set. Hope this helps!

In t years after 2019 there are going to be 39,523,462*(1.172)^t people.
Step-by-step explanation:
For a) We have a starting amount of 39,523,462 people in 2019, if each year it grows at a rate if 1.72% then 1 year after 2019 would have 39,523,462*1.172 people. In 2 years we would have 39,523,462*1.172*1.172 or 39,523,462*1.172^2 people etc. We could conclude that after t years there would be 39,523,462*1.172^t people. In part b) just calculate this when t=11 and round this to the nearest whole number, I think you can do it yourself.
write an equation of the line that passes through (2, -4) and (0, -4)
Answers
(2, -4) means 2 is your x1 and -4 is your y1
(0, -4) means 0 is your x2 and -4 is your y2
(y2-y1) = -4 - (-4) = -4 + 4 = 0
(x2-x1) = 0 - 2 = -2
0/-2 = slope of 0
Plug slope and one point into point-slope formula y-y1 = m(x - x1)
y - (-4) = 0(x - 0)
y + 4 = 0
y = -4
You have a horizontal line going through the point (0, -4)
