Answer:
ans of problem 12 is:
x=65
y=10
Answer:
Step-by-step explanation:
Problem 12:
I think that (2x-y)+60=(2x+y)+40
Because of the Alternate Interior Angles theorem, which places the 40 next to (2x+y) so then you know they are a linear pair. Same can be done for the side with the 60 degree angle. So both sides add up to 180 so they are congruent themselves and you can put them in this format:
(2x-y)+60=(2x+y)+40
-40 -40
We do this to remove the 40 from the right side completely, and whatever you do to one side of the equation you have to do to the other as well so remove 40 from both.
(2x-y)+20=(2x+y)
-2x -2x
Again, we are just trying to find out y right now
-y +20=y
+y +y
20 = 2y
10 = y
Then insert the y into an equation telling us that it is equal to 180 (because we know that from before) to get what x is
(2x-y)+60=180
We can also input our y that we found out was 10 from before:
(2x-10)+60=180
And now we can add up 60 and -10
2x+50=180
Now subtract 50 to both sides
2x=130
And divide both sides by 2
x=75
So x=75 and y=10

Problem 13:
The same type of working out, just with different numbers
What is the value of the expression below when y = 5?
10y + 6
I don’t understand this at all
Answer:
56
Step-by-step explanation:
10y+6
10(5)+6
10*5=50
50+6=56
Answer:
Basically, you need to plug 5 in as y
Step-by-step explanation:
First, plug 5 in the place of Y 10 * 5 + 6
Then solve the equation from there.
10 * 5 = 50
50 + 6 = 56

How do I turn something like this: 3x - 2y = -16
Into a slope-intercept form?
(Whoever can explain gets Brainliest) (UwU)
[tex]3x - 2y = - 16[/tex]
Subtract sides -3x
[tex]3x - 3x - 2y = - 3x - 16[/tex]
Simplification
[tex] - 2y = - 3x - 16[/tex]
Negatives simplifies
[tex]2y = 3x + 16[/tex]
Divided sides by 2
[tex] \frac{2y}{2} = \frac{3x + 16}{2} \\ [/tex]
[tex] \frac{2}{2}y = \frac{3}{2}x + \frac{16}{2} \\ [/tex]
Simplification
[tex]y = \frac{3}{2}x + 8 \\ [/tex]
This is the slope-intercept form.

Jacob received 685 votes in the school election.
If he received 125 more than 2/3 of the total
number of votes, how many students voted in
the election?
Answer:
840
Step-by-step explanation:
He gets 685 votes. This is 125 more than 2/3 of the total number of votes. So 2/3 must be 125 less than 685.
2/3=560
So ÷2 to find 1/3, because 2/3 ÷2 = 1/3.
1/3=280
So then you x3 because 1/3x3=3/3, or 1 whole.
1 whole=840
840=total number of votes
Find the value of x in each case:
L, M ∈ KN
Answer:
x = 27
Step-by-step explanation:
From the picture attached,
m∠PLM + m∠PLK = 180° [Linear pair of angles are supplementary]
m∠PLM + 3x = 180°
m∠PLM = 180° - 3x
Similarly, m∠PML + m∠PMN = 180° [Linear pair of angles]
m∠PML + (2x + 72)° = 180°
m∠PML = 180° - (2x + 72)°
From triangle PLM.
m∠PLM + m∠PML + m∠LPM = 180° [Sum of interior angles of a triangle = 180°]
(180 - 3x) + 180 - (2x + 72) + x = 180
180 - 3x - 2x - 72 + x = 0
-4x + 108 = 0
x = [tex]\frac{108}{4}[/tex]

Theequationforlinegcanbewrittenas y = –9 4 x − 1 . Line h , whichisperpendiculartoline g , includesthepoint (10, 4) . What istheequationofline h ? Write the equation in slope-intercept form. Write the numbers in the equation as proper fractions, improper fractions, or integers.
Answer:
y-4 = 4/9(x-10)
Step-by-step explanation:
Given the equation of the line g to be y = -9/4 x - 1.
To find the equation of a line h perpendicular to this line, the following steps must be taken;
First find the slope of the known line g
The standard equation of a line is y = mx+c where
m is the slope
c is the intercept
Comparing this equation with the given equation y = -9/4 x -1, it can be seen that the slope of the line g is -9/4
Next is to find the slope of the line h
Since the line g is perpendicular to h, then the product of their slope will be -1 i.e mh*mg = -1
mh = -1.mg
mh = -1/(-9/4)
mh = -1*-4/9
mh = 4/9
Hence the slope of the line h is 4/9
Find the intercept of line h
To get this, you will substitute the slope m and the point into the equation y = mx+c
m = 4/9
(x,y) = (10,4)
4 = 4/9(10) + c
4 = 40/9 + c
c = 4-40/9
c = (36-40)/9
c = -4/9
Hence the intercept of the line h is -4/9
Finally, find the equation of the line h in slope-intercept form
The slope-intercept form of a line is expressed as y = mx+c
y-y0 = m(x-x0)
Given
m = -4/9
x0 = 10
y0 = 4
Substitute:
y-4 = 4/9(x-10)
Hence the equation in slope-intercept form is y-4 = 4/9(x-10)
9(m +5) - 3(m - 2) = 8m + 31
Answer:
m=10
Step-by-step explanation:
Answer:
m=10
Step-by-step explanation:
9(m+5)−3(m−2)=8m+31
Step 1: Simplify both sides of the equation.
9(m+5)−3(m−2)=8m+31
9m+45+−3m+6=8m+31
(9m+−3m)+(45+6)=8m+31(Combine Like Terms)
6m+51=8m+31
Step 2: Subtract 8m from both sides.
6m+51−8m=8m+31−8m
−2m+51=31
Step 3: Subtract 51 from both sides.
−2m+51−51=31−51
−2m=−20
Step 4: Divide both sides by -2.
m=10

C) arm span and foot length are predicted to increase by about 0.186 cm.
What is linear regression?Linear regression analysis is used to predict the value of a variable based on the value of another variable. The variable you want to predict is called the dependent variable. The variable you are using to predict the other variable's value is called the independent variable.
Given, The arm span and foot length were measured (in centimeters) for each of the 19 students in a statistics class and displayed in the scatterplot.
let "FL" be the foot length and "AS" be the Arm span.
Slope = Δy/Δx = ΔFL/ΔAS
ΔFL/ΔAS = 0.186
ΔFL = ΔAS* 0.186
thus an increase in AS by 1 cm will lead to an increase in FL by 0.186cm
Therefore, the slope of the least-squares regression line means for each additional centimeter C) arm span, foot length is predicted to increase by about 0.186 cm.
