Answer:
1. parallel
2. no solutions
Step-by-step explanation:
You can prove the lines are parallel because they never intersect, as they have the same slope.
Thus, parallel lines have no solutions.
* a solution is the point (x,y) where 2 or more functions intersect
IF THIS RESPONSE HELPED YOU, PLEASE MARK IT THE "BRAINLIEST"! :)
Step-by-step explanation:
checking the slope of both lines :
red goes through (2, 1) and (4, 5)
blue goes through (-2, 0) and (0, 4).
the slope is the ratio
(y coordinate difference / x coordinate difference)
when going from one point on the line to another.
for the red slope and the identified points
x changes by +2 (from 2 to 4).
y changes by +4 (from 1 to 5).
the slope is +4/+2 = 2
for the blue slope and the identified points
x changes by +2 (from -2 to 0).
y changes by +4 (from 0 to 4).
the slope is +4/+2 = 2.
so, both lines have the same slope and are therefore parallel.
parallel lines that are not identical have no solution, as they have no intersection point.
so,
parallel
no solution

Your final grade in a class is based on your score on two tests and the final exam. You scored a 74% and 82% on the tests and an 80% on the final exam
Answers
The average grade received on two tests and the final exam is 78.67%
What is average?
The ratio of the sum of the values in a particular set to all the values in the set is the mean value, which is the definition of the average.
The average formula has numerous practical uses. If we were asked to determine the average male height in India or the average age of the men and women in a group, we would add up all the data and divide it by the total number of data points.
Given, the grades in tests are 74% and 82%. Also, the grade on final exam is 80%.
Now, considering that we have to find the average grade in tests and final exams combined, we put the average formula.
Average grade = Sum of percentages of each exam/Total exams
Thus, average is
= (74+82+80)%/3
= 236%/3
= 78.67%
The average grade received on two tests and the final exam is 78.67%.

Answers
Answer:
125+25n
Step-by-step explanation:
We are given that
Heather opens a bank account with=$125
Each week she deposited money into her account=$25
We have to find the explicit rule for the amount of money that has Heather after n weeks.
Heather has money after 1 week=125+25=$150
Heather has money after 2 week=125+2(25)=$175
Heather has money after 3 weeks=125+3(25)=$200
Heather has money after n weeks=125+25(n)
Hence, the explicit rule for the amount of money that has Heather after n weeks is given by

The poster above has good diagrams ; so , I will just go through the calculations .
The region of integration is with in the circle x ^2+y^2=2y but outside the circle x^2+y^2=1.
I would convert to polar . With polar , we have x^2+y^2=r^2 ,x=rcosФ and y=rsinФ
We thus have the first circle becomes x^2+y^2=2y ⇒r^2=2rsinФ Divide through by r, and you get r=2sinФ(1).
This is the upper circle in the previous posters diagrams .
The other equation of a circle becomes :
x^2 + y^2 = 1 ⇒ r^2 = 1 ⇒ r = 1 (2)
These two curves intersect at :
r= 2sinФ =1 ⇒ sinФ=1/2 ⇒Ф= [tex]\alpha[/tex]/6 or 5[tex]\pi[/tex]/6
From the previous poster's diagrams , we can see that there is as much mass on either side of the positive. y axis or

How to find the vertical asymptote of a function?A vertical asymptote of a graph is defined as a vertical line x = a where the graph tends toward positive or negative infinity as the inputs approach a.
A vertical asymptote is a value of x for which the function is not defined, that is, it is a point which is outside the domain of a function;
In a graph, these vertical asymptotes are given by dashed vertical lines.
An example is a value of x for which the denominator of the function is 0, and the function approaches infinity for these values of x.
We are given the function;
g(x) = 2(x + 4)²/(x² - 16)
Simplifying the denominator gives;
(x² - 16) = (x + 4)(x - 4)
Thus, our function is;
g(x) = 2(x + 4)²/[(x + 4)(x - 4)]
(x + 4 ) will cancel out to give;
g(x) = 2(x + 4)/(x - 4)

Find the value of the variables in the given parallelogram.
Answers
Answer:
x = 58, y = 61
Step-by-step explanation:
We can use two properties of a parallelogram to solve this
1. The opposite angles of a parallelogram are equal
2. The sum of the 4 interior angles of a parallelogram equal 360
Using property 1,
the angle opposite angle y is also y(bottom left)2x + 3 = y + xTherefore 2x -x - y = -3 or x - y = -3 [1]
Using property 2
(2x - 3) + y + (y + x) + y = 360
3x + 3y + 3 = 360
3x + 3y = 360 - 3 = 357
Divide both sides by 3 to get
x + y = 357/3
x + y = 119 [2]
Add [1] and [2] together to eliminate y and get
x - y + x + y = -3 + 119
2x = 116
x = 116/2 = 58
Use equation [2]
x + y = 119
58 + y = 119
y = 119 - 58
y = 61

If line BG and CF are parallel,then the supplement of BIE = the supplement of GMD. Is this statement correct? Explain your answers
Answers
The supplement of BIE equals the supplement of GMD is a false assertion if lines BG and CF are parallel.
Describe the supplement angle.Angles with a supplementary sum are those whose sum is 180 degrees. For instance, the total of angle 130° and angle 50° is 180°, hence they are supplementary angles.
Lines BG and CF are parallel, as shown in the figure.
If BIE = X, then its supplement of BIE will be 180 - X;
similarly, if GMD = Y, then its supplement of GMD will be 180 - Y.
Since BG and CF are parallel, the supplements of BIE and GMD are interior angles on the same side ( as shown in figure)
and for parallel line the interior angle on the same side is 180
so 180 - X and 180 -Y there sum should be 180
They cannot be equal
line BG and CF are parallel, then the supplement of BIE = the supplement of GMD are not equal.

You win an online auction for a toy. Your winning bid of $30 is 60% of your maximum bid. How much more were you willing to pay for the toy than you actually paid?
Answers
Answer:
I was willing to pay $20 more for the toy than I actually paid.
Step-by-step explanation:
Let us take the maximum bid be y
So,
(y × 60) ÷ 100 = 30
60y/100 = 30
60y/100 × 100 = 30 × 100
60y = 3000
60y/60 = 3000/60
y = 50
60% of $50 is $30
So,
50 - 30 = 20
Thus, I was willing to pay $20 more for the toy than I actually paid.

How to interpret Polynomial Graphs?In polynomial graphs, we know that the roots are the points where the graph crosses or touches the x-axis.
In this given graph, we see that the graph touches the x-axis at x = 5 and then crosses the x-axis at x = -2. Thus;
The roots of the equation are -2 and 5.
However, when the graph changes sign at a point on the x-axis, it means that point represents double roots. Thus, we will now have three roots which are -2, 5 and 5. The factors of the polynomial are;
(x + 2), (x - 5)²
Now, we see that when x = 0, y = 100 from the graph. Thus;
a(0 + 2)(0 - 5)² = 100
a(50) = 100
a = 100/50
a = 2
Thus, the equation would now be;
