With two points you can define a line.
So, the line parallel to s is q, which has these two pointS: (3,6) and (6,3)
There are different ways to get the line. For instance, this one:
Y = a*x+b
a = slope = difference_y/difference_x = (3-6)/(6-3) = -1,
y = -x + b,
Now use any point, say (3,6) to get b:
6 = -3+b-> b - 9.
Line is y = -x + 9,
It checks out in the other point: (6,3) —> 3 = -6+9 = 3. Good.
Other method:
y-y2 = a*(x-x2), where (x2,y2) is one of the two points and a is the slope as defined before.
Really hope this helped you!

Given the lengths of two sides of a triangle, find the range for the length of the third side. (Range means find between which two numbers the length of the third side must fall.) Write an inequality. 22 and 15
Answer:
7 < (third side length) < 37
Step-by-step explanation:
Add these two side lengths together. We get 37. Unless the 3rd side is LESS than 37, we cannot form a triangle.
Next, subtract 15 from 22, obtaining 7. The 3rd side has to be GREATER than 7 in order for the sides 7+, 15 and 22 to form a triangle.
7 < (third side length) < 37

Which expression can be used to find the surface area of the following triangular prism? And stop reporting my question!
Answer:
S.A=132
Step-by-step explanation:
A=[[tex]\frac{1}{2}[/tex] x b x h]2
A=[tex]\frac{1}{2}[/tex] x 4 x 3 x 2 12+50+40+30=132
A=12 cm²
A=L x W
A=10 x 5=50
A=L X W
A=10 X 4=40
A=L X W
A=10 X 3=30
Each triangular end has a surface area of (1/2)(base)(height), which in this case is (1/2)(4)(3), or 6 units^2. There are two ends, so the total area of the ends is 12 units^2. The three remaining sides account for the surface area
(4)(10) + (5)(10) + 3(10). or 120.
The sum of the surface areas of all five areas is 120 + 12 units^2, or 132 units^2
.Answer:
132 units^2

Answer:
it is d
Step-by-step explanation:
it is because d has more parts so it would land on it more then yellow and have a higher chance to land on blue
hope this helps
Answer:
C is the most reasonable.
Step-by-step explanation:
So we can put it in a ratio of 4:3:1. Then add all those up and do 240/8 which is 30. So each number in the ratio is 30. Then we do 4*30=120. 3*30=90. 1*30=30. Both red and blue are close to there answers but red is closer.

Question 2 Answer: (2, -2) y= 2 - 2x
Step-by-step explanation:
Question 1 explanation: Solve the first equation for y.
3 = 4x + y
3 − 4x = y Subtract 4x from both sides.
y = 3 − 4x Rewrite the equation.
Simplify the second equation by dividing.
2y = 6 − 8x
y = 3 − 4x Divide both sides of the second equation by 2.
Rewrite the system.
y = 3 − 4x
y = 3 − 4x
Which expression can be used to find the surface area of the following square pyramid?
Answer:
4[1/2(5 x 6)] + 6x6
Step-by-step explanation:
The first part of the expression is 4[1/2(5 x 6)]. This is the formula to find the surface area of the triangles. A regular triangle's area is 1/2(l*w). Since there are four trinagles, you have to multiply the whole expression by 4.
The second part of the equation is finding the surface area of the base which is a square. Since squares have four equal sides, its safe to say that you can use 6 * 6.

A pharmacist is filling small empty bottles with cough syrup from a larger bottle. He can solve the inequality to find the number of small bottles, x, that can be filled from the larger bottle and still have 250 milliliters left in the larger bottle. Which statement describes the number of small bottles the pharmacist can fill?×
Answer:
1000 -25x >250.
Step-by-step explanation:
Let us assume the capacity of a large bottle = 1000 ml.
And the capacity of each small bottle = 25 ml.
Reaming milliliters in large bottles = 250 milliliters.
Number of bottles = x bottles.
The total capacity of the large bottle - capacity of a small bottle × number of bottles > Remaining milliliters in a large bottle.
Therefore, we can set up an inequality.
1000 - 25 × x > 250.
1000 -25x >250.
PLEASE HELP The number of bagels sold daily for two bakeries is shown in the table: Based on these data, is it better to describe the centers of distribution in terms of the mean or the median? Explain. 1 Mean for both bakeries because the data is symmetric 2Mean for Bakery B because the data is symmetric; median for Bakery A because the data is not symmetric 3 Mean for Bakery A because the data is symmetric; median for Bakery B because the data is not symmetric 4 Median for both bakeries because the data is not symmetric
Answer:
4
Step-by-step explanation:
its unclear what the standard for "symmetric" is though both data points have large and small numbers ranging from the 10-40+ thus, the data range is large and the mean will not accurately represent the data well. Thus median would be best

From the figure the correct options are ΔABC ~ ΔDEC, ∠B ≅ ∠E, 3DE = 2AB.
Given that a right triangle ΔABC is being dilated by a scale factor of 2/3 and reflected over the side AC to form the ΔDEF.
Since we know that in reflection transformations the object are similar so we can conclude that ΔABC ~ ΔDEC.
Also, by the definition of similar triangles,
∠B ≅ ∠E, ∠A ≅ ∠D and ∠ACB ≅ ∠DCE.
Now since the scale factor is 2/3,
so,
2AB = 3DE
2BC = 3CE
2AC = 3DC
Hence the correct options are ΔABC ~ ΔDEC, ∠B ≅ ∠E, 3DE = 2AB.

The graph shows a journey in a car. Which of the statements most likely describes the journey back to the starting point at the the portion of the graph labeled O?
Answer:
The car travels different distance per unit of time.
Step-by-step explanation:
Distance per unit time on graph will be = Distance for a given point time/ Time
if we see this in terms of x and y , it will be the slope of the curve on given graph.
y/x = slope of graph
Now solving it becomes easier.
We know that
slope = [tex]tan\alpha[/tex] where [tex]\alpha[/tex] is the positive angle with x axis
For part I
The slope will be tan of some acute angle and we know that
tan of acute angle varies between 0 to 1.
Distance per unit time on graph will be between 0 to 1
for part J
Line is parallel to x axis and hence angle with x axis will be 0
thus,
tan 0 = 0
slope of part j is 0
Distance per unit time on graph will be = 0
For part k the distance is changing at each point hence we have to find
distance for each point and time for each point on coordinate and hence
Distance per unit time on graph for part k will be different at each point.
part L and N can be explained on similar grounds as J
O can be explained by explanation for part K.
Part M can be explained by explanation of part I
here difference will be that slope is obtuse and hence
slope or distance per unit time will be negative
as tan for obtuse angle is between -1 to 0.
Thus, correct option will be
The car travels different distance per unit of time.

Select one:
Answer:
y=8/3x-34/3
Step-by-step explanation: If the line is parallel to y=8/3x+7, then the slope must be 8/3. So, we can eliminate A and B. Now, let's take C, and plug in (8, 10) into the equation. We end up with 10=64/3-34/3. 64-34=30. 30/3=10. 10 = 10. So, C is the correct answer. No need to check for D.

Which is a correct step to solve the equation 1=−4+3/8x
A.4(1)=4(−4+3/8x)
B.1=8(−4+3/8x)
C.8(1)=8(−4+3/8x)
D.3(1)=3(−4+3/8x
Can someone please help me
Answer:
C. 8(1)=8(−4+3/8x)
Step-by-step explanation:
Given equation
1=−4+3/8x
in this equation in denominator we have 8x,
since we are solving for x we cannot eliminate it, but we have to eliminate 8 in denominator, so that there only numerator in equation and solving process becomes easier.
To eliminate 8,we need to multiply both side by 8, so as to balance the equation and also 8 from denominator gets cancelled in RHS.
1=−4+3/8x
multiply both side by 8
8(1)=8(−4+3/8x)
Thus, option c is correct one
8(1)=8(−4+3/8x)
solving it
8 = -32 + 3/x
adding both side 32
8+32 = -32 + 3/x -32
=> 40 = 3/x
=> x = 3/40
Anton bought a picnic cooler. His total bill, with tax, was $7.95.
He paid 6 percent sales tax. How much did he pay for the cooler
alone without the tax?
Answer:
$ 7.50
Step-by-step explanation:
The cost of the picnic cooler would be 100%.
With the 6% sales tax, Anton would pay 106% of the cost if the picnic cooler.
(since 100% +6%= 106%)
106%(picnic cooler)= $7.95
Cost of picnic cooler= 100%(picnic cooler).
Cost of picnic cooler
[tex] = \frac{7.95}{106} \times 100 \\ = 7.50[/tex]
Thus, he paid $7.50 for the cooler alone.

Required
Relative frequency of respondents who are Republican
First we consider the data in the republican row; this is presented as follows;
