Answer:
a straight line can be drawn through all the points and the lines passes through the point where x = 0 and y = 0 (the origin).
Step-by-step explanation:
in a proportional relationship, one variable is always a constant value times the other. That constant "a" is know as the "constant of proportionality".
y = ax
and as you can easily see, that implies if x = 0, then y = 0.
therefore, the given answer is correct.

Answer: 32ft²
Step-by-step explanation:
The area of a trapezoid is given by the formula: A = [(b1+b2)/2] x h, where b1 and b2 are the two bases, and h is the height.
In our situation, b1 = 3, and b2 = 5. The height is given as 2.
Plugging these numbers into our formula:
A = (b1+b2)/2 x h
A = [(3+5)/2] x 2
A = (8/2) x 2
A = 4 x 2
A = 8ft²
8ft² is the area of one trapezoid. If Mr. Smith wants to fit 4 of these shapes into the room, the combined area will be 4 x 8 = 32ft².

A 160-inch board is cut into two pieces. One piece is four times the length of the other. Find the length of the shorter piece.
PLEASE HELP
Let the shorter piece be x. The longer piece is 4 times the length of the other, so it is 4x.
4x + x = 160.
5x = 160
x = 32
4x = 128
The length of the shorter piece is x, which is 32.

Draw a graph of y = 8x. From the graph, find the value of y when x = 1 ...... I need it fast..pls I will mark brainliest.
Answer:
Solving steps:
find the value of y when x = 1
=> y = 8(1)
multiply 8 by 1
=> y = 8
Hey there!
ORIGINAL EQUATION: y = 8x
This one should be quite easy to answer because we already have the value of x. (x = 1) all we have to do is find the y-value and where it is on the number line.
NEW EQUATION: y = 8(1)

HELP PLS find measure of w in this trapezoid
Answer:
m<w= 36°
Step-by-step explanation:
Step 1) Applying geometric and algebraic knowledge, the two angles to the left are both 90, and equal to 180. If you add those two angles and the 146°, you will be given 326 in total.
90+90= 180 +146 = 326
Step 2) With knowledge that the sum of all interior angles inside of a quadrilateral add up to 360, subtract 326 from this.
360-326=36
Final product: m<w=36°

Turn y=1/2x + 3/2 into standard form
=============================================
Work Shown:
y = (1/2)x + 3/2
2y = x + 3 .... multiply every term by the LCD 2
2y-x = 3 ... subtract x from both sides
-x+2y = 3
x-2y = -3 ... multiply both sides by -1
The last step is done so that the x coefficient is positive
The equation is in the form Ax+By = C with
A = 1B = -2C = -3You could have your answer as -x+2y = 3, since that is also in standard form. But many math textbooks make A > 0.
4/7 divided by 2 1/3 = ???
Answer:
[tex]\frac{12}{49}[/tex]
explanation:
Use the keep change flip method. This consists of literally flipping a fraction to make the denominators alike, allowing for faster solves and multiplication.
[tex]2\frac{1}{3}[/tex] is [tex]\frac{7}{3}[/tex], so flip 7/3 so it is 3/7, matching up with 4/7.
Next, multiply.
4 x 3
7 x 7
4 x 3 is 12. Write 12 as a numerator.
7 x 7 is 49. Write 49 as a denominator.
Therefore, the answer is [tex]\frac{12}{49}[/tex]

What is the quotient. Of 25)9250
Answer:
370
Step-by-step explanation:
Isolate the numbers so that you are only dividing sections at a time.
So 25 goes in to 92 three times. so we multiply 25 by three and subtract that from 92. Put the three at the top and repeat throughout.
92-75=17
Bring the next number down and repeat.

The measure of angle Q is 70 degrees. Find the measure of angle P.
Answer:40
Step-by-step explanation: because 70 times 2 = 140 and you add 40 will equal 180 because every triangle equals 180
The measure of angle m<P is 40 degrees
The given triangle is an isosceles triangle where:
m<R = m<Q
Taking the sum of the interior angles, we will have:
m<P + ,m<Q + m<R = 180
70 + 70 + m<P = 180
m<P = 180 - 140
m<P= 40 degrees
Hence the measure of angle m<P is 40 degrees

Ben is traveling to Santa Cruz and needs a full tank of gas. A full tank of gas gives him a total of 260 miles until empty. So Ben goes to the gas station to fill up his tank but he only has $11.86. If $11.86 only gives Ben a total of 60 miles until empty, how much money does he need in all, to get a full tank of gas to drive to Santa Cruz? Round your answer to the nearest dollar. ?
260 miles / 60 miles = 4 1/3
He would need 4 1/3 more gas:
11.86 x 4 1/3 = 51.39
he would need $51.39

Are the lines y=0 and x=0 parallel?
Answer:
No, these equations are not parallel.
Step-by-step explanation:
The equation [tex]y=0[/tex] is a vertical line. This equation, in fact, is the y-axis.
The equation [tex]x=0[/tex] is a horizontal line. This equation, in fact, is the x-axis.
These lines are perpendicular, not parallel.
Does the relation in the table represent direct variation, inverse variation, or neither? If it is direct or inverse variation, write an equation to represent the relation. Explain your answer.
Answer:
Indirect variation
Step-by-step explanation:
If two variables change in inverse proportion, then it is called indirect variation.
xy = k where k is a constant.
5*2 = 10
10*1 =10
[tex]15*\dfrac{2}{3}=5*2=10\\\\\\20*\dfrac{1}{2}=10[/tex]
So, this is indirect variation.

Individuals of the same approximate weight running 6 mph or 1 mile every ten minutes have a calorie use factor of 62% of their weight; i.E., calories burned = (weight)(0.62). If they run an 8-minute mile, the factor is 65%. A man weighs 180 lb. He jogs a mile in 8 minutes. How many calories has he used up?
Answer: He has used up 117 calories.
Step-by-step explanation:
Given, For 62% as factor, calories burned (E)= (weight)(0.62).
Also, if they run an 8-minute mile, the factor is 65%. [given]
Then, calories burned (E)= (weight)(0.65). [65%=0.65]
Weight of man = 180 lb
Then, calories burned (E)= 180 x (0.65).
= 117
Thus , he burned 117 calories.
So, he has used up 117 calories.
