Answer:
y = 3
Step-by-step explanation:
If the line needs to be parallel to the x axis, it must be Horizontal. The formula for lines like this is y= mx+c with m being the gradient. With a horizontal line, the gradient is 0 and therefore we get y=c.
To find c, we need to find the y intersect which is where the line passes through the y axis. Since it is horizontal and passes through the dot, we can find that c = 3 as the dot is at 3 on the vertical axis.
From this, we can see that the equation is y = 3.
Answer:
3
Step-by-step explanation:
the x-axis is horizontal and the numbers above and below it are 4 and 2 and the dot was right on the line so it was 3

If Tristan wants to stretch the spring by 9 inches, how many kilograms of weight must he apply to it?
Answer:
Step-by-step explanation:
Substitute y = 9 into the equation y = 3x, or locate the answer on the graph:
y = 3x
9 = 3x.
Divide both sides of the equation by 3:
[tex]\frac{9}{3}[/tex] = [tex]\frac{3x}{3}[/tex]
3 = x
The spring stretches 9 inches with 3 kilograms of weight attached to it.

help me find what 8/9
Answer: B= 8÷9
I found this answer because if you divide 8 and 9 the 8 stays the same and the 9 turns into 1/9 and if you multiply 8 × 1/9 you will get 8/9.
I hope this helps! :)
Hey there!
To find the answer to a fraction to convert it to a decimal you have to DIVIDE to NUMERATOR (the TOP number) from the DENOMINATOR (the BOTTOM number) and it should give you your result to this given question
Option A doesn’t have anything to do with 8/9 because the question isn’t asking what is equivalent to eight divided one-ninths.
Option B. could possibly be your answer because it is asking what is equivalent to 8/9
Option C. also doesn’t have anything to do with 8/9 because the question isn’t asking what it is equivalent to nine divided one-eighths. 9 1/8 =
Option D. as well doesn’t have to do with 8/9 because the equation isn’t 9/8 so you can’t divided 9 from 8
Based on the information we have now. We can answer the question.
Possible answer: Option B. 8 ÷ 9

The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 6 , then
sum = 180° × 4 = 720°
Sum the interior angles and equate to 720
140 + 150 + 90 + x + 130 + 90 = 720 , that is
x + 600 = 720 ( subtract 600 from both sides )
x = 120

A hockey team plays 42 matches. It wins 21, draws 14 and loses the rest. Express each of these results as a percentage of the total number of games played.
Express the number of each result as a fraction of the total number of games played and multiply with 100.
The percentage of the games won is :21/42 × 100 = 50%The percentage of the draw games is :14/42 × 100 = 100/3 = 33 1/3%The percentage of the games lost is :42-21-14/42 × 100 = 7/42 × 100 = 50/3 = 16 2/3%
