Answers

Answer: C. (2, -5 )

Step-by-step explanation:

These are the coordinates of the points on the line

We can see (-3, 5) and (0, -1) on the line.

To find the y-coordinate of a point when the x-coordinate is 2, all you have to do is look for the x-intercept of 2 and look for the y-intercept.

When you look at the bottom of the graph, you can see that the x-coordinate 2 and the y-coordinate -5 intersect to form a point.

Answer:

y=6x+4

Step-by-step explanation:

now the formula for slope-intercept is y=mx+b

Slope (aka m) is 6

[how I got the slope is every time it goes forward 1 it goes up 6  rise/run]

so y=6x+[y intercept]

the y intercept is 4 as seen in the chart so:

y=6x+4

Step-by-step explanation: 200 times 2.80 is 560,

5% of 560 is 588,

150% of 588 is 882,

and then 882 divided by 200 is 4.18 (or 4.19)

Wilbur was training for a race that was 6 1/4 miles long. He could only run 1 1/4 miles before needing to stop to take a break. How many times will Wilbur need to take a break during his run?

Please help

Answers

Answer:7 2/4

Alright let’s go step by step for this:

1.) 6 1/4 - 1 1/4 = 5

2.) If he can run 1 1/4 miles before needing a break you would have to divide that number into the subtracted number from above

5 ÷ 1 1/4

5 ÷ 1.25

4.) Then divide

Which transformations were used to create a triangle JKL

Answers

The second one because the triangle prime is much smaller than the green one. And the reflection is towards the x axis

The transformation used to create K'L'M' would be, dilation by a scale factor 1/2 and reflection across the x-axis.

What is transformation?

"Transformations are change in the original shapes on a coordinate plane by rotation, reflection or translation. "

What is reflection transformation?

"It is a transformation which produces mirror image of geometrical structure."

What is dilation?

"It is a transformation in which size of the geometrical structure is changed without changing its shape."

From given diagram,

we can observe that JK = 4 and J'K' = 2

This means the size of the triangle J'K'L' is reduced by 1/2

Also, it is reflected along x-axis.

This means, the transformation used to create triangle K'L'M' would be, dilation by a scale factor 1/2 and reflection across the x-axis.

Therefore, the correct answer is option (B).
