For m^3 : Because you are subtracting a negative from a negative, that means you are adding, therefore the first part should be 7m^3

For m^2 : because you are subtracting a positive from a negative, that means you are subtracting, so it would be -11m^2

For m : because you are subtracting a negative from zero, it would turn into a positive, making it just 5

For the constant : subtracting positive 8 from negative 9 makes it a positive from the double negative. Therefore you would add 8+9, giving you 17

FINAL ANSWER : B. (7m^3)-(11m^2)+5m+17

What is the slope for this table?

sdas [7]

<h3>Answer: Slope = -3</h3>

=======================================================

Explanation:

Pick any two rows you want. I'll pick the middle two rows where every value is positive. So I'll pick these two rows:

x = 0 and y = 4
x = 1 and y = 1

They lead to the points (0,4) and (1,1). Apply the slope formula for these rows.

m = (y2-y1)/(x2-x1)

m = (1-4)/(1-0)

m = -3/1

m = -3

The slope is -3

ΔEFI is dilated by a scale factor of one third with the center of dilation at point F. Then, it is reflected over line a to crea

timofeeve [1]

Answer:

The correct option is;

Segment FE over 3 = Segment FH

Segment FI over 3 = Segment FG, and

Segment EI over 3 = Segment HG

ΔEFI ~ ΔHFG

Step-by-step explanation:

The given transformations are'

ΔEFI is dilated by a scale factor of 1/3 and then it is reflected over line a

By dilation, we have

FH = 1/3×FE

FG = 1/3×FI

HG = 1/3×EI

Also by reflection over a line, the relative positions of the y-coordinates of the points remain the same while the x coordinates changes sign such that an upright mirror image of the dilated triangle is formed

Therefore, since we have;

$\dfrac{sin\alpha}{sin\beta } \ and \ \dfrac{sin\gamma}{sin\alpha }$ the same for both triangles, that is given the following relation;

FG/FH = (1/3×FI)/(1/3×FE) = FI/FE

Then, ΔEFI is similar to ΔHFG (triangle similarity requirement AAA)

Hence, the correct option is that the

Segment FE over 3 = Segment FH

Segment FI over 3 = Segment FG, and

Segment EI over 3 = Segment HG

ΔEFI ~ ΔHFG.

Given Arc KM measures 130 degrees, what is the measure of angle MLK?

photoshop1234 [79]

Answer:

m<MLK = 65°

Step-by-step explanation:

Measure of intercepted arc KM = 130°

<MLK is the inscribed angle of the intercepted arc.

Therefore, measure of inscribed angle = ½ the measure of its intercepted arc.

Thus:

m<MLK = ½(130)

m<MLK = 65°
