What is the equation of aline that passes through the point (4,-8) and has a slope of -1/2?
viktelen [127]

Answer:

The equation of the line will be:

y=-\frac{1}{2}x-6

Step-by-step explanation:

Given

  • slope = m = -1/2
  • point (4, -8)

Point slope form:

y-y_1=m\left(x-x_1\right)

substituting the values m = -1/2 and the point (4,-8)

y-\left(-8\right)=\frac{-1}{2}\left(x-4\right)

y+8=\frac{-1}{2}\left(x-4\right)

subtract 8 from both sides

y+8-8=\frac{-1}{2}\left(x-4\right)-8

y=-\frac{1}{2}x-6

Therefore, the equation of the line will be:

y=-\frac{1}{2}x-6

Which of the following uses estimation to check 267 - 154 = 113
mamaluj [8]
Answer: it is the third but there is a typo. It is C. 267 - 150 = 117

Explanation:

You can do that estimation searching to make a quick verification, because adding rounding 154 to the tens leads to 150 and it is very easy to subtract 267 - 150 instead of 267 - 154, driving to a quick approximate check of the subtraction.

Rob laid three sticks end to end. The lengths of the sticks were 45 millimeters, 32 centimeters, and 4 decimeters. How long, in
Oksanka [162]

Answer:

<u>0.765 meters</u> long were the sticks when laid end to end.

Step-by-step explanation:

Given:

Rob laid three sticks end to end. The lengths of the sticks were 45 millimeters, 32 centimeters, and 4 decimeters.

Now, to find the length in meters of the sticks when laid end to end.

The lengths of the sticks are:

1st stick - 45 millimeters.

2nd stick - 32 centimeters.

3rd stick - 4 decimeters.

So, we convert the units of sticks into meters by using conversion factor:

1st stick:

1 millimeter = 0.001 meter.

45 millimeters = 0.001 × 45

45 millimeters = 0.045 meter.

2nd stick:

1 centimeter = 0.01 meter.

32 centimeters = 0.01 × 32

32 centimeters = 0.32 meter.

3rd stick:

1 decimeter = 0.1 meter.

4 decimeters = 0.1 × 4

4 decimeters = 0.4 meter.

Now, adding all the three sticks length to get the the length in meters of the sticks when laid end to end:

0.045+0.32+0.4\\\\=0.765\ meters.

Therefore, 0.765 meters long were the sticks when laid end to end.

(-b3+ 3b2 + 8) - (? - 5b2 - 9) = 5b3 + 8b2 + 17<br> ? =<br> DONE
zhuklara [117]

Let's solve for x.

−b3+3b2+8−(x−5b2−9)=5b3+8b2+17

Step 1: Add b^3 to both sides.

−b3+8b2−x+17+b3=5b3+8b2+17+b3

8b2−x+17=6b3+8b2+17

Step 2: Add -8b^2 to both sides.

8b2−x+17+−8b2=6b3+8b2+17+−8b2

−x+17=6b3+17

Step 3: Add -17 to both sides.

−x+17+−17=6b3+17+−17

−x=6b3

Step 4: Divide both sides by -1.

−x

−1

=

6b3

−1

x=−6b3

Answer:

x=−6b3
