Answer: -1/2

Step-by-step explanation:

You want to find the equation for a line that passes through the points.

We use formula y2-y1/x2-x1

5-3/-2-2 = 2/-4

= -1/2

Write an equation for a like that is parallel to the given point. Explain how you found the equation.
pishuonlain [190]

Answer:

The line would be y = 2x + 5

Step-by-step explanation:

To find a parallel line, we first need to note that the slope of the original line is 2. This means the slope of our new line will also be 2 because parallel lines have the same slope.

So we use the slope we found along with the point given in point-slope form. Then we solve for y.

y - y1 = m(x - x1)

y - 11 = 2(x - 3)

y - 11 = 2x - 6

y = 2x + 5

Carla bought a piece of ribbon that measured 1 meter in length. She used 1/4 of the ribbon on a gift box. She used 1/8 of the ri
lord [1]

1/4 is equal to 2/8.

2/8+1/8=3/8

Carla used 3/8 of the ribbon in all. So, 5/8 of the ribbon is left.

I hope this helps :)

Simplify each expression. Then state the coefficient of the variable in each expression. 1. U + u + u + u
Pani-rosa [81]

Answer:

  • 4u
  • the coefficient is 4

Step-by-step explanation:

Using the distributive property, we can write the expression as ...

  (1 + 1 + 1 + 1)u = 4u

The coefficient of the variable is 4 in the simplified expression.

The freezing point of water, T (measured in degrees Fahrenheit), at altitude a (measured in feet) is modeled by the function T(a
ycow [4]

Answer:

<em>The freezing point of water increases by 0.0001 degrees Fahrenheit when the altitude increases by 1 foot.</em>

Step-by-step explanation:

The model for the freezing point of water T at altitude a is:

T(a)= 0.0001a+32

The slope of this equation is the coefficient of the variable a. Since the slope is positive, it means the freezing point of water increases by 0.0001 degrees Fahrenheit when the altitude increases by 1 foot.

For example, when a=1000, the freezing point is:

T(1000)= 0.0001*1000+32 = 32.1°F

When a=1001, the freezing point is:

T(1001)= 0.0001*1001+32 = 32.1001°F

Note the increase of 1 foot in altitued meant an increase of 32.1001-32.1 = 0.0001°F
