What is the slope intercept form when m = 1/2 & b = 89 ?
Helppppppppp

Answers

Answer:

[tex]y = \frac{1}{2}x + 89[/tex]

Step-by-step explanation:

slope-intercept form: y  = mx + b

y = (x , y)

x = (x , y)

m = slope = 1/2

b = y-intercept = 89

Plug in the corresponding numbers & variables to the corresponding variables:

y = (1/2)x + 89

[tex]y = \frac{1}{2}x + 89[/tex]  is your answer.

Answer:

C, zero slope should be correct

Step-by-step explanation:

hope this helps, sorry if im wrong

Answer:

zero slope

Step-by-step explanation:

In a zero slope, the numerator is zero. This means that the “Y” points (Y1 and Y2) produce a difference of zero between the variables. Zero divided by any non-zero denominator will result in zero. This also results in a straight, horizontal line on the graph that neither climbs nor descends along the “X” axis.

In right triangle ABC, AC = 4 and BC = 5. A new triangle DEC is formed by connecting the midpoints of AC and BC. What is the area of triangle ABC? *​

Answers

You can use the Pythagoras theorem to find the height of the triangle given and then by the height and the base of the triangle, you can find its area.

The area of the triangle ABC is 6 square units.

Right angled triangle:

A right angled triangle is a triangle having one of its angle with measure of 90 degrees.

The slant side of that triangle is called Hypotenuse and it is the longest side in that triangle.

The Pythagoras theorem:

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

[tex]|AC|^2 = |AB|^2 + |BC|2[/tex]

How to find the area of given right angled triangle ABC?

Refer to the diagram attached below.

Since we have right angle at angle A, and we have

|AC| = 4 units, |BC| = 5 units, let |AB| = [tex]x[/tex] units, then

[tex]|AC|^2 + |AB|^2 = |CB|^2\\4^2 + x^2 =5^2\\x ^2 = 25-16\\x = \sqrt{9} = 3 \text{\:(Positive root since x is length which is non negative quantity)}[/tex]

Area of a triangle is half of its base times height.

Since the line AC s perpendicular to AB, thus we can take base as AB and height as AC, then we have:

[tex]Area = \dfrac{1}{2} \times |AC| \times |AB| = \dfrac{1}{2} \times 4 \times 3 = 6 \: \rm unit^2[/tex]

Thus,

The area of the triangle ABC is 6 square units.

Carter used 1 1/3 gallons of paint to paint 2/5 of a wall. How many gallons will it take to paint the whole wall? Show your reasoning with a diagram.​

Answers

Answer:

3 1/3 gallons

Step-by-step explanation:

It is more helpful to think of the wall as 5 sections. if two sections used 4/3, by logic one section uses 2/3 (because 4/3 ÷ 2 = 2/3). since there are 5 sections, 2/3 × 5 you get 10/3. turn it into a mixed fraction and you get 3 1/3.

if five slices of pizza costs 5.50 how much would two slices cost? ten slices? half a slice?

Answers

Answer:

The first thing we must do for this case is to define variables.

We have then:

x: number of slices

y: total cost

We write the linear function that relates the variables.

We have then:

Then, we evaluate the number of slices to find the total cost.

-two slices cost:

We substitute x = 2 in the given equation:

Answer:

two slices = 2.2 $

-ten slices cost:

We substitute x = 10 in the given equation:

Answer:

ten slices = 11 $

-half a slice cost:

We substitute x = 1/2 in the given equation:

Answer:
