Find the midpoint of AC is at -2 and C is at 3 on a number line

Answers

2c3 Because when you look at it when you look at the question if I do that and then you were at the AC is at the two and see is that the three on the number line then you would add that on and you’ll get your answer

The value of midpoint of AC will be 0.5.

What is Number line?

Number line is a horizontal line where numbers are marked at equal intervals one after another form smaller to greater.

Given that;

Point A is at - 2 and C is at 3 on the number line.

Now,

Since, Point A is at - 2 and C is at 3 on the number line.

Hence, The midpoint of AC = (- 2 + 3 ) / 2

= 1/2

= 0.5

Thus, The midpoint of AC = 0.5

Estimate amount of cereal in one bag is 5.867 ounces.

What are mathematical operations?

Calculate the answer using a math operator is referred to as a mathematical operation.

Basic mathematical operations are addition, multiplication, subtraction and division.

Total quantity of cereal that Lazare has = 52.8 ounces.

And number of bags into which cereal equally divides = 9

To find the amount of cereal in each bag,

Use mathematical operations,

Since, total bags are 9 and amount of cereal is 52.8 ounces.

So, in one bag amount of cereal = 52.8 / 9 = 5.8666 = 5.867

In one bag there will be 5.867 ounces of cereal.

Which equation represents a line that passes through (0,–8) and (–5,–23)?

A) y = 4x – 8

B) y = –8x + 3

C) y = 5x – 8

D) y = 3x – 8

Answers

The equation of line that passes through points (0,-8) and (-5,-23) is y=3x-8 which is option d.

Given that the line passes through (0,-8) and (-5,-23).

We are required to find the equation of the line that passes through (0,-8) and (-5,-23).

Equation is like a relationship between two or more variables expressed in equal to form. Equation of two variables look like ax+by=c. It may be linear equation, quadratic equation, cubic equation, and many more depending on the power of the variable.

The formula to form the equation from two points is as under:

[tex](y-y_{1}) =(y_{2} -y_{1} )/(x_{2} -x_{1} ) * (x-x_{1} )[/tex] in which [tex](x_{1} ,y_{1} ),(x_{2} ,y_{2} )[/tex] are the points.

(y+8)=(-23+8/-5-0)(x-0)

y+8=(-15/-5) x

y+8=3x

y=3x-8

Hence the equation of line that passes through points (0,-8) and (-5,-23) is y=3x-8 which is option d.

write the slope intercept form of the equation of each line

Answers

Answer:

Y= - 1/5x-4

Step-by-step explanation:

slope intercept form: y=mx+b

Slope formula: rise/run

(5,-5) AND (0,-4)

-5+-4= -1

5+0= 5 AKA - [tex]\frac{1}{5}[/tex] or -1/5

The m in y=mx+b is the slope, the equation above is the sloe formula meaning -1/5 is the slope. The b is the y, when it is at 0. The y at 0 for this equation is -4. Thus, when plugging in the equation, y=-1/5x-4
