write the equation for the line that goes through the points (-8,2) and (7,7)

Answers

Answer:

y=3x+(0,4.5)

Step-by-step explanation:

i did this in my head, but the difference between -8 and 7 is 15. the difference between 2 and 7 is 5. it's rise over run so (15,5). that simplified is (3,1)/3. that is the slope. now you need a graph to see the y-int. the y-int is around 4.5.

Please helpp anyone

Answers

Step-by-step explanation:

let equation of the line be y = mx + b.

m = - 100/60 = - 5/3

sub (0, 100):

100 = -5/3(0) + b

b = 100

therefore, y = -5/3x + 100

Marie has a container of oatmeal. She uses 1/4 cup of the oatmeal for breakfast and 3/8 cup for a cookie recipe. What is the total change in the amount of milk she has? Why are 1/4 and 3/8 represented with negative numbers on the number line in the example

Answers

Answer:

-5/8

1/4 and 3/8 are represented as negative because it depicts a decline or reduction in the initial amount

Step-by-step explanation:

Given that :

Breakfast = 1/4 cup of Oatmeal

Cookie recipe = 3/8 cups

Change in total amount had :

total amount used = (breakfast + cookie recipe)

= 1/4 + 3/8

= (2 + 3) / 8

= 5 / 8

Hence, change in amount had = - 5/8

1/4 and 3/8 are represented as negative because it depicts a decline or reduction in the initial amount

1) If there are 54 people in a class and the ratio of girls to total people is 2:5, how many
girls and boys are there in the class?

Answers

From the ratio you can deduce 2:5 girls and 3:5 boys. Divide 54 by 5 and you get 10.8. 10.8*2 = 21.6 and 10.8*2= 32.4 which adds to the total 54. There cannot be a fraction of a person, you need to round the decimals. There are 22 girls and 32 boys.

There are 22 girls and 32 boys in the class.

Ratio and proportion :

Given that, there are 54 people in a class

and the ratio of girls to total people is [tex]2:5[/tex]

Number of girls in the class is,

[tex]=\frac{2}{5}*54=21.6[/tex]

In class, there are 22 girls.

Number of boys is, [tex]54-22=32[/tex]

What is an equation of the line that passes through the points (3, -3) and (6,-1)?

Answers

Answer: 2/3x - 5

Step-by-step explanation:

The equation of a line passing through the given points is y = 2x/3-3

What is an equation?

An equation is a mathematical statement that shows that two mathematical expressions are equal.

Given that, a line is passing through the points (3, -3) and (6,-1)

We know that, the equation of a line passing through two points is given by,

y-y₁ = (y₂-y₁/x₂-x₁)(x-x₁)

Therefore,

y+1 = (-1+3)/(6-3)(x-3)

y+1 = 2/3(x-3)

y = 2x/3-2-1

y = 2x/3-3

Hence, The equation of a line passing through the given points is y = 2x/3-3
