What is an equation for the line that passes through points (2.-3) and (1, 2)? (+ 3) = -5(x - 2) b. (y - 3) = 5(x ! 2) (y - 3) = -5(.x + 2) d. (+3) = S(x - 2)​

Answers

Answer:

A. y + 3 = -5(x - 2)

Step-by-step explanation:

The slope is:

2 - (-3) / 1 - 2 = 5 / -1 = -5.

Then, put it in point slope form (which was [tex](y - y1) = m(x-x1)[/tex] where m is the slope, and (x1, y1) is the coordinate point it gives you. You can use m = -5, x1 = 2 and y1 = -3.)

y + 3 = -5(x - 2)

Find the value of x.

Step-by-step explanation:

Let's solve your system by substitution.

4x+3y=5;2y=x−4

brainliest please?

Answer:

The answer to the system of equations is x = 2 and y = -1

Step-by-step explanation:

We can substitute the variables and see how they work with the equations.

2 (-1) = (2) - 4

-2 = 2 - 4

-2 = -2

4 (2) + 3 (-1) = 5

8 + (-3) = 5

8 - 3 = 5

5 = 5

Marcy is baking blueberry pies to sell at her bakery. She starts with 8 3/4 cartons of blueberries, of which she uses 1/2 for the first batch of pies. How many cartons of blueberries does Marcy use for the first batch of pies?

Answers

Answer: Marcy used [tex]\dfrac{35}8[/tex] cartons of blueberries for the first batch of pies.

Step-by-step explanation:

Given: Quantities of blueberries = [tex]8\dfrac34[/tex] cartons

[tex]=\dfrac{8\times4+3}{4}=\dfrac{35}{4}[/tex] cartons

Blueberries used for first batch = [tex]\dfrac12[/tex] of (Total)

[tex]=\dfrac12\times\dfrac{35}{4}\\\\=\dfrac{35}{8}[/tex]cartons

Hence, Marcy used [tex]\dfrac{35}8[/tex] cartons of blueberries for the first batch of pies.
