X=2y-3 slope intercept form

1 answer:

4 0

To get the standard form, you would solve for y.

Let's solve for y.

x=2y−3

Step 1: Flip the equation. (becomes easier)

2y−3=x

Step 2: Add 3 to both sides.

2y−3+3=x+3

2y=x+3

Step 3: Divide both sides by 2.

2y/2=x+3/2

y=1/2x+3/2

Answer:

26.04cm^2

Step-by-step explanation:

28 divided by 20 is 1.4. 1.4 times the area will give you the area of the other figure. 1.4 x 18.6 = 26.04

Consider the quadratic function f(x) = x2 – 5x + 12. Which statements are true about the function and its graph? Select three op

Rashid [163]

Answer:

I will assume the equation is supposed to be f(x) = x^2 – 5x + 12 since it is said to be a quadratic equation.

Step-by-step explanation:

See attached graph.

The value of f(–10) = 82 False

f(-10) = (-10)^2 - 5*(-10) + 12

f(-10) = (100) +50 + 12

f(-10) = 162

The graph of the function is a parabola. True

The graph of the function opens down. False

The graph contains the point (20, –8). False

The graph contains the point (0, 0). False

A gas station customer pumps exactly six gallons

ki77a [65]

Answer:

Please find attached the graph of the relationship between the gallons, g, and cost, C

The relationship between the cost and number of gallons is cost C = $3.25 × Number of gallons, g

Step-by-step explanation:

The given parameters are;

Number of Gallons, g ${}$ Cost, C

6 ${}$ $19.50 ${}$

22 $71.50

From the given coordinates, we generate the graph using Microsoft Excel, as seen in the attached graph

The given coordinates can be used to find the equation of the relationship in point and slope form as follows;

The slope of the the given coordinates are (71.5 - 19.5)/(22 - 6) = 3.25

The equation of the graph in point and slope form is C - 71.5 = 3.25·(g - 22)

C - 71.5 = 3.25·(g - 22)

C = 3.25·g - 3.25 × 22 + 71.5 = 3.25·g - 0

C = 3.25·g

The relationship between the cost and number of gallons is cost C = $3.25 × Number of gallons, g

From the above equation, we have, that the price per gallon is $3.25
