Which equation best represents the relationship between x and y in the graph?

Answers

Answer:

Y=1/2x+2

Step-by-step explanation:

The 2 is crossing the y-axis not the x so it crosses out the first two equations and the third one wouldn't work because -4 is through the x-axis meaning it can't be b.

graph a line that contains the point (3,-6) and has slope of -1/2

Answers

Answer:

Step-by-step explanation:

Let the equation of the line is,

y = mx + b

Here, m = slope of the line

b = y intercept

Since, m = -[tex]\frac{1}{2}[/tex]

Equation of the line will be,

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

Since, a point (3, -6) lies on the line,

-6 = [tex]-\frac{3}{2}+b[/tex]

b = -6 + 1.5

b = -4.5

Equation of the line will be,

[tex]y=-\frac{x}{2}-\frac{9}{2}[/tex]

Table for the points on the graph,

x -4 -3 -2 -1 0

y -2.5 -3 -3.5 -4 -4.5

Plot these points and join them to get the graph of a line.

The point where the graphs of two equations intersect has y-coordinate 2. One equation is y=−3x+5 . Complete the other equation in the form y=mx+b if its graph has a slope of 1.

Answers

Answer:

y = x + 1

Step-by-step explanation:

y = -3x + 5

Let y = 2

2 = -3x +5

-3 = -3x

x = 1

(1, 2)

y = mx + b

y = 1x + b

2 = 1 + b

b = 1

Therefor, the other one is, y = x + 1

A service center charges a fee of x dollars for an oil change plus y dollars per quart of oil used. A sample of its sales record is shown.

A table shows the oil tank size in quarts and total cost for two customers. Customer A: Oil tank size, 5 quarts. Total cost, 22.45 dollars. Customer B: Oil tank size, 7 quarts. Total cost, 25.45 dollars.

Write a system of linear equations that represents this situation.

Equation for customer A:
____=22.45$

Equation for customer B:
___=25.45$

Question 2
Find the fee and cost per quart of oil.

$ fee?

$ per quart of oil?

Answers

Answer:

Fee - $14.95, and $1.5 per quart of oil

Step-by-step explanation:

Equation for customer A:

x + 5y =22.45$

Equation for customer B:

x + 7y=25.45$

Subtract the first equation from the second and solve for y:

x + 7y - x - 5y = 25.45 - 22.452y = 3y = 3/2y = 1.5

Find x by substituting the value of y:

x + 5*1.5 = 22.45x = 22.45 - 7.5x = 14.95

The theoretical probability of spinning a 1 is

Answers

Answer:

Step-by-step explanation:

That depends on how many sections there are. If there are 2 sections, then it will be a 50/50 chance it lands on 1 if there are 3 sections then it would be 1/3 or for 4, 1/4, and for 5, 1/5, etc.

The theoretical probability of spinning a 1 is 1/4.

What is Probability?

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

Theoretical probability is the probability that we find through the theoretical approach without doing the experiment.

Total number of sections that the spinner has = 4

Number of sections numbered 1 = 1

Probability of spinning a 1 = 1/4

Hence the required probability = 1/4.

Answer:

p = 1

Step-by-step explanation:

[tex]p-1 = 5p + 3p - 8[/tex]

combine like terms on the right side

[tex]p - 1 = 8p - 8[/tex]

subtract 8p from both sides

[tex]-7p - 1 = -8[/tex]

add 1 to both sides

the length and width of the garden.

Answers

Answer:

Length: 48

Width: 12

Step-by-step explanation:

Substition

l - 2w = 24

I = 60 - w

60 - w - 2w = 24

60 - 3w = 24

-3w = -36

w = 12

Substitute it into the equation to get the length.

l = 60 - 12

l = 48
