Answer 1
step 1.) Multiply both sides of the equation by -6

step 2.) Sum the equations vertically to eliminate at least one variable

step 3.) Divide both sides of the equation by

step 4.) Substitute the given value of into the equation x - 2y = 10

step 5.) Solve the equation for x

step 6.) The possible solution of the system is the ordered pair (x , y)

step 7.) Check if the given ordered pair is the solution of the system of equations

step 8.) Simplify the equalities

step 9.) Since all of the equalities are true, the ordered pair is the solution of the system


So your answer would end up being (40/13 , -45/13) !! Hope that helps you out :D !!
Answer 2

Answer:

x=4 y=-3

Step-by-step explanation:

I will solve your system by substitution.

(You can also solve this system by elimination.)

x−2y=10 ; 6x+3y=15

Step: Solve x −2y= 10for x:

x − 2y + 2y = 10 + 2y (Add 2y to both sides)

x=2y+10

Step: Substitute 2y+10 forx in 6x+3y=15:

6x+3y=15

6x+3y=156(2y+10)+3y=15

15y+60=15 (Simplify both sides of the equation)

15y+60+−60=15+−60 (Add -60 to both sides)

15y=−45

15y/15=−45/15(Divide both sides by 15)

y=−3

Step: Substitute −3 for y inx=2y+10:

x=2y+10

x=(2)(−3)+10

x=4(Simplify both sides of the equation)

Answer:

x=4 and y=−3

I NEED HELP ASAP!!!!

Answers

Answer:

  (a)  1

  (b)  1 3/4

  (c)  [-2, 4]

  (d)  [-1/4, 2]

Step-by-step explanation:

Apparently, the vertex of the graph is (1, 2) and it goes through points (-1, 1) and (3, 1). In vertex form, the equation for this is ...

  y = a(x -1)^2 +2

We can find the value of 'a' from the point (3, 1):

  1 = a(3 -1)^2 +2 = 4a +2 . . . . substitute for x and y, and simplify

  -1 = 4a . . . . . . . subtract 2

  -1/4 = a . . . . . . divide by 4

So, ...

  f(x) = -1/4(x -1)^2 +2

__

(a)

Above, we assumed point (-1, 1) was on the graph:

  f(-1) = 1

__

(b)

Using the equation we found, ...

  f(2) = -1/4(2 -1)^2 +2 = -1/4 +2

  f(2) = 1 3/4

__

(c)

The domain is the horizontal extent of the graph, apparently from x = -2 to x = 4.

  domain: [-2, 4] or -2 ≤ x ≤ 4

__

(d)

The range is the vertical extent of the graph. The minimum can be found at the end of the domain:

  f(4) = -1/4(4 -1)^2 +2 = -9/4 +2 = -1/4

The maximum has already been established as the vertex at y=2.

  range: [-1/4, 2] or -1/4 ≤ y ≤ 2

What is the sum of the measures of the interior angles of a 20-sided figure?.

Answers

Answer:

3240°

Step-by-step explanation:

The equation to find the sum of the measures of the interior angles of a figure is:

(n-2)*180

Where n represents the amount of sides the figure has. In this case the figure has 20 sides so its interior angles sum up to:

(20-2)*180=18*180=3240°

The graph below models how one county fines drivers that get a ticket for speeding based on how many miles over the speed limit. Based on the graph, what would the fine be for a person that was ticketed for driving 62 mph in a zone that had a maximum speed of 55 mph?

$150

$100

$50

$200​

Answers

Answer:

$100

Step-by-step explanation:

The bottom row is how many mph the driver is over, the left row is how much it costs per mph over. Since 62mph in a 55mph zone is 7mph over, you go the 7 on the bottom, and go up until you get to the point, then see what the number on the left is. In this case, it would be 100. So therefore the fine is $100.

Using the graph of f(x) and g(x), where g(x) = f(k⋅x), determine the value of k.

Answers

Answer:

1/3

Step-by-step explanation:

This is about the interpretation of the graph

From the graph, we can see the 2 lines representing function f(x) and function g(x).

Now for us to find the value of x in g(x) = k⋅f(x), we need to get a mutual x-coordinate where we can easily read their respective y-coordinate values.

We see that the best point for that is where x = -3.

For f(x), when x = -3, y = 1

For g(x), when x = -3, y = -3

we can rewrite them as;

x = -3, f(-3) = 1 and x = -3, g(-3) = -3

Let us plug in the relevant values into g(x) = k⋅f(x) to get;

-3 = k(1)

Thus; k = -1/3

Linear equation

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change (slope) and b is the y intercept.

Given that the relationship between f(x) and x is given by:

f(x) = 3x - 2

When x = 0: f(0) = 3(0) - 2 = -2

When x = 1: f(1) = 3(1) - 2 = 1
