Solve for x.
9 - 2x = 4x - 9

Answers

Answer 1

Answer: x = 3

Step-by-step explanation:

9 - 2x = 4x - 9

18 -2x = 4x

18 = 6x

x = 3

Answer 2

Answer:

1/3

Step-by-step explanation:

you add the 2x onto the 4x to get 6x on one side on the other side you add on the nine so now you have 18=6x then you divide by 18 to get 6/18 or simplified 1/3 also 33.3 as a decimal

The function Y=4.75+2.20(X-1) can be used to determine the cost in dollars for a taxi ride in Houston, TX. What is the rate of change of the cost in dollars with respect to the number of miles?

Answers

Answer:

2.20 dollars/mile

Step-by-step explanation:

Given the function:

y = 4.75 + 2.20(x-1)

Before we get the rate of change of the cost, we need to write the expression in the form y = mx+c where;

m is the rate of change of the cost

From the function given:

y = 4.75 + 2.20(x-1)

Open the parenthesis

y = 4.75 + 2.20x -2.20

y = 2.20x + 2.55

On comparing with the standard

m = 2.20

Hence the rate of change of the cost in dollars with respect to the number of miles is 2.20 dollars/mile

The sum of two numbers is 12 times larger than one set and 29 times larger than the other set. What are those numbers and what is their sum?​

Answers

Answer:

Step-by-step explanation:

This is a very impossible question to solve because we are not given any idea what both sets are, or at least either of them is. And thus, even if we write down an inequality equation, I doesn't solve the question, it rather makes one ask more questions.

If the two numbers are, say, a and b, and the first set is x, while the second set is y then we have an inequality in the sense that

a + b = 12x

a + b = 29y

How to proceed with no idea what x or y is, is well, not possible

4. Substitute y into either original equation:

5. Write the solution as an ordered pair:

Answers

Answer:

The solution to the system of equation is: (-2,3)

Step-by-step explanation:

We need to find the solution to the system of equations: x + 3y = 7 and 2x + 4y = 8

I am placing steps for each point given

1. Isolate x in the first equation:

First equation is:

x+3y=7

Isolating x:

x=7-3y

2. Substitute the value for x into the second equation:

Second equation is:

2x+4y=8

Putting value of x: x=7-3y

2(7-3y)+4y=8

3. Solve for y:

2(7-3y)+4y=8

Multiply 2 with terms inside the bracket

14-6y+4y=8

-2y=8-14

-2y=-6

y=-6/-2

y=3

So, we get value of y: y=3

4. Substitute y into either original equation:

Putting value of y: y=3 in equation 1

x+3y=7

x+3(3)=7

x+9=7

x=7-9

x=-2

So, we get value of x: x=-2

5. Write the solution as an ordered pair:

After solving the equation we get:

x = -2 and y = 3

The ordered pair is: (-2,3)

Answer:

-2,3

Step-by-step explanation:

Isolate x in the first equation:

Substitute the value for x into the second equation:

Solve for y
