I need help with this rate of change problem

Answer:

1,7

Step-by-step explanation:

7x = 9x-2

2 = 2x

x = 1

y = 7

Answer:

(1,7)

Step-by-step explanation:

okay, since the equations are both equal to y we can set the equations to be equal to each other and solve for x

9x - 2 = 7x

subtract 9x from both sides

-2 = -2x

divide both sides by -2

x = 1

now that we have the x-value we can plug it back in to get a y-value

y = 7x

y = 7(1)

y = 7

The birth order is related to the choice of major. The statistics professor at the university polled his students in finding out the majors and position based on family birth order.

Statistics, a branch of applied mathematics, is concerned with the collection of, description of, analysis of, and inferences from quantitative data. Major contributions to the mathematical theories underlying statistics come from probability theory, linear algebra, and differential and integral calculus.

Finding valid inferences about big groups and general events from the behavior and other observable characteristics of small samples is a major challenge for statisticians, or persons who study statistics. These small samples are representative of a small subset of a larger group or a small number of isolated occurrences of a widespread phenomena.

Almost all scientific fields, including the physical and social sciences, as well as business, the humanities, government, and manufacturing, use statistics. Fundamentally, statistics is an area of applied mathematics that resulted from the application of calculus and linear algebra, among other mathematical techniques, to probability theory.

Answer: 32x-8

Step-by-step explanation: 8x times 3 is 24x and 4x times 2 is 8x

                                            24x +8x is 32x

                                           3 times-2 is -6  2 times-1 is -2

                                            -6-2 is -8

                                          so therefore the answer is 32x-8

Rita's new hourly wage will be $18.72.

Step-by-step explanation:

To solve this problem, we first need to calculate 4% of $18.00 to find the raise.

18 x 0.04 = 0.72

Now, we need to add this to the original hourly wage of $18.

18 + 0.72 = $18.72

Therefore, Rita's new hourly wage will be $18.72.

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

6(x - 1) = -72

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that -72 does indeed equal -72.

∴ x = -11 is a solution to the equation.

Answer:

x = - 11

Step-by-step explanation:

Given

6(x - 1) = - 72 ← divide both sides by 6

x - 1 =  - 12 ( add 1 to both sides )

x = - 11

The price of the cheaper vehicle is $34000. And the price of the other vehicle is $ 57000. The total becomes $91000.

The total price for two cars at a dealership is $91,000, where one car's price is $11,000 less than twice the other.

There are numerous ways in which one may define an equation. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an ‘equal’ sign. The most basic and simple algebraic equations consist of one or more variables in math.

Let the price of one car be 'X' and other be 'Y' such that:

X+Y = $91000.

According to the question,

X = 2Y - $11000

Manipulating and calculating both the equations we get,

X = $57000 and Y = $34000.

So the cheaper car is of $34000.

Answer:

Option A: 12

Step-by-step explanation:

From the image of the triangle given, we can see that:

XM = ZM

We are given that:

XM = 2x + 2 and ZM = 4x - 8

Thus;

2x + 2 = 4x - 8

Rearrange to get;

4x - 2x = 8 + 2

2x = 10

x = 10/2

x = 5

Thus, XM = 2(5) + 2

XM = 12

When 120 hours shared in the ratio it gives 50 hours : 70 hours

Lets add up the ratio= 5 + 7 =12

Now for 5/12 of the time =  5/12 × 120

                                        = 50 hours

And for 7/12 of the time  =  7/12 × 120

                                        = 70 hours

A ratio in mathematics describes the amount of times one number is present in another. For instance, the proportion of oranges to lemons in a bowl of fruit is eight to six if there are eight oranges and six lemons (that is, 8:6, which is equivalent to the ratio 4:3). The proportions of oranges to the overall amount of fruit are 8:14 for oranges and 6:8 (or 3:4) for lemons (or 4:7).

The quantities in a ratio can be of any form, including counts of people or things, measures of lengths, weights, or times, etc. Both numbers must be positive in the vast majority of situations.

 - This is another way of saying multiply each side by -1.

 - Since we have 2 negatives next to each other, one must be turned into a positive, in this case it's the x.

 - Combine them because you can only have one variable (x) in the end.

 - We do this to get rid of not only the 10 but the other numbers as well, and the only way to do so it to cancel them out.

 - We do this to get x alone with one number left over, and the only way to do so is to cancel everything out by dividing.
