what's the difference between two step equations and one step equations

Answer:

4x+6y<=10

Step-by-step explanation:

The linear inequality that describes the graph is 4x+ 6y ≤ 10.

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

As, The bold straight line passes through the points (1,1) and (-2, 3).

so, equation of line will be

(y- 1) = (3-1)/ (-2-1) (x-1)

y-1 = 2 / (-3) (x-1)

-3y + 3 = 2x - 2

-3y -2x = -5

If we multiply by 2 both side we get

-6y - 4x = -10

4x+ 6y= 10

So, the required inequality for gray area is 4x+ 6y ≤ 10.

Answer:

C. The total cost increases by $2.50

Step-by-step explanation:

This is because 1 dollar is constent--- you will always have 1 dollar.

However 2.5 is the change, you have to times a number to get the answer.

EX:

(t) = 2.5t + 1

(4) = 2.5( 4) + 1 ----- plug in 4 for t

= 10 +1

= 11

The is the multiplyer or change is the 2.5t

and when you graph it it will almost always be the slope of the line.

A=bh/2 is the formula for the area of a triangle.

A=bh is the formula for the area of a rectangle or a parallelogram.

If the 6 & 4 area the base & height of a rectangle, then (6)(4) = 24 in^2

If the 6 & 10 are the base and height of a triangle, then 1/2(6)(10) = 30 in^2

Answer:

6710.46x

Step-by-step explanation:

The solution is : the value of x is x = 9.75.

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

You need to convert from mixed number to decimal number. To do this you can follow the steps shown below:

Step 1: You must divide the numerator of the fraction by the denominator of the fraction.

Step 2: Now you must add the quotient obtained to the Whole number part.

So, you get:

3 + 1/4

=3 + 0.25

= 3.25

Then, the scale image that maps "Figure a" onto "Figure b" is:

1: 3.25

Finally, in order to find the value of "x", you need to multiply the given length of the corresponding side of "Figure a" by .

Therefore, you get that the result is:

x = 3 * 3.25

or, x = 9.75

Hence, The solution is : the value of x is x = 9.75.

Answer: x = 1 and y = -1

Step-by-step explanation:

Since both equations are equal to y, that means the equations are both equal to each other

5x - 6 = -4x + 3

Solve for x how you would traditionally do it with any other one-variable equation

9x = 9

x = 1

Plug the now known x value into either equation and you will get your y value.

5(1) - 6 = -1

-4(1) + 3 = -1

Martha can write 3.75 essays in 15 hours. (Which is a lot for me)

Step-by-step explanation:

First, I divide 2 by 8.

2 ÷ 8 = 0.25

Next I multiply 0.25 by 15.

0.25 * 15 = 3.75

So, the answer is 3.75

Hope this helps! :)

Step-by-step explanation:

in 8 hours she wrote = 2 essay

Answer:

(4,8)

Step-by-step explanation:

y = 2x

y = 7x-20

Step 1: plug in 2x for y

Step 2: subtract 7x on both sides

Step 3: divide by -5 on both sides

Step 4: plug in 4 into y = 2x

2x = 7x -20

-7x      -7x

-5x  = -20

-5         -5

x = 4

Answer:

Step-by-step explanation:

Let x equal number of weeks and y equal money in the bank.

Nancy, y=425+25x

Sam, y=705-15x

The system of equations:

Nancy:   [tex]y=\$425+\$25x[/tex]

Sam :   [tex]y=\$705-\$15x[/tex]

Given:

Amount in Nancy's bank = $425

Amount saved by Nancy each week = $25

Amount in Sam's bank = $705

Amount spend by Sam each week = $15

To find:

The system of equations describing the given models.

Solution

1) Amount in Nancy's bank = $425

Amount saved by Nancy each week = $25

Let the number of weeks Nancy saving her money be 'x'.

Let the total amount of money in Nancy's bank after x weeks be 'y'.

[tex]y=\$425+\$25\times x\\y=\$425+\$25x[/tex]

The equation for Nancy:

[tex]y=\$425+\$25x[/tex]

2)

Amount in Sam's bank = $705

Amount spend by Sam each week = $15

Let the number of weeks Sam spending his money be 'x'

Let the total amount of money left in Sam's bank after x weeks ='y'

[tex]y=\$705-\$15\times x\\y=\$705-\$15x[/tex]

The equation for Sam:

[tex]y=\$705-\$15x[/tex]

Answer:

(-1, -5)

Step-by-step explanation:

[tex]\left \{ {{y=5x} \atop {y=9x+4}} \right.[/tex]

1. We must calculate x, for that we must substitute y, so we have:

5x=9x+4

2. Now we solve the equation.

5x-9x=4

-4x=4

x=-1

3. Now we must calculate y

y=5x

y=5(-1)

y=-5

And the answer is (-1, -5)

Answer:

9, among other ways denotes the repeating decimal consisting of infinitely many 9s after the decimal point (and one 0 before it). This repeating decimal represents the smallest number no less than every decimal number in the sequence (0.9, 0.99, 0.999, ...). This number is equal to 1.

Step-by-step explanation:

The function f(x) will be sometimes positive and sometimes negative on the interval

Option (3) is correct.

An arrangement known as a function connects inputs to essentially one output.

In other words, a function is a relationship between variables, and the nature of that relationship—for example, y = sinx and y = x +6—defines the function.

Given function:

f(x) = (x - 5) (2x - 7) (7x - 3)

The term (x - 5) will be negative if x < 5.

The term (2x - 7) will be negative if x<3.5

So, If x = 4, (x - 5) will be negative but (2x - 7) will be positive, resulting in a negative overall value.

Therefore, if x = 3, then (x - 5) will be negative, as well as (2x - 7), making the whole value negative.

Hence, the function f is sometimes positive and sometimes negative on the interval.
