Consider the linear system of equations y = 2/5x - 1 and 2x -3y + 1 = 0

The solution of the system of equations is?

we have

[tex]y=\frac{2}{5}x-1[/tex] ----> equation A

[tex]2x-3y+1=0[/tex] ----> equation B

Solve by substitution

substitute the equation A in equation B

solve for x

[tex]2x-\frac{6}{5}x+3+1=0[/tex]

[tex]2x-\frac{6}{5}x+4=0[/tex]

Multiply by 5 both sides to remove the fraction

[tex]10x-6x+20=0[/tex]

The solution is the point (-5,-3)

The question involves solving a system of linear equations from high school algebra. Substituting Y from the first equation into the second and solving for x, we find that x = -5 and Y = -3.

The student is asking about solving a system of linear equations, which is a concept in algebra that falls under high school mathematics. To find the solution to the given linear system, we can use either substitution or elimination methods. Let's use substitution since the first equation has Y isolated.

From the first equation Y = 2/5x - 1, we substitute for Y in the second equation, which gives us 2x - 3(2/5x - 1) + 1 = 0. Simplifying, we get 2x - 6/5x + 3 + 1 = 0, which further simplifies to 4/5x + 4 = 0. Solving for x gives x = -5. Substituting x back into the first equation to find Y yields Y = 2/5(-5) - 1, so Y = -3. Therefore, the solution to the system of equations is x = -5 and Y = -3, which is the point where the two lines intersect.

So, the equation y = 3x + 4 could have not produced the all values in the table as the the ordered pairs in table do not satisfy(equate) the equation.

Checking B) y = -2x + 18

Putting (3, 12), (6, 18) and (9, 24) in y = -2x + 18

So, y = -2x + 18 could have not produced all the values in the table, as (6, 18) does not equate the equation.

Checking C) y = 2x + 6

Putting (3, 12), (6, 18) and (9, 24) in y = 2x + 6

So, y = 2x + 6 could have produced the values of in the table as all the orders pairs in the table satisfy/equate the equation.

Checking D) y = x + 9

Putting (3, 12), (6, 18) and (9, 24) in y = x + 9

So, y = x + 9 could have also not produced all the values in the table, as (6, 18) and (9, 24) do not satisfy/equate the equation.

Answer:

2x + 17

Step-by-step explanation:

Answer:

2(x-17).

Step-by-step explanation:

The given phrase is "two times the difference of a number and 17."

We need to find the expression for given phrase.

Let x be the unknown variable.

Difference is denoted by "-" symbol.

Time is denoted by "×" symbol.

Difference of a number and 17 = x-17

Two times the difference of a number and 17 = 2×(x-17) = 2(x-17)

Therefore, the required expression is 2(x-17).

The equation solved for s is s = 4p - 48h

Solution:

Given that equation a company uses to  calculate pay checks is p = 12h +0.25s

Therefore the given equation is:

p = 12h + 0.25s

Where "h" is the number of hours worked

"s" is the total sales

To find: equation for "s"

Let us solve the given equation for "s"

p = 12h + 0.25s

Now move 12h from R.H.S to L.H.S

p - 12h = 0.25s

Now move from 0.25 from R.H.S to L.H.S

[tex]s = \frac{p-12h}{0.25}\\\\s = \frac{p}{0.25} -\frac{12h}{0.25}[/tex]

We know that, [tex]0.25 = \frac{1}{4}[/tex]

[tex]s = \frac{p}{\frac{1}{4}} -\frac{12h}{\frac{1}{4}}\\\\s = p \times \frac{4}{1} - 12h \times \frac{4}{1}\\\\s = 4p - 48h[/tex]

Thus the equation for s is s = 4p - 48h

0.024 /yr

Step-by-step explanation:

Without interest, the monthly repayment would be;

5 yrs = 12 months * 5 = 60 months

$4200 / 60

= $70

James, however,  pays $78.40 monthly. The interest therefore is;

Jmaes pays a total of $78 * 60 = $4704 at the end of the 5 years. The formula for finding simple interest is;

A = P(1 + rt)

Where:

   A = Total Accrued Amount (principal + interest)

   P = Principal Amount

   I = Interest Amount

   r = Rate of Interest per year in decimal; r = R/100

   R = Rate of Interest per year as a percent; R = r * 100

   t = Time Period involved in months or years

4704 = 4200 (1 + 5r )

4704 = 4200 + 21000r

504 = 21000r

r = 504/21000

r = 0.024

Answer:

The answer is 10/27

Step-by-step explanation:

5/6 times 4/9 is equal to 10/27

Answer: x = -8 ; y = -6

Step-by-step explanation:

1*x-2*y=4

1*x = 4 + 2*y

x = 4 + 2*y

Now you replace the value of x on the following equation:

-1*x+10*y=8

-1*(4 + 2*y) = 8

-4 - 2*y = 8

-2*y = 8+4

-2*y = 12

y = -12/2

y = -6

You replace the value of y in the previous equation:

x = 4 + 2*y

x = 4 + 2*(-6)

x = 4 - 12

x = -8

so we are basically taking the total hrs and subtracting the combined hrs she has worked

h = 20 - (5.5 + 5.25) <== ur equation

The sentence that could be used to find h, the number of hours remaining for Kendra to work this week is h = 20 - (5.5 + 5.25).

An expression is a sentence with a minimum of two numbers or variables and at least one math operation.

Kendra works 20 hours each week. So far this week, she has worked 5.5 hours on Tuesday and 5.25 hours on Thursday.

Let h be the number of hours remaining for Kendra to work this week.

The sentence that could be used to find h, the number of hours remaining for Kendra to work this week is;

A number of hours remaining for Kendra to work this week = Total number of hours - working on Tuesday - working on Thursday.

h = 20 - 5.5 - 5.25

h = 20 - (5.5 + 5.25)

Hence, the sentence that could be used to find h, the number of hours remaining for Kendra to work this week is h = 20 - (5.5 + 5.25).

Answer:

Step-by-step explanation:

I'm pretty sure the sum of all angles has to be 360°

and 70+70+40+40=220

so 220+x=360

we figure this out by taking 360-220 which equals 140

and then we divide 140 by 2 which is 70.

To double check, if you add 70+70+40+40+70+70, it equals 360.

The value of x from the given parallelogram is 70°. Therefore, option B is the correct answer.

A parallelogram is a special kind of quadrilateral that is formed by parallel lines. The angle between the adjacent sides of a parallelogram may vary but the opposite sides need to be parallel for it to be a parallelogram. A quadrilateral will be a parallelogram if its opposite sides are parallel and congruent.

Given that, ABCD is a parallelogram.

Here, ∠A+∠B+∠C+∠D=360°

70°+x+40°+70°+x+40°=360°

Answer:

Step-by-step explanation:

x-3=5

add the 3 to both sides of the equal sign

x-(3+3)=(5+3)

x=8

Answer: X = 8

Step-by-step explanation: To solve for x in this equation, we want to get x by itself on the left side of the equation. Since 3 is being subtracted from x, to get x by itself, we need to add 3 to the left side of the equation. If we add 3 to the left side, we must also add 3 to the right side.

Notice that on the left side -3 and +3 cancel each other out so we're simply left with x. On the right side, 5 + 3 gives us 8 so we have x = 8.

We can check our answer by substituting 8 back into the original equation. So we have (8) - 3 = 5 or 5 = 5 which is a true statement so our answer is correct.

As the inequality is given as:

                                12x + 9x - 3 ≤ 3(2x + 14)

and we have to find the value of x.

So,

12x + 9x - 3 ≤ 3(2x + 14)

Step 1: Simplify both sides of the inequality

21x - 3 ≤ 6x + 42

Step 2: Subtract 6x from both sides.

21x - 3 - 6x ≤ 6x + 42 - 6x

15x - 3 ≤ 42

Step 3: Add 3 to both sides.

15x - 3 + 3 ≤ 42 + 3

15x  ≤ 45

Step 4: Divide both sides by 5

15x/5 ≤ 45/5

3x  ≤ 9

x ≤ 9/3

Answer:

Youngest Age = 6

Middle Age = 9

Oldest Age = 12

Step-by-step explanation:

Let youngest age be x

Middle one age be y

Oldest age be z

So,

x < y < z

Now lets come up with the equations using the statements.

Three age combined is 27, so we can write:

x + y + z = 27

Oldest is TWICE youngest, so we can write:

z = 2x

Middle is 3 YEARS OLDER than youngest, so we can write:

y = x + 3

Now we replace first equation with 2nd and 3rd, to get:

x + y + z = 27

x + x + 3 + 2x = 27

We can solve this for x:

x + x + 3 + 2x = 27

4x + 3 = 27

4x = 24

x = 24/4

x = 6

Now finding y:

y = x + 3

y = 6 + 3

y = 9

Now finding z:

z = 2x

z = 2(6)

z = 12

Thus,

Youngest Age = 6

Middle Age = 9

Oldest Age = 12
