Answers

Answer 1

(-2,-4)

x=-2, y= -4

Have a good day

Answer 2

Answer:

(-2,-4)

Step-by-step explanation:

3x-2y=2

5x-5y=10

--

Multiply 3x-2y=2 by -5 to turn it into -15x+10y=-10

Mutiplu 5x-5y=10 by 2 to turn it into 10x-10y=20

--

Eliminate y

-15x+10y=-10

10x-10y=20

= -5x=10

Divide by -5

x=-2

--

Plug -2 to the first equation

3(-2)-2y=2

-6-2y=2

Move -6 to the other side by adding 6 to both sides

-2y=8

Divide by -2

y=-4

(x,y) = (-2,-4)

Find an equation for the perpendicular bisector of the line segment who’s endpoints points are (-9,3) and (1,7).

Answers

Answer:

y = 2/5x + 33/5

Step-by-step explanation:

(-9,3) and (1,7)

m=(y2-y1)/(x2-x1)

m=(7-3)/(1+9)

m=4/10

m = 2/5

y - y1 = m(x - x1)

y - 3 = 2/5(x + 9)

y - 3 = 2/5x + 18/5

y = 2/5x + 33/5

(i) Draw a line segment AB = 7 cm.

(ii) With A as centre and radius more than half of AB, draw arcs, one on each side of AB.

(iii) With B as centre and same radius as before, draw arcs, cutting the previously drawn arcs at X and Y respectively.

(iv) Now join XY, meeting AB at O.

Joe measures side lengths of triangular canvas to be 22 inches, 10 inches and 11 inches. Could those be correct measurements?

Answers

Answer:

Incorrect measurement

Step-by-step explanation:

Given

Shape: Triangle

Length: 22in, 10in and 11in

Required: Determine if the measurements are correct

For the measurement of a triangle to be true, the sum of any 2 sides must be greater than the length of the third side.

i.e.

[tex]22 + 10 > 11[/tex] --- True

[tex]22 + 11 > 10[/tex] --- True

[tex]11 + 10 > 22[/tex] --- False

Since all three conditions are not true, then the measurements are incorrect

:Find x+y, if: 2x+3y=8 and 3x+5y=13

Answers

Answer:

x=1

y=3

Step-by-step explanation:

Heres a photo with explanation

The solution of the equations 2x + 3y = 8 and 3x + 5y = 13 will be (1, 2). Then the value of the expression x + y will be 3.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The equations are given below.

2x + 3y = 8             ...1

3x + 5y = 13            ...2

Multiply equation 1 by 3 and equation 2 by -2, then we have

6x + 9y = 24

-6x - 10y = - 26

Add the above equations, then we have

- 26 + 24 = 9y - 10y

y = 2

Then the value of the variable 'x' is calculated as,

3x + 5(2) = 13

3x + 10 = 13

3x = 3

x = 1

Then the value of the expression x + y is calculated as,

⇒ x + y

⇒ 1 + 2

⇒ 3

The solution of the equations 2x + 3y = 8 and 3x + 5y = 13 will be (1, 2). Then the value of the expression x + y will be 3.

Answer:

131°

Step-by-step explanation:

to find the total degrees of this polygon, we use the equation

=> n - 2 × 180°                         (n= number of sides)

5 - 2 × 180° = 540°

now by using angle sum property,

540° = 80° + 148° + 81° + 100° + [tex]x[/tex]°

540° = 409° + [tex]x[/tex]°

[tex]x[/tex]° = 540° - 409°

[tex]x[/tex]° = 131°

How many solutions does this problem have
Y=-2x -4
Y= 3x plus 3

Answers

Answer:

There is one possible solution

Step-by-step explanation:

Here, we want to get the number of solutions

We can proceed to solve the equation

we have two y values so we can directly equate the x parts

-2x - 4 = 3x + 3

3x + 2x = -3-4

5x = -7

x = -7/5

To get y, we substitute

We can only get one value of y too

So we have a point (x,y) as the solution to the system of equations

Answer:

Step-by-step explanation:

Substitute y = 2x + 22 in equation (I)

3x = 2x + 22           {Subtract 2x form both sides}

3x -2x = 22              

      x = 22

Answer:

Step-by-step explanation:

3x = y

y = 2x + 22

How to write algebraic expression?

Algebraic expression are the expression which consist the variables, coefficients of variables and constants.

The algebraic expression are used to represent the general problem in the mathematical way to solve them.

Steps to write down the simple algebraic expression-

Identify all the factors of the expression.Assume a variable for the changing values.Put a coefficient for the variable, if there is any rate of change of variable.Use constant numbers for the fixed values.

a. Give 2 input-output pairs that represent this function.

There is total 25 cent is 1 quarter. Thus, when if there are 2 quarters, then the value of cent is 50 and when there are 4 quarters, then the value of cents is 100 cents.

Hence, the two pairs should be as,

(2, 50), (4, 100)

b. Write an equation that represents this function.

As, v is the value of quarters in cents. There is total 25 cent is 1 quarter. The total quarter is n. Thus, the function can be given as,

[tex]v(n)=25\times n\rm \;\;cents[/tex]

c. Find the output when the input is 10.

Put the value 10 on the place of n in the above equation as,

[tex]v(10)=25\times (10)\\v(10)=250\rm cents[/tex]

The output when the input is 10 is 250 cents.

d. Identify the independent and dependent variables.

The independent value is the number of quarters and the dependent variable is the value of cents.

Hence, the independent value is the number of quarters and the dependent variable is the value of cents and the  equation that represents this function is,

[tex]v(n)=25\times n\rm \;\;cents[/tex]
