3x + y = -3
y = x + 5
Substitution pls show solving

Answers

Answer 1
3x + y = -3
Substitute y = x + 5 in the ‘y’ spot in the 3x + 7 = -3 equation

3x + y = -3
3x + x + 5 = -3
combine liked terms
4x + 5 = -3
-5 on both sides
4x = -8
/4 on both sides
x = -2

Answer:
x = -2
Answer 2

Answer:

( -2, 3 )

Step-by-step explanation:

3x + y = -3

y = x + 5

Since "y" has been given to us, all we need to do is substitute.

3x + x + 5 = -3

Combine like terms

4x + 5 = -3

Subtract 5 onto both sides

4x + 5 - 5 = -3 - 5

4x = -8

Divide by 4 into both sides to isolate the variable

4x/4 = -8/4

x = -2

Now that we have x ( -2 ), we can substitute that to get what y is.

y = x + 5

y = -2 + 5

y = 3

( x, y ) ---> ( -2, 3 )

Hope this helped!

Sharon is 5 times as old as her daughter. 4 years ago, the square of the sum of their ages is equal to 256. Forming an algebraic equation, find their present ages. ​

Answers

Answer:

Sharon is 36

Her daughter is 7 years and 2 months

Step-by-step explanation:

sharon is 5× as old

her daughter is written as 1 (because we dont know about her age)

then square root of 256 to find square which is equal as said in the queston:which is 16

algebraic equation would be:5n+16 (n represents the years and 5 is how many times older sharon is and 16 is how old their square sum of agewas 4 years ago)

Their present age would be:

Sharon=5x4+16=36

Daughter =36÷5=7 years 2 months

The present age of Sharon is 20 and the Present age of her daughter is 4.

What are algebraic equations?

A mathematical statement in which two expressions are rendered equal to one another is known as an algebraic equation. A variable, coefficients, and constants make up an algebraic equation in most cases.

Given, Sharon is five times her daughter's age. The square of their ages was equal to 256 four years ago. Let the age of Sharon is x and the age of her daughter be y.

Thus the algebraic equation formed as per the given data is,

x = 5*y (Present age)

(x-4 + y -4)^2 = 256 (Four years ago)

Taking square root both the sides

x + y = 24

comparing both equations

5 y + y = 24

y = 4

and x = 20

Therefore, Sharon is currently twenty years old, and her daughter is currently four years old.

We need to multiply 4 to input x and add 5 to the product to get the output 4x+5.

Given that, input of the function is x and the output of the function is 4x+5.

What is the function?

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

To get the out of the function 4x+5, we need to multiply 4 to x and add 5 to the product.

That is represented the figure given below.

Therefore, we need to multiply 4 to input x and add 5 to the product to get the output 4x+5.

Paul has a sum of $260 in $5 and $10 bills. If he has 40 bills in total, how many were of each denomination?

Answers

Answer:

28 5 dollar bills

12 10 dollar bills

Step-by-step explanation:

You can write two equations to model this situation'

x will be the number of 5 dollar bills

y will be the number of 10 dollar bills

x+y=40

5x+10y=260

There are a couple of ways you can solve this but but I will be doing it through substitution because that looks easier (I can explain other methods if you're interested)

So we have x+y=40

If I subtract y from both sides and divide by -1 we get

-x+40=y

We can then plug this value in for y in the second equation

5x+10(-x+40)=260

Distribute the 10 and combine like terms to get

-5x+400=260

subtract 400 from both sides and divide by -5 to get

x=28

This means that there are 28 5 dollar bills. We can plug this value back in for x into our first equation to solve for y

28+y=40

Subtract 28 from both sides

y=12

This means that there were a total of 28 5 dollar bills and 12 10s

Step-by-step explanation:

Given

The attached table

Required

Fill in the gaps

(a) The equation

First, we calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

From the table, we can say that:

[tex](x_1,y_1) = (0,-300)[/tex]

[tex](x_2,y_2) = (300,0)[/tex]

So, we have:

[tex]m = \frac{0 -(-300)}{300 - 0}[/tex]

[tex]m = \frac{0 +300}{300}[/tex]

[tex]m = \frac{300}{300}[/tex]

[tex]m = 1[/tex]

The equation is then calculated using:

[tex]y - y_1 = m(x - x_1)[/tex]

This gives:

[tex]y - (-300) = 1(x - 0)[/tex]

[tex]y +300 = 1(x)[/tex]

[tex]y +300 = x[/tex]

[tex]y= x - 300[/tex]

(b) When x = 54

Substitute 54 for x in [tex]y= x - 300[/tex]

[tex]y = 54 - 300[/tex]

[tex]y = -246[/tex]

Hello!

[tex]slope = 2\\\\y-intercept = (0, 3)\\\\Equation: y = 2x + 3[/tex]

We can find the slope using the slope formula:

[tex]slope = \frac{y_{2} - y_{1}}{x_{2}-x_{1}}[/tex]

Plug in any two points from the table. We can use (0, 3) and (1, 5):

[tex]slope = \frac{5 - 3}{1-0}[/tex]

[tex]slope = 2[/tex]

Now, we can find the y-intercept by finding the y-value at which x = 0.

According to the table, when x = 0, y = 3. Thus, the y-intercept is:

[tex](0, 3)[/tex]

We can write an equation using the slope and y-intercept in the format

y = mx + b where "m" is the slope and "b" is the y-intercept.

Plug in the solved values into the equation:

y = 2x + 3.
