y=3x-1

y=2x+2

Answers

Answer 1
The answer is x=3 and y=8, here’s the work—


Y=3x-1
Y=2x+2
2x+2=3x-1
2=x-1
X=3

3(3)-1=y
9-1=y
8=y
Answer 2

Answer:

x=3

y=8

Step-by-step explanation:

the given equations are y=3x-1 --------(1)

and y=2x+2---------(2)

Using substitution method,

and solving y=3x-1

y+1=3x

or y+1/3 =x ------(3)

Putting the value of x= y + 1 / 3 in equation 2

y= 2x+2

or, y = 2 ( y + 1/3) +2

or, y= 2y + 2 / 3 +2

or, y = 2y + 2 + 6 // 3 ( Taking LCM)

Or, 3 y = 2y + 2 + 6 ( the denominator gets multiplied to y)

OR, 3 Y - 2Y =6 PLUS 2

or y = 8

therefore, y=8

now substituting the value of y=8 in equation (3)

y + 1 /3 = x

or ,,, 8 plus 1 by 3 =x

or,,,,, 9 by 3 =x

Therefore, x is 3

You are creating a logo for a local company in the shape of an isosceles triangle. The legs measure 5 inches each. What is the greatest number of whole inches the base can measure?

Answers

Answer:

9 inches

Step-by-step explanation:

Here, we want to know the greatest length of the third side

We apply the triangle inequality theorem here

To get the third side, then the sum of the lengths of the two must be greater than the measure of the third side

let us call the third side x

Then;

5 + 5 > x

10 > x

The highest whole number before 10 is 9: so it is the greatest possible whole number the base of the isosceles triangle can have

Roman created the following table to represent the balance of his loan, y, over a period of months, x. The equation for the line of best fit of Roman's table of dadt is y= -200.22x + 5,014.20.​

Answers

Answer: extrapolation, and 25 months

Step-by-step explanation:

I took the Plato test and got it right, but if you want to know. Interpolation means based on the numbers given you could see the answer, extrapolation means you have to go farther than the last plot point given to get your answer. Which you do since it does not go past 12 months.

The second answer you can roughly get by pluging in each of the choices in the equation for x

For example: y=-200.22(25)+5015.20

That should give you an answer pretty close to zero so there is your answer

The New England Revolutions are having a charity soccer event for which tickets cost $18 per person. However, the ticket agency adds a fixed fee to every order so a person who orders 5 tickets pays $93.

Answers

Let as consider, we need to find the fixed fee.

Given:

Cost of each ticket = $18

Number of tickets = 5

Total cost = $93

To find:

The fixed fee.

Solution:

Let x be the fixed fee..

Cost of 1 ticket = $18

Cost of 5 ticket = $(5 × 18)

                         = $90

Total cost 5 tickets = Fixed fee + Cost of 5 tickets

[tex]93=x+90[/tex]

[tex]93-90=x[/tex]

[tex]3=x[/tex]

Therefore, the fixed fee is $3.

a,3x+2,b form an arithmetic sequence.if the common difference is 2x - 1 , what is A equal to?​

Answers

Answer:

x + 3

Step-by-step explanation:

3x+2 is the 2nd term

2x-1 is the commind difference (d)

so you just need to substract it

3x+2

-(+2x-1) -------transpose -2x+1

3x+2

-2x+1

---------

x+3

Answer:

a is equal to x + 3

Step-by-step explanation:

Arithmetic Sequences

The arithmetic sequences are identified because any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.

We are given the sequence:

a, 3x+2, b

And the common difference is 2x-1

Subtracting the second and the first terms:

3x + 2 - a

We can find the common difference since it's given:

3x + 2 - a = 2x - 1

Solving for a:

- a = -3x - 2 + 2x - 1

- a = -x - 3

a = x + 3

a is equal to x + 3

Determine whether the inverse of f(x)=2x2−5
is a function. Then find the inverse.

Answers

Answer:

Not a function. The inverse is

[tex]y = \sqrt{ \frac{x + 5}{2} } [/tex]

and

[tex]y = - \sqrt{ \frac{x + 5}{2} } [/tex]

Step-by-step explanation:

Any even-degree polynomial functions that are inverted will not be a function.

[tex]f(x) = 2 {x}^{2} - 5[/tex]

Let y = f(x)

[tex] y = 2 {x}^{2} - 5[/tex]

To proceed the inverse, swap the x-term and y-term.

[tex]x = 2 {y}^{2} - 5[/tex]

Convert into function form.

[tex]x + 5 = 2 {y}^{2} \\ 2 {y}^{2} = x + 5 \\ {y}^{2} = \frac{x +5 }{2} [/tex]

The reason why inverted even-degree polynomial function cannot be a function because the inverse graph doesn't pass line test.

Thus the answer is

[tex]y = \sqrt{ \frac{x + 5}{2} } \\ y = - \sqrt{ \frac{x + 5}{2} } [/tex]

Yea I can help you with these problems I’ve done this a long time ago and so far I remembered how to do this. So for number 1. X=4 in this problem so we need to substitute x into 4 and recreate this expression: 4+1=5, and yes it is a solution. As for number 2, w would equal to 2 so 13-2=10 isn’t a solution because 13-12 is actually 11, so this is a false. Now number 3, v would equal to 10 so you’d have to replace 10 into this expression; so it’s going to be 2(10)=12 which isn’t a solution because 2 times 10 equals to 20. Now for number 4, p would have to equal to 7, here is the expression; 14/7=2, is a solution because if you’re going to check it do 7(2) and it would actually equal to 14 so yes it is a solution. Now for number 5 you would have to equal w to 3 so do this in an expression; 8+3=11, and yes that is a solution because you can check it as 11-3 which would equal to 8. Now for number 6 t would have to equal to 5 so replace t into 5 which the expression is going to be; 4(5)=20 so yes it is a solution because you can check it by doing 20/5=4. Now for number 7 s would have to equal to 3 so in this expression would have to be; 12/3=4 and yes that is a solution because you can check it by doing 3 times 4 which would equal to 12. Now for the last problem 8, d would have to equal to 8 so you replace d into 8 which the expression is going to be; 6+8=14, it’s not going to be 6+8=15 because it doesn’t equal to that since if you want to check the right answer just subtract 14 by 8 and you would get 6. So the last problem isn’t going to be a solution.

expand 3a(2b+c) .............​

Answers

Answer:

We know that the distributive property says this:

a(b+c) = ab + ac

If we apply this to our case, we can put

3a(2b+c) = 3a * 2b + 3a * c

When we multiply numbers and letters, we should multiply both of them:

3a * 2b + 3a * c = 3*2*a*b + 3*a*c = 6ab +3ac

We can use this when we find a number multiplied by a parenthesis..

Answer:

6ab + 3ac

Step-by-step explanation:

3a(2b) + 3a(c)

Un camion lleva 200 cajas. Cada caja contiene 20 paquetes de cafe de un cuarto de kilo. ?Cuantos kilos de cafe lleva el camion?

Answers

Answer:

1000 cajas

Step-by-step explanation:

De la pregunta anterior, sabemos que:

Un camión lleva 200 cajas.

Cada caja contiene 20 paquetes de café de un cuarto de kilo.

Esto significa

1 caja = 20 paquetes (1/4 kilo) de café

1 caja = paquetes de 5 kilos de café

Ya que tenemos 200 cajas en el camión

1 caja = 5 kilo

200 cajas = x

Cruz multiplicar

x = 200 × 5 kilo

x = 1000 kilos

Por tanto, los kilos de café que puede transportar el camión son 1000 kilos.

Answer:

60

Step-by-step explanation

Okay, uh... this is gonna be confusing to explain.

So a hexagon's angles add up to 720. This means, we can find each angle's supplementary angle by subtracting each value we know away from the total.

So, we know the inside angle of angle 6 is 90.

So: 720-90=630

Now, typically, you would divide by the remaining angles, but we have basically 2 angles of different values since 1, 2, and 3 are equal, and 4 and 5 are equal.

However, we know that 1, 2, and 3 are 10 degrees less than 4 and 5. So if we "add" 10 degrees to each of those angles we get:

10*3=30

630-30=600

Now we made it as though each angle (1-5) is equal. So now we divide by 5.

600/5=120

This means the supplementary of angles 4 and 5 is 120, so we subtract that value from 180 since a straight angle is 180.

180-120=60

Now, to check this we reverse it.

(120*2)+(120*3)+(10*3)+(90)=

240+360+30+90=

600+30+90=

600+120=

720.
