What is the solution to the system of equations below?

2 x minus y = 10 and y = negative one-half x + 5
PLEASE HELP

Answer:

its 25

Step-by-step explanation:

if you divide 125 and 5 you get 25

then if you divide 170 and you get 21.25 but you want to round it to 25

hope this helps plz let me have brainliest

The fee per race is $15, while the membership fee is $50

A linear equation is given by:

y = mx + b;

Where y, x are variables, m is the slope of the line and b is the y intercept.

Let x represent the number of race and y represent the total money, b is the membership fee and m is the pay per race, hence:

One racer paid a total of $125 after 5 races, hence:

125 = 5m + b   (1)

A second racer paid a total of $170 after 8 races, hence:

170 = 8m + b      (2)

Solving equation 1 and 2 simultaneously gives:

m = 15, b = 50

Hence the fee per race is $15, while the membership fee is $50

Answer:

x = 3

x - 2y = -25

Step-by-step explanation:

Since y = 4x + 2 put (4x + 2) into the first equation in place of y:

6x - (4x + 2) = 4

To get rid of the parenthesis change 4x to -4x and 2 to -2:

6x - 4x - 2 = 4

If you combine the x’s you will now have only 2x

2x - 2 = 4

To get x by itself we add 2 to both sides

2x = 6

Divide by 2 on both sides:

x = 3

_______________________________

For the last equation (x - 2y) we put (4x + 2) in place of y again:

x - 2[4x + 2]

We know the value of x already:

3 - 2[4(3) + 2]

Now solve for the things in parenthesis:

3 - 2(14)

3 - 28

Subtract to get the answer:

-25

Answer:

[tex]Point Form:(1,2)\\Equation Form:x=1,y=2[/tex]

Step-by-step explanation:

Let's solve your system by substitution.

[tex]6x-y=4;y=4x+2x-2y[/tex]

Step: Solve 6x−y=4for y:

[tex]6x-y=46x-y+-6x=4+-6x[/tex]

[tex]-y=-6x+4[/tex]

[tex]\frac{-y}{-1} =\frac{-6x+4}{-1}[/tex]

[tex]y=6x-4[/tex]

Step: Substitute 6x−4 for y in y=6x−2y:

[tex]y=6x-2y\\6x-4=6x-2(6x-4)[/tex]

[tex]6x-4=-6x+8[/tex]

[tex]6x-4+6x=-6x+8+6x\\12x-4=8\\12x-4+4=8+4[/tex]

[tex]12x=12\\\frac{12x}{12} =\frac{12}{12}[/tex]

Step: Substitute 1 for x in y=6x−4:

[tex]y=6-4\\y=(6)(1)-4\\y=2[/tex]

Answer:

[tex]x=1 , y=2[/tex]

Answer:

It should be -8

Step-by-step explanation:

Answer:

Second option

Step-by-step explanation:

It is given that, if the area of the rectangle to be drawn is 10 square units

To find the length of the rectangle

From the figure, we get the length of AB = 2 units

Therefore Area = length * breadth = 10

Therefore length = 10/2 = 5 units

To find the points of C and D

we have B(-1, 3)

Point C is 5 units below the point B

Therefore C(-1, 3-5) = C(-1,-2)

we have A(1, 3)

The point D is 5 units below the point B

Therefore D(1, 3-5) = A(1,-2)

Therefore the correct answer is option 2.

Answer:

B. C(-1, -2), D(1, -2)

Step-by-step explanation:

So we know the area of the shape is 10 square units, A and B are 2 units apart, what we need to do is multiply that by 5, so we would have to go 5 units down, which would get you down to (-1, -2), and (1, -2). So that's your Answer.

Answer:

-8a + 3b +7   (Answer A)

Step-by-step explanation:

Let's take all the like terms and put them together!

There's:

-2b and 5b

-6a and -2a

7

Let' add all of them to each other!

-2b + 5b is 3b

-6a + -2a is -8a

7 remains 7

Since a is the first letter of the alphabet, we would order it in alphabetical order.

-8a + 3b +7

The answer is A

1 day: 122,440

I’m not sure if this is exactly right, my brain gave out half way. Someone check my answer pls

Step-by-step explanation:

3 hours:   3 x 60= 900

                 900 divided by 20= 450

                    450 x 85 = 38,250

1 day:       24 x 60 = 1440

                 1440 x 85 = 122,440

Answer:

3 hours: 38,250

1 day: 122,440

Answer:

B. 35 dollars

Step-by-step explanation:

So first you have to subtract 20 from 160 because that is the only cost that we definitely know. 160-20=140

Then you have to divide 4 from 140 because the sweaters cost the same amount and she bought 4 of them and 140 divided by 4 is 35

So each sweater coat 35 dollars

Answer:

-512

Step-by-step explanation:

The laws of exponents state that multiplying two exponents together of the same base allows you to add the exponents. Raising an exponent to another power allows you to multiply the exponents. In this case. you have [tex](-2)^3*((-2^3))^2[/tex]. First, you  take the second term, or [tex]((-2^3))^2[/tex] and simplify it. Since you're raising an exponent to another exponent you have [tex](-2)^(3*2)[/tex], or [tex](-2)^6[/tex]. Now, you multiply by [tex](-2)^3[/tex]. Since they both have the same base, you can add the exponents to get [tex](-2)^9[/tex]. Since [tex](-2)^9[/tex] is raised to an odd exponent, you know you're answer is going to be negative. [tex]2^9[/tex] is 512, so that negative would be -512. If you're looking for an expression for this, you can write [tex](-2)^9[/tex]

Answer:

10,080 (assuming that Juliet gets 2% interest each month)

Step-by-step explanation:

The first step would be to figure out what's 2% of 9000 (180)

and then do 180*6 because she is investing for 6 months (1080)

and then add the 9000 and interest 1080 and you get 10,080

(for further questions please be more informative its important to know how much is gained per a period of time for example: if it where 2% interest every 2 months the answer would be very different )

please inform me if I made a mistake.
