Step-by-step explanation:
6x - y =4 and y = 4x + 2. Solve the system and find x - 2y
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

[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]

I need help with this....
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]

The equation 3x + 2 = 29 is modeled below.
Which is the first step in solving the equation for x?
A.
Add two counters to each side.
B.
Add two -1 counters to each side.
C.
Add three x jars to each side.
D.
Remove three x jars from both sides.
Answer:
B
Step-by-step explanation:
The first step to solve the equation is to isolate x. And to isolate x, we need to remove the numerical value, which is +2, by adding two -1's to each side.
Over the next 17 months you have to read more than 68 books. You have to read x books per month. The inequality 17x>68 represents this situation. Solve the inequality to find the number of books you have to read per month.
Answer:
at least five per month
Step-by-step explanation:
if you divide both sides by 78, it will be 4 but you need to read More than 68 so it is five instead
Simplify the expression:
–2b + 7 – 2a + 5b – 6a
A.) –8a+ 3b +7
B.) 8a – 3b + 7
C.) –4a + 7b + 7
D.) 4a – 3b + 7
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

Help mathematicians please
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

In Bicycle Moto Cross (BMX) racing, racers purchase a one year membership to a track. They also pay a fee for each race at that track. One racer paid a total of $125 after 5 races. A second racer paid a total of $170 after 8 races. How much does the track membership cost? What is the fee per race?
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

The length of a rectangle is shown.
If the area of the rectangle to be drawn is 10 square units, where should points C and D be located, if they lie vertically below the line that connects B and A, to make this rectangle?
C(−1, 1), D(1, 1)
C(−1, −2), D(1, −2)
C(−1, 5), D(1, 5)
C(−1, −7), D(1, −7)
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.

Juliet deposited $9,000 into her savings account. The bank offers 2% interest. She invests her money for 6 months. How much money does she have in her account in total, including the interest? Show work.
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 )
