Solve
Answer:
no solution
Step-by-step explanation:
3х – 5 = 3(х – 1)
Distribute
3x -5 = 3x -3
Subtract 3x from each side
3x -5-3x = 3x -3 -3x
-5 = -3
This is not true so there is no solution
Answer:
3x-5=3x-3
3x-3x-5+3=0
x-2
x=2
substituting x=2
3x-5=3(x-1)
3×2-5=3(2-1)

do a y=mx+b equation
Answer:
y=-2x
Step-by-step explanation:
The y-intercept is 0 so b is 0
and it is going down 2 right 1 so it is -2/1 -2/1 =-2 so it is y= -2x
Answer:
y = -2x + 0
Step-by-step explanation:
y = mx + c
m = gradient and c = y intercept ( the point where the line intercepts the y axis)
Firstly, we can tell the gradient is negative because it has a negative slope (sorta like down a hill) where as x increases y decreases.
To calculate the gradient you use the equation y/x
Pick anywhere on you graph and measure. I have taken from (0,0) to (0,-4) for y and (0,-4) to (2,-4) for x.
Next subtract them (0,-4) - (0,0) = 0,-4. Then take that - 4 for y
Next subtract for them for x (0,-4) - (2,-4) = 0- 2 and -4 -(-4)
= -2 and -4 + 4 = 0
= -2
So y = -4 and x = -2
y/x = 4/2 = 2
Because we know our gradient is negative add a minus and we get our gradient as -2
For y intercept simply find where the line crosses through the y axis, which in this question happens to be 0
answer = -2x + 0

Find the coordinates of the centroid of the triangle with the given vertices.
S(5, 5), T(11, -3), U(-1, 1)
The coordinates of the centroid of the triangle STU is: (3, 1).
Recall:
The centroid of a triangle is the point of concurrency of all the medians of a triangle.The centroid of triangle ABC that is shown in the image attached below is point G.The formula for finding the coordinate of the centroid of a triangle is: [tex]\mathbf{(x, y) = (\frac{x_1 + x_2 + x_3}{3}, \frac{y_1 + y_2 + y_3}{3})}[/tex]Thus, given the vertices of a triangle as: S(5, 5), T(11, -3), U(-1, 1)
Let,[tex]S(5, 5) = (x_1, y_1)\\\\T(11, -3) = (x_2, y_2)\\\\U(-1, 1) = (x_3, y_3)[/tex]
Plug in the values[tex](x, y) = (\frac{5 + 11 +(-1)}{3}, \frac{5 + (-3) + 1}{3})\\\\(x, y) = (\frac{15}{3}, \frac{3}{3})\\\\\mathbf{(x, y) = (3, 1)}[/tex]
Therefore, the coordinates of the centroid of the triangle STU is: (3, 1).

Step-by-step explanation:
For the constant of proportionality, you'll want to basically find the slope.
The constant of proportionality, k, is defined as:
[tex]k=\frac{y}{x}[/tex]
Thus, we can do this for all three values and reach a conclusion:
[tex]k=\frac{224}{8}[/tex]
[tex]k=\frac{280}{10}[/tex]

Answer:
You can use substitution, elimination, or graphing.
Step-by-step explanation:
So what I would do, is using elimination because you have two variables that are the same, what I mean is that you have two -3y's, So, take one equation, lets do the top one, and multiple the whole thing, yes, the WHOLE THING meaning both sides by -1. This will give you -6x+3y= -12. The negative turns to positive because you multiply the -3y by -1. Notice how you have a +3y in the top equation now and a -3y in the bottom one. This is why the method is called elimination, you can cross out the +3y and -3y and combine both equations. You now have -2x=12. Divide both sides by -2, x=-6. Plug -6 in the first equation, you get 6(-6)-3y=12 which goes to -36-3y=12. Add 36 on both sides, you get -3y=48. Divide both sides by -3, you get y=-16. Oh yeh, plug y into one of the equations and solve for x, i forgot to say that.

Number 16 plz and don't answer if you don't know I'll report you
Answer:
a = 5 seconds and b = 50 inches c = No, because it starts at 50 inches and only goes down after that. This means it will never be at 120 inches.
Step-by-step explanation:
A. Solve it as a quadratic equation where h = 0 (because it will be 0 inches above the water).
0 = - 16t^2 + 70t + 50
0= -2(8t^2 - 35t -25)
0= -2(t - 5)(8t + 5)
Since the amount of time has to be positive, t - 5 = 0, so t = 5 seconds
B. Substitute t = 0 into the equation.
h = -16(0)^2 + 70(0) + 50
h = 0 + 0 + 50
h = 50 inches
C. It's diving, so it's only going down and won't reach 10 feet.

[tex]x=10+y\\\\ x+y=64[/tex]
Part B)
There are 37 students in the drama club.
And there are 27 students in the yearbook club.
Step-by-step explanation:
We know that there are 64 students in total in a drama and yearbook club.
The drama club has 10 more students than the yearbook club.
We will let x represent the number of students in the drama club and y represent the number of students in the yearbook club.
Part A)
Since the drama club (x) has 10 more students than however many the yearbook club (y) has, we can write:
[tex]x=10+y\\[/tex]
And since there are in total 64 students, x plus y must equal that sum. So:
[tex]x+y=64[/tex]
Part B)
We can substitute the first equation into the second:
[tex](10+y)+y=64[/tex]
Combine like terms:
[tex]2y+10=64[/tex]
Subtracting 10 from both sides:
[tex]2y=54[/tex]
Dividing by 2:
[tex]y=27[/tex]
So, the amount of students in y or the yearbook club is 27 students.
Since the drama club has 10 more, there are 37 students in the drama club.
Consider the equations y = 2x - 3 and y = 3x - 6. Solve the system of equations by completing the table to find an ordered pair that satisfies both equations.
A) (0, 3)
B) (1, -1)
C) (2, 2)
D) (2, 2)
Answer:
2,2
Step-by-step explanation:
Equations are all good
The ordered pair (2, 1) satisfies the given equations. Therefore, the answer is option (C).
To solve the system of equations y = 2x - 3 and y = 3x - 6, we need to find an ordered pair (x, y) that satisfies both equations.
We can do this by completing the table of values for each equation and finding the values of x and y that make both equations true.
For the equation y = 2x - 3, we can complete the table as follows:
x: -1, 0, 1, 2, 3
y: -5, -3, -1, 1, 3
For the equation y = 3x - 6, we can complete the table as follows:
x: -1, 0, 1, 2, 3
y: -9, -6, -3, 0, 3
From these tables, we can see that the ordered pair (2, 1) satisfies both equations.
Therefore, the answer is (2, 1).

Answer: I think the answer is B
Step-by-step explanation:
8(x-4) = 8(1-4) = 8-32
2(4x-16) =2(4*1-16) = 8-32
8(x-4) = 8(2-4) = 16-32
2(4x-16) = 2(4*2-16) = 16-32
Answer:
B. Infinitely many solutions.
Step-by-step explanation:
8(x - 4) = 2(4x - 16)
^--This is the original equation.
If we replace x with 1...
we have the same equation, but we add an extra set of brackets. (You'll see why in a second)
8(1 - 4) = 2{4(1) - 16}
1 - 4 = -3
We start by subtracting 4 from 1. When using positive numbers, we can't do this, however. This gets us to -3. leave it in the parenthesis though!
8(-3) = 2{4(1) - 16}
4(1) = 4
Now, the reason we made an extra set of brackets is because 4x is asking you to multiply 4 by x. but as a number, you have to make an extra set of parenthesis to show that. 4 x 1 = 4 so it stays as a 4.
8(-3) = 2(4 - 16)
^-- Now, we are given this new equation. We'll move away from 8(-3) for just a second, to finish the other parenthesis. But still don't remove the parenthesis for 8(-3)!
4 - 16 = -12
We know that 4-16 would also not be possible with positive numbers, but for this equation, as said before.. you're using negative numbers. so 4 - 16 = 12
8(-3) = 2(-12)
^-- And again, we have a new equation. 8(-3) = 2(-12). Don't remove the parenthesis, as I have said before.
8(-3) = -24
Again, the equation shows with parenthesis, it wants us to multiply. Now we take 8, and multiply it by -3. This is a bit tricky, as it is with negative numbers. But in the end, you should have -24.
-24 = 2(-12)
^--The equation becomes -24 = 2(-12). We'll have to multiply again, so keep the parenthesis.
2(-12) = -24
2(-12) Is also asking you to multiply, so now we do the same as before, which again, is a bit tricky because we are using negative numbers. You should end up with -24 though.
-24 = -24
^--Now, you have -24 = -24. This is true since both are the same number.
8(x - 4) = 2(4x - 16)
^-- Here's our wonderful equation again! Let's replace X with a 2 this time!
If you don't understand, read the tips from above to understand what I'm doing in the following equations!
8(2 - 4) = 2{4(2) - 16}
2 - 4 = -2
8(-2) = 2{4(2)-16}
4(2) = 8
8(-2) = 2(8 - 16)
8 - 16 = -8
8(-2) = 2(-8)
8(-2) = -16
-16 = 2(-8)
2(-8) = -16
-16 = -16
And again, we get the same two numbers!
Hope I helped! <3
