Answer:
x=4, y=0. (4, 0).
Step-by-step explanation:
3x-4y=12
x=-2y+4
-----------
3(-2y+4)-4y=12
-6y+12-4y=12
-10y=12-12
-10y=0
y=0/-10=0
x=-2(0)+4=0+4=4
Answer:
Step-by-step explanation:
if x=-2y+4
3x-4y=12 becomes
3(-2y+4)-4y=12
-6y+12-4y=12
-10y+12=12
-10y=0
y=0
since x=-2y+4
x=-2(0)+4
x=4
so the solution is the point (4,0)

Answer:
Distributing
Step-by-step explanation:
The first step is to get the x's out of parenthesis. Distribute the 2 into the (x-4), and the -3 into (x+2).
ex. 2(x-4) = -3(x+2)
distribute: 2x-8= -3x+6

Solve the equation for y. Show work.
6x−4y=24
Answer:
y = -3/2x + 6
Step-by-step explanation:
We won't be able to figure out Y in number form, since we have a second variable, but we can figure it out in terms of X.
First, we have to subtract 6x from both sides
( -4y = -6x + 24 )
Then we have to divide both sides by -4
( y = -3/2x + 6 )
This is our final answer in terms of x
In the triangle below, what is the length of the side opposite the 30 degree angle?
Answer:
A. 3/2
Step-by-step explanation:
To find the lenght of the side opposing the 30° angle, you need to use trigonometry, since it's a right-angled triangle. You have your 30° angle and you have the side beside : therefore, you can use the sine :
sin(30) x 3 = ?
0,5 x 3 = ?
1,5 = ?
1,5 = 3/2

The map shows different events at a ski resort. Each unit of the coordinate plane represents 1 mile.
What is the distance between snow tubing and the ski lift?
A. 6 miles
B. 7 miles
C. 13 miles
D. 17 miles
Answer: B
Step-by-step explanation:
Let us write down the coordinates of the snow tubing and the ski lift.
Ski Lift = (3 , -4)
Snow Tubing = (3, 3)
We want to find the distance, which can be found by subtracting their y coordinates from each other.
-4 - 3 = 7
or
3 - (-4 ) = 7
If you can, you can always count the squares away each point is from each other. The answer is B - 7 miles.

Jake spent a three-day weekend on the lake. On Saturday, he rented a pontoon boat for three hours and paid $435. On Sunday, he rented the same boat for five hours and it cost him $190 more than it di the day before. If he rented the same boat on Monday for just two hours, find the total cost to rent the boat for three days.
Answer:
1400
Step-by-step explanation:
There is a flat fee involved, which is the y-intercept of the line.
The line eats the points:
(3, 435)
and
(5, 625)
the slope is 190/2 = 95
B = y - mx = 435 - (95)(3)
= 435 - 285
= 150
The linear function is:
y = 95x + 150
So for x=2, it will cost
95(2) + 150 = 190 + 150 = 340
435 + 625 + 340 = 1400
The total cost to rent the boat for three days is $1400.
Given that, on Saturday, he rented a pontoon boat for three hours and paid $435.
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The cost for the rented a pontoon boat for five hours is 435+190 = 625
The coordinate points are (3, 435) and(5, 625)
The slope is m = (625-435)/(5-3)
= 190/2 = 95
Now, b = y - mx = 435 - (95)(3)
= 435 - 285 = 150
So, the linear function is y = 95x + 150
So for x=2, it will cost
95(2) + 150 = 190 + 150 = 340
Total cost = 435 + 625 + 340 = 1400
Therefore, the total cost to rent the boat for three days is $1400.

The Skateboard club has 2 different colors of skateboards blue and red. Can you find the number of skateboards of each color, if the total number of skateboards is 15, and their product is 44?
Answer:
The number of skateboards of each color is 11 and 4
Step-by-step explanation:
Let x represent blue skateboards and
y represent red skateboards.
From the question, the total number of skateboards is 15, that is,
x + y = 15 ...... (1)
and their product is 44, that is,
xy = 44 ...... (2)
From equation (1),
x + y = 15
We can write that
x = 15 - y ...... (3)
Substitute this into equation (2)
xy = 44
(15-y)y = 44
15y -y² = 44
Then,
y² - 15y + 44 = 0
Solve quadratically
y² -4y -11y + 44 = 0
y(y-4) -11(y-4) = 0
(y-11)(y-4) = 0
y-11 = 0 OR y-4 = 0
y = 11 OR y = 4
Put the values of y into equation (3) for x
x = 15 - y
When y = 11
x = 15 - 11
x = 4
and when y = 4
x = 15 -4
x = 11
(4,11) and (11,4)
It is either 4 blue and 11 red skateboards OR 11 blue and 4 red skateboards.
Hence, the number of skateboards of each color is 11 and 4.

Answer:
5,720,000 Sq Feet.
Step-by-step explanation:
They are asking the Area of a Trapezoid
Equation =( base + base / 2) x height
Lets first set it up. We know that A-B is 200 feet. & D-C is 260. They are both the bases.
So if you multiply them (200 x 260) You will get 52000.
Now we divide that by 2. (52000 / 2 = 26000)
Now it says the straight line is 220. I think this refers to the height.
Now we multiply 26000 x 220. Which is 5720000.
Its a pretty big number, but that is the answer! :)

The width of a rectangle is x. Its length is 3x. How long is the diagonal of the rectangle? Express your answer in simplified radical form.
Answer:
The length of the diagonal is x√10
Step-by-step explanation:
Here, we want to find the length of the diagonal
The diagonal will represent the hypotenuse of a triangle formed with the width and length of the triangle being the measure of the other sides
Mathematically, we then apply Pythagoras’ theorem to get this
we have this as that the square of the diagonal equals the sum of the squares of the two other sides
d^2 = x^2 + (3x)^2
d^2 = x^2 + 9x^2
d^2 = 10x^2
d = √(10x^2)
d = x√10
