Answer:
y = 5/2x -4
Step-by-step explanation:
y = mx + c
Slope m = 5/2 and c = -4
y = 5/2(x) - 4
Multiply each term by 2
2y = 5x - 8
Answer:
Step-by-step explanation:
The construction of the figure gives us three right triangles, where we can apply Pythagora's Theorem.
I have added two variables to the image in the picture attached.
On the triangle with sides y,h,16 we have:
On the triangle with sides h,z,25 we have:
Equating :
On the bigger triangle with sides y,z,16+25=41 we have:
Adding this last equation with [1]:
Simplifying:
Operating:
Dividing by 2:
Taking square root:
y=20
To enter the number in the required format:
Step-by-step explanation:
When deciding where to put an ordered pair on a graph its important to understand how ordered pairs work.
An ordered pair is split up into to pieces
(x,y) or number example (3,5)
When graphing the x coordinate will fall on your horizontal line or the line that looks like the horizon.
When graphing the y coordinate it will fall on your vertical line or the line that goes right up into the sky like a rocket.
To graph (3,5)
Go to the right 3 and up 5
Sometimes helps to use both fingers to keep your spot. Slide both fingers until they collide and that's where you would plot your point!
Hope this helps if you have an questions just comment and ill try to explain further.
The volume of a pyramid is equal to 1/3 multiplied by the base of the pyramid multiplied again by the height. In this case, the base of the pyramid is a square. Hence the area should be s^2. The volume now becomes V = 1/3 * s^2 * h = 1/3 * s^2 * 9 = 48. length,s is not equal to 4. Answer is A. 4 inches.
There were 37 student tickets and 52 adult tickets
Step-by-step explanation:
Let x be the number of student tickets and y be the adult tickets
Then
According to given statement that total 89 tickets were sold
x+y=89 Eqn 1
And
$5 for an adult ticket and $3 for student ticket ,and total cost $371
3x+5y=371 Eqn 2
From eqn 1
Putting in eqn 2
Subtracting 267 from both sides
Dividing both sides by 2
Putting y=52 in eqn 1
Hence,
There were 37 student tickets and 52 adult tickets
