Write equations for the vertical and horizontal lines passing through the point (8,-9)

Mathematics

Lilit [14]3 years ago
7 0

Answer:

x = 8 and y = - 9

Step-by-step explanation:

The equation of a vertical line is x = c

Where c is the value of the x- coordinates the line passes through

The line passes through (8, - 9) with an x- coordinate of 8, thus

Equation of vertical line is x = 8

The equation of a horizontal line is y = c

Where c is the value of the y- coordinates the line passes through

The line passes through (8, - 9) with y- coordinate - 9, thus

The equation of the horizontal line is y = - 9

An ice cream cone has a diameter of 7 cm and a height of 13 cm. How many milliliters of melted ice cream can it hold? (1 cm3 hol
allsm [11]
This question is asking for the volume of the cone.
The formula is 1/3π r²h where r is radius and h is height.
First we must find the radius by dividing the diameter in half, giving us 3.5
Now we plug our values into the formula like this:

1/3 π r²h
1/3 π3.5² 13

This gives us the answer of 166.76mL or 166.8mL depending on how you want to round it.

Hope this helps :)

What’s the length of a box with a volume of 720 cubic inches, a width of 15 inches, and a height of 4 inches? (Hint: Isolate the
Tom [10]

Box volume = height * width * length.  In this problem we want the length, so we solve the given equation for length:

                 720 in^3

length = -------------------- = 12 in

               (15 in)(4 in)

The box is 12 inches long.

Solve the system algebraically. Check your work.
Luden [163]

answer.

Answer:

x=2 and y=0 is the required result.

Step-by-step explanation:

We have been given system of equations:

5x+2y=105x+2y=10     (1)

And 3x+2y=63x+2y=6      (2)

We will use elimination method:

Multiply 1st equation by 3 and 2nd equation by 5 we get:

15x+6y=3015x+6y=30      (3)

15x+10y=3015x+10y=30      (4)

Now subtract  (4) from (3) we get:

-4y=0−4y=0

y=0y=0

Now, put y=0 in (1) equation:

5x+2(0)=105x+2(0)=10

5x=105x=10

x=2x=2

Hence, x=2 and y=0
