Answer:
y=-4x-6
Step-by-step explanation:
y=mx+b, where m is the slope and b is the y-intercept
Slope is given as -4, so:
y=-4x+b
To find b, sub in the point we were given (-2,2):
2=-4(-2)+b
2=8+b
b=2-8=-6
So we have: y=-4x-6
Answer:
Step-by-step explanation:
We have been given that a series of 3 separate, adjacent tunnels is constructed through a mountain. Its length is approximately 25 kilometers.
Each of the three tunnels is shaped like a half-cylinder with a radius of 5 meters.
Since we know that volume of a semicircular or a half cylinder is half the volume of a circular cylinder.
, where,
r = Radius of cylinder,
h = height of the cylinder.
Upon substituting our given values in volume formula we will get,
Therefore, the volume of earth removed to build the three tunnels is .
Answer:
b.18
Step-by-step explanation:
18/4=4.5
4.002.
The steps for this are as follows:
Set up the equation, 24.012 divided by 6.
Six cannot go into 2, so the first number is going to be zero. Drop down the 4 to make the number 24, and divide by 4. This makes the second number 4.
Next you have to make sure you place the decimal up to the final answer and bring down the zero. Since six can’t be divided into zero, the next number above is 0. Bring down the one, again can’t be divided so put a zero. Then bring down the two to make the number twelve and bring up the two.
Here’s a visual for better clearance:

For example if you have 3 adults you would multiply :
$85.50 x 3 = ?
Or
$85.50 + $85.50 + $85.50 = ?
