Answer:
d = 9
Step-by-step explanation:
Calculate the slope of ab then equate to 3.
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (4, 6) and (x₂, y₂ ) = (d, 21)
m =
=
= 3 ( multiply both sides by d - 4 )
3(d - 4) = 15 ( divide both sides by 3 )
d - 4 = 5 ( add 4 to both sides )
d = 9
X + 2y = -6
2y = -x - 6
y = (-x - 6)/2
answer is D. Last one
y = (-x - 6) / 2
A mixed number looks like this: a(b/c)
The improper fraction currently looks like this: (ab/c)
Round the numerator to something you can divide by the denominator. For example, 45 would be rounded to 42. 42/7=6. 6 would be the whole number.
45-42=3. 3/7 is the new fraction.
So the answer for c is 6(3/7)
Do you know how to do d?
Answer:

43
Step-by-step explanation:
Given that:
Total points scored in basketball season, T = 268
Points scored from right handed shots, R = 225
Points scored from left handed shots = 
To find:
To write an equation to describe the situation and find the value of
for left handed shots ?
Solution:
We know that the points can be scored in basketball either by right hand shots or by left hand shots.
In other words, we can say that:
Total points scored in basketball season = points scored from right handed shots + points scored from left handed shots
i.e.

So, the equation is:

Now, let us find the value of
from the above equation:

Number of points scored from left handed shots = <em>43</em>
The volume of the pipe is about 282.6 cubic feet.
First, we need to find the area of each circular cross section and subtract them to find the width of the pipe. The area of a circle is pi(r^2).
pi(3^2) - pi(2^2)
28.26 - 12.56 = 15.7
The width of the pipe is 15.7. Now, multiply that by 18 to find the volume.
15.7 x 18 = 282.6
