Answer:
y=-3/5x+4
Step-by-step explanation:
Pick any two points the line goes through.
I picked
(0,4) and (5,1)
There are a few ways to do this but ultimately, it’s the same concept. I will use slope-intercept form which for me was always easier.
y=mx+b where m is the slope and b is the y-intercept. The y-intercept is the point where the line crosses the y-axis which in this case is point (0,4) so the b=4.
To find the slope, use rise/run between the two points you chose. Point (5,1) is 3 units UNDER point (0,4) so now we have -3/run because -3 is the “rise”. After you count down 3 units always go right. After going right 5 units, you touch point (5,1). So the “run” is 5. Which means that the slope is -3/5.
m=-3/5 and b=4
So the equation is:
y=-3/5x+4

Answer:
V = 15 in.³
Step-by-step explanation:
The original cylinder has radius r and height h.
V = πr²h
Its volume is 30 in.³, so
πr²h = 30 in.³
The new cylinder has radius (1/2)r and height 2h.
Its volume is
V = π(r/2)²(2h)
V = πr² × 2h/4
V = πr²h/2
πr²h is the volume of the original cylinder, and it is 30 in.³.
V = 30 in.³/2
V = 15 in.³
Answer:
16/49
Step-by-step explanation:
4/7 ÷ 1 3/4
Convert 1 3/4 into an improper fraction
4/7 ÷ 7/4
Find the reciprocal of 7/4 and multiply
4/7 * 4/7
16/49
Hope this helps :)
Answer:
7)
Step-by-step explanation:
The pattern is: add two more than you did before: starting from 2.
It would be:
1, 3, 7, 13, 21, 31, 43, 57
+2 +4 +6 +8 +10 +12 +14
Now use this to answer the questions.
Hope this helped!
Have a nice day!
(it would be nice if you gave me brainliest)
Thx :)
