Let the number = x.
So 2 times x subtracted from 11 is written as 11-2x
The result is 4 more than the number is written as 4 +x
Now you have 11-2x = 4 + x
We can now solve for x.
Add 2x to each side:
11 = 4 + 3x
Subtract 4 from each side:
7 = 3x
Divide both sides by 3:
x = 7/3
Answer:
yeah it is
y is directly proportional to x
proportionality constant is 9
the anwser is 3 0's I believe
Answer:
x - 2y + 1 = 0
Step-by-step explanation:
This line goes through the points (-3, -1) and (3, 2). Going from the first oint to the second, we see that x increases by 6 (this is the 'run') and y increases by 3 (this is the 'rise'). Thus, the slope is m = rise / run = 3/6 = 1/2.
Starting with the slope-intercept form y = mx + b, we get
y = 2 = (1/2)(3) + b, or (after multiplying all terms by 2):
4 = 3 + 2b, or 1 = 2b, or b = 1/2
Then the equation of this line is y = mx + b, or y = (1/2)x + 1/2.
We must put this into standard form. Multiplying all terms by 2 yields
2y = x + 1, or x - 2y + 1 = 0
Answer:
904.9m^3
Step-by-step explanation:
Given data
h= 17 m
r= 6 m
V= 4/3πr^3
substitute
V= 4/3*3.142*6^3
v=4*3.142*216/3
v=2714.688/3
v= 904.9m^3
Hence the volume is 904.9m^3
