Answer:
the answer is 8.
trust me
Answer:
The equation line is y + 3x = -10.
Step-by-step explanation:
In this question, first we have to find the slope of the equation:
The formula which we use to find the slope is:
slope = m = (y2-y1)/(x2-x1)
m = (8 + 1) / (-6 + 3)
m = 9 / (-3)
m = -3.
Now, put the value of slope and the first points (-3, -1). You can use any of the given points:
y - y1 = m(x - x1)
y + 1 = -3(x + 3)
y + 1 = -3x - 9
y + 3x = -10
This is the eqution line.
You can check if this line is true or not by putting the other points in this equation which will give the same points like,
y + 3(-6) = -10
y - 18 = -10
y = 8
So, we get the same old points (-6, 8) which we have given.
20x + 11y = 37
4x + 3y = 13
Enter the correct answer.
Answer: x= -2 and y=7
Step-by-step explanation:
4×20x+11y=37
20×4x+3y=13
Using elimination method
80x+44y=148
80x+60y=260
-16y/-16=-112/-16
Y=7
Substitute for Y in equation (1)
20x+ 11(7)=37
20x+77=37
20x=37-77
20x/20= -40/20
X= -2
therefore, x=-2 and y=7
17,148.59 cubic millimeters
B.
267.95 cubic millimeters
C.
2,143.57 cubic millimeters
D.
1,071.79 cubic millimeters
Answer:
C.
Step-by-step explanation:
Use the equation V=4/3(3.14)r^3.
You gave me the diameter of 16 millimeters so just divide it by 2 to get a radius of 8 then input it for the r.
V=4/3(3.14)8^3
Then just multiply it to get the answer of 2144.66058 and C. is the closest to this answer and that is why it is correct.
The answer is 113/90.
