Answer:
The x-intercept would be 9 and the y-intercept would be -18/5
Step-by-step explanation:
In order to find this we need to first find the slope. To do that we use the two points and the slope equation.
m (slope) = (y2 - y1)/(x2 - x1)
m = (-2 - -6)/(4 - -6)
m = 4/10
m = 2/5
Now that we have the slope, we can use that and either point to find the equation of the line in standard form.
y - y1 = m(x - x1)
y + 6 = 2/5(x + 6)
y + 6 = 2/5x + 12/5
-2/5x + y + 6 = 12/5
-2/5x + y = -18/5
-2x + 5y = -18
Now that we have this, we can find the intercepts through using 0s. First, we put a zero in for y to find the x intercept.
-2x + 5y = -18
-2x + 5(0) = -18
-2x = -18
x = 9
Therefore the x intercept is 9.
We find the y-intercept by doing the opposite. We put a 0 in for x.
-2x + 5y = -18
-2(0) + 5y = -18
5y = -18
y = -18/5
Answer: B
The letters have the same positions in the figure names.
Answer:
the answer is A
Step-by-step explanation:
Answer:
y = 6
Step-by-step explanation:
If the slope of a line is zero, then it is a horizontal line. This means that the line will have a constant y value for all x, hence the equation of the line is y = 6
Answer:
Step-by-step explanation:
Surface area of a cylinder:
S. A. = 2πrh + 2πr²
Volume of a cylinder:
V = πr²h
~~~~~~~~~~~
2(π)(2.5)(x) + 2(π)(2.5)² = π(2.5)²(x)
5x + 12.5 = 6.25x
1.25x = 12.5
x = 10
