The equation is in slope-intercept form, so you can read the equation to find the y-intercept is (0, -1).
Since the slope is -1/2, the graph goes <em>up</em> 1 unit for each 2 units to the <em>left</em>. The x-axis is up 1 unit from the y-intercept, so the x-intercept is 2 units to the left of x=0, at (-2, 0).
The graph is the line that goes through the points (0, -1) and (-2, 0).
_____
If you like, you can put the equation into intercept form, which shows you both the x- and y-intercepts at once. That form is ...
... x/a + y/b = 1
where <em>a</em> and <em>b</em> are the x- and y-intercepts.
If we add 1-y to the given equation, we have ...
... 1 = (-1/2)x - y
... 1 = x/(-2) + y/(-1) . . . . intercept form
Hi!
Volume = Length x Width x Height
Therefore, V = 5 x 5 x 10
5 x 5 x 10 = 25 x 10 = 250 .
Your answer is D, the last one.
Hope this helps! :D
Answer:
P = 2(4x - 5)
Step-by-step explanation:
The formula for solving the perimeter of a rectangle is:
P = 2(L + W), or
P = 2L + 2W
Given the length (L) = 3x - 7, and width (W) = x + 2:
Substitute these values into the perimeter formula in order to solve for x and determine the actual dimensions of the given rectangle.
P = 2L + 2W
Use the distributive property of multiplications (over subtraction and addition, respectively), and distribute 2 into each parenthesis:
P = 2(3x - 7) + 2(x + 2)
P = 6x - 14 + 2x + 4
Combine like terms:
P = 8x - 10
Factor out the common term to reduce the algebraic expresssion into its simplest form:
P = 2(4x - 5)
Therefore, the perimeter of the given rectangle in its simplest form is:
P = 2(4x - 5).
