Answer: C. 3^5
Step-by-step explanation:
Answer:
y = -1/2x -2
Step-by-step explanation:
The slope-intercept form of the equation for a line is ...
y = mx + b
Comparing this to the equation you are given, you find that the given equation describes a line with a slope of -1/2 and a y-intercept of +6. The parallel line will have the same slope, so m=-1/2.
The given point <em>is the y-intercept</em> of the line you want, so you can use that y-value directly as the "b" in the equation you want:
y = -1/2x -2
Answer:
$ 0.60
Step-by-step explanation:
Answer:
24 m^2
Step-by-step explanation:
There are two areas to consider here: first, the area of the wall, and second, the area of the window. We answer this question by finding these two areas and subtracting the area of the window from the area of the wall.
Wall area: (4 m)(7 m) = 28 m^2
Window area: (2 m)(2 m) = 4 m^2
Net area of wall, to be covered in brick:
28 m^2 - 4 m^2 = 24 m^2
Subtract 15u from both sides
20+2u=-6
subtract 20 from both sides
2u=-26
u= -13
