Y=5x+42
subtract 5x from both sides
-5x+y=42
multiply by -1
5x-y=-42
In standard form, Ax+By=C, the variable A cannot be a negative. However, this is not an option so go with c.
Answer:
10:1
Step-by-step explanation:
Answer:
240, 1800, 2040
Step-by-step explanation:
First find the surface area of the shape - base = 3 x 15 x 2 + 40 x 15 + 40 x 3 x 2 = 930 m ^2
Now find the area of base = 40 x 15 = 600
Now, the cost of painting = 10 pounds for 25 m^2. SO here cost = 600 / 25 x 10 = 24 x 10 = 240 pounds.
Now cost of tiles = 600 x 3 = 1800
Total cost = 1800 +240 = 2040
1) slope is (8-1)/(4-(-6))=7/10
2) slope is (3-5.2)/(3.25-(-42.25))=-2.2/45.50=-22/455
3) the slope of 1 means the line is inclined to the horizontal axis at an angle of 45 degrees. There are an infinite number of such parallel lines, but only one y=x passes through the origin.
When you subtract the length of the base from the length of the side, you get
(ax+9) - (4x+b) = (a-4)x +(9-b)
