8x - 16y = a common factor would be 8...so factor out 8
8(x - 2y)
Answer:
y = -(x-1)^2
Step-by-step explanation:
W=15 subtract 80 from both sides than you divide by -2w
Getting the slope of all the tables (by getting the difference between succeeding y values and x values and getting the ratio of the difference in y and difference in x), I was able to determine that the third table (31, 18) and the fifth table (12, 7) have <span>lower unit rate than the rate represented in the equation y=3/5x (which has a slope of 0.6). To prove this:
third table calculation:
m (slope) = (y2-y1)/(x2-x1) = (36-18)/(62-31) = 0.58 (less than 0.6)
fifth table calculation:
</span>m (slope) = (y2-y1)/(x2-x1) = (14-7)/(24-12) = 0.58 (less than 0.6)
Answer:
Below in bold.
Step-by-step explanation:
If we draw a line from top right vertex perpendicular to the bottom line we get a right triangle.
Height of this triangle = sqrt(5^2 - 3^2) = 4.
This is also the height of the polygon.
The polygon is a trapezium so:
Area of the polygon = 1/2(5 + 8) * 4
= 6/5 * 4
= 26 m^2.
