Answer:
the second choice
Step-by-step explanation:
All of our equations are in slope-intercept form. Slope-intercept form is y=mx+b. m stands for the slope, and b stands for the y-intercept. Our y-intercept is 3. Therefore, we can eliminate the equations that say the y-intercept isn’t b. Next, we can find the slope. We have the points (0, 3) and (3, 2). The formula for slope is y2-y1/x2-x1. 2-3 is -1, 3-0 is 3. Our slope is -1/3. After eliminating those without the y-intercept, we have A or D. We know that the slope is -1/3, so the answer must be D.
6x -3 + 4x = 5 + 3x + 4
10 -3 = 3x + 9
answer is C.
Solution:
Area of parallelogram
= b × h
= 20 × 16
= 320 in^2
Area of triangle
= 1/2 × 20 × 8
= 80 in^2
Area of figure
= 320 + 80
= 400 in^2
