Answer: DEFG is a parallelogram
Explanation:
Hi there!
To solve this problem, we need to divide the total amount of tables by the amount of students:
40 / 10 = 4
So, we need 4 tables to seat 40 students.
Hope this helps!
Answer:
y = 2x + 4
Step-by-step explanation:
Two points on this line are (-2, 0) and (0, 4). Going from the first to the second, x increases by 2 (this is the 'run') and y increases by 4 ('rise').
Thus, the slope of this line is m = rise / run = 4/2 = 2
Using the slope-intercept formula, we get y = mx + b = 2x + b
Let x = -2 and y = 0 to find b: 0 = 2(-2) + b, so b = 4, and the desired equation is then:
y = 2x + 4
20 - 2(5 + 5)
20 - 2(10)
20 - 20
