It's answer is D. Because from what I see it isn't the other answers.
Slope = (11 + 5)/(4 - 2) = 16/2 = 8
y = mx + b
b = y - mx
b = 11 - (8)(4)
b = 11 - 32
b = -21
Equation: y = 8x - 21
Answer : y = 8x - 21
The answer is A because of the bar graph
Answer:
#4=10.5
#5=48
Step-by-step explanation:
The formula for the triangle for area is 1/2 time base times hight
The forumale fot the triangle for volume is 1/2 time base times hight
So for number #4 it will be 1/2 x 3 x 7
and number #5, it will be 1/2 x 8 x 12
All you need to do is to break the value into prime factors! Here is how you should work out such problem...
840
= 4 * 210
= 2² * 21 * 10
= 2² * 7 * 3 * 5 * 2
= 2³ * 3 * 5 * 7
