Answer: − x 2 + 5 x + 12 = 0 - x 2 + 5 x + 12 = 0
Step-by-step explanation:
Answer:
Step-by-step explanation:
The scale factor = 1 : 20
<u>The area is the product of two dimensions, so the area of the model part to actual part is:</u>
<u>If the actual plane has wing area of 400 ft², then the model will have wing area:</u>
Given:
Triangle Point coordinates or vertices:
A(16,0)
B(9,2)
C(2,0)
Required:
Side with slope -2/7
Solution:
To know which side has the slope required, we need to calculate the slope of each paired point by the two-point slope formula:
m = (y2-y1)/(x2-x1)
We first try points A and B.
m1 = (2-0)/(9-16)
m1 = -2/7
Thus, the side with the slope -2/7 is side AB.
Answer:
y= -3x-40
Step-by-step explanation:
first distribute
y+10= -3x-30
than subtract 10
y= -3x-40
I round the answer to the second digit and get 18.33
