The answer is D because all sides are equal and it’s a equilateral triangle
When you multiply the first equation by 3, you get:
3 × 3x = 9x
3 × y = 3y (but when added, that part gets eliminated)
3 × 3 = 9
So you end up with
9x + 3y = 9
x - 3y = -2
(add)
10x = 7
So your answer is B. 10x = 7. I hope this helps!
Answer:
The slope of the line is m=-0.8 and y-intercept = 5.6.
Step-by-step explanation:
Given : Line of best fit : ![y = -0.8x+5.6](https://tex.z-dn.net/?f=y%20%3D%20-0.8x%2B5.6)
To find : Write a scenario that could work for the following line of best fit and explain the slope and intercept in this context?
Solution :
Line of best fit : ![y = -0.8x+5.6](https://tex.z-dn.net/?f=y%20%3D%20-0.8x%2B5.6)
Scenario - Let a person has 5.6 dollars and he spend 0.8 dollars every weekend.
So, The slope is 0.8 but also negative as there is decrements.
The y-intercept is 5.6, the value we obtain from the equation when we set x=0.
So, The slope of the line is m=-0.8 and y-intercept = 5.6.
Answer:
Since garden is rectangular in shape,
The area of grass needed to be painted =
Length x breadth.
Length = 21 ft
Breadth= 12ft
Area= (21 x 12)ft square
234ft square
