If you have a ratio like 1 yard for 3 feet you can graph that to get a better understanding of size
Answer:
y - 5 = -4(x + 3)
Step-by-step explanation:
This question is asking you to use and make an equation using the base of the "point-slope form." This is a common equation used when dealing with coordinates and graphs in math. The point-slope form equation looks like this:
y - y₁ = m(x - x₁).
We are going to need to use this equation base to create our problem from the information given. If you are wondering what those subscripts of 1 mean (the 1 in y₁ and x₁), I will explain. Remember that:
slope (m) = <u>y - y₁</u>
x - x₁
So, our first y value (which is the y-coordinate of 5 in [-3, 5]) can be added into the problem base that I had mentioned above:
y - <u>5</u> = m(x - x₁).
Now, we need to place the first x value (which is the -3 in [-3, 5]) can be added into the base problem once more:
y - 5 = m(x - (<u>-3</u>)).
Because a negative number with a negative symbol in front of it creates a positive, we can change that as well:
y - 5 = m(x + 3).
Fortunately, the question provides a slope ready for use. The question says that the slope is -4, so we can place this into the equation now:
y - 5 = -4(x + 3).
I hope that this helps.
Answer:
C
Step-by-step explanation:
Answer:
The area of shaded sector
Formula A = (θ / 360°) × πr²
θ=360°-140°=220°
r=18yd
We have A=(220/360)×3.14×(18)²
=621.72yd²
Area of sector is621.72yd².
Standard form: Ax + By = C
so
<span>y +7= -2/5(x-10)
5y + 35 = -2x + 20
2x + 5y = -15 .............this is </span>Standard form <span>
