I'll help with a few because no-one wants to just do your homework
there is the formula way or the intuitive way
(-19, -2) (-17, -10)
now slope is (difference in y)/ (difference in x)
or
(y2 - y1)/(x2 - x1) the formula. where x2 just means the second x
<u>formula way:</u>
(-19, -2) (-17, -10)
(-10 - (-2))/ (-17 - (-19)) ReM: Negative on number and in the formula
(-10 + 2)/ (-17 +19) = -8/2 slope is - 8/2
<u>intuitive way</u>
(-19, -2) (-17, -10)
(difference in y)/ (difference in x)
lets looks at the ys
-2 and -10; how many steps from -2 to -10? -8 the diff in y
lets looks at the xs
-19 to -17; how many steps from -19 to -17? + 2 the diff in x
so its -8/2
Answer:
C.
Step-by-step explanation:
recall that the point-slope form of a linear equation is given by
y = mx + c
Rearranging so that it is in the same form as the answer choices, we get
y = c + mx
where m is the slope and c is the y-intercept
we note the following observations
1) The line goes from top left to bottom right, this means that the slope is negative, hence m has to be negative. (in our case, all the choices have negative x)
2) The line crosses the y-axis at y = 4, this means the y-intercept is 4 and hence c = 4.
If we look at the choices, only choice B satisfies both observations (that m is negative and c = 4)
Answer:
105.12 feets
Step-by-step explanation:
From the figure x we can identify a rectangle and a semicircle :
Area of rectangle = Length * width
Area = 8 * 10 = 80 feet²
The Area of a semicircle = 1/2πr²
Radius, r = 8 /2 = 4 feets
A = 1/2 * 3.14 * 4²
A = 3.14 * 8
A = 25.12 feet²
Area of figure = 80 + 25.12 = 105.12 feets
Multiply the amount of inches it is by 30 and you will know what the size is in feet.
