The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .
I am unable to read all of the options in the picture you provided but I hope this helps! (:
Answer:
if ur trying finding the y-intercept it's -24
Step-by-step explanation:
slope- intercept form is y=mx+b we know m is 4 (7,4) 7 is the x 4 is the y ...
then you plug them in and we know 4 times 7 is 28 and then 4-s8 is -24
Answer:
see below
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
We can find the radius from the diameter
r = d/2 = 34/2 = 17
V = (3.14) (17)^2 * 27
V =24501.42 m^3
The surface of a cone is found by
SA = pi r^2 + pi r l where l is the slant height
We can find the radius from the diameter
r = 8/2 = 4
SA =(3.14) * 4^2 + 3.14 * 4*7
=50.24+87.92
138.16 in^2
The lateral surface area of a pyramid is found by taking the area of the sides
LSA = 4 * the area of a triangle
we multiply by 4 since there are 4 sides
= 4 * 1/2 b*h where b is the base of the triangle and h is the height of the triangle. (in this case it would be the slant height)
= 2 * 8 *22
=352 m^2
(7-11) • (5) = -20
A. (5) • 7 + (5) • (-11)
↳ 35 + (-55)
↳ 35 - 55 = -20
B. -(-7+11) • (5)
↳ -4 • 5 = -20
C. (5) • 7 - (5) • 11
↳ 35 - 55 = -20
D. (7+11) • (5)
↳ 18 • 5 = 90
A B & C are correct
