Answer:

Step-by-step explanation:
We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point (8,1) and a slope from the equation y=-23x+5. We will chose point-slope since we have a point and slope.
Point slope:
in our new equation because it us perpendicular to it. This means we will need to change it into its negative reciprocal which is
.
We will substitute
and
.
.
This is the equation of the line perpendicular to y=-23x+5 that crosses through (8,1).
19.32=density D=m÷v so, v=m÷d
v=575÷19.32 v=about 29.8
20×7×2/7×5×11 = 280/385 = 8/11
Answer: b.2x
Step-by-step explanation:
why? because 2 can be divided into all of the numbers evenly!
all the numbers have (x)
it wouldn't be (2x^2) ,because one of the numbers have x^3
