Answer:
D) y = −2/5x
Step-by-step explanation:
In the equation for a line ...
y = mx +b
the constant 'b' is the y-intercept of the line. The y-intercept is the value of y when x = 0.
The point (0, 0) tells you the y-intercept is 0, or b=0. That reduces the equation to the form ...
y = mx
The value of m is most easily found if you have a point where x=1. In that case, ...
y = 1m
y = m
In the given list of points, there is one that is helpful here: (1, -0.4). That is, the equation for the given points is ...
y = -0.4x
The answer choices are given as fractions, so you must convert -0.4 to the fraction -2/5.
y = -2/5x . . . . describes the given points
-6(5x-3) -36x+6
-30x+18<-36x+6
-30x+36x<6-18
6x<6-18
6x<-12
x<-2

Answer:
25 1/2 feet
Step-by-step explanation:
Answer:
a radius 5mmm diameter 10mm
b radius 6cm diameter 12cm
c radius 9m diameter 18m
d radius 8km diameter 16km
e radius 11m diameter 22
f radius 15mm diameter 30mm
g radius 13km diameter 26km
h radius 7 diameter 14
Step-by-step explanation:
When looking for radius you divide your diameter by two
When looking for diameter you multiply your radius by 2
First you are using the pothagorean theorem which is a^2+b^2=c^2. You have a and b, so you should plug them in to get 4^2+4^2=c^2. Then simplify it some more to 16+16=c^2. Now finish simplifying to c^2=32. Now take the square root of each side and you have your answer. So your answer will be c=√32 or c is about 5.66.
