Answer:
1.5^2 = 2.25
(it looks like 1.5 but if it's 15 then it would be 225)
Step-by-step explanation:
1.5^2 means (1.5*1.5) you multiply the number by itself by how many it says to do. So if it were 1.5^52 you would multiply 1.5 by 1.5, 52 times.
The first one should be read as between 75 and 97 inclusive. That means you are using ≤
75 ≤ x ≤ 97 As a compound inequality this is
75 ≤ x ; x ≤ 97
The second one is just a bit harder. That's because a place in Ohio probably could go down to - 36. Again, both ends of the inequality use ≤
-36 ≤ x ≤ 20 As a compound inequality
-36 ≤ x; x ≤ 20
I'm not sure if you should be including units like 20°F. If you are, add them in.
After canceling out the x^2 and all the other fun stuff, you should get (x+4)/(x-1)
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
