Ahah its hard isnt it?....
Step-by-step explanation:
First, distribute the outside numbers into the parentheses:
5*x+5*-12+6=3*2x+3*-7
5x-60+6=6x-21
Combine like terms
5x-54=6x-21
Add 21 to both sides
5x-33=6x
Subtract 5x from both sides
you wind up getting x=-33
x=-33
you can check to make sure that's the correct answer but simply plugging in -33 for x and checking to make sure both sides of the equation are equal:
-33-12=-45*5=-225+6=-219
-33*2=-66-7=-73*3=-219
So, yes, x equals -33
Answer:
NORMDIST(RAND(),50,5)
Step-by-step explanation:
NORMDIST(RAND(),50,5) returns the random value from a normal distribution. The second space is meant for Mean and the third space is meant for standard deviation.
Answer:
C) -5/12
Step-by-step explanation:
To find the slope of a line with given points, you divide the difference of y-coordinates by the difference of the x-coordinates of those same 2 points.
x's:-9-3=-12
y's:-1-(-6)=5
Then, you put the answer of the y's in the numerator, and x's in the denominator, giving you 5/-12, but you can't have a negative in the denominator, moving it up to become -5/12 as the slope.
The linear function that maps the relation between kinetic energy and mass is given at the end of the question.
<h3>What is the kinetic energy of an object?</h3>
The kinetic energy of an object is given by the following formula:
E = 0.5mv².
In which:
- m is the mass of the object.
- v is the velocity of the object.
In this problem, we suppose a velocity of 2.5 m/s, hence the kinetic energy is:
E = 0.5m(2.5)² = 3.125m.
Hence the graph is plotted at the end of the answer.
