Health matters because it determines the state your body is in. For example, if your body is not feeling well, you should not do certain things or the feelings and reactions can be worse for you. Your health is the most important thing in your life.
2x^2-15=x
2x^2-x-15=0
(X-3)(2x-5)=0
x-3=0 or 2x-5=0
X=3 2x=5
x=5/2=2.5
Answer:
Step-by-step explanation:
In system B, the first equation is the same, so clearly the <em>second</em> equation has been replaced. The only other equation in the system is the <em>first</em>, so that is the one that is multiplied by some number.
The number it is multiplied by must make the y coefficient be the opposite of the y-coefficient in the second equation, so they cancel when added. That is, the multiplier times -1 must be -4, so the multiplier must be <em>4</em>.
The purpose of doing this is to ensure the solution of System B <em>is exactly</em> the same as that of System A.
Answer:
Step-by-step explanation:
<u>Equation of the line</u>
The equation of the line in slope-intercept form is:
Being m the slope and b the y-intercept.
We are given two points for the required line: The x-intercept is -2, thus the point is (-2,0), and the y-intercept b=6 represents the point (0,6).
Since the value of b is 6, we use the first point to find the slope:
Solving:
m=3
The correct equation of the line is:
Keys on a keyboard because it can’t be letters because there are numbers and punctuation marks, it can’t be numbers because there are letters and punctuation marks, it can’t be punctuation merks either cause there are letters and numbers. So the only option left is keys on a keyboard cause it has all letters numbers and punctuation marks
