If m= 3 and n= 2, then m2-n2 is equal to

Mathematics

Ulleksa [173]3 years ago

Answer:

5

Step-by-step explanation:

(I'm assuming that by m2 and n2 you mean m to the power of 2 and n to the power of 2)

Whenever you have a number to a power, it is the same as that number times itself that power number of times. For example, 3 to the power of 4 is equal to 3 times itself 4 times, which is 3 * 3 * 3 * 3. If we use this and substitute the values in for m and n, we get that 3^2 - 2^2, and since 3^2 is 3 * 3 and 2^2 is 2 * 2 and 3 times 3 is 9 and 2 times 2 is 4, we get that 9 - 4 is 5.

<em>Note: This symbol means to the power of ----> ^</em>

-1/2 + 2/3= <br> Give simplified answer
babunello [35]
You need a common denominator of 6 because it's the least common denominator of 2 and 3. So you can change -1/2 to -3/6. And change 2/3 to 4/6. The new equation would be -3/6 + 4/6 = 1/6.

Answer:

y = 1x-5

Step-by-step explanation:

We know two points so we can find the slope

(0,-5) and (5,0)

m = ( y2-y1)/(x2-x1)

   = ( 0 - -5)/(5-0)

   (0+5)/(5-0)

    5/5

=1

We know the y intercept = -5

The slope intercept form is y = mx+b where m is the slope and b is the y intercept

y = 1x-5
