Answer:
5/3
Step-by-step explanation:
We can find the slope of a line given two point by using
m = (y2-y1)/(x2-x1)
= (10-5)/(4-1)
=5/3
Answer:
m > -5
Step-by-step explanation:
Divide your inequality by the coefficient of m, which is -3. Doing that requires you reverse the comparison symbol:
(-3m)/(-3) > (15)/(-3)
m > -5
_____
The comparison symbol is reversed whenever an inequality is multiplie or divided by a negative number. You might be able to see why when you look at the relation between a couple of integers:
-2 < -1
2 > 1 . . . . . . multiply the above by -1
Multiplying by a negative number effectively reflects the comparison across the center of the number line. As we know from looking in a mirror; reflection reverses left and right, so numbers that were farther to the right (more positive) are now farther to the left (more negative).
Answer:
x+5y =30
this is random because it wont let me submit the answer unless I write 20 characters lol
As the exponent is negative, we can rewrite the expression as (125/64) raised to the power 2/3.
So, (125/64) raised to the power 2/3 can also be written as [(5/4) raised to the power 3] raised to the power 2/3. The exponents will multiply and the final exponent will be 2.
Hence the answer will be (5/4) squared.
Therefore the answer is (24/16).
