Answer:
x=-24
Step-by-step explanation:
Multiply both sides by 4 to get x=-24
The Answer Is -2.
Because You Would Have To Rearrange Your Equation By Subtracting What Is To The Right Of The Equal Sign From Both Sides Of The Equation.
Answer:
Explanation:
15 goes into 60, 4 times (1 fourth is equal to 25%).
15 goes into 75, 5 times (1 fifth is equal to 20%)
So 75 is one fifth more because it has a value of 15 more, and 60 is 1 fourth less than 75 because its value is more minuscule and less is more.
If you don't understand this was quite the challenge to explain.
Y=2x and y = x² - 3. To find the intersections of these 2 functions we proceed as follows:
2x= x²-3 → x² - 2x -3 =0
The zeros of this trinomial are x = 3 and x =-1
Now to find y-coordinates replace in any of the initial equation x by both values:
y = 2x . For x = 3 , y = 6
and for a = -1, y = -2
