Answer:
-300
Step-by-step explanation:
-21 = 7x/100
-21=7x/2^2*5^2
x=-300
Step-by-step explanation:
When the slope of the function is positive, it is increasing
when the slope of the function is negative, it is decreasing
just like with the line function y = mx + b
so if you put a line tangent to the function at every point the slope of the line will indicate a increasing or decreasing point of the function
also beware where the slope is zero it is not increasing or decreasing
there are two intervals of increasing, one interval of decreasing and two point of zero slope or neither increasing or decreasing
increasing interval 1) x < -2 2) x > 1.5
decreasing interval 1) -2 < x < 1.5
at -2 and 1.5 the slope is zero
Answer:
X = {0, -1.166666667}
Step-by-step explanation:
Simplifying
8X(6X + 7) = 0
Reorder the terms:
8X(7 + 6X) = 0
(7 * 8X + 6X * 8X) = 0
(56X + 48X2) = 0
Solving
56X + 48X2 = 0
Solving for variable 'X'.
Factor out the Greatest Common Factor (GCF), '8X'.
8X(7 + 6X) = 0
Ignore the factor 8.
Subproblem 1
Set the factor 'X' equal to zero and attempt to solve:
Simplifying
X = 0
Solving
X = 0
Move all terms containing X to the left, all other terms to the right.
Simplifying
X = 0
Subproblem 2
Set the factor '(7 + 6X)' equal to zero and attempt to solve:
Simplifying
7 + 6X = 0
Solving
7 + 6X = 0
Move all terms containing X to the left, all other terms to the right.
Add '-7' to each side of the equation.
7 + -7 + 6X = 0 + -7
Combine like terms: 7 + -7 = 0
0 + 6X = 0 + -7
6X = 0 + -7
Combine like terms: 0 + -7 = -7
6X = -7
Divide each side by '6'.
X = -1.166666667
Simplifying
X = -1.166666667
Don't get mad if it is wrong I had to do the math fast.
Answer:
x = minus two
Step-by-step explanation:
5x+3 = 2x-3
5x-2x = -3-3
3x = -6
x = -6÷3
x = -2
