Answer:
2/4 or 1/2
Step-by-step explanation:
2/4 or 1/2 is the greater fraction.
Square root.
5^2 = 25 so sqrt25 = 5
Answer:
The graph of y = 1/2f(x) is the graph y = x and y = -x for -4 ≤ y ≤ 0
Step-by-step explanation:
Here we note that when y = 0, x = 0
when y = -4, x = -2
The equation is therefore of the form y = m·x + c
m = slope
c = y intercept = 0
Hence the first line is y = 2·x
The second line on the right is the mirror of the first on the left with slope;
Hence the second line on the right is y = -2·x
Hence for y = 1/2 f(x) we have;
y = 1/2 × 2·x = x and y = 1/2 ×-2·x = -x
Graphing the functions, we have
Answer:
3x^2 - 9x + 8
Step-by-step explanation:
To simplify:
- Distribute the -1 into the second term.
- Collect and combine like-terms (terms with the same variables or powers)
The expression can be rewritten has (2x^2 - 5x + 3) -1(-x^2 + 4x - 5)
After distributing the -1, the equation becomes:
- (2x^2 - 5x + 3) + (x^2 - 4x + 5)
The like-terms are:
- 2x^2 and x^2
- -5x and -4x
- 3 and 5
Combine the like-terms:
- 2x^2 + x^2 = 3x^2
- -5x - 4x = -9x
- 3 + 5 = 8
Substitute the simplified like-terms into the expression, in descending order:
Answer:
Step-by-step explanation:
-3.1+7-7.4x=1.5x-6(x-1.5)
We move all terms to the left:
-3.1+7-7.4x-(1.5x-6(x-1.5))=0
We add all the numbers together, and all the variables
-7.4x-(1.5x-6(x-1.5))+3.9=0
We calculate terms in parentheses: -(1.5x-6(x-1.5)), so:
1.5x-6(x-1.5)
We multiply parentheses
1.5x-6x+9
We add all the numbers together, and all the variables
-4.5x+9
Back to the equation:
-(-4.5x+9)
We get rid of parentheses
-7.4x+4.5x-9+3.9=0
We add all the numbers together, and all the variables
-2.9x-5.1=0
We move all terms containing x to the left, all other terms to the right
-2.9x=5.1
x=5.1/-2.9
x=-1+1/1.31818181818
