I need help ASAP please! <br>The graph of y=f(x) is shown below.<br><br>Graph y=1/2f(x)
WARRIOR [948]

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

Slope, \ m = \frac{y_2- y_1}{x_2- x_1}} = \frac{0 - (-4)}{0 - (-2)} =\frac{4}{2} =2

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;

Slope, \ m = \frac{y_2- y_1}{x_2- x_1}} = \frac{-4 -0}{2-0} =\frac{-4}{2} =-2

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

Simplify <br><br> (2x^{2} - 5x + 3) - (-x^{2} + 4x - 5)
MrRissso [65]

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:

  • 3x^2 - 9x + 8

Please help! And show or explain your work! <br> (I WILL MARK BRAINLIEST)
netineya [11]

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
