Answer:

a) 12x + 22   b) 17x^{2} - x

Step-by-step explanation:

Perimeter is the sum of the each side length.

The first example is a rectangle so the (4x+8) and the (2x+3) are doubled.

(4x+8) x 2 = 8x+16

(2x+3) x 2 = 4x + 6

12x+22

(6x^{2} - 12x) + (2x^{2} + x) + (9x^{2} + 10x)

combine like-terms.

17x^{2} - x

Answer:

12x + 22 for the rectangle, 17x^2 - x for the triangle

Step-by-step explanation:

The perimeter of a square/rectangle is equal to 2*width + 2*length

So for the rectangle, it would be 2*(4x + 8) + 2*(2x + 3)

This can be further simplified as 8x + 16 + 4x + 6

Which can be further simplified as 12x + 22

The perimeter of a triangle is equal to length if side one + length of side two + length of base

That would be (6x^2 - 12x) + (2x^2 + x) + (9x^2 + 10x)

Which becomes 8x^2 - 11x + (9x^2 + 10x)

17x^2 - x

Solve the inequality for x -5x - 49 > 113
Anika [276]
X < -40.5

To find this, here are the steps:

Combine like terms like so:

-4x - 49 > 113

Then, begin to isolate the variable x by adding 49 to both sides leaving you with:

-4x > 162

Then divide by negative four. Don’t forget, dividing by negatives switches the way the sign points so your final product will be:

x < -40.5

Hope this helps!

Write an equation for each vertical translation of y=f(x) .<br> 2 units up.
Damm [24]

The equation for the vertical translation of y=f(x). 2 units up is y=f(x)+2.

Using equations of the form y=f(x), you may be able to modify the graph in various ways. For example, you can move the chart up, down, left, or right, flip it around the x or y-axis, or stretch or shrink it vertically or horizontally. Understanding these transformations makes it easy to graph different functions. Start with a "basic model" and apply a series of transformations/modifications to change it to the desired function.

A point on the graph of y=f(x) has the shape (x,f(x)).

The points on the graph of y=f(x)+2 are of the form (x,f(x)+2).

So, the graph for y=f(x) +2 is the same as the graph for y=f(x) shifted up by 2 units.

The new equation is:

y=f(x)+2

More problems related to the translation of shapes are given below.

What is the value of y in the solution to the system of equations?
LUCKY_DIMON [66]

To solve for y you have to simplify both sides of the equation, then isolating the variable which equals to...

y = -4x/3 + 4

Next, you have to move all terms that don't contain y to the right side and solve.

y = 10 + 2x/3

____

Now we solve the first variable in one of the equations, then substitute the result into the other equation.

Point Form: (-3,8)

Equation Form: x = -3, y = 8

____

Leaving it to be the only choice which is 'D.) 8', I hope this helps, as always. I wish you the best of luck and I hope you have a nice day..
