<h3>Answer: x = 7</h3>

Explanation:

Segment addition postulate

CD+DE = CE

this basically is the idea of gluing smaller pieces together to get a larger structure. We can go in reverse to break up a large item into smaller bits. This is assuming there is no leftovers, overlaps, or parts wasted/lost.

CD = 9

DE = 3x+6

CE = 36

----

CD+DE = CE

9+3x+6 = 36

3x+15 = 36

3x = 36-15

3x = 21

x = 21/3

x = 7

-----

If x = 7, then

DE = 3x+6 = 3*7+6 = 21+6 = 27

and

CD+DE = 9+27 = 36 = CE

4x2 + 8x - 7 - (3x2 - X+9)

Andreas93 [3]

Answer:

<h2> ${x}^{2} + 9x - 16$ </h2>

Step-by-step explanation:

$4 {x}^{2} + 8x - 7 - (3 {x}^{2} - x + 9)$

When there is a (-) in front of an expression in parentheses, change the sign of each term in the expression:

$4 {x}^{2} + 8x - 7 - 3 {x}^{2} + x - 9$

Collect like terms

$4 {x}^{2} - 3 {x}^{2} + 8x + x - 7 - 9$

${x}^{2} + 9x - 7 - 9$

Calculate

${x}^{2} + 9x - 16$

Hope this helps...

Good luck on your assignment...

Answer:

See below

Step-by-step explanation:

<h3>Part (a)</h3>

f(x - 1) is the translation of f(x) one unit right.

So the graph is exactly same shape but shifted right one unit.

<h3>Part (b)</h3>

f(x) has vertex (-1, 2)

<u>The function y = f(-x) + 2 will have the vertex changed as per rule:</u>

(x, y) → (-x, y + 2)

<u>So the new vertex is:</u>

(-1, 2) → (-(-1), 2 + 2) = (1, 4)

3) Find two consecutive even integers such that their sum is equal to the difference of 3 times the larger & 2 times the sma

swat32

Answer:

In assumption, x is the smaller even integer and x+2 is the next so it will be larger.

The integers are 4 and 6

Step-by-step explanation:

Let the two consecutive even integers be x and x+2

Here x is the smaller even integer and x+2 is the next so it will be larger.

Now according to the given statement

Sum of both: $x+x+2$

difference of 3 times the larger & 2 times the smaller: $3(x+2)-2x$

Putting the sum and difference equal:

$x+x+2 = 3(x+2)-2x$

Solving the equation

$2x+2 = 3x+6-2x\\2x+2 = x+6\\2x+2-x = x+6-x\\x+2 = 6\\x+2-2 = 6-2\\x = 4$

The next integer will be:

$x+2 = 4+2 = 6$

Hence,

In assumption, x is the smaller even integer and x+2 is the next so it will be larger.

The integers are 4 and 6.
