The triangle in the picture is an isoceles triangle meaning that angles P and R are congruent to one another. Here is how to solve the problem:

1. Set the equations equal to one another: 6x-15 = 4x + 5

2. Move the values to have "x" on one side: 2x - 15 = 5....2x=20

3. Divide by 2 to find "x": x=10

X = 10! Hope this helped :)

What is the first step in the solution of 3x2+6x=12 by completing the square?

aleksandrvk [35]

Answer:

B: r² + 2r = 4

Explanation:

$\rightarrow \sf 3x^2+6x=12$

<u>divide both sides by 3</u>

$\rightarrow \sf x^2+2x=4$ ← This is the result of the first step.

<u>factor out the common term</u>

$\rightarrow \sf x(x+2) = 4$

$\rightarrow \sf x = 4, \ x+2 = 4$

<u>simplify</u>

$\rightarrow \sf x = 4, \ x= 2$

Carlos wants to practice piano 2 hours each day. He practices piano for 3/4 hour before school and 7/10 hour when he gets home.

kiruha [24]

Answer

Find out the how many hours has Carlos practiced piano .

To prove

As given

$He\ practices\ piano\ for\ \frac{3}{4}\ hour\ before\ school.$

$\frac{7}{10}\ hour\ when\ he\ gets\ home.$

Than

$Total\ hours\ carlos\ practiced\ piano = \frac{3}{4} + \frac{7}{10}$

L.C.M of (4,10) = 20

$Total\ hours\ carlos\ practiced\ piano = \frac{3\times 5+7\times 2}{20}$

$Total\ hours\ carlos\ practiced\ piano = \frac{15+14}{20}$

$Total\ hours\ carlos\ practiced\ piano = \frac{29}{20}\ hours$

Therefore the total hours Carlos practiced piano is 1.45 hours .

Step-by-step explanation:

$3x+12x+12=7\\15x+12=7\\15x=-5\\x=\frac{1}{3}$

____

$3(\frac{1}{3} )+4y=7\\1+4y=7\\4y=6\\y=1.5$

$3(\frac{1}{3}) +4(1.5)=7$

PartA)What are the transformations are needed in in order to obtain the graph of G(x) from the graph of f(x) Select all that app

iVinArrow [24]

Part A)

Recall that:

1) The function represented by the graph of the function f(x) translated vertically n units up and horizontally m units left is:

$f(x+m)+n\text{.}$

2) The function represented by the graph of the function f(x) reflected over the x-axis is:

$-f(x)\text{.}$

Now, notice that g(x) is the function f(x) reflected over the x-axis and then translated vertically 6 units up and horizontally 4 units left.

Answer Part A:

Options B, C, and D.

Part B) To graph g(x) we will reflect the graph of f(x) over the x-axis and then we will translate it vertically 6 units up and horizontally 4 units left.

We know that the graph of f(x)=|x| is:

The above graph reflected over the x-axis is:

Finally, the above graph translated vertically 6 units up and horizontally 4 units left is:

Answer part B:
