After solving $4^{3x-2}=4^{x+1}$ we get value of x: $x=\frac{3}{2}$

Step-by-step explanation:

We need to solve the equation $4^{3x-2}=4^{x+1}$ and find value of x:

Solving:

$4^{3x-2}=4^{x+1}$

Using the rule: if $if\,\,a^{x}=a^{y}\,\,then\,\,x=y$

Since our base is equal i.e 4 so,

$3x-2=x+1\\3x-x=1+2\\2x=3\\x=\frac{3}{2}$

So, After solving $4^{3x-2}=4^{x+1}$ we get value of x: $x=\frac{3}{2}$

Triangle PQR is reflected across a line, P = (4,–5), and P’ = (–4, –5). What is the line of reflection? the x-axis the y-axis th

Evgesh-ka [11]

For this case we have that the original vertex is given by:

P = (4, -5)

We apply the following transformation:

(x, y) (-x, y)

We have then:

(4, -5) (- (4), -5) (- 4, -5)

Therefore, we have a reflection on the y axis.

The point obtained is the vertice:

P '= (-4, -5)

Answer:

the line of reflection is:

the y-axis

Gregory’s age is 5 years greater than of Amanda’s age. Gregory is 17 years old. If Amanda’s age is denoted by x, which equation

Mariana [72]

Let Amanda's age = x.
Gregory's age = x + 5.

Since Gregory is 17 years old.
17 = x + 5
x = 17 - 5
x = 12

Amanda is 12 years old.

Which mathematical statement matches the vector operation shown in the geometric representation?

Sunny_sXe [5.5K]

Answer:

First Option $v+w = u$

Step-by-step explanation:

To graphically add two vectors a and b using the -tail and tip-method, you must draw the tail of b at the tip of the vector a. Then you must draw a line that goes from the tail of a to the tip of b. This line represents the sum of $a + b$ .

In this problem, notice that the tail of the vector w is on the tip of the vector v. The line that joins the tail of v with the tip of w is u.

Therefore we can say that $v + w = u$ .

The answer is the first option
