C: SAS

Step by step:
The first side is the side that was already established is the same as the other (ab & bc) The angles from point b are congruent because it’s an isosceles triangle so the mid point of the base is the altitude of the triangle and angle bisector of the angle opposite of it. Since it’s an angle bisector both are equal. The third side is the one that they share (bd). Then using SAS you can prove congruency.
Hope that helps :)

Which table represents the same linear relationship as y = 3x - 2?

Trava [24]

Answer:

Table 4 represents the same linear expression as y = 3 x - 2.

Step-by-step explanation:

Here, the given expression is y = 3 x -2

So now check the any random pair of each table by putting in the given equation.

TABLE 1 : (2,-5)

y = 3x -2 ⇒ -5 = 3(2) -2

or, -5 = -4 , NOT POSSIBLE

TABLE 2 : (0,3)

y = 3x -2 ⇒ 3 = 3(0) -2

or, 3 = -2 , NOT POSSIBLE

TABLE 3 : (1,2)

y = 3x -2 ⇒ 2 = 3(1) -2

or, 2 = 1 , NOT POSSIBLE

TABLE 4 : (1,1)

y = 3x -2 ⇒ 1 = 3(1) -2

or, 1 = 1 , POSSIBLE

checking for (2,4)

4 = 3(2) - 2 ⇒4 = 4 POSSIBLE

Here, table 4 satisfies the given points in the expression y = 3x -2

Hence, it represents the same linear expression .

Is f(x)=3x5^2x-3 an exponential function? If so, write it in the form f(x)=ab^x

Anna11 [10]

Answer:

$f(x)=\frac{3}{125} * 25^x$

Step-by-step explanation:

Given

$f(x)=3*5^{2x-3}$

Required

To determine if it is an exponential function, we have to write in form of

$f(x) = ab^x$

If we're able to do so, then the function is an exponential function.

If otherwise, then it is not

$f(x)=3*5^{2x-3}$

Apply Law of indices

$f(x)=3*\frac{5^{2x}}{5^3}$

Express 5^3 as 125

$f(x)=3*\frac{5^{2x}}{125}$

Factorize the exponent of 5

$f(x)=3*\frac{5^{(2)x}}{125}$

Express 5^2 as 25

$f(x)=3*\frac{25^x}{125}$

This can be rewritten as:

$f(x)=\frac{3}{125} * 25^x$

By comparing the above to $f(x) = ab^x$

We have that

$a = \frac{3}{125}$

$b^x = 25^x$

Since, we've be able to express the function as $f(x) = ab^x$

Then, $f(x)=3*5^{2x-3}$ is an exponential function

According to the Rational Root Theorem, what are all the potential rational roots of f(x) = 9x4 – 2x2 – 3x + 4?

Tanzania [10]

The coefficients of x4 is 9. It has factors of 1, 3, and 9. The constant is 4. It has factors of 1, 2, and 4.
The (positive and negative) ratios of the factors of the coefficient of the x4 and the constant 4 are the potential rational roots of the function.
The answers are:
1, -1, 3, -3, 9, -9, 1/2, -1/2, 3/2, -3/2, 3/4, -3/4, 9/2, -9/2, 9/4, -9/4
