You don't really know where the x is. The way you have written it, technically its like this. (-3^2)*x and none of the answers agree with that.

It must be -3^(2x) + 5 In that case 0,4 works. That gives (-3)^0 = -1
-1 + 5 = 4
Unfortunately so does 1,-4 because -3^2 = - 9
- 9 + 5 = - 4

If (-2,76) is the answer, then the question should be written (-3)^(2x) - 5

Until the ambiguity is gone, we're not sure.

Find the value of x and y

Serhud [2]

1) 180° - 146° = 34
9х - 2 = 34
9х = 34 + 2
9х = 36
х = 36 : 9
х = 4
-------------

2) (9х - 2) + (6у + 44) = 180°
(9 * 4 - 2) + (6у + 44) = 180
(36 - 2) + (6у + 44) = 180
34 + 6у + 44 = 180
6у = 180 - 34 - 44
6у = 102
у = 102 : 6
у = 17

Explain how you can use proportional reasoning to determine the whole if you know that 21 is 60% of the whole.

mel-nik [20]

Step-by-step explanation:

$\frac{60}{100} \times x = 21 \\ x = \frac{21}{ \frac{60}{100} } = 35 \\$

Using prime factorization what is the GCF 3y 2 squared, 24y 3 cubed

WINSTONCH [101]

Answer:

$3y^2$

Step-by-step explanation:

Given:

To find the GCF of $3y^2\ and\ 24y^3$ using prime factorization.

Writing each in prime factors:

3 = 1 $\times$ 3

24 = 1 $\times$ 2 $\times$ 2 $\times$ 2 $\times$ 3

Now, GCF of 3 and 24 is 3

$y^2=1\times y\times y$

$y^3=1\times y\times y\times y$

GCF of $y^2$ and $y^3$ is $y\times y=y^2$ .

Therefore, the overall GCF of the two terms is $3y^2$

Answer:

Option A.

Step-by-step explanation:

Definition of Boyle's law: a law stating that the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature. There is thus a relationship between volume and pressure of the gas thus option B and C are incorrect.
