Answer:

nice question...

so here we go

3^ -x = 1 / 3^x

so 1/ 3^x = 2 so 3^x = 1/2

we can write 3^2x as 3^x multiplied by 3^x right?..(law of exponents)

recall that 3^x =1/2

so now according to question we have to find the value of 3^2x =  1/2 * 1/2 = 1/4

Step-by-step explanation:

The given expression is an application of an exponential equation. The result shows that [tex]3^{2x} = \frac{1}{4}[/tex] if [tex]3^{-x}=2[/tex]

Given that [tex]3^{-x}=2[/tex]

This can also be expressed as [tex]\frac{1}{3^x} =2\\[/tex]

Cross multiply

[tex]\frac{1}{3^x} =2\\3^x = \frac{1}{2}[/tex]

Take the square root of both sides

[tex](3^x)^2 = (\frac{1}{2} )^2\\3^{2x} = \frac{1}{4}[/tex]

The result shows that [tex]3^{2x} = \frac{1}{4}[/tex] if [tex]3^{-x}=2[/tex]

Answer:

Brand A is the better buy

Step-by-step explanation:

bag Which is the better buy?

Step one

Brand A: $5 for 80 pounds of sand

Let us find the unit cost

Unit cost =5/80

=$0.0625 per pound

Brand B: $14 for 175 pound

The unit cost is

=14/175

=$0.08 per pound

Answer:

7/11

Step-by-step explanation:

I could tell it was either 7/11 or 9/13 because I knew 2/3 was .666 and the other one 5/12 is less than half, so it'd be less than .5.

7/11 = .6363

9/13= .6969

7/11 is the closest

Step-by-step explanation:

Step one

The shape of the cup is that of a cone

The volume of a cone

V=1/3πr²h

Radius= d/2 = 1.5in

Height =6in

Substitute

V=1/3*3.142*1.5²*6

V=42.42/3

V=14.13in³

Answer:

X= -14

Answer:

69 calories

Step-by-step explanation:

Given that :

Number of calories in 28 grams = 161

9 cashews = 12 grams

Number of calories consumed :

28 grams = 161 calories

12 grams = x

Cross multiply :

28x = 161 * 12

28x = 1932

x = 69 calories

Answer:

1 and 2 is a function.But the third one isn't.

explanation:

When there is more than one point on a vertical line that is not a function.Like in the third picture points (2,1) and (2,-1) are on the same vertical line.

P.S: it is a function if there is more than one point on a horizontal line.

Why you may ask:

x are the domain, y are the codomain. X can have multiple Y but Y can't have more than one X. To embody: think Xs as mothers and Ys as childrens , a mother can have more than one children but every children can have only one biological mother.

Answer:

This graph shifted UP by 3 units

Step-by-step explanation:

The parent function of the absolute value is:

f(x) = | x |

If f(x) is reflected across the y-axis, it would map to itself. If it was reflected across the x-axis, it would map to a negative-valued function for all x.

The graph shown is not a reflection, but it's a translation. Note the parent function passes through the origin, thus the graph is a translation of 3 units up.

This graph shifted UP by 3 units

Step-by-step explanation:

We assume that point X is the intersection point of the medians. Then ...

  MQ = 3XQ

  3x -3 = 3(2x -6)

  3x -3 = 6x -18 . . .  eliminate parentheses

  15 = 3x . . . . . . . . . add 18-3x

  5 = x . . . . . . . divide by 3

4x^2-3x+2

Step-by-step explanation:

Answer:

4x^2 - 3x + 2

Step-by-step explanation:

(3x^2 + 2x - 8) + (x^2 - 5x + 10)

(3x^2) + (x^2) = 4x^2

(2x) + (-5x) = -3x

(-8) + (10) = 2

4x^2 - 3x - 2

Given:

A linear function starting at point C at (3, –2) and ending at point D at (–2, 3).

To find:

The rate of change and the initial value.

Solution:

If a linear function passes through two points [tex](x_1,y_1)\text{ and }(x_2,y_2)[/tex], then the equation of linear function is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

The given linear function passes through (3,-2) and (-2,3). So, the equation is

[tex]y-(-2)=\dfrac{3-(-2)}{-2-3}(x-3)[/tex]

[tex]y+2=\dfrac{3+2}{-5}(x-3)[/tex]

[tex]y+2=\dfrac{5}{-5}(x-3)[/tex]

[tex]y+2=-(x-3)[/tex]

Subtracting 2 on both sides, we get

[tex]y=-x+3-2[/tex]

[tex]y=-x+1[/tex]

On comparing this equation with slope intercept form [tex]y=mx+b[/tex], where, m is slope and b is y-intercept, we get

[tex]m=-1[/tex] and [tex]b=1[/tex]

Therefore, the rate of change is -1 and the initial value is 1.
