Which value is equivalent to 7 x 5 x 2 divided by 7 x 3 to the 2nd power x 5 to the 0 power divided by 2 to the negative 3rd pow
FinnZ [79.3K]

Answer:

This is hard to read, but i guess that the equation is:

7*5*2/7*3^2*5^0/2^{-3}*2^{-9}

So we have some things to solve:

First, for any number:

x^0 = 1

then 5^0 = 1.

And for negative powers,

x^-n = (1/x)^n.

And we

Then we can rewrite our equation as:

\frac{7*5*2*3^2*1*2^3}{7*2^9}

now we can cancel the seven in the numerator and the denominator

\frac{5*2*3*2^3}{2^9}

now, remember the relation:

a^x*a^y = a^(x+y)

then:

2*2^3 = 2^4

and 2^4/2^9 = 2^-5 = (1^2)^5

Then our equation is:

\frac{5*3}{2^5}

15/2^5 = 0.46875

Answer:

Option D y\leq -3x-3 and y

Step-by-step explanation:

step 1

<u>Find the equation of the inequality A</u>

we know that

The solution of the inequality A (dashed line)  is the shaded area below the dashed line

The equation of the dashed line is y=-\frac{1}{2}x+2

therefore

The equation of the inequality A is y

step 2

<u>Find the equation of the inequality B</u>

we know that

The solution of the inequality B (solid line)  is the shaded area below the solid line

The equation of the solid line is y=-3x-3

therefore

The equation of the inequality B is y\leq -3x-3

The system of linear inequalities is

y\leq -3x-3 and y

Solve the system of equations by graphing: -1/3x + y=-1, y=4+1/3x
Arada [10]

-\frac{1}{3}x + y = -1   ⇒   y = \frac{1}{3}x - 1

To graph this line, plot a point at the y-intercept (0, -1), than plot the next point using the rise over run from the slope (\frac{1}{3}) by counting up 1 and to the right 3 of the y-intercept.  This gives you a second point of (3. 0).  Draw a line through those two coordinates.

Answer: Plot (0, -1) and (3, 0) and draw a line through them.

***************************************************************************************

y = 4 +  \frac{1}{3}x    ⇒   y =  \frac{1}{3}x  + 4

Same as above.  Plot the y-intercept (0, 4) and then use rise over run from the slope to plot (3, 5).

Answer: Plot (0, 4) and (3, 5) and draw a line through them.

***********************************************************************************

You should end up with two PARALLEL lines.  Since the lines never intersect, there are no solutions to this system of equations.

Answer: No Solution
