Answer:

Step-by-step explanation:

Given the expression

$\frac{(2^3)(2)^4}{2^{10}} \\$

Using the following laws of indices;

$\frac{a^m}{a^n} = a^{m-n}\\a^m \times a^n = a^{m+n}$

The expression becomes;

Step 1: Multiplication rule

$=\frac{(2^3)(2)^4}{2^{10}} \\= \frac{2^{3+4}}{2^{10}}\\= \frac{2^7}{2^{10}}$

Using the division rule of exponent (Quotient of powers);

$= \frac{2^7}{2^{10}} \\= 2^{7-10}\\= 2^{-3}\\also \ a^{-m} = \frac{1}{a^m}\\ 2^{-3}= \frac{1}{2^3}\\\frac{1}{2^3} = \frac{1}{8}$

Hence the result of the expression is 1/8

Find the solution to the system of equations.

N76 [4]

Answer:

x = -2, y = 5.

Step-by-step explanation:

y=−4x−3

y=−2x+1

Because y is common to both left sides:

-4x - 3 = -2x + 1

-4x + 2x = 1 + 3

-2x = 4

x = 4/-2

x = -2.

So y = -4(-2) - 3

= 8 - 3

= 5 .

Which of the following inequalities matches the graph? graph of an inequality with a dashed line through the points (0, 7) and (

stiks02 [169]

Answer:

2x + y < 7

Step-by-step explanation:

First we find the slope of the line that passes through the given points. The formula for slope is:

$m=\frac{y_2-y_1}{x_2-x_1}$

Using our points, we have

$m=\frac{7-5}{0-1}=\frac{2}{-1}=-2$

The y-intercept will be the point where the data crosses the y-axis. All y-intercepts have an x-coordinate of 0; since we already have the point (0, 7), we have the y-intercept at 7. This makes our equation

y = -2x + 7

The inequalities we're given are written in standard form, Ax+By=C. This means we need x and y on the same side of the equals in our equation.

Since the inequality is graphed below the line, we want our inequality to be

y < -2x+7

To move the x-value to the other side of the equation, we will add 2x to each side:

y+2x < -2x+7+2x

y+2x < 7

2x+y < 7
