A is 64

when simplifying expressions and they are the same base is you
1. multiple - add the exponents keep the base

2. divide - subtract the exponents keep the base

so when you have 2^3• 2^3 you will add the exponents which gives you 2^6 and then you simplify that down to your single integer

b is 36

6^7/6^5 = 6^2 which simplifies down to 36

i hope this kind of helps that is how i learned it

Answer:

a is 64 b 125 c 36

Step-by-step

so you do 2 times 2 times 2 = 8 because there is a 3 so you multiply it by it self how ever many times the number above it says so after you do that its the same for the other number so they are both 8 so 8 times 8 is 64

Solve each equation by completing the square. If necessary, round to the nearest hundredth.

siniylev [52]

$x^2-18x=19\\\\x^2-2x\cdot9+9^2-9^2=19\\\\(x-9)^2-81=19\\\\(x-9)^2=19+81\\\\(x-9)^2=100\iff x-9=\pm\sqrt{100}\\\\x-9=-10\ \vee\ x-9=10\\\\x=-10+9\ \vee\ x=10+9\\\\x=-1\ \vee\ x=19$

$4a^2+8a-20=0\ \ \ \ /:4\\\\a^2+2a-5=0\\\\a^2+2a\cdot1+1^2-1^2=5\\\\(a+1)^2-1=5\\\\(a+1)^2=5+1\\\\(a+1)^2=6\iff a+1=\pm\sqrt6\\\\a=-\sqrt6-1\ \vee\ a=\sqrt6-1\\\\a\approx-3.45\ \vee\ a=\approx1.45$

Consider the following system of equations.

Dmitrij [34]

Answer:

C. When the equations -10x + 5y = -60 and -3x − 5y = -5 are added together, a third linear equation, -13x = -65, is formed, and it shares a common solution with the original equations.

Step-by-step explanation:

2x-y=12

-3x-5y=-5

multiply the first equation by -5

-10x +5y = -60

add the 2 equations together

-3x-5y=-5

-10x +5y = -60

-------------------------

-13x = -65

We use the addition property of equality which says adding the same thing to both sides, doesn't change the equation, so we will get the same answer as the original equation

Given f(x) = 1/x+4 and <br> g(x) = 8/x-1, find the given domain of f(g(x)).

Artemon [7]

Answer:

he domain of the composition is all real x values except for x = -1

In other words: $\left \{ x \, |\, x \neq -1} \right \}$

Step-by-step explanation:

Let's find the composition $f(g(x))$ in order to answer about its domain (where on the Real number set the function is defined), give the two functions:

$f(x)= \frac{1}{x+4}$ and $g(x)=\frac{8}{x-1}$ :

$f(g(x))=\frac{1}{g(x)+4} \\f(g(x))=\frac{1}{\frac{8}{x-1} +4} \\f(g(x))=\frac{1}{\frac{8+4(x-1)}{x-1} }\\f(g(x))=\frac{x-1}{8+4x-4} \\f(g(x))=\frac{x-1}{4+4x} \\$

This rational function is defined for every real number except when the denominator adopts the value zero. Such happens when:

$4+4x=0\\4x=-4\\x=-1$

So the domain of the composition is all real x values except for x = -1

Find the equation of the line that passes through the points (4,

svetoff [14.1K]

Step-by-step explanation:

the slope = (1-11)/(-1-4) = -10/(-5) = 2

the equation is : y -11 = 2(x-4)

=> y -11 = 2x -20

y = 2x -8 +11

y = 2x +3

other forms :

<=> 2x - y = -3

<=> 2x - y + 3 = 0
