Answer:

The length of AB is 19.

Step-by-step explanation:

Lengths BC and AD are congruent to each other.

BC: 17x + 4 equals AD:18x

17x + 4 = 18x .... that's the equation it makes and the equation we are going to solve.

$\ 17x + 4 = 18x \\ \frac{ - 17x \: \: \: \: \: \: \:\: = - 17x} {4 = 1x} \\ \\ \frac{4 }{1} = \frac{1x}{1} \\ 4 = x$

Since we found out the value for 'x', now we are going to plug it in 4x + 3.

$4x + 3 \\ 4(4) + 3 \\ 16 + 3 \\ 19$

The length of AB is 19.

What’s is the answer

When you are multiplying an exponent directly into a number/variable with an exponent, you multiply the exponents together.

For example:

$(x^{2} )^{3} = x^6$

$(x^{3} )^5=x^{15}$

When you are multiplying a variable with an exponent by another variable with an exponent, you add the exponents together.

For example:

$(x^{2} )(x^{3})=x^{5}$

$(x^{1} )(x^{2})=x^{3}$

$(\frac{(x^{-3})(y^{2})}{(x^{4})(y^{6})} )^{3}=\frac{(x^{-9})(y^{6})}{(x^{12})(y^{18})}$

You multiply 3 into each exponent in the numerator and the denominator

$\frac{(x^{-9})(y^{6})}{(x^{12})(y^{18})}= \frac{y^{6}}{(x^{9})(x^{12})(y^{18})}$

When you have a negative exponent, you move it to the other side of the fraction to make the exponent positive.

$\frac{y^{6}}{(x^{21})(y^{18})} = \frac{1}{(x^{21})(y^{12})}$

When you have something like this:

$\frac{x^{2}}{x^5}$

You subtract the exponents together, so:

$\frac{x^2}{x^5} = x^{2-5} = x^{-3} = \frac{1}{x^3}$

Your answer is the second option

Find the slope of a line perpendicular to y = 3x + 7

Vikki [24]

Answer:

-1/3

Step-by-step explanation:

The slope of the line has the form y = mx + b where m is the slope. Here the slope is m = 3. A line perpendicular to it will have a negative reciprocal slope. The negative reciprocal of 3 is -1/3.
