Step-by-step explanation:
A equation of a line can be represented by

Where m is the slope and b is the y intercept.
For Line A, the slope is 0 so our m is 0 and our y intercept is 4 so our equation will be


For the second equation, qe have no y intercept and a undefined slope so that means that our equation will be in the form of

where a is the x intercept
7 is the x intercept so our equation is

To write the expression in radical form, the numerator of the fraction would become the power you raise it by and the denominator becomes the root.

Becomes:
![\sqrt[2]{(10n)^{3} }](https://tex.z-dn.net/?f=%20%5Csqrt%5B2%5D%7B%2810n%29%5E%7B3%7D%20%7D%20)
or just


Becomes:
![\sqrt[5]{(a) ^{6} }](https://tex.z-dn.net/?f=%20%5Csqrt%5B5%5D%7B%28a%29%20%5E%7B6%7D%20%7D%20)
I hope this helped! ( if so give brainliest please!! )
The expression (5³)⁹÷5¹² is simplified to 5^15
<h3>What are index forms?</h3>
Index forms are defined as the exponent or power of a number or variables.
It is also seen as a mathematical method of writing numbers that are too large or too small in simpler forms.
The laws of exponents are;
- Add the powers when they are being multiplied the bases are the same
- Subtract the exponents when they are divided and have the same base.
- Multiply the exponents when the bases are the same
Given the expression;
(5³)⁹÷5¹²
This is represented as;
(5³)⁹/5¹²
expand the bracket
5^27/5^12
Take the inverse exponent of the denominator
5^27-12
5^15
Thus, the simplified form is 5^15

Answer:
5x+17
Step-by-step explanation:
2(x+7)+3(x+1)
=2x+14+3x+3 you remove the bracket
=2x+3x+14+3 you collect like terms
=5x+17
