Answer:
(a)
(b)
(c)
Step-by-step explanation:
We are required to construct 3 linear equations starting with the given solution z = 1/3.
<u>Equation 1</u>
<u />
<u />
Multiply both sides by 9

Rewrite 3 as 5-2
9z=5-2
Add 2 to both sides
Our first equation is: 
<u>Equation 2</u>
<u />
<u />
Multiply both sides by 21

Rewrite 7 as 11-4
21z=11-4
Subtract 11 from both sides
Our second equation is: 
<u>Equation 3</u>
<u />
<u />
Multiply both sides by 6

Rewrite 6z as 4z+2z
4z+2z=2
Subtract 2z from both sides
Our third equation is: 
Answer:
ion
Step-by-step explanation:
The parabola opens towards left, this means the squared term is y with negative coefficient.
The vertex is given to be the point (-1,-3). So, the general equation of the parabola will be like:

where a is any constant.
In the given options, only 1 such equation is available and that is option C.
So the answer to this question is option C
Answer:
![\sqrt[4]{x^3}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7Bx%5E3%7D)
Step-by-step explanation:
First, let's examine our original statement.

Using exponent rules, we know that if we have
, then simplified, the answer will be equivalent to
.
So we can simplify this by adding the exponents
and
.
Converting
into fourths gets us
.
.
So we now have
.
When we have a number to a fraction power, it's the same thing as taking the denominator root of the base to the numerator power.
Basically, this becomes
. (The numerator is what we raise x to the power of, the denominator is the root we take of that).
Hope this helped!
