I need to know what this answer is

3. Write the expression 175 using radicals.

5√7

Step-by-step explanation:

What we want to do is first just put the 175 in a sqrt like this:

√175

Next we do prime factorisation to try and simplify further.

         175

      /          \

   25            7

  /     \

5         5

We can figure out that this out √5^2 times 7

we can cancel the sqrt and the squared and simplify to 5√7

So there is your answer, 5√7.

If you have any questions feel free to ask. Also for the prime factorisation the formatting may be off, sorry for the inconvenience and have a good day!

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
