When you're dividing exponents, you subtract. The numbers act the same however, so you can divide the values separately and then put them together at the end.
15 ÷ 3 = 5
x^6 ÷ x² = x^(6-2) = x^4
y³ ÷ y^8 = y^(3-8) = y^-5
So your final answer is 5x^4y^-5
I hope this helps!

When solving negative one over five (x − 25) = 7, what is the correct sequence of operations?
miv72 [106K]
-\frac{1}{5}(x-25) = 7       multiply 5 to both sides first
-(x-25) = 35                                     then expand the brackets
-x+25=35                                        make x the subject now;
-x=10

Plz help me I’m so confused 23 points plz explain it to me in sooo stuck
anzhelika [568]

Answer:

6. D

7. B

Step-by-step explanation:

Nancy takes a test that has two sections: essay and true/false. She scores 56 points on the essay. Each true/false question is 4 points. So x number of true/false is worth 4 points each or 4x.

Together her score will be 56 + 4x.

She wants to score more than 80 or > 80.

So her test can be represented as the inequality 56 + 4x > 80.

This is solved using inverse operations.

56 + 4x > 80

4x > 24

x > 6

This should be graphed as an open circle at 6 on the umber line pointing and shaded to the the right for numbers greater than 6.

Graph the image of this figure after a dilation with a scale factor of 1/3 centered at the origin.
posledela

Answer:

see attached diagram

Step-by-step explanation:

A dilation with a scale factor of \dfrac{1}{3} centered at the origin has a rule:

(x,y)\mapsto\left(\dfrac{x}{3},\dfrac{y}{3}\right).

Then the image of the triangle ABC is triangle DEF(see attached diagram) with coordinates

  • D\left(\dfrac{-3}{3},\dfrac{3}{3}\right)\Rightarrow D(-1,1);
  • E\left(\dfrac{3}{3},\dfrac{9}{3}\right)\Rightarrow E(1,3);
  • F\left(\dfrac{6}{3},\dfrac{6}{3}\right)\Rightarrow F(2,2).
