Step 1 : Simplify both sides
-5(6a+21)=-15
(-5)(6a)+(-5)(21)=-15
-30a-105=-15
Step 2 : Add 105 to both sides
-30a-105+105=-15+105
-30a=90
Step 3 : Divide both sides by -30
-30a=90

-30 -30
a = -3
Answer:
Right 2, up 3
Step-by-step explanation:
In the vertex form transformations....
f(x) = a(x-h)²+k
- a - indicates <em>vertical stretches</em>, <em>compression</em>, and/or a <em>reflection across the x-axis</em>.
- h - indicates only on the <u><em>x-axis</em></u>. Negative = Goes right, Positive - goes left
- k - indicates only on the y-axis. Positive = up, negative = down
Hello there! Your answer is k=2000.
When dividing by ten, you are essentially just taking off one of the zeroes. So, think: what number are you taking one zero off of to get 200? Well, 200 with one more zero added on to it is 2000, so 2000 put into 10 groups is equal to 200! I hope this helps and have a great rest of your day! :)
