Answer:

Step-by-step explanation:

The question you should be asking yourself is, "80% of how many doctors is 240?"  Algebraically, 80% is .8, "of" is multiplying, "how many doctors" is our unknown, and "is" means equals.  Putting that all together:

.8x = 240 so

x = 300

What is bigger 0.075 or 0.75 and why
hodyreva [135]

Answer:

0.75

the reason is because if we round it to the nearest tenth . 0.75 becomes 0.8. and 0.075 becomes 0.1 .  0.8 is 8/10th of 1. 0.1 is 1/10th of 1. therefor 0.8 is bigger

Given the parent function of f(x) = x³, what is the value of k in the translated graph of f(x - h) + k?
jekas [21]

The value of k in the translated graph of f(x - h) + k is; k = 2

<h3>How to carry out Translations on Graphs?</h3>

We are given the parent function of f(x) = x³.

Now, the point (0, 0) in the graph of f(x) is the point (3, 2) in the translated graph. Thus;

The rule of translation is;

(x, y) → (x + 3, y + 2)

That means;

The translation is 3 units to the right and 2 units up

The equation of the translated graph is equal to;

f(x) = (x - 3)³ + 2

Thus;

The value of k is equal to 2.

What is the x-intercept of the equation 3x - 2y = -12 ​
muminat
X=2/3y-4

EXPLANATION
3x-2y=-12
You take -2y to the other side
It becomes 3x=2y-12
Then you divide 3
X=2/3y
-12/3=-4
X=2/3y-4
