Answer:
Y≤-3/4x+2
Step-by-step explanation:
less than because the bottom of the line is shaded
equal to because the line is solid
slope you go down three and go right four which is negative
y intercept is where x=0
I would say C.
A and B make no sense, you want to divide the group randomly because you want to test the new medicine. D is a bit more logical than A and B but still can't, because that isn't random.
Ok, there is an equation you can use to solve it.
n is a number.
p is also a number, but different to n.
Therefore:
<u></u>
So all together there were 54 girls and 42 boys in the theatre.
54 + 42 = 96
That's 96 children in total. (Answer)
7:9 = 42:54
<h3>Answer:</h3>
- Vertical scaling by a factor of 1/2
- Vertical translation 5 units downward
<h3>Explanation: </h3>
Multiplying a function value by a constant effectively applies a vertical scale factor to that function. The scale factor is the constant. Here, the parent function x² is multiplied by 1/2 (to give 1/2x²). The vertical scale factor is 1/2.
Adding a constant to a function value causes a vertical translation of that function. Every output value is moved upward (translated) by the amount that is added. Here, that added amount is -5, so the vertical movement is downward 5 units.
For f(x) = x², vertical scaling by a factor of 1/2 makes it 1/2x². Translating that downward 5 units makes it ...
... y = 1/2x² - 5 . . . . . . . . . x² scaled and translated
Step-by-step explanation:
The first one will be:
7x^6 - 7x^5 +28x - 4x² - 60
And the second:
-9x⁴-3x²-4x²+5x
