Answer: 33 cookies.
Step-by-step explanation: To find the 75% of 44 cookies, use these steps:
Step 1: Our output value is 44.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above, 44 = 100%.
Step 4: Similarly, x = 75%.
Step 5: This results in a pair of simple equations:
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right-hand side) of both equations have the same unit (%); we have:
= 
Step 7: Again, the reciprocal of both sides gives:
= 
Therefore, 75% of 44 is 33. Thus, it is 33 cookies.
Answer: y=(x+7)^2-9 where h=-7 and k=-9
Step-by-step explanation:
We need to "complete the square",
A perfect square trinomial formule is:
(a+b)^{2}=a+2ab+b^{2}
in this case, a is x and to find -h we know that 14x is 2*x*(-h) so:
14x=2*x*(-h)
14x/2x=-h (x is simplified)
7=-h => h=-7
we add +7^2 and -7^2, to the first equation:
y= <u>x^2 + 14x + 7^2</u> -7^2 + 40 (the underlined section is a perfect square trinomial already)
y=(x+7)^2 <u>-49 +40</u> (addition)
y= (x+7)^2 - 9
Answer:
y= -2/5x - 6
Step-by-step explanation:
Use Rise/Run with any of the given points! You go up two, left 5. That proves the slope is -2/5. The line hits the Y axis at -6, so the y-intercept is -6!
I hope this helps!!
