Answer:
Inequality: 8.25x + 54 = 9.75
Step-by-step explanation:
Why?
It will take 36 hours for David to have as much as Fatima.
David :
Initial saving = 54
Pay per hour = $8.25
While Fatima :
Pay per hour = $9.75
Let number of hours worked = x
David's total = $8.25x + 54
Fatima's total = 9.75x
In other to have the same amount :
8.25x + 54 = 9.75x
The like terms :
8.25x - 9.75x = - 54
-1.5x = - 54
x = - 54 / - 1.5
x = 36
Therefore, it’ll take 36 hours for David to have as much as Fatima.
<em>Presuming you mean y = -2x^2 - 8x - 13</em>
Firstly, put the x terms in parentheses and factor out -2:
Next, we want to make what's inside those parentheses a perfect square. To do this, divide the x coefficient by 2 and square that result. In this case, that result is 4. Add 4 to the inside of the parentheses, and add 8 to the outside of the parentheses to balance it out. (Since when foiled, 4 x -2 = -8)
Next, factor what's inside the parentheses, and <u>your final answer will be </u>
There is no image, but based off of actual recipes i would say probably C

I believe your answer is 4
Step-by-step explanatio
Answer:
69 students were advanced and 184 were regular
Step-by-step explanation:
begining
advance 3: regular 8
after exam
advance 4 (92students) : regular 7 (92/4=23; 23*7=161 students)
So total students we have 161+92=253,
remember we have advance 3: regular 8 so
253/(3+8)=253/11=23
23*3=69, 23*8=184
