Answer: x^2 + 6x – 7 = 0
The solutions x = -7 and x = 1 can be written as:
(x+7)(x-1) = 0
(Because you find the solution values for x from the brackets e.g (x+7) to get x=-7, dunno how to explain it better sry)
From which you can expand the brackets and find the answer in quadratic form.
(x+7)(x-1) = 0
Expand the brackets
x^2 + 7x – x – 7 = 0
x^2 + 6x – 7 = 0
Fifty two thousand fifty two is equal to 52,052.
Anwser: (-1,-5)
Why:
All you have to do is plug in the coordinates into the equation...
(5,10):
10+5=2(5+1)
15=10+2
15=12
This is false so this ordered pair isn’t a solution
(-1,-5):
-5+5=2(-1+1)
0=-2+2
0=0
This statement is true therefore this ordered pair is a solution and is the only solution.
Answer:
8+5=13 and 8+9=17 or (8+5) - (8+9) =-4
Step-by-step explanation:
Answer: 2.67 donut/minute
To find the average rate, you need to know the donut production and the time needed. In this question, the unit used is dozen donut and minutes. Assuming you want the rate to have donut/minute then the calculation would be:
Rate:
4x12 donuts / 18 minute
48 donut /18 minute
2.67 donut/minute
