Answer:
x = 2, -7
Step-by-step explanation:
We can start by finding two numbers which <em>add </em>to make 5 and <em>multiply </em>to make -14. The only two which fit the bill are 7 and -2, and using that fact, we can break apart the middle term of the polynomial:
From the , we can factor out an x, and from the , we can factor out a 7, giving us
Or, factoring out the ,
Solving gives us , and solving gives us , so our solutions are
Answer: 13.4 kilograms
Step-by-step explanation:
Because apples, bananas, and peaches are all fruits, all we need to do is add them together to find the total.
8.5 + 3 + 1.9 = 13.4
Be careful! Sometimes, the question will include objects that <em>aren't</em> fruits. Don't include those in your equation if it asks for the weight of the fruit (like in this question). That's extra information that you'll need to look out for in the future.
Don't forget your units (kilograms) and good luck!
Answer:
715.5

Hope this helps :)
He sold 28 at 0.75 cents and sold 21 at 0.99 cents.
0.85 is between 0.75 and 0.99 so he sells between 21 and 28 donuts.
0.85 is closer to 0.75 ,so the number should be closer to28.
The answer should be b)25
Answer:
2
Step-by-step explanation:
The slope of the line is found by
m = (y2-y1)/(x2-x1)
= (-2-2)/(-4--2)
= -4/ (-4+2)
= -4/-2
= 2
