Answer:
Step-by-step explanation:
So the question here is asking you to use the quadratic formula which is expressed as:
A quadratic can generally be expressed as:
So using the equation you gave:
We can identify the following values: a=1, b=-5, c=-1
Btw the equation explicitly write "1" as the coefficient of x, but since it's not provided it's implied that it's 1.
So plugging in the known values, we get the following equation:
The last step just consists of taking the + and - solution, and since it asks for exact solutions you leave the 29 under the radical, and you don't approximate. There is no further simplification that can be done here.
Answer:
Daniel will save $1.18
Step-by-step explanation:
First, find the cost of the name-brand flour with the coupon:
Subtract 1.44 from the original price of 9.12:
9.12 - 1.44
= 7.68
So, the price of the name-brand flour with the coupon is $7.68
Now, find how much he will save by finding the difference between this price and the price of the store brand flour:
8.86 - 7.68
= 1.18
So, Daniel will save $1.18
Maybe 11x? i dont really know, thats all the info we get
Answer:
5.75
Step-by-step explanation:
Rewrite 7/8 as a decimal by dividing 7 by 8:
7/8 = 0.875
Now to find how much further she has to run subtract where is now from the total distance:
0.875 - 0.3 = 0.575
She needs to run 0.575 miles more
