What are the solutions to 0=x^2-x+1?

kumpel [21]

Answer: No solutions

Step-by-step explanation:

There are no solutions to 0 = x² - x + 1.

[Method One]

We can solve this by rewriting the equation, but it is quicker to graph it when there are no solutions. See attached.

[Method Two]

I said we can solve this by solving an equation, here it is. We will use the quadratic formula since the equation given is already in the proper form.

$\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}$

$\displaystyle x=\frac{1\pm\sqrt{(-1)^2-4(1)(1)} }{2(1)}$

$\displaystyle x=\frac{1\pm\sqrt{-3} }{2}$

-> Negative numbers don't have real square roots, so there is no solution

Maria runs 7 miles in 80 minutes. at the same rate, how many miles would she run in 64 minutes

Alex777 [14]

Answer:

5.6 miles

Step-by-step explanation:

Firstly, we need to find the unit rate (the number of miles in 1 minutes).

To get this, we need to divide total miles ran (7 miles) by the total minutes taken (80 minutes). Thus, we will have MILES PER MINUTE.

7 miles ÷ 80 minutes = 7/80 miles per minute

Now,

We want number of miles in 64 minutes. Since we know "PER MINUTE", we simply multiply that with 64 to get number of miles in that amount of time.

THus,

$\frac{7}{80}*64=\frac{56}{10}=5.6$

So, in 64 minutes, Maria can run 5.6 miles

find two numbers, both smaller than 100, that have common multiple of 450 and highest common factor of 15

Alex_Xolod [135]

Answer:

hello :

90 = 15×6

75 = 15× 5

highest common factor of 90 and is 15 because highest common factor of 5 and 6 is 1

90 = 3² ×2×5

75= 5^3

common multiple of 90 and 75 is : 3²×2×5² = 450

90 and 75 both smaller than 100.
