Answer: immma guess that its c
super sorry if im wrong
Step-by-step explanation:
<span>The general form of quadratic equation with real
coefficients and leading coefficient 1, has x = -bi as a root
=> x = <u>-b + </u></span><u>√ b^2 – 4 ac</u><span>
2a
It is also written as:
=> ax^2 + bx + c = 0
Quadratic equation involves unknown numbers which is x, the numbers which a, b
and c are called coeffecients.
There are also quadratic factorization where you factor the polynomial give to
be able to get the value of the equation.</span>
First, you drive 123km per day, and they ask for in a week.
There are 7 days in a week, we have to multiply 123 by 7, which equals 861.
=km per week 861
Now, we need to find out how much cost the gas. Gas cost 1.10 euros per-liter, and this problem wants us to assume that 1euro = 1.26 dollars.
So, we divide 1.10 by 1.26 which is 0.87.
=gas cost 0.87 per liter.
Next, this person goes 31.0 mi/gal per stop.
To get the answer we need to divide 861 the full distance in a week and divide it by how many stops nee to be made which is each 31 mi/gal.
So, 861/31 = 27.77 and now we times 0.87 by 27.77 to get gas cost.
=24.16
Answer:
y < -2
Step-by-step explanation:
2y < -4
Divide both sides by 2.
y < -2
Hello there!
The answer would be C since we are looking to find how far she ran based on the amount of miles that has passed.
As stated above, 6 minutes. However to find out how far she runs we have to change the speed to miles per minute.
6 minutes per mile is equal to 1/6 of a mile per minute
Formula for Distance is speed x time
The distance is d, the time is t and the speed is 1/6.
Plug it in:
d = 1/6t
Lastly, multiply by 6 on both sides.
d x 6 = 1/6t x 6
1/6 x 6 = 1t
6d = 1t
Answer: t= 6d
