Answer:
The value of x = 1
Step-by-step explanation:
2x+3 = 5
=> 2x = 5-3
=> 2x = 2
=> x = 2/2
=> x = 1
Answer:
No because of the 3xy term. For an equation to be considered linear there has to be one y value for every x value given
The solutions or roots to this equation is found by solving for x. We can do this a couple ways either by FOIL or quad formula
3x^2+6x+6=0
3(x^2+2x+2)=0
x^2+2x+2=0 we cant FOIL this out so we use the quad formula
x= [(-b+\-sqrt(b^2-4ac))/2a]
x= -2+\- sqrt(4-4(1)(2))/2(1)
x= -1 +i , -1 - i
So we have complex roots since our quad formula returned a negative number. Whenever the quad formula answer is positive we have two roots/solutions, when it is zero we have one root/solution, and whenever it is negative we have Complex roots/solutions
Hope this helps. Any questions please just ask. Thank you.
Complete the square: x^2 + 24x = 17
Identify the coefficient of x. It is 24. Take half of that coefficient: 24/2 = 12.
Now add the square of 12 to both sides of x^2 + 24x = 17
x^2 + 24x + 144 = 17 + 144
Write in factored form:
(x + 12)^2 = 161
Taking the square root of both sides:
x+12 = plus or minus
Answer:
Hmm, I think the answer is 57.5.
Step-by-step explanation:
Since 46 = 3/4, we divide 46 by 4 to get one fourth. That is 11.5 . Then, multiply it by 4 to get by one minute. 11.5 x 4 = 57.5
