Answer:
Step-by-step explanation:
The discriminant of a quadratic equation is b² - 4ac.
Here, a = 1, b = 3 and c = 8, and so the value of the discriminant is:
3² - 4(1)(8) = 9 - 32 = -23
The discriminant is -23 in this case.
A negative discriminant indicates that the roots will be complex.
Answer:
x=.5
Step-by-step explanation:
First, you need to isolate the variable term, so you have to move -5 over to the other side. Since it is subtraction on this side, you add 5 to both sides to cancel out the -5, and add it to the other side.
Now we have 10x=5. To solve for the variable, we have to divide by the number in the variable term. In this case, it is 10. 10/10 is 1, so now x is alone. We have to do the same thing on the other side. 5/10 is .5.
That's the answer! It's x=.5!
Answer:
y = -4x+7 is the equation simplified and answer choice A is the right answer.
Step-by-step explanation:
Your equation: y - 6 = -4(x+1)
Your Objective: You need to simplify the original equation and find another equation that is equivalent to the original equation.
Let's focus on the -4(x+1) side first.
This needs to have the distributive property applied.
Take -4 and multiply it by x and 1.
You should have -4x+1
Your equation now:
y - 6 = -4x+1
We want y to be by itself.
So add 6 to both sides.
y = -4x+1+6
Use PEMDAS
y = -4x+7
The first answer choice "A" is correct.
