Answer:
Slope= -5/3
Step-by-step explanation:
Y= x^2+2x-8 (the x^2 is x squared)
Answer:
Step-by-step explanation:
r+58
Let r=3
3+58
61
Answer:
16
Step-by-step explanation:
put (2) in for (a) and (6) in for (b)
add the two numbers in parentheses then multiply the product by (2)
Subtract 3 from both sides so that the equation becomes -2x^2 + 5x - 13 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -5 ± √((5)^2 - 4(-2)(-13)) ] / ( 2(-2) )
x = [-5 ± √(25 - (104) ) ] / ( -4 )
x = [-5 ± √(-79) ] / ( -4)
Since √-79 is nonreal, the answer to this question is that there are no real solutions.
