Answer: If Tom finished the race in 95 seconds and Robert finished 20 seconds before Tom, Robert finished in 75 seconds.
The expression that shows this is 95-20=75.
Answer:
The vertex would be (-3, -1)
Step-by-step explanation:
Since this is in vertex form already, a(x-h)^2+k where h is the x value of the vetex, and k is y.
We would take the opposite of +3 and get -3, which gives us our x cordinate.
We don't change the k value, so it just stays -1, giving us our y value.
Therefore, the vertex is at (-3, -1)
Hope this helps!
Answer:
m= 2/3
Step-by-step explanation:
up 2 right 3
y= 2/3x-2
Answer:
6x
Step-by-step explanation:
Since 2 sides are equal to 3x-3, multiply 3x-3 by 2.
=6x-6
Subtract 18x+6 - 6x-6
= 12x
Since 2 there are 2 sides missing, 12x divided by 2
=6x
A distinct real solution is a solution to an equation that occurs once, and differs in value from other solutions. For example, in the equation above there are two distinct real solutions: x = − 13 2 and x = 13 2 . Since they are different, real numbers, the equation has two distinct real solutions.
The value of the discriminant determines how many solutions the quadratic will have. Equation 1: the discriminant was zero, there was only 1 solution. Equation 2: the discriminant was a negative number, there was no solution. Equation 3: the discriminant was a positive number, there were two solutions.
