Answer:
The remaining solution to the equation is x = 1
Step-by-step explanation:
2x^2 + x - 1 = 2
First set the equation to zero by subtracting 2 from each side:
2x^2 + x - 1 - 2 = 2 - 2
2x^2 + x - 3 = 0
Factor the left side of the equation:
2x^2 + x - 3 = 0
(2x + 3)(x - 1) = 0
Now set each factor to zero and solve:
2x+ 3 = 0
2x+ 3 - 3 = 0 - 3
2x= -3
2x/2= -3/2
x= -3/2 (The given expression)
x - 1 = 0
x - 1 + 1 = 0 + 1
x = 1
Since we already knew x = -3/2, the missing solution is x = 1.

Answer:
The situations that can be represented as an absolute value of 10 are:
- Determine the size of Harold’s debt if he owes $10.
- Determine how far −10 is from zero on a number line.
- 10 degrees is how many degrees above zero?
Step-by-step explanation:
- Determine the size of Harold’s debt if he owes $10.
Even though he owes $10, which is reflected as -$10, the size of the debt is the absolute value ($10).
- Determine how far −10 is from zero on a number line.
The distance is expressed in positive numbers, or using the absolute value.
- 10 degrees is how many degrees above zero?
The distance of the temperature is expressed in positive numbers, or using the absolute value.
Answer:
a. 3 and 56, respectively.
Step-by-step explanation:
The computation of the degrees of freedom for the numerator and denominator for the critical value of F is given below:
k = 4
n = 15
Total degree of freedom is
= nk - 1
= 59
For numerator, it is
= k -1
= 4 - 1
= 3
and for denominator it is
= T - (k -1 )
= 59 - 3
= 56
Answer: A) Megan’s jump is more impressive because a positive z-score means that the jump was longer than the competitions’ jumps, and her z-score is greater than Janae’s.
