Answer:
x = ±i sqrt(3/2)
Step-by-step explanation:
2x^2+7 = 4
Subtract 7 from each side
2x^2+7-7 = 4-7
2x^2 = -3
Divide by 2 on each side
2x^2/2 = -3/2
x^2 = -3/2
There is no real solution, only imaginary solutions
Taking the square root of each side
sqrt(x^2) = sqrt(-3/2)
x = ±i sqrt(3/2)
Answer:
The rate is 140 miles per hour
Step-by-step explanation:
We can use the formula distance is equal to rate times time
The distance is 700 miles and the time is 5 hours
D =rt
700 = r*5
Divide each side by 5
700/5 = 5r/5
140 =r
The rate is 140 miles per hour
Answer: 1/8
Step-by-step explanation:
Multiply by the reciprocal which would be 1/2, so 1/4x1/2 would be 1/8
The answer to this function is M = 1/9 (The slope is "M").
