The inequality of this question would be 4
Answer:
2 ± i
Step-by-step explanation:
by 5, I assume you mean +5
x² - 4x + 5 = 0
x = (-b±(√(b²-4ac)) / 2a
x = (4 ± (√(16 - 20)) / 2
x = (4 ± (√(-4)) / 2
√-4 = √4√-1 which is 2i
x = (4 ± 2i) / 2
x = 2 ± i
Answer: No she used the wrong slopes when graphing the equations
Step-by-step explanation:
Answer:
3.3 miles per hour. this is because speed is equal to distance travelled divided by time taken. so you calculate how many minutes he spent that is from 9:15 to 10:00 . since you are calculating in miles per hour, you convert the minutes to hours and do the working according to the formula
