dowload this app now hehe:) p.h.o.t.o.m.a.t.h
The bottom one is 70 the top one is 60 I’m not good at explaining things so sorry if you need it
The time of takeoff of this hovercraft would be 0 seconds, as if you were starting a timer. So, if you plug in 0 for x (unit for seconds) in your equation, it will look like this:
h(0) = -3(0 - 3)² + 108
Parenthesis first
h(0) = -3(-3)² + 108
Exponents next
h(0) = -3(9) + 108
Multiplication
h(0) = -27 + 108
Combine like terms
h(0) = 81: The height of the hovercraft at the time of takeoff is 81 meters!
Hope this helps :)
Fraser got 14 questions right
questions correct 70/5 = 14
—— ——
total questions 100/5 = 20
therefore he got 14 questions right
you divide 100 by 5 because percents are always out of 100 and that gets you 20 which is how many questions the spelling bee had
then you do the same to the top (divide by 5) and get 14
14/20 questions were answered right
70% of the questions were correct
Answer:
Below
Step-by-step explanation:
Notice that x is between 10 and -10 but takes only the values that are integers.
The inequalities:
● we can write an inequality that includes all these values.
● -10 《 x 《 10
This is a possible inequality
Multiply both sides by 2 and you will get a new one:
● -20 《 2x 《 20
You can multiply it by any number to generate a new inequality.
Or you can add or substract any number.
