Answer:
-2
Step-by-step explanation:
If we replace all the spots where x is with -3, we get this: (-3)^2 + 5(-3) + 4. Then we get... 9 + -15 + 4 which equals -2
5(x + 3) + 9 = 3 (x - 2) + 6
5x + 15 + 9 = 3x - 6 + 6
5x + 24 = 3x
5x - 3x = -24
2x = -24
x = -24/2
x = - 12
So to solve a,
You already have the first two answers which are 65 and 90. Since a tríenle always has to equal 180 you just add 65 and 90 and the subtract that number by 180 and that’s your other missing angle.
Both triangles are identical so you just have to insert the answers from the right triangle onto the left triangle.
A is the only one that I knew how to solve, sorry
Answer:
0 ≤ x ≤ 10
Step-by-step explanation:
The function representing the spread of virus is:
Where x represents the number of hours after 1:00 pm
So, at 1:00 pm "x" will be equal to 0. So the domain will start from x = 0
According to the given statement, the virus spreads from 1:00 pm to 11:00 pm. So, the number of hours starting from 1:00 pm and ending on 11:00 pm will be the Domain. 11:00 pm means 10 hours after 1:00 pm i.e. x = 10
So, the domains starts at x = 0 and ends at x = 10. Therefore, the correct answer is 0 ≤ x ≤ 10
Answer:
((3 / 14) * 3) / 14 = 9 / 196
Step-by-step explanation:
Reduce 9/196 to lowest terms 9 196 is already in the simplest form. It can be written as 0.045918 in decimal form (rounded to 6 decimal places).
