Answer:
2:3
Step-by-step explanation:
A total of 30 students with 12 girls so its 12/30 & its the balance of 18 boys or 18/30
12:18 ÷ by 2 on both sides is.6:9 & 2:3, Answer is Ratio of 2:3.
-5x-12>6x-4
To Solve the inequality we need to get x alone
-5x-12>6x-4
first we remove -12, for that we add 12 on both sides
-5x-12+12>6x-4+12
-5x > 6x +8
Now subtract 6x from both sides
-5x -6x> 6x-6x +8
-11x > 8
Divide by -11. when we divide by -11 we flip the inequality . so > becomes <
We need to give the answer in interval notation.
x is less than -8/11 so x value starts from -8/1 and goes to -infinity(left)
So interval notation is (-∞, )
The answer is 60,000. because it would equal six hundred thousand, and that divided by 10 is 60,000

Answer:
f(0)= 3-2^0 --> 3-1 =2
f(-1)= 3 - 2^-1 --> 3 - 1/2 -->5/2 = 2,5
Step-by-step explanation: F(0) means if x=0 so the first you just take x and replace it with 0 and the second you replace x by -1.
Something that is elevated by 0 is always going to be 1
Hope this make sense :)
