-23-10x ≤ 47 (Solving two step inequalities)
Answers
(x is greater than or equal to negative seven)
Explanation:
You have to add 23 to both sides making it 70. Then, when you divide or multiply with these inequalities you flip the sign. So when you divide a negative and a positive number, the answer is always negative. So 70 divided by -10 is -7

_____× \(10^{-3}\) is 2,000 times greater than 1.9 × \(10^{-6}\). It is also ____ times greater than 9.5 × \(10^{-4}\).
Answers
Answer:
you do it yourself
Step-by-step explanation:
3.9 x \(10^{-3\) is 2,000 times greater than 1.9 × \(10^{-6\) .
It is also 4 times greater than 9.5 × \(10^{-4\) .
What are exponents and power?Exponents and powers are ways used to represent very large numbers or very small numbers in a simplified manner.
For example, if we have to show 3 x 3 x 3 x 3 in a simple way, then we can write it as \(3^4\), where 4 is the exponent and 3 is the base.
Given:
a x \(10^{-3\) is 2,000 times greater than 1.9 × \(10^{-6\).
So, we have to find the value of a
a x \(10^{-3\) / 1.9 × \(10^{-6\) = 2000
a x \(10^{-3 - (-6))}\) = 2000 x 1.9
a x \(10^{-3 + 6)}\) = 2000 x 1.9
a x 10³ = 2000 x 1.9
a x 10³ = 3800
a = 3800 / 1000
a= 3.8
Again, 3.8 x \(10^{-3\) /9.5 x \(10^{-4\)
= 0.4 x 10
= 4

The Equation can be written like this:
f(x) = 1/(4p)(x -h)^2 +(k-p)
where (h, k) is the focus, and p is half the distance between focus and directrix. Here, (h, k) = (2, 6) and p=(6-(-2))/2 = 4. So the equation is ...

To find f(f^(-1)(9)), we need to first find f^(-1)(9), the inverse of f(9).
Given that f(4) = 9, we know that f^(-1)(9) is equal to 4.
Therefore, f(f^(-1)(9)) is equivalent to f(4).
Given that f(4) = 9 according to the problem statement, we can conclude that f(f^(-1)(9)) = 9.

Joseph drove to his grandmothers house which is 279 miles away in 4.5 hours.If he continues at the same speed, approximately how long will it take him to drive 325 miles?
Answers
Answer: 5.24
Step-by-step explanation:
I like to set these up as ratios.
279 miles/4.5 hours = 325 miles/ x hours
Then cross multiply
279x = 4.5 x 325
279x = 1462.5
divide both sides by 279
x = 5.24 hours
You can also solve 279 miles/4.5 hours to get the miles per hour driven, then divide 325 by that number:
279/4.5 = 62mph
325/62 = 5.24
Answer:
5•24hours
Step-by-step explanation:
I like to set these up as ratios
279miles/4•5hours=325miles/×hours
then cross multiply
279×=4•5×325
279×1462•5
divide both sides by 279
×=5•24hours
you can also solve 279miles/4•5hours to get the miles per hour driven،then divide 325 by that number:
279/4•5=62mph
325/62=5•24

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

The dimensions of a scale drawing of the flag are 10 centimeters and 16 centimeters.
What is a scale factor?The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).
Given:
The scale factor is 1/6.
A rectangular flag is 60 centimeters by 96 centimeters.
To find the dimension of new flag:
60 x 1/6 = 10 centimeters
96 x 1`/6 = 16 centimeters.
