Answer:
use geogebra app you can install it on your pc
pls follow me
Step-by-step explanation:
Let the first number be <em>x</em>
Let the second number be <em>y</em>
<em>x</em> = y - 9
3x = 4y + 12
3x - 4y = 12
3(y - 9) - 4y = 12
3y -4y - 27 = 12
-y = 12 + 27
-y = 39
y = -39
x = y - 9
x = -39 - 9 = -48
Answer:
1 and 3
Explanation:
We are given that:
f(x) = 2ˣ - 2
g(x) = 3x - 3
We want to get the solution of f(x) = g(x). This means that we want to get the values of x that make the two solutions equal
Since the choices givens all belong to the given table, we can simply get the solution by examining the table and comparing f(x) with g(x) at each value:
At x = -1:
f(x) = -3/2
g(x) = -6
f(-1) is not equal to g(-1)
Therefore, this is not a solution
At x = 0:
f(x) = -1
g(x) = -3
f(0) is not equal to g(0)
Therefore, this is not a solution
At x = 1:
f(x) = 0
g(x) = 0
f(1) is equal to g(1)
Therefore, this is a solution
At x = 2:
f(x) = 2
g(x) = 3
f(2) is not equal to g(2)
Therefore, this is not a solution
At x = 3:
f(x) = 6
g(x) = 6
f(3) is not equal to g(3)
Therefore, this is a solution
At x = 4:
f(x) = 14
g(x) = 9
f(4) is not equal to g(4)
Therefore, this is not a solution
At x = 5:
f(x) = 30
g(x) = 12
f(5) is not equal to g(5)
Therefore, this is not a solution
Based on the above, the only solutions among the given choices are 1 and 3
Hope this helps :)
This question is incomplete, the complete question is;
Trevor is interested in purchasing the local hardware/electronic goods store in a small town in South Ohio. After examining accounting records for the past several years, he found that the store has been grossing over $850 per day about 60% of the business days it is open. Estimate the probability that the store will gross over $850 at least 6 out of 10 business day
Answer:
P( at least 6 out of 10 business days ) = 0.6312
Step-by-step explanation:
Given the data in the question;
p = 60% = 0.6
q = 1 - p = 1 - 0.6 = 0.4
Using Binomial distribution;
P( X = r ) =
where
we substitute
P( at leas 6 ) = P(6) + P(7) + P(8) + P(9) + P(10)
= [¹⁰C₆ × 0.6⁶ × 0.4⁴] + [¹⁰C₇ × 0.6⁷ × 0.4³] + [¹⁰C₈ × 0.6⁸ × 0.4²] + [¹⁰C₉ × 0.6⁹ × 0.4¹] + [¹⁰C₁₀ × 0.6¹⁰ × 0.4⁰]
= [0.250] + [0.214] + [0.1209] + [ 0.0403] + [ 0.00604 ]
= 0.6312
Therefore, P( at least 6 out of 10 business days ) = 0.6312

Hello!</h2>
The answer is:
The correct option is:
C)
<h2>
Why?</h2>
To solve the problem, we need to remember the product of powers with the same base property, the property is defined by the following relation:
If we are multiplying two or more powers with the same base, we must keep the base and add/subtract the exponents.
So, we are given the expression:
We can see that both powers have the same base (4), so solving we have:
Hence, we have that the correct option is:
C)
Have a nice day!
