Answer:
-4
Step-by-step explanation:
Solve this like a normal equation. Pretend the ≤ is an equal sign. Then isolate the variable. Subtract 7 from both sides, and that will give you -4

f(x) = 2x – 1 What is f(13)?
Answer:
f(13) = 25Step-by-step explanation:
f(x) = 2x – 1
To find f(13) substitute the value of x that's 13 into f(x). That is for every x in f (x) replace it with 13
We have
f(13) = 2(13) - 1
= 26 - 1
We have the final answer as
f(13) = 25Hope this helps you

Answer:
x=-2
Step-by-step explanation:
2(x+3)-10=4x
2x+6-10=4x
6-10=2x
-4=2x
-2=x
Answer:
x = -2
Step-by-step explanation:
First distribute the 2 with x and 3
Equation should look like... 2x + 6 - 10 = 4x
Second combine like terms, 6 and -10
Equation should look like... 2x - 4 = 4x
Third bring 2x to the other side making it -2x and subtract it from 4x
Equation should look like... -4 = 2x
Last divide -4 and 2.
Equation should look like... x = -2

Imagine a population of 100 individuals, with the initial frequencies A1 = 0.7 and A2 = 0.3. If A1 and A2 are selectively neutral what is the probability that the A2 allele will drift to fixation?
a. 70%
b. 30%
c. 3%
d. 0
Answer: b. 30%
Step-by-step explanation:
given data:
population size (n) = 100
A1 = 0.7
A2 = 0.3
if A1 and A2 are selectively neutral, the probability that A2 would drift to fixation
= 0.3
= 30%
there is a. 30% chance that A2 would drift towards fixation.

-2x^2+8x-9+4x+7x^2+2
Answer:
Add like terms
Step-by-step explanation:
You want to combine the squared, the variables, and the constants.
Combine -2x^2 and 7x^2 to get 5x^2
Then combine 8x and 4x which is 12x
Then combine -9 and +2 which is -7.
You should get 5x^2 + 12x - 7.
Keep in mind you can only combine like terms that are in the same equals barrier
For example: You can combine 8x + 3 + 2x = 0
but not 8x +3 = 2x +0 because they are on different sides of the equal sign.

If g(x)=x^2+5x find the value g(-2)+2
Answer:
-4
Step-by-step explanation:
g(-2) = (-2)^2 + 5(-2)
g(-2) = 4 - 10
g(-2) = -6
and
g(-2) + 2
-6 + 2 = -4
Answer:
-4
Step-by-step explanation:
g(x)=x^2+5x
First find g(-2) by letting x=-2
g(-2) = (-2)^2 +5(-2)
= 4 -10
= -6
g(-2) +2 = -6+2 = -4
12) Twenty cubic feet of marble can weigh 3400 pounds, plus or minus 100
pounds. Write and solve an absolute-value inequality for the possible weights of a
cubic foot of marble.
Answer:
Let's suppose that one cubic foot of marble is x.
20x = 3400
But because the weight has a range of +-100, then 20x is between 3300 and 3500. Write it like this:
3300<20x<3500
Divide by 20:
165<x<175
The meaning of this is that one cubic foot of marble weight between 165 and 175 pounds
The obtained inequality shows that one cubic foot of marble weight between 165 and 175 pounds.
Given that, twenty cubic feet of marble can weigh 3400 pounds, plus or minus 100 pounds.
What is an absolute-value inequality?Absolute value inequalities are inequalities in algebra that involve algebraic expressions with absolute value symbols and inequality symbols. In simple words, we can say that an absolute value inequality is an inequality with an absolute value symbol in it. It can be solved using two methods of either the number line or the formulas. An absolute value inequality is a simple linear expression in one variable and has symbols such as >, <, ≥, ≤.
Now, the weight has a range of ±100, then 20x is between 3300 and 3500.
That is, 3300<20x<3500
Divide the inequality by 20.
So, 165<x<175
Therefore, the obtained inequality shows that one cubic foot of marble weight between 165 and 175 pounds.
