Answer:
x = 2, Inverse property of subtraction
Step-by-step explanation:
Simplifying
2(x + 3) = 10
Reorder the terms:
2(3 + x) = 10
(3 * 2 + x * 2) = 10
(6 + 2x) = 10
Solving
6 + 2x = 10
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6' to each side of the equation.
6 + -6 + 2x = 10 + -6
Combine like terms: 6 + -6 = 0
0 + 2x = 10 + -6
2x = 10 + -6
Combine like terms: 10 + -6 = 4
2x = 4
Divide each side by '2'.
x = 2
Simplifying
x = 2
Answer:
x = 2
Step-by-step explanation:
Apply the distributed property, so it now looks like this: 2x + 6 = 10Subtract 6 to each side, so it now looks like this: 2x = 4Divide each side by 2 to cancel out the 2 next to x. It should now look like this: x = 2I hope this helps!

Answer:
J-¹(x)= x+6/5
or
J-¹(x)= x/5 + 6/5
Step-by-step explanation:
J(x)= 5x -6
•first separate your Y from the original equation like this
y= 5x-6
•second replace for x since we are talking about the inverse form
x= 5y-6
•third solve for y
x+6=5y-6+6
add 6 to both sides
x+6=5y
divide 5 to both sides
x+6/5=5y/5 (in your right side 5 cancels out)
it should look like this
x+6/5=y (you solved for y)
and now you write your answer like this
J-¹(x)= x+6/5
or
J-¹(x)= x/5 + 6/5

In the general population, one woman in eight will develop breast
cancer. Research has shown that 1 woman in 600 carries a mutation of
the BRCA gene. Eight out of 10 women with this mutation develop
breast cancer.
a) Find the probability that a randomly selected woman will develop
breast cancer given that she has a mutation of the BRCA gene. b) Find the probability that a randomly selected woman will carry the mutation of the BRCA gene and will develop and will develop breast cancer? c) are the events of carrying this mutation and developing Brest cancer independent or dependent?
Answer:
a) 8/10
b) [tex]0.001 \overline{33}[/tex]
c) Independent events
Step-by-step explanation:
The given information are;
The proportion of women than carries a mutation of the BRCA gene, P(A) = 1/600
The proportion of women in which the mutation develops breast cancer, P(B) = 8/10
a) The probability that a randomly selected woman will develop breast cancer given that she has a mutation of the BRCA gene is given as follows;
1 × P(B) = 1 × 8/10 = 8/10
b) The probability, P that a randomly selected woman woman will carry the mutation of the BRCA gene and will develop breast cancer is given as follows;
P(A) × P(B) = 1/600×8/10 = 1/750 = [tex]0.001 \overline{33}[/tex]
c) The events are dependent
Given that P(A) × P(B) = P(A∩B), the events of carrying the mutation and developing Breast cancer are independent events.

A truck driver has to make a delivery at
a location that is 230.2 miles away. She
drives an average of 55 miles each hour
for 3.25 hours. If the truck driver
continues at the same speed, will she
make it to the location in the next
hour?
A Yes, she only has 51.45 miles to go.
® Yes, she only has 52.55 miles to go.
© No, she still has 63.45 miles to go.
D No, she still has 64.65 miles to go.
Answer:
Option A is correct
Step-by-step explanation:
Speed of truck = 55 miles/hour
Time taken = 3.25 hours
Distance = Speed × Time
[tex]=55[/tex] × 3.25
[tex]=178.75[/tex]
But truck driver has to make a delivery at a location that is 230.2 miles away.
Distance left to be covered by a truck driver = [tex]230.2-178.75=51.45[/tex] miles
So,
Yes, if the truck driver continues at the same speed, she will make it to the location in the next hour such that she only has 51.45 miles to go.
Option A is correct
We want to see if the truck driver has enough speed to reach the destination or not. The correct option is A "Yes, she only has 51.45 miles to go."
Working with speeds:So we know that she needs to travel a total distance of 230.2 miles.
Now, remember the relation:
Speed*time = distance.
And she travels at an average speed of 55 miles per hour for 3.25 hours, so she traveled a distance of:
(55 mi/h)*3.25 h = 178.75 mi
Then the remaining distance is just:
230.2 mi - 178.75 mi = 51.45 mi
Will she make it in the next hour?
Well, yes, she travels at 55 miles per hour and she has 51.45 miles remaining, so yes, she will make it.
The correct option is A: "Yes, she only has 51.45 miles to go."

Given h(x) = -2x – 5, find h(-2)
Answer:
-1
Step-by-step explanation:
they gave you the value to x so all you have to do is plug it in
h(-2) = -2 (-2) - 5
h(-2) = 4 - 5
h(-2) = -1
Substituting the value, x = - 2 into the function, the value of the function h(-2) is - 1
Given the function :
h(x) = - 2x - 5At h(-2) :

Answer:
[tex]\boxed { x = -\frac{5}{2}}[/tex]
Step-by-step explanation:
To determine the value of [tex]x[/tex], write expression by using the following measurement from both [tex]\angle 1[/tex] and [tex]\angle 2[/tex] and solve:
[tex]\angle 1 = 20 + 5x[/tex]
[tex]\angle 2 = x + 10[/tex]
[tex]20 + 5x = x + 10[/tex]
Solve for [tex]x[/tex]:
[tex]20 + 5x = x + 10[/tex]
[tex]20 + 5x - x = x - x + 10[/tex]
[tex]20 + 4x = 10[/tex]
[tex]20 - 20 + 4x = 10 - 20[/tex]
[tex]4x = -10[/tex]
[tex]\frac{4x}{4} = \frac{-10}{4}[/tex]
[tex]\boxed { x = -\frac{5}{2}}[/tex]
So, the value of [tex]x[/tex] is [tex]-\frac{5}{2}[/tex].

∛-1000=-10
Answer:
-10
Step-by-step explanation:
First...
A cube root is to find a number that if multiplied three times by its self equals this number. (sorry a little confusing)
Next...
Forget about the negative for a little bit and look at it.
10*10*10=1000
Finally...
If 10 cubed is positive 1000 then -10 cubed is -1000.
So the answer is -10.

The next three terms of Sequence is 2, 7, 12.
What is Sequence?A grouping of numbers in a specific order is known as a sequence. On the other hand, a series is described as the accumulation of a sequence's constituent parts.
Each number in the sequence is called a term. In the sequence 1, 3, 5, 7, 9, …, 1 is the first term, 3 is the second term, 5 is the third term, and so on.
Given:
-18, -13, -8, -3,…
Now, the common difference = -13 - (-18)= -13 + 18 = 5
So, the formula for nth term will be
[tex]a_n[/tex] = -18 + 5(n-1)
Then, n= 5th term
[tex]a_n[/tex] = -18 + 5(5-1)
[tex]a_n[/tex] = -18 + 5(4)
[tex]a_n[/tex] = -18 + 20
[tex]a_n[/tex] = 2
and, n= 6th term
[tex]a_n[/tex] = -18 + 5(6-1)
[tex]a_n[/tex] = -18 + 5(5)
[tex]a_n[/tex] = -18 + 25
[tex]a_n[/tex] = 7
and, n= 7th term
[tex]a_n[/tex] = -18 + 5(7-1)
[tex]a_n[/tex] = -18 + 5(6)
[tex]a_n[/tex] = -18 + 30
[tex]a_n[/tex] = 12
Hence, the next three terms are 2, 7, 12.
