How do I Simplify 5(2x-4)-(-6x+3)
Answer: 16x-23
Step-by-step explanation:
1) Distribute the 5 to the first parentheses
10x-20-(-6x+3)
2) Distribute the negative sign
10x-20+6x-3
3) Combine like terms
16x-23
Answer:
Step-by-step explanation:
first you open up the parenthesis, to get:
10x-20-(-6x+3) = 10x-20+6x-3
then you subtract n both sides to get 16x -23

A rock climber's height, in feet, when climbing a shear wall can be expressed by the equation h=15t, where t is time measured in hours. Which best describes the proportional relationship?
Answer:
The climber moves 15 feet per hour.
Step-by-step explanation:
A rock climber's height, in feet, when climbing a shear wall can be expressed by the equation h=15t, where t is time measured in hours
h is distance and t is time.
[tex]\dfrac{h}{t}=15[/tex]
or
[tex]\dfrac{d}{t}=15[/tex]
Distance per unit time is equal to the velocity of an object.
velocity = 15 feet per socond
Hence, the climber moves 15 feet per hour.
Let f(x) = -3x + 2 and g(x) = 2x – 5;
compute g(f(x))
Answer:
g(f(x)) = -6x+6.
Step-by-step explanation:
It is given that,
f(x) = -3x + 2 and g(x) = 2x – 5
We need to find g(f(x)).
Put it into g(x).
g(f(x)) = 2(-3x + 2)+2
= -6x+4+2
=-6x+6
Hence, the value of g(f(x)) is -6x+6.

An apartment complex allows residents to have up to 3 dogs and up to 2 cats. The joint probability model for the number of dogs (X) and number of cats (Y) that a resident has, is given below. Given that a resident has 1 cat, what is the probability that the resident does not have any dog
Complete Question
The complete question is shown on the first uploaded image
Answer:
The correct option is the second option
Step-by-step explanation:
Let D be the event that a resident has a dog
Let C be the event that a resident has a cat
Generally according to Bayes rule the probability that a resident has no dog give that he/she has one cat is mathematically represented as
[tex]P(D' | C) = \frac{P ( D' \ n \ C)}{ P( C )}[/tex]
Here [tex]P(D' \ n \ C )[/tex] is the probability that a resident has one cat and no dog and from the table the value is
[tex]P(D' \ n \ C ) = 0.2[/tex]
and [tex]P(C)[/tex] is the probability of having one cat which is mathematically evaluated as
[tex]P(C) = P(C \ n \ D') + P(C \ n \ D) + P(C \ n \ 2D) + P(C \ n \ 3D)[/tex]
From the table
P(C \ n \ D') = 0.2
P(C \ n \ D) = 0.05
P(C \ n \ 2D) = 0.04
P(C \ n \ 3D) = 0.06
[tex]P(C) = 0.2 + 0.05 + 0.04 + 0.06[/tex]
=> [tex]P(C) = 0.35[/tex]
So
[tex]P(D' | C) = \frac{0.2}{ 0.35}[/tex]
=> [tex]P(D' | C) = \frac{4}{7}[/tex]
A scuba diver is 23 feet below sea level.A second diver is 7 feet closer to the surface. What integer represents the second scuba divers position relative to sea level
Answer:
The integer is -16
Step-by-step explanation:
The first scuba diver is 23 feet below sea level. THe second is 7 feet closer.
23 - 7 = 16. He is still under sea level, so it would be -16

Step-by-step explanation:
Erica went shopping for new clothes for school. She bought a pair of jeans for $45.62 and several shirts for $8.58 each. If x
represents the number of shirts she bought, which of the following equations should be used to find y, the total cost of Erica's
shopping trip?
OA. y = $8.58x + $45.62
OB. x = $45.62y + $8.58
OC. y = $45.62x + $8.58
OD. x = $8.58y + $45.62

For this test remember all questions have two answers. Please put the smaller answer in the first blank. Solve. x2=12
2.1 Solve : x2-12 = 0
Add 12 to both sides of the equation :
x2 = 12
When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get:
x = ± √ 12
Can √ 12 be simplified ?
Yes! The prime factorization of 12 is
2•2•3
To be able to remove something from under the radical, there have to be 2 instances of it (because we are taking a square i.e. second root).
√ 12 = √ 2•2•3 =
± 2 • √ 3
The equation has two real solutions
These solutions are x = 2 • ± √3 = ± 3.4641 /This is the answer

O A. 10 gallons
OB. 5 gallons
O C. 40 gallons
O D. 80 gallons
Answer:
The answer is OB 5 gallons

Its because if u divide 20 ÷ 4 you get five and there are 4 quarts in a gallon
Answer:
B. 5 gallons.
Step-by-step explanation:
if there are 4 quarts in a gallon and you have 20 quarts
20 devided by 4 = 5.
5 gallons.
Which is true?
A

Step-by-step explanation:
when you isolate the variable, the goal is to get the variable
Answer:
by itself on one side of the equal sign and value on the other
When we isolate the variable the goal is to find the value of the variable.
What are coefficients and like terms?A quantity or number that is combined with a variable is known as a coefficient. The variable is often multiplied by an integer, which is then printed next to it.
Terms that have the same variables raised to the same power are referred to as like terms. The only difference is in the numerical coefficients.
Suppose we have an equation 2x = 4.
Here, 'x' is the variable.
We isolate the variable to get the value of the variable.
2x = 4.
x = 4/2.
x = 2.
