-3x +5(x + 3) = 4 + 3x + 7(x - 6) into a simplified sentence

2 answers:

7 0

Answer:

-3x+5(x+3)=4+3x+7(x-6)

We move all terms to the left:

-3x+5(x+3)-(4+3x+7(x-6))=0

We multiply parentheses

-3x+5x-(4+3x+7(x-6))+15=0

We calculate terms in parentheses: -(4+3x+7(x-6)), so:

4+3x+7(x-6)

determiningTheFunctionDomain
3x+7(x-6)+4

We multiply parentheses

3x+7x-42+4

We add all the numbers together, and all the variables

10x-38

Back to the equation:

-(10x-38)

We add all the numbers together, and all the variables

2x-(10x-38)+15=0

We get rid of parentheses

2x-10x+38+15=0

We add all the numbers together, and all the variables

-8x+53=0

We move all terms containing x to the left, all other terms to the right

-8x=-53

x=-53/-8

Answer:

2x+15=11x-38

Step-by-step explanation:

-3x+5(x+3)=4+3x+7(x-6) (first do the parentheses)

-3x+5x+15=4+3x+7x-42 (then add the common terms)

2x+15=11x-38

A student randomly guesses on 10 true/false questions. use the binomial model to determine the probability that the student gets

lana [24]

Answer:

$P(5)=\frac{63}{256}$

Step-by-step explanation:

we are given

A student randomly guesses on 10 true/false questions

so,

$n=10$

there only true and false

so, probability getting true question is

$p=\frac{1}{2}$

so, probability getting false question is

$q=\frac{1}{2}$

the student gets 5 out of 10 questions right

so,

r=5

we can use binomial probability formula

$P(r)=\frac{n!}{r!(n-r)!} p^rq^{n-r}$

now, we can plug values

$P(5)=\frac{10!}{5!(10-5)!} (\frac{1}{2})^5(\frac{1}{2})^{10-5}$

we can simplify it

and we get

$P(5)=\frac{63}{256}$

The equation y minus 3 = negative 2 (x + 5) is written in point-slope form. What is the y-intercept of the line?

djverab [1.8K]

Answer:

y=-7

Step-by-step explanation:

y-3=-2(x+5)

distribute the -2 into the ( )

y -3= -2x -10

cancel to -2x

y- 3 = -2(0) -10

y-3 = -10

+3 +3

y= -7

Hope this helps!!

What is the prime factorization of 54?

seropon [69]

Actually none of them are the prime factors of 54.

A. indeed are factors, but neither of them are prime.
But you can break down A. into prime factors, 9 = 3*3, 6 = 3*2.
So now you have 3*3 * 3*2, which are all prime.
So the prime factorization of 54 is 3*3*3*2
