Answer: I think the answer is B
Step-by-step explanation:
8(x-4) = 8(1-4) = 8-32
2(4x-16) =2(4*1-16) = 8-32
8(x-4) = 8(2-4) = 16-32
2(4x-16) = 2(4*2-16) = 16-32
Answer:
B. Infinitely many solutions.
Step-by-step explanation:
8(x - 4) = 2(4x - 16)
^--This is the original equation.
If we replace x with 1...
we have the same equation, but we add an extra set of brackets. (You'll see why in a second)
8(1 - 4) = 2{4(1) - 16}
1 - 4 = -3
We start by subtracting 4 from 1. When using positive numbers, we can't do this, however. This gets us to -3. leave it in the parenthesis though!
8(-3) = 2{4(1) - 16}
4(1) = 4
Now, the reason we made an extra set of brackets is because 4x is asking you to multiply 4 by x. but as a number, you have to make an extra set of parenthesis to show that. 4 x 1 = 4 so it stays as a 4.
8(-3) = 2(4 - 16)
^-- Now, we are given this new equation. We'll move away from 8(-3) for just a second, to finish the other parenthesis. But still don't remove the parenthesis for 8(-3)!
4 - 16 = -12
We know that 4-16 would also not be possible with positive numbers, but for this equation, as said before.. you're using negative numbers. so 4 - 16 = 12
8(-3) = 2(-12)
^-- And again, we have a new equation. 8(-3) = 2(-12). Don't remove the parenthesis, as I have said before.
8(-3) = -24
Again, the equation shows with parenthesis, it wants us to multiply. Now we take 8, and multiply it by -3. This is a bit tricky, as it is with negative numbers. But in the end, you should have -24.
-24 = 2(-12)
^--The equation becomes -24 = 2(-12). We'll have to multiply again, so keep the parenthesis.
2(-12) = -24
2(-12) Is also asking you to multiply, so now we do the same as before, which again, is a bit tricky because we are using negative numbers. You should end up with -24 though.
-24 = -24
^--Now, you have -24 = -24. This is true since both are the same number.
8(x - 4) = 2(4x - 16)
^-- Here's our wonderful equation again! Let's replace X with a 2 this time!
If you don't understand, read the tips from above to understand what I'm doing in the following equations!
8(2 - 4) = 2{4(2) - 16}
2 - 4 = -2
8(-2) = 2{4(2)-16}
4(2) = 8
8(-2) = 2(8 - 16)
8 - 16 = -8
8(-2) = 2(-8)
8(-2) = -16
-16 = 2(-8)
2(-8) = -16
-16 = -16
And again, we get the same two numbers!

3 = (2x + 8)/3
Answers
Answer:
x = 1/2
Step-by-step explanation:
First you want to get rid of the fraction, so you can multiply both sides of the equation by 3.
9 = 2x + 8
Then, subtract 8 from both sides to get x by itself.
1 = 2x
Finally, divide both sides by 2 so you only have one x
1/2 = x
This means that the answer is x = 1/2.
Answer:
x=1/2 or 0.5
Step-by-step explanation:
(2x+8)/3=3
(2x+8)=3x3
(2x+8)=9
2x=9-8
2x=1
x=1/2
x=0.5

Lea invests a sum of money in a savings account with an interest rate of 3.4% compounded continuously. After 10 years, the balance is $1900. What is the amount of her initial investment?
Answers
Answer:
$1,352
Step-by-step explanation:
The computation of the initial amount is shown below:
As we know that
Ending value = Initial investment × e^{rate, time period}
$1,900 = Initial investment × e^{3.4%, 10}
$1,900 = Initial investment × e^0.34
$1,900 = Initial investment × 1.404947591
So, the initial investment is
= $1,900 ÷ 1.404947591
= $1,352

pregunta de matematica conteste verdadero o falso el siguiente enunciado : En una razón escrita como fracción el numerador recibe el nombre de antecedente y el denominador recibe el nombre de consecuente el denominador puede ser cualquier numero
Answers
Answer: falso.
Step-by-step explanation:
En una fracción, el antecedente siempre es el dividendo (también llamado numerador) y el consecuente es el divisor (también llamado denominador)
Es decir, de momento la parte de: "En una razón escrita como fracción el numerador recibe el nombre de antecedente y el denominador recibe el nombre de consecuente el denominador..."
Es verdadera.
El problema en el enunciado es:
"... el denominador puede ser cualquier número"
Esta parte es falsa, el denominador no puede ser 0.
Entonces el denominador no puede ser cualquier número, y así podemos concluir que el enunciado:
" En una razón escrita como fracción el numerador recibe el nombre de antecedente y el denominador recibe el nombre de consecuente el denominador puede ser cualquier número"
Es falso.

which equation represents the line that passes through the points (3,4) and (1,-2)
Answers
Answer:
y = 3x - 5
Step-by-step explanation:
First, you find the slope by finding the change in y and dividing that by the change in x of the two points.
-2 - 4 = -6, so -6 is the change in y.
1 - 3 = -2, so -2 is the change in x.
Then, since slope is change in y divided by change in x, you have -6/-2 = 3.
So far your equation is y = 3x + b and you're trying to find b to finish the equation.
To do this, you can pick one of the points and substitute the x and y values into the equation to find what value of b makes it true. Using (1, -2) we have
y = 3x + b --> -2 = 3(1) +b
-2 = 3 + b
b = -5
That means your equation is y = 3x - 5

Answers
Answer:
a = -15, b = -.5, c = -1
Step-by-step explanation:
1/3a = -5 --> multiply each side with 3 --> a = -15
12 - b = 12.5 --> subtract 12 from both sides --> -b = .5 --> multiply each side with -1 to get b positive --> b = -.5
.1 = -10c --> multiply each side with -10 --> c = -1
