Step-by-step explanation:
First we distribute the 4 amongst everything inside the parentheses.
(Remember that when we distribute numbers, we are basically multiplying them.)
So now we have: 4x - 856 = -3.7
Next we do: 856 + (-3.7), and that gives us 852.3
Finally, we divide both sides by 4 in order to isolate the x-value.
Our answer is now x = 213.075

X = 2y + 3
y = 2x + 3
What are the values for x and y?
Answer:
You should use a calculator my friend.
Answer:
x = -3; y = -3
Step-by-step explanation:
x = 2y + 3
y = 2x + 3
x = 2(2x + 3) + 3
x = 4x + 6 + 3
-3x = 9
x = -3
y = 2x + 3
y = 2(-3) + 3
y = -3
Answer: x = -3; y = -3

The first step for deriving the quadratic formula from the quadratic equation, 0 = ax2 + bx + c, is shown.
Step 1: –c = ax2 + bx
Which best explains or justifies Step 1?
subtraction property of equality
completing the square
factoring out the constant
zero property of multiplication
Answer:
Completing the square.
Step-by-step explanation:
ax2 + bx + c has "x" in it twice, which is hard to solve.
But there is a way to rearrange it so that "x" only appears once. It is called Completing the Square

Ashanti averaged 9 points per game. Write the two rates (ratios) implied by this statement. How many point
would she score if she played 14 games and maintained this average?
Answer:
Step-by-step explanation:
I can't think of many ratios, but here are two:
Ashanti sored:
(9 points)/(1 game), and
(1 game)/(9 points)
If she maintains an average of (9 points)/(1 game), after 14 games we would predict:
(9 points)/(1 game)*(14 games) = 126 points total

whats 2/3 divided by 1/4
Answer:
8/3 or 2 2/3
Step-by-step explanation:
2/3 ÷ 1/4
The numbers in 2/3 divided by 1/4 are labeled below:
2 = dividend numerator
3 = dividend denominator
1 = divisor numerator
4 = divisor denominator
To make it a fraction form answer, you multiply the dividend numerator by the divisor denominator to make a new numerator.
Furthermore, you multiply the dividend denominator by the divisor numerator to make a new denominator:
2*4/3*1=8/3
Thus, the answer to 2/3 divided by 1/4 in fraction form is:
8/3
Here we will show you how to calculate 2/3 divided by 1/4. We will give you the answer in fraction form and in decimal form.
Here is 2/3 divided by 1/4 displayed mathematically in colors:
2/3 ÷ 1/4
The numbers in 2/3 divided by 1/4 are labeled below:
2 = dividend numerator
3 = dividend denominator
1 = divisor numerator
4 = divisor denominator
To make it a fraction form answer, you multiply the dividend numerator by the divisor denominator to make a new numerator.
Furthermore, you multiply the dividend denominator by the divisor numerator to make a new denominator:
2 x 4/3 x 1= 8/3
Thus, the answer to 2/3 divided by 1/4 in fraction form is:
8/3
To make the answer to 2/3 divided by 1/4 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:
8/3 = 2.6667
The answer is rounded to the nearest four decimal points if necessary.
8/3 is an improper fraction and should be written as 2 2/3.
Fatima found a $129 prom dress at the department store. She also had to pay a 6.5% sales tax. What was the total cost of the prom dress?
Answer
137.385
Step-by-step explanation:
What is 6.5% of 129?
First, you have to change 6.5% to a decimal which is 0.065.
Then, you have to multiply 0.065 times 129 which gives you 8.385.
Finally, you have to add that amount to 129 which gives you $137.385, and that is the total cost of the prom dress

Answer:
(d) f(x) = log₆(x)
Step-by-step explanation:
If we use y in place of f(x), we see that ...
x = 6^y
Taking logs of both sides, we get ...
log(x) = y·log(6)
y = log(x)/log(6)
y = log₆(x) . . . . . . . using the change of base formula
f(x) = log₆(x)
_____
Or you can get there more directly using the relation between logs and exponentials:
