Solve the equation: .2x(.7x-5)+0.2=1.4(x-1.6)
9514 1404 393
Answer:
x = 8/7
Step-by-step explanation:
.2(.7x-5)+0.2=1.4(x-1.6) . . . . given
Eliminating parentheses, we have ...
0.14x -1 +0.2 = 1.4x -2.24
1.44 = 1.26x . . . . . . . add 2.24-0.14x to both sides
x = 1.44/1.26 . . . . . . divide by the coefficient of x
x = 8/7 . . . . . . . . . . .simplify the fraction
__
As a repeating decimal, the value of x is ...
[tex]x=1.\overline{142857}[/tex]
However, the notation 1.(142857) is usually reserved for the case where the contents of parentheses are being multiplied by the factor in front. You would need to consult your instructions to see how the decimal version of the answer should be entered. (Quite often, rounding is suggested.)

Answer:
[tex]\frac{x^5+y^5}{x+y}=x^4-x^3y+x^2y^2-xy^3+y^4[/tex]
Step-by-step explanation:
Given the expression
[tex]\left(x^5+y^5\right)\div \left(x+y\right)[/tex]
[tex]\mathrm{Apply\:factoring\:rule:\:}x^n+y^n=\left(x+y\right)\left(x^{n-1}-x^{n-2}y+\:\dots \:-\:xy^{n-2}\:+\:y^{n-1}\right)\:\quad \quad \mathrm{n\:is\:odd}[/tex]
[tex]x^5+y^5=\left(x+y\right)\left(x^4-x^3y+x^2y^2-xy^3+y^4\right)[/tex]
[tex]=\frac{\left(x+y\right)\left(x^4-x^3y+x^2y^2-xy^3+y^4\right)}{x+y}[/tex]
Cancel the common factor: x+y
[tex]=x^4-x^3y+x^2y^2-xy^3+y^4[/tex]
Thus,
[tex]\frac{x^5+y^5}{x+y}=x^4-x^3y+x^2y^2-xy^3+y^4[/tex]

to positive infinity.
values are equal to zero
values go to positive infinity.
The answer is the last choice.
When x approaches positive infinity, the value of f(x) will also approach positive infinity too.
Notice how we substitute x in the equation with any positive numbers and we will get high f(x) value as the sign of positive infinity approach when x approaches positive infinity.

What are the coordinates of the point 4/5
of the way from A to B?
Answer:
D
Step-by-step explanation:
The coordinates of the point at a ratio of 4/5 for the line AB will be (4,4). The correct option is D.
What is coordinate geometry?
A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
Given that the line AB on the coordinate system is having a ratio of 4/5.
From the given data it is observed that the line AB is distributed in the fraction of 4:5. The point on this fraction has the coordinates ( 4,4).
Therefore, the coordinates of the point at a ratio of 4/5 for the line AB will be (4,4). The correct option is D.

An account with an initial deposit of $6,500 earns 7.25% annual interest, compounded
continuously. How much will the account be worth after 20 years
Answer:
$27,710.24
Step-by-step explanation:
You want to know the value of $6500 earning 7.25% interest compounded continuously for 20 years.
Continuous compoundingThe formula for the amount in an account earning interest at rate r compounded continuously is ...
A = P·e^(rt)
where P is the principal invested at rate r for t years.
Your amount is ...
A = $6500·e^(0.0725·20) = $6500·e^1.45 ≈ $27,710.24
The account will be worth about $27,710.24 after 20 years.

Answer:
y = (4/3)x.
or in standard form it is
-4x + 3y = 0.
Step-by-step explanation:
The slope m = (8-4) / (6-3)
= 4/3
Using the point-slope form of a line:
y - y1 = m(x - x1)
We use m = 4/3, x1 = 3 and y1 = 4:
y - 4 = 4/3(x - 3)
Multiply through by 3:
3y - 12 = 4(x - 3)
3y = 4x - 12 + 12
3y = 4x
y = (4/3) x
or in standard form it is
-4x + 3y = 0.
