step 1: distribute “x” to “2x+1”
-you now have the equation: 2x*+1x-4x-5
step 2: combine like terms (combine “1x” and “-4x”. that gets you “-3x”.)
-you now have the equation: 2x*-3x-5
step 3: you have no more like terms, your equation is solved.

Determine whether each function is an example of exponential growth or decay. Then find the y -intercept.
y=100(0.25) x
The function y = 100 ( 0.25 ) ˣ is an exponential decay function.
An exponential function is defined as y = a ˣ where x is a variable, and a is a constant called the base of the function.
We are given a function:
y = 100 ( 0.25 ) ˣ
We need to tell whether is is a exponential growth or decay function.
We can see that the value of a ˣ = (0.25) ˣ
So, the value of a = 0.25.
Since, it is a decimal and not an integer, its value will decrease with the increase in exponent x.
So, it will be a exponential decay function.
Therefore, we get that, the function y = 100 ( 0.25 ) ˣ is an exponential decay function.

What do we mean by interest?In finance and economics, interest is the payment of an amount above the repayment of the principal sum (that is, the amount borrowed) by a borrower or deposit-taking financial institution to a lender or depositor at a specific rate by borrower or deposit-taking financial institution. It differs from a fee that the borrower may pay to the lender or a third party. It is also distinct from a dividend, which is paid by a company to its shareholders (owners) from its profit or reserve, but not at a fixed rate, but rather on a pro-rata basis as a share of the reward gained by risk-taking entrepreneurs when revenue exceeds total costs.If Jeffery originally invested $4,500.00.

Angles <6 and <12 are alternate interior angle.
What are angles <6 and <12?An interior angle is an angle that is inside a shape. It can also be described as an angle that lie in the area bounded between two parallel lines that are intersected by a transversal. In the given image, angles 6 and 11 are interior angles. The sum of interior angles is 180 degrees.
An alternate interior angle is an angle that is formed when two parallel lines are crossed by a transversal. The angle formed on the inner side of the parallel lines, and on the opposite sides of the transversal are called alternate interior angles. The alternate interior angles are angles 6 and 12.
A corresponding angle is an angle that is on the same side of one of two lines cut by a transversal and on the same side of the transversal. Angle 4 and 12 are corresponding angles.
An alternate exterior angle is the two angles that is formed the outer side of the two parallel lines but on the opposite side of the transversal. Angles 4 and 14 are alternate exterior angle.

Simplify each expression. x¹/₂ y⁻¹/₃ / x³/₄ y¹/₂
The expression can be simplified through division of the exponential (power).
In the given expression, if the powers have the same base, we can actually divide the power. In order to carry out the division of the exponential (power), we can subtract their exponential.
In the general form, a-m=1/am
As there are two different base terms x and y in the numerator and denominator, we will subtract the powers of x terms and powers of y terms.
Let us simplify the x terms,
x¹/₂÷x³/₄=x(1/2)-(3/4)
Solving the powers,(½)–(¾)=(2/4)–(¾)=(2-3)/4=-1/4
x¹/₂÷ x³/₄=x(1/2)-(3/4)= x-1/4
Let us simplify the y terms,
y⁻¹/₃÷y¹/₂= y(⁻¹/₃)-(¹/₂)
Solving the powers, (-1/3)-(1/2)=(-2/6)-(3/6)=-5/6
y⁻¹/₃÷y¹/₂= y(⁻¹/₃)-(¹/₂)=y-5/6
Putting the terms together gives us,
x-1/4 *y-5/6
It can be expressed as a fraction as a-m=1/am
x-1/4 *y-5/6=1/x1/4y5/6
Hence, x¹/₂ y⁻¹/₃ / x³/₄ y¹/₂= x-1/4 *y-5/6=1/x1/4y5/6

Write each expression as a single logarithm.
log 8-2 log 6+log 3
The expression as a single logarithm is log (2/3).
In mathematics, the inverse function of an exponent is a logarithm. This means that the logarithm of a fixed number, such as a, at base b, is used to represent the exponent to which the fixed number must be raised in order to create the number x.
The general properties of logarithm for a fixed base are:
logₐa=1logₐx+logₐy=logₐxylogₐx-logₐy=logₐ(x/y)logₐxⁿ=n logₐxlogₓy=(logₐy)/(logₐx)Now from the above properties of logarithms we can calculate:
log 8-2 log 6+log 3
=log 8 + log 3 - 2log6
We know that logₐx+logₐy=logₐxy and logₐxⁿ=n logₐx
∴log(8×3) -log(6²)
=log 24 - log 36
Again we know that logₐx-logₐy=logₐ(x/y)
=log(24/36)
=log(2/3)
Therefore the given expression written as a single logarithm is log(2/3).

The value of given expression for x=0 is 0, x=-2 is -20 and x=2 is 20.
Given the expression is (10x)⁺¹.
Firstly, we will simplify the given expression (10x)⁺¹ for x=0.
Substitute the value x=0 in given expression, we get
(10x)⁺¹=(10×0)⁺¹
As we know that something multiply to zero is 0.
So, we get
(10x)⁺¹=0
Now, we will simplify the given expression (10x)⁺¹ for x=-2.
Substitute the value x=2 in given expression, we get
(10x)⁺¹=(10×2)⁺¹
Now, we will know that if we multiply any number with 2 we get twice of it, we get
(10x)⁺¹=(20)⁺¹
(10x)⁺¹=20
Furthermore, we will simplify the given expression for x=-2.
Substitute the value x=-2 in given expression, we get
(10x)⁺¹=(10×(-2))⁺¹
Now, we will know that if we multiply any number with 2 we get twice of it, we get

The area of each card is 80.05cm^2, and the edge of each card is 8.95cm.
Priti chose a green coloured square paper of 20.5cm, since its a square the length and breadth of the card are equal
l = b
Recall the area of a square is
A = l^2
A = (20.5)^2
A= 20.5 × 20.5
A= 400.25cm^2
Since the paper is to be used for 5 cards, therefore the is divided in 5 equal cards. The are area of each card will be
A = A/5
A = 400.25/5
A = 80.05cm^2
The edge of each card is the side of the each card which can either be the length or the breadth since all the sides are equal for a square.
Recall that
A = l^2
Since the Area of each card is 80.05cm^2. Therefore,
80.05 = l^2
Finding the square root of both sides
(80.05)^1/2 = (l^2)^1/2

The value of x = -4
The given linear function is f(x) = -4x+8
We have to find the x corresponding to f(x) = 24
For our convenience, let f(x) = y
Then y = -4x + 8
This equation implies y in terms of x.
Isolating x to one side of the equation, we get,
x = (y - 8)/-4 = (8-y)/4
This equation gives x in terms of y.

In the meantime, the slope-intercept form is given by the formula y = mx + b, where m is the line's slope as well as b is the y-intercept. Given the slope m and a point on the line (x, y), we can formulate the equation using point-slope form, (y - y1) = m. (x - x1).
According to the given data:To build up the equation, use the point slope form and enter in the values.

for that reason, CGE = DGF.
also to remember : the sum of all angles around a point on one side of a line is always 180° (because they represent a half-circle with that point being the center). in other words, these angles are supplementary (together 180°).
