An expression dose NOT have an = sign

An equation dose have an = sign

In this case, the expression 4x+8, replace the x with 3, since x=3

                                  4x + 8

                                4 x 3 + 8         (  don't forget  PEMDAS )

                                  12  + 8

                                     20

Answer 2
So, X=8 right?
4x+8
Now, if we replace x with 8, we get 4(8) + 8. Now, the first think you do is multiply. So, 4(8) = 32. We now have 32+8, since we fixed the left part. Now, all you have to do is add 32+8, and you get 40.
Hope this helps!

I have the same question why can’t I accept this comment

All transformations that map the pattern onto itself are; a horizontal translation and a reflection across a vertical line.

What is a translation?

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s range(involving values of y) or in it’s domain(involving values of x).

All these translations have predetermined rules that we apply to the figures.

The congruence of a triangle can be obtain through Rotation; Translation; or Reflection.

Help me please, which postulate proves these two triangles are congruent?

Answers

Answer:

C

Step-by-step explanation:

These triangles do look congruent. However, in fact, we don’t have enough information. We need 3 parts of a trainable to be shown congruent for it to be congruent, including HL congruence (because this requires a right angle). In the diagram, only 2 sides are shown to be congruent. This isn’t enough information to prove that the triangles are congruent. Therefore, it is C.

what I the range of f(x)=4^x?
A. all positive real numbers
B. all real numbers
C. all real numbers grater that or equal to 4
D. all real numbers grater than 4

Answers

Answer:

We conclude that the range of the function is 'all positive real numbers'.

Thus, option (A) is true.

Step-by-step explanation:

Given the expression

[tex]f\left(x\right)=4^x[/tex]

Determining the domain:

The domain of a function is the set of input values for which the function is real and defined.

It is clear that the given function has no undefined points nor domain constraints.

Therefore, the domain is: -∞ < x < ∞

Thus,

[tex]\mathrm{Domain\:of\:}\:4^x\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:<x<\infty \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}[/tex]

Determining the range:

The range is the set of values of the dependent variable for which a function is defined.

We know that the range of an exponential function of the form

[tex]c\cdot \:n^{ax+b}+k\:\mathrm{is}\:\:f\left(x\right)>k[/tex]

[tex]k=0[/tex]

In other words, the range is all positive real numbers.

Thus,

[tex]\mathrm{Range\:of\:}4^x:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:f\left(x\right)>0\:\\ \:\mathrm{Interval\:Notation:}&\:\left(0,\:\infty \:\right)\end{bmatrix}[/tex]

Therefore, we conclude that the range of the function is 'all positive real numbers'.

Thus, option (A) is true.

Which expression is equivalent to 42 + 12? 7(6+5) 2(40+6) 6(7+2) 10(32+2)

Answers

Answer:

6(7+)

Step-by-step explanation:

1) Start by solving the original equation

42 + 12 = 54

2) Solve the other equations until you find a match

2a) Start with what's in the parenthesis

7(6+5) = 7(11) = 77

2b)

2(40+6) = 2(46) = 92

2c)

6(7+2) = 6(9) = 54

This is your answer

2d)

10(32+2) = 10(34) = 340

Answer: 6(7 +2)

Step-by-step explanation:

Calculate 42 + 12, which is 54.

Calculate 7(6 + 5), which is 7 * 11 = 77.

Calculate 2(40 + 6), which is 2 * 46 = 92.

Calculate 6(7 + 2), which is 6 * 9 = 54.

Calculate 10(32 + 2), which is 10 * 34 = 340.

And, we can conclude the expression 6(7 + 2) is equivalent to 42 + 12.

There were 120 students at a creative writing workshop last year. This year there are 138 students. What is the percent of increase in the number of students at the workshop?

Answers

Answer:

34%

Step-by-step explanation:

The percent of increase in the number of students at the workshop is 15%.

Given that, there were 120 students at a creative writing workshop last year. This year there are 138 students.

What is percentage increase formula?

The percentage increase formula is used to compare the growth in a quantity from the initial value to its final value, over a period of time. Mathematically, this formula is represented as the difference between the final value and the initial value which is divided by the initial value and then multiplied by 100.

Here, initial value = 120 students and final value = 138 students.

Difference in value = Final value - Initial value

=138-120=18

Percentage of increase = [tex]\frac{18}{120}\times 100[/tex]

= 15%

Therefore, the percent of increase in the number of students at the workshop is 15%.

Answer:

The range of [tex]f\circ g \,(x) = 2^{x+1}[/tex] is [tex]Ran\{f\circ g\,(x)\} = (0, +\infty)[/tex].

Step-by-step explanation:

Let [tex]f\circ g \,(x) = 2^{x+1}[/tex], [tex]\forall\, x \in \mathbb{R}[/tex]. The graphic represents a power function, whose lower bound is the horizontal asymptote [tex]y=0[/tex].

With a coupon, a pair of shoes that normally costs $90 is only $72. Find the COP between $90 and $72.

Answers

Answer:

The discount rate operated by the coupon is 20%.

Step-by-step explanation:

Since the pair of shoes normally sells for $ 90, but through the application of a discount coupon it sells for $ 72, to determine the discount percentage made by this coupon it is necessary to perform the following calculation:

90 = 100

72 = X

(72 x 100) / 90 = X

7,200 = 90 = X

80 = X

100 - 80 = 20

Thus, the discount operated by the coupon is 20%.

Half a bottle of lemonade is shared between 3 friends . What fraction will each child get ?

Answers

Answer:

Step-by-step explanation:

i hope this helped !!!!!!!!!

1/6 fraction of bottle of lemonade will each friend gets.

What is Fraction?

A fraction represents a part of a whole.

Given,

Half a bottle of lemonade is shared between 3 friends .

Half means 1/2.

One divided by two is half.

This half is shared between three friends.

So we need to divide half by three of friends.

1/2/(3/1)

When a fraction is divided by another fraction, the denominator is multiplied as reciprocal to numerator.

1/2×1/3

1/6

Hence, 1/6 fraction of  bottle of lemonade will each friend gets.

To find:

The missing value.

Solution:

We have,

[tex]f^{-1}(f(x))=f(f^{-1}(x))=?[/tex]       ...(i)

We know that, if [tex]f(x)[/tex] is a function and [tex]f^{-1}(x)[/tex] is its inverse function, then

[tex]f^{-1}(f(x))=f(f^{-1}(x))=x[/tex]          ...(ii)

From (i) and (ii), we get

Therefore, the missing value is [tex]x[/tex], i.e., [tex]f^{-1}(f(x))=f(f^{-1}(x))=x[/tex].

Charlie threw a ball up in the air modeled by the function f(x)=−x2+2x+4. Elizabeth release a balloon at the same time, represented by g(x)=2x. At what time do the paths cross and at what height?

Answers

Answer:

after 2 secs

Step-by-step explanation:

The paths crossed at when the height are equal i.e when f(x) = g(x)

Given

f(x)=−x^2+2x+4

g(x) = 2x

IF f(x) = g(x), then;

−x^2+2x+4 = 2x

−x^2+2x+4 - 2x = 0

−x^2+4 = 0

-x^2 = -4

x^2 = 4

x = ±√4

x = 2 and -2

Time cannot be negative

Hence x = 2

The path crossed after 2 seconds
