Answer:

Part A: So the solution for 4 = 2x-1 is -2. Why they're intersecting is because x is -0.5 in both cases. 2/4, as we already know, is 0.5. Since, this -2/4, we can just make 0.5 negative, so -0.5. -0.5 times 4 = -2, so x is -0.5. For y = 2x-1, multiply -0.5 by 2, which would get you -1. Then after that subtract 1, for -2.

Part B:

Well, notice how none of the entries for y = 4x and y = 2x-1 match. That would mean the answer wouldn't be an integer. (Attachment is the table)

Part C:

First, graph both y = 4x and y = 2x-1. After that, find where the two equations' y-coordinates are the same (So, on a graph, where they intersect.). The y-coordinate in common is your answer.

Answer:

A: the intersection represents the answer because the place where it intersects is where the equations have the same x values.

B:  they intersect at the point (0,1)

C: plot the equations on an online graph and solve, Its almost impossible to draw an accurate continuing graph for an exponential equation. I recommend desmos.

Answer:

5b - 3

Step-by-step explanation:

5b-3 is the algebraic expression for "3 less than the product of 5 and b"

Expression is a combination of variables, numbers and Operators.

The given sentence is

"3 less than the product of 5 and b"

Let us write the sentence in algebraic form.

We know that product of 5 and b means multiplication of 5 and b that means five times of b.

3 less than means subtracting 3 from another number.

So 3 less than the product of 5 and b is 5b-3.

Hence 5b-3 is the algebraic expression for "3 less than the product of 5 and b"

Answer:

You treat it as 10^4 (the small number is the number of zeros. Therefore the answer is 10000. Or of you meant 10^-4. Its the same concept, just reversed. So the answer in this case is 0.0004.

10 to the power of 4 is equal to 10,000.

To calculate 10 to the power of 4 as a decimal, you need to raise the base number (10) to the exponent (4).

Here are the steps to compute it:

Step 1: Start with the base number, which is 10.

Step 2: Multiply the base number (10) by itself 4 times, since the exponent is 4. The calculation looks like this:

10 x 10 x 10 x 10 = 10,000

Step 3: The result of multiplying 10 by itself 4 times is 10,000.

So, 10 to the power of 4 (10⁴) is equal to 10,000.

Hence 10 to the power of 4 is equal to 10,000.

Answer:

B. Baseball cap

Step-by-step explanation:

Given that:

Total money available with Annabeth = $29.00

Amount at which T-shirt was bought = $15.32

Things that Annabeth wants to buy:

Soccer ball for the price of $12.87 or

Baseball cap for the price of $8.39 or

Set of shin guards for the price of $14.98 or

Water bottle for the price of $5.93

The equation that can be used to find the cost of most expensive item with the remaining amount of money:

$15.32 + [tex]c[/tex] = $29.00

[tex]\Rightarrow c = 29 - 15.32\\\Rightarrow c= \$13.68[/tex]

Cost of items that can be bought in the decreasing order is:

Cost of pair of shin guards ( $14.98 ) > Cost of soccer ball ( $12.87 ) > Cost of baseball cap ($8.39) > Cost of water bottle ( $5.93 )

The most expensive item that can be bought is the Soccer ball at $12.87.

Answer is:

B. Soccer ball

Cost of shin guards is more than the amount of money remaining.

Answer:

domain: (-∞ , ∞)

range: (-∞, 2]

Step-by-step explanation:

the domain is the set of values of what the x value can be. This function is parabolic and upside down, it can have a range of x values from - infinity to positive infinity. The function is most likely y=-x^2 +2

range is the output (y values) the function can possibly have. the max is 2 and includes 2 so we use bracket for that. The smallest y value can reach towards negative infinity.

Answer:

-15%

Step-by-step explanation:

percentage change is calculated by

(new price - old price) / old price

(850 - 1000) / 1000

please give thanks by hitting heart button! :)

Answer:

15%

Step-by-step explanation:

1. Subtract the sale price from the normal price.

$1000 - $850 = $150.

2. Divide this amount by the original price.

$150/$1000 = 0.15

3. Multiply by 100 to get the %.

0.15 x 100 = 15%

Step-by-step explanation:

x is horizontal, along the bottom of the graph and the line goes through at the 6th line.

Step-by-step explanation:

The formula of a circumference of a circle with radius r:

[tex]C=2\pi r[/tex]

Solve for r:

[tex]2\pi r=C[/tex]     subtitute  [tex]\pi\approx\dfrac{22}{7}[/tex]

[tex]2\cdot\dfrac{22}{7}r=C[/tex]

[tex]\dfrac{44}{7}r=C[/tex]       multiply both sides by 7

[tex]44r=7C[/tex]      divide both sides by 44

[tex]r=\dfrac{7C}{44}[/tex]

Substitute the values of the circumference from your question:

[tex]i.\ C=88cm\\\\r=\dfrac{7\cdot88}{44}=\dfrac{7\cdot2}{1}=12(cm)\\\\=================[/tex]

[tex]ii.\ C=1.4m\\\\r=\dfrac{7\cdot1.4}{44}=\dfrac{9.8}{44}=\dfrac{98}{440}=\dfrac{49}{220}(m)\\\\====================[/tex]

Answer:

A = 60 degrees

C = 8 m

Step-by-step explanation:

Whenever we are faced with a geometry problem, and we have a right-angled triangle within the problem, we are to remember Pythagoras' Law first, and the fact that a right-angled triangle always has an angle that measures 90 degrees.

We will also need to know that the sum of the angles in a triangle is 180 degrees.

Therefore, angle A will be = 180 - (90 +30) = 60 degrees

From Pythagoras' Law, we can see that [tex]c= tan 30 \times 8\sqrt{3} =8[/tex]

therefore, line c = 8m

Answer:

{0, 3.75, 7.5, 11.25, 15, 18.75, 22.5}

Step-by-step explanation:

Since the values in this function cannot go on infinitely this is a discrete funciton.

Its basically asking how much he can spend on drinks with 23$ if they are each 3.75$, this means that he can buy at most 6 drinks. Imagine a disctrete graph with a point on every value he spends per drink, (0,0) (1 , 3.75) (2 , 7.5) etc.

As our bright fellow shadow188 has stated, y is the range or the output so you list the possible outputs for the range in bracets.

I hope you found this helpful, ik its a little late.

The required range will be $3.75 ≤ y ≤ $23 for the function.

Given that,
Brandy only has $23 in cash to spend on drinks, and the concession stand charges $3.75 for a drink.
x represents the number of drinks purchased, and y is the amount of money spent on drinks, what is the range in this situation is to be determined.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
Let the x be the cost of the drink and y be the total amount of money spent,
Since there are concession stand charges of $3.75 also.
So the minimum charge will be $3.75 whether bought the drink or not, and Brandy has $23 to spend on drinks so the maximum will be $23.
So, the range can be given as $3.75 ≤ y ≤ $23.

Thus, the required range will be $3.75 ≤ y ≤ $23 for the function.
