Answer:

40 matches

Step-by-step explanation:

Let x represent the amount of matches she has in total then...

x-5=75

Add 5 to both sides

Answer:

number of apples purchased to the cost of apples

Step-by-step explanation

The only relation that is a function is number of apples purchased to the cost of the apples.

A relation is considered a function if each input (domain element) is associated with exactly one output (range element). Let's analyze the given relations:

City name to state name: This is not necessarily a function. Multiple cities can be in the same state.

Number of apples purchased to the cost of the apples: This is a function. Each number of apples purchased is associated with a single cost of apples.

Days of the week to the months of the year: This is not a function. Some days of the week might correspond to multiple months.

Last name to phone number: This is not necessarily a function. Different people with the same last name could have different phone numbers.

Answer:

0-7+ (19 + 5) = (-7 + 19) + 5

Step-by-step explanation

The associative property of addition states that how number of groups won't change the answer.

EX: 2 + (2 + 3) = (2 + 2) +3

In this example, both answers are equal to 7.

In the given problem, '0-7+ (19 + 5) = (-7 + 19) + 5' is the best choice because the order of the parenthesis is being changed, yet the answer is still the same.

Equal expressions can be taken as equal to some third quantity (which is not used previously, and is new). The equations for given equation to graph are:  and  

When you raise a number with an exponent, there comes a result.

Lets say you get

[tex]a^b = c[/tex]

Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows

[tex]b = \log_a(c)[/tex]

Log with base 10 is written as [tex]\log(x)[/tex] mostly.

For the given equation, using the above definition, we get:

[tex]log(x+1) = -x^2 + 10\\\\\\(x+1) = 10^{-x^2 + 10}\\x + 1 = 10^(-x^2} \times 10^10 = y\: \: \rm (say)\\[/tex]

Then we get two equations as:

[tex]y = x + 1\\y = 10^(-x^2} \times 10^10[/tex]

Graphing those equations and then getting their common intersection point will give us the solution, as plotted below in the attached graph.

These are the two equations that should be graphed.

Answer:

The domain is the set of x values for which the function resides in.

In this graph, it is unclear as to if the function goes on to infinity, but if it does, the answer is quite easily:

(-2, 4] and [7, ∞)

since the function starts on the left at -2 then continues to the right, with a pause, then indefinitely after.

Answer:

f = 9.25 (I think but maybe I read f(4) wrong)

Step-by-step explanation:

so f(4) means x = 4.

The new equation is

f(4) = 2x4 ^2 - 4 + 9
you first do 2x4^2. The minus 4. The add 9.
the answer to that is 4f = 37

Then solve

The total monthly income of Delisile including her spendings is R 1,520,000

Given:

= 0.30x

Amount remaining = x - 0.30x

= 0.70x

Amount spent on food and traveling = 50% of 0.70x

= 0.50 × 0.70x

= 0.35x

Total = rent + food + education + amount left

x = 0.30x + 0.35x + 220,000 + 312,000

x = 0.65x + 532,000

x - 0.65x = 532,000

0.35x = 532,000

x = R 1,520,000

Answer:

4.95 and 2.25

Step-by-step explanation:

x+y=7.2

x-y=2.7

Add equations

x+y + x-y= (2x-y+y)=2x

7.2+2.7=9.9

Therefore 2x=9.9 x=9.9/2=4.95

x=4.95

x+y=7.2

4.95+y=7.2

y=7.2-4.95=2.25

y=2.25

Answer:

4.95 and 2.25.

Step-by-step explanation: This is really long... (PLEASE TAKE NOTE THE INFO ISNT DIRECTLY WRITTEN BY ME).

Adding equations (1) and (2), we get

Therefore

x=4.95

Substituting value of x from (3) in (1), we get

y=2.25

From (3) and (4), the two numbers are 4.95 and 2.25.
