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

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.

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:

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

Answer:

Step-by-step explanation:

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.
