What is the value of f(-5) in the function f(x)=6x-3?

Answers

F(-5)=6x-3

F(-5)=6(-5)-3

F(-5)=-30-3

= +33
When asking for f(-5) or any other number, they are asking you to plug in that number for x.

So, f(-5) = 6(-5) - 3
f(-5) = -30 - 3
f(-5) = -33

Find the length of BC

Answers

Answer:

pasagot po tnx
I will mark you as brainliest if your answer is good :3​

Answers

Answer:

416.50 pesos

Step-by-step explanation:

Given

Represent the bread with b.

Mayonnaise with m

Ham with h

[tex]Amount\ Paid = 1000[/tex]

Required

Determine the change

From the question: a loaf costs 22.50

This is represented as:

[tex]b = 22.50[/tex]

5 loaves will be:

[tex]5*b = 22.50*5[/tex]

[tex]5b = 112.50[/tex]

A bottle of Mayonnaise costs 55.50

This is represented as:

[tex]m = 55.50[/tex]

2 bottles will be:

[tex]2*m = 55.50*2[/tex]

[tex]2m = 111[/tex]

Lastly,

1kg of ham costs 240

This is represented as:

[tex]h =240[/tex]

1.5kg will be:

[tex]1.5*h =240*1.5[/tex]

[tex]1.5h =360[/tex]

The cost of the items is:

[tex]Costs = 5b + 2m + 1.5h[/tex]

This gives:

[tex]Costs = 112.50 + 111 + 360[/tex]

[tex]Costs =583.50[/tex]

Her change is calculated as:

[tex]Change = Amount\ Paid- Cost[/tex]

[tex]Change = 1000 - 583.50[/tex]

[tex]Change = 416.50[/tex]
