What is f(4) for the function f(x) = 6x +3?
f(4)=0
The value of function f(4) is 27.
It is required to find the value of function f(4).
What is function?
A function is defined as a relation between a set of inputs having one output each. function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.
Given that:
The function is
f(x) = 6x +3
Now put the value x=4 in the given function, we get
f(4)=6(4) +3
= 24+3
=27
f(4)=27.
Hence, the value of function f(4) is 27.

Isaiah is mowing lawns for a summer job for every mountain Charlie charges an initial fee of $10 plus $6 dollars for each additional hour
1. write an equation in slope intercept form
2. how much money does he make after working one job for four hours
Answer:
y = 6x + 10
Isaiah makes $34.00 after working for 4 hours.
Step-by-step explanation:
Slope intercept form is y=mx+b
In this situation the equation would look like so, x = amount of hours:
y = 6x + 10
To solve for how much Isaiah earns after 4 hours plug in 4 instead of x.
y = 6(4) + 10
y = 24 + 10
y = 34
Isaiah makes $34.00 after working for 4 hours.
Hope that helps and have a great day!
14) zeroes of the polynomial x^2+5x+6 are...
Both positive
Both negative
One is positive and other is negative
None
Answer:
both negative
Step-by-step explanation:
Descartes rule of signs tells us how many positive and negative real roots a polynomial has.
Given
f(x) = x² + 5x + 6 , with signs
+, +, + ← no change of signs, thus no positive zeros
f(- x) = (- x)² + 5(- x) + 6 = x² - 5x + 6 , with signs
+, -, + ← with 2 changes of signs. thus 2 negative zeros
Answer:
B) Both Negative
Step-by-step explanation:
[tex](x^2+5x+6)\\=(x^2+2x+3x+6)\\=x(x+2) + 3(x+2)\\=(x+3)(x+2)\\Hence,\ as\ their\ factors\ are\ (x+3)\ and\ (x+2)\ their\ zeroes\ are\ (-3)\ and\ (-2)\ respectively..\\As\ they\ both\ are\ negative..\ the\ answer\ is\ b)\\\[/tex]
what's y intercept on a graph of y = -5x + 6
The y-intercept on a graph of y = -5x + 6 is 6.
What are intercepts?The points where a line crosses an axis are known as the x-intercept and the y-intercept, respectively.
We have a linear equation,
y = -5x + 6.
The general slope-intercept form,
y = mx + b.
Where m is the slope and b is the y-intercept.
Comparing,
b = 6.
Therefore, 6 is the y-intercept.

1. Which equation represents a line that passes through the point (-2,6) and is parallel to the line whose equation is 8x – 4y = 6?
Answer:
y=2x+10
Step-by-step explanation:
First, let's put the equation into slope-intercept form. We get y=2x-3/2.
Parallel lines have the same slope, so the slope of the line will be 2.
We then substitute the point into the equation to find the y-intercept.
We get y=2x+10

Devaughn is 13 years younger than Sydney. The sum of their ages is 79 . What is Sydney's age?
Answer: 46 years old
Step-by-step explanation: If Devaughn is 13 years younger than Sydney,
we can represent Sydney's age as x and Devaughn's age as x - 13.
Since the sum of their ages is 79, we have x + x - 13 = 79.
This simplifies to 2x = 92.
Dividing both sides by 2, we have x = 46.
So sydney is 46 years old.

Mr. Richard plans to take 25 students on a school trip. They plan to go to Zoo. The bus fee is $100 for the entire trip. Entrance fee is $2.50 per person. How much should each student pay? Note: Mr. Richard does not need to pay.
Answer:
$162.50
Step-by-step explanation:
+$100
25x2.50= $62.50
+$62.50
100+62.50=162.50
Answer:
Each student should pay $6.50
Step-by-step explanation:
The question is not very clear.
If Mr. Richard has to pay to enter:
Total cost = $100 + ($2.50×26) = $165
Cost per student = [tex]\frac{165}{25}[/tex] = $6.60
Each student should pay $6.60
If Mr. Richard doesn't have to pay to enter:
Total cost = $100 + ($2.50×25) = $162.5
Cost per student = [tex]\frac{162.5}{25}[/tex] = $6.50
Each student should pay $6.50

Step-by-step explanation:
The gas tank in Daniel's car has a capacity of 19.1 gallons.
On a trip to see his best friend Daniel begins with 12.8 gallons of gas in the tank.
He stops after driving for 2 hours and fills the tank to capacity with 14.4 gallons.
When Daniel arrives at his friend's house, he has 3.7 gallons of gas left.
Total amount of gas filled was (12.8 + 14.4) = 27.2 gallons.
The amount of gas remaining after the trip was 3.7 gallons
The amount of gas, in gallons, used by Daniel on his trip was 27.2 - 3.7 = 23.5 gallons

Answer:
x=60
Step-by-step explanation:
Answer: The equation 60 + x= 3x -70 could be set up to solve for x.
Step-by-step explanation:
The two remote interior angles sums will equal to the exterior angle .
Meaning that angle 60 plus angle x has to equal to angle 3x -70.
60 + x= 3x -70 Now solve for x by adding 70 to both sides
+70 +70
130 + x = 3x Now subtract x from both sides
-x -x
130 = 2x Divide both sides by
