g(3) = 5(3) - 9
= 15 - 9 = 6
Answer : g(3) = 6
In the function [tex]g(x) =5x-9[/tex], the value of g(3) is equal to 6.
Given the following function:
[tex]g(x) =5x-9[/tex]To determine the value of g(3):
In this exercise, you're required to find the value of the given function when g of x is equal to 3.
Therefore, we would substitute the value of x into the given function.
Substituting the value of x into the function, we have:
[tex]g(x) =5x-9\\\\g(3) =5(3)-9\\\\g(3) =15-9\\\\g(3) =6[/tex]
g(3) = 6

Adrian's backyard pool contains 6.4 gallons of water. Adrian will begin filling his pool at a rate of 4.1 gallons per second. Dale's backyard pool contains 66.4 gallons of water. Dale will begin draining his pool at a rate of 0.9 gallon per second. After how many seconds will both pools contain the same amount of water?
Answer:
The data that we have is:
"Adrian's backyard pool contains 6.4 gallons of water. Adrian will begin filling his pool at a rate of 4.1 gallons per second."
Then we can write the amount of water in Adrian's pool as a linear function:
A(t) = 6.4gal + (4.1gal/s)*t
Where t is our variable and represents time in seconds.
We also know that:
"Dale's backyard pool contains 66.4 gallons of water. Dale will begin draining his pool at a rate of 0.9 gallons per second. "
We can also model this with a linear function:
D(t) = 66.4 gal + (0.9gal/s)*t
Both pools will have the same amount of water when:
D(t) = A(t)
So we can find the value of t:
6.4gal + (4.1gal/s)*t = 66.4 gal + (0.9gal/s)*t
(4.1gal/s)*t - (0.9gal/s)*t = 66.4gal - 6.4gal
(3.2gal/s)*t = 60gal
t = 60gal/(3.2gal/s) = 18.75s
In 18.75 seconds both pools will have the same amount of water.

A large male giraffe needs to eat at least 75 pounds of food each day. At each feeding, the giraffe is fed 3 pounds of food. The giraffe has already consumed 24 pounds of food. How many more times x does the giraffe need to be fed? Write your answer as an inequality
Answer:
How many more times x does the giraffe need to be fed?
a) 17 times
Write your answer as an inequality
Let x represent the number of feedings left.
1/3(75 - 24) ≤ x
= (25 - 8) ≤ x
= 17 ≤ x
Step-by-step explanation:
A large male giraffe needs to eat at least 75 pounds of food each day.
At each feeding, the giraffe is fed 3 pounds of food.
Hence,
3 pounds of food = 1 feeding
75 pounds of food =
= 75/3
= 25 feedings.
That means in a day, the giraffe is fed 25 times.
The giraffe has already consumed 24 pounds of food. How many more times x does the giraffe need to be fed?
3pounds of food = 1 feeding
24 pounds of food =
Cross Multiply
= 24/3
= 8 feedings.
From the calculation here, the cloth has already fed the giraffe 8 times
Hence,
= 25feedings - 8 feedings
= 17 Feedings left.
Hence, the giraffe has 17 Feedings left to go.
Write your answer as an inequality
Let x represent the number of feedings left.
1/3(75 - 24) ≤ x
= (25 - 8) ≤ x
= 17 ≤ x

========================================
Work Shown:
Use law of cosines to find angle B
b^2 = a^2 + c^2 - 2*a*c*cos(B)
9^2 = 6^2 + 12^2 - 2*6*12*cos(B)
81 = 36 + 144 - 144*cos(B)
81 = 180 - 144*cos(B)
81 - 180 = -144*cos(B)
-99 = -144*cos(B)
-144*cos(B) = -99
cos(B) = (-99)/(-144)
cos(B) = 0.6875
B = arccos(0.6875)
B = 46.5674634422102
B = 47 when rounding to the nearest whole number

What is the closest perfect square greater than 54
Answer:
64
Step-by-step explanation:
Perfect squares are integers multiplied by themselves.
2 times 2 = 43 times 3 = 94 times 4 = 15The closest perfect squares to 54 are 49 (7^2) and 64 (8^2).
49 is less than 54, so that's ruled out.
Therefore, the closest perfect square to 54 that is greater than it is 64.

Step-by-step explanation:
they have to have the same slope to be parallel
Answer:
[tex]m = -3[/tex]
Step-by-step explanation:
-To determine the slope of the red line on the graph, you need the slope formula:
[tex]m = \frac{y_{2} - y_{1}}{x_{2}- x_{1}}[/tex]
-Since the red line shows it's decreasing, then the number will be negative. So, l picked [tex](0,3)[/tex] and [tex](1,0)[/tex] for the slope formula:
[tex]m = \frac{0 - 3}{1 - 0}[/tex]
Then, solve:
[tex]m = \frac{0 - 3}{1 - 0}[/tex]
[tex]m = \frac{-3}{1}[/tex]
[tex]m = -3[/tex]
so, the slope is [tex]-3[/tex].

John is going to start saving $20 every month to buy a new IPod. His parents gave him $10 for his birthday to open his savings account. The equation y = 20x + 10 represents John’s savings account balance x months after be began saving.
a) How many months will it take John to save enough money for the $300 IPod? Explain.
b) If John saved $40 per month instead of $20, how would you expect the slope of the graph to change? Explain.
Answer A: It would take fifteen months, or one year and three months, to get three hundred dollars.
Answer B: It would take seven and a half months to get three hundred dollars at this rate. It would also change the slope by making it go down more.
Step-by-step explanation:
Three hundred divided by twenty equals fifteen, which represents the amount of months.
If you do the same thing with the other ratio, but change twenty to forty, you get seven and a half.
Have a nice day!
a) The number of months for the saving of $300 will be 14¹/₂.
b) The slope of the saving of $40 will be y = 40 x + 10
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that John is going to start saving $20 every month to buy a new iPod. His parents gave him $10 for his birthday to open his savings account. The equation y = 20x + 10 represents John’s savings account balance x months after he began saving.
Part (a),
The number of the months will be calculated as,
y = 20x + 10
300 = ( 20 x + 10 )
290 = 20x
x = 14¹/₂ months
Part(b),
The slope will be 40 for the saving of $40.

Answer:
B
Step-by-step explanation:
the area of a triangle is
[tex]A=\frac{1}{2}(h)(b)[/tex]
so if we take as
[tex]from\:(x_1,y_1)\rightarrow(x_2,y_1)[/tex]
so the base is
[tex]b=x_2-x_1[/tex]
so the height is
[tex]from\:b\rightarrow(0,0)[/tex]
the distance is
[tex]h=y_1-0[/tex]
so the area is
[tex]A=\frac{1}{2}(y_1+0)(x_2-x_1)\\\\=\frac{1}{2}(y_1)(x_2-x_1)[/tex]
so the answer is B
The average distance of the sun from Earth is about 1.5 x 108 kilometers.
If the thickness of a quarter is 1.5 millimeter, how many quarters do
you need to stack to reach the sun? A kilometer is equal to a million
millimeters.
a. 102 million
c. 104 billion
b. 105 billion
d. 106 billion
Answer:
10⁵ billion
Step-by-step explanation:
given that distance from sun to earth
= 1.5 x 10⁸ km (we need to convert this to millimeters)
= 1.5 x 10⁸ km x 1 million mm per km
= 1.5 x 10⁸ km x 1,000,000 mm/km
= 1.5 x 10⁸ km x 10⁶ mm/km
= 1.5 x 10⁸ x 10⁶
= 1.5 x 10⁽⁸ ⁺ ⁶⁾
= 1.5 x 10¹⁴ mm
also given that a quarter is 1.5mm thick, hence the number of quarters that will span the distance between the sun an earth (i.e 1.5 x 10¹⁴ mm)
= 1.5 x 10¹⁴ mm ÷ 1.5 mm/quarter
= 10¹⁴
= 100,000,000,000,000 (remember that a billion has 9 zeros)
= 100,000 billion
= 10⁵ billion

Answer:
x int (4,0)
y int (0, -6)
Step-by-step explanation:
Answer:
(4, -6)
Step-by-step explanation:
To solve for the x-intercept, plug in 0 for y. To solve for the y-intercept, plug in 0 for x. You do this because the x-intercept is the point at which the line intercepts the x-axis, meaning y would equal 0, and the y-intercept is the point at which the line intercepts the y-axis, meaning x would equal 0.
