Answer: X = 9
Step-by-step explanation:
First insert the function into a graphing calculator.
We are trying to find the x intercepts, we substitute y=0.
With a graphing calculator look at where the line intercepts the x axis, (9,0) , and we find that x=9.
What is the equation of the line that passes through the points (4, 15) and (0, 3)?
Answer:
Y=3x+3
Step-by-step explanation:
Gradient = :[tex]\frac{y2-y1}{x2-x1}[/tex] = :[tex]\frac{3-15}{0-4}[/tex] = :[tex]\frac{-12}{-4}[/tex] = 3
Y= mx + c
y = 3x + c
Insert x and y values for first point(4,15)
15 = 3 (4) + c
15 = 12 + c
3 = c
Y=3x +3
Answer:
The equation of the line is y=3x+3
Step-by-step explanation:
y=mx+b is the y intercept form of the equation of this line.
m=slope, and we find the slope by the equation m=y2-y1/x2-x1. Plugging our number into that formula, we get m=3 - 15/ 0 - 4, or -12/-4, which simplifies to 3.
Now we can add our slope into the formula.
y=3x+b
Next, we solve for the y intercept, or b. You can use whatever point to get the answer, but I will use 4 ,15).
y=mx+b is the equation, or substituting the numbers, gets you 15=3×4+b. now solve for b: b=15-(3)(4). b=3.
now, with slope and y intercept plugged in, the final equation is. y=3x+3
5/3y=-(x-5) the slope intercept
Answer:
y = - [tex]\frac{3}{5}[/tex] x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
[tex]\frac{5}{3}[/tex] y = - (x - 5) ← distribute parenthesis
[tex]\frac{5}{3}[/tex] y = - x + 5 ( multiply through by 3 to clear the fraction )
5y = - 3x + 15 ( divide terms by 5 )
y = - [tex]\frac{3}{5}[/tex] x + 3 ← in slope- intercept form

“Devon is having difficulty determining if the relation given in an input-output table is a function.
Marco explains to him that in order to tell if the relation in the table is a function, Devon needs to check if any output values are reported. If they repeat and have different input values, the relation is not a function.

If three dice are rolled, what chance is there
of throwing a total of 3?
Answer:
Just as one die has six outcomes and two dice have 62 = 36 outcomes, the probability experiment of rolling three dice has 63 = 216 outcomes. This idea generalizes further for more dice. If we roll n dice then there are 6n outcomes.
We can also consider the possible sums from rolling several dice. The smallest possible sum occurs when all of the dice are the smallest, or one each. This gives a sum of three when we are rolling three dice. The greatest number on a die is six, which means that the greatest possible sum occurs when all three dice are sixes. The sum of this situation is 18.
When n dice are rolled, the least possible sum is n and the greatest possible sum is 6n.
There is one possible way three dice can total 3

Answer:
[tex]112\pi[/tex]
Step-by-step explanation:
hi! for this problem, all we need is the equation for the SA for a cylinder!
here's the equation: [tex]A=2\pi(r)(h)+2(\pi)r^{2}[/tex]
BUT FIRST let's identify our given numbers
the radius, or r, is 4 (r = 4) the height, or h, is 10 (h = 10)now all we have to do is plug in what is given to the equation above! not so bad, right?
plugged in equation
[tex]A = 2\pi (4)(10) + 2\pi (4)^{2}[/tex]
- now let's simplify!
[tex]2\pi (40) + 2\pi (16)[/tex]
[tex]80\pi + 32\pi[/tex]
[tex]112\pi[/tex]
your answer should be [tex]112\pi[/tex]

Please someone help me with these! Mark brainliest !
Answer:
4.) Cost of cordless phone = $55
cost of each additional handset = $25
Therefore, the overall cost of the cordless phone, including the 3 extra handsets is:
$55 + 3($25) = $55 + $75 = $130
5.) Given the function, f(d ) = .20d + 14, where:
f(d) = global temperature (in Celsius)
d = number of decades
To evaluate the value of f (d ) at f(10), you'll have to substitute the value of d = 10 as input into the function:
f(10) = .20(10) + 14
f(10) = 2 + 14
f(10) = 16
6.) Value of f(10):
In 10 decades, the predicted global temperature will be 16° Celsius.
7.) The correct answer is B. The global temperature f(d) depends on the number of decades, d.
Explanation: the independent variable is d → it is the input of the function. The output primarily depends on the given value of input.
8.) Given the function, f(t ) = 0.2t
where t = represents number of days elapsed since the planting of the seed.
Evaluate f(40):
f(40) = 0.2(40)
f(40) = 8
Context of f(40): The value of the function, f(40) = 8 represents the 8 centimeter height of the habanero plant after 40 days of planting its seeds.

Franklin starting playing video games as soon as he got home from school. He played video
games for 54 minutes. Then Franklin helped clean the kitchen for 1 hour. After the kitchen
was clean, it took Franklin 57 minutes to finish his homework. wWhen Franklin finished his
homework, it was 5:56 P.M. What time did Franklin get home from school?
Answer:
3:05
Step-by-step explanation:
Answer: he got home at 3:05 pm!
Step-by-step explanation:
working backwards from the time stamp 5:56pm, we can just subtract the time he spent gaming and doing chores:
5:56
-0:54 mins games
-1:00 cleaning
-0:57 for homework= the time he got home, but lets make it easier!
54+57=111, in total, that's 1:51 time wise, so that simplifies it a little, be we can simplify it further, by adding the hour spent cleaning.
1:51 on homework n games + 1:00 on cleaning = 2:51 spent on home stuff in general
so lets go back to our subtraction:
5:56 pm -time stamp after all his chores
-2:51 spent on home stuff
= 3:05 pm the time he left school

The composite function G(F(x)) = 4√x is for the functions when F(x) = √x and G(x) = 4x.
What is Composition of Functions?Composition of two functions f and g can be defined as the operation of composition such that we get a third function h where h(x) = (f o g) (x).
h(x) is called the composite function.
Given that, the composite function is,
G(F(x)) = 4√x
We have to find the functions G(X) and F(x).
We know that,
G(F(x)) is the function G(x) when x is changed to F(x).
Let G(x) = 4x
In G(F(x)), x will be replaced by F(x).
In order to get 4√x, x is replaced by √x.
So, F(x) = √x
Hence G(x) = 4x and F(x) = √x.

Which is the equation of the line, in point-slope form, that has a slope of 2 and
passes through the point (4, -7)?
y+7= 2(x-4)
y-7 = 2(x+4)
x-7 = 2(x-4)
y-4 = 2(x+7)
Answer: y+7 = 2(x-4)
Step-by-step explanation: Point slope form is y − y1 = m(x − x1), where m is the slope and (x1,y1) is one known point on the line. We are told that m= 2 and (4,-7). Therefore:
(y − (-7)) = 2(x − (4))
y+7 = 2(x-4)
