The value of the linear function at x = 4 will be 14.
What is a function?A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.
The function is given below.
f(x) = 3x + 2
The degree of the function is one. Then the function is a linear function.
The value of the function at x = 4 will be given as,
f(4) = 3(4) + 2

Extraneous solutions and multiple answers/rootsStep-by-step explanation:
Step 1: Define
-x² = -36
Step 2: Solve for x
Divide -1 on both sides: x² = 36Square root both sides: x = ±6Step 3: Check
Plug in x to verify it's a solution.
Substitute in -6: -(-6)² = -36Exponents: -(36) = -36Multiply: -36 = -36Substitute in 6: -(6)² = -36Exponents: -(36) = -36Multiply: -36 = -36Here we see that both -6 and 6 do indeed work as solutions.

How do you solve -7x – 13 ≥ 8 ?
Answer:
x ≥ - 3
Step-by-step explanation:
Step 1:
- 7x - 13 ≥ 8 Equation
Step 2:
- 7x ≥ 21 Add 13 on both sides
Step 3:
x ≥ 21 ÷ - 7 Divide
Answer:
x ≥ - 3
Hope This Helps :)
Answer: x≤−3
Step-by-step explanation:
So first you -7*x-13-(8)≥0
then you are supposed to pull out like the factors -7x - 21 = -7 • (x + 3)
then you divide both sides by -7 then you flip the inequality sign remember that :). then subtract 3 from both sides. and then you got x ≤ -3 So I really hoped this helped :)

Answer:
y = 2x + 5
Step-by-step explanation:
In order to write this equation (in slope-intercept form), you need to find the slope (m) and the y-intercept (b) so that you can plug them into the following linear equation:
y = mx + b
First, you need to find the slope. You can do this by taking two points on the graph and doing (change in y/change in x):
using (5, 15) and (10, 25),
(25 - 15) / (10 - 5)
= 10/5
= 2
so m = 2
Now, you need to find the y-intercept. Since a graph is provided, you just need to look at the y-intercept, which is 5, so b = 5.
Finally, you just need to put it all together:
y = mx + b, where m= 2 and b = 5,
y = 2x + 5
The orbit of a planet around its star is an ellipse, with the star at one focus. The apoapsis of a planet is its greatest distance from the star, and the periapsis is its shortest distance. Its mean distance is the length of the semimajor axis. The mean distance from a planet to its star is93 million miles. If the apoapsis of the planet is98 million miles, what is the periapsis? Write an equation for the orbit of the planet around the star.The periapsis is ____million miles.
Solution :
Let the center be (0,0)
Now from the diagram given below ,
The major axis = periapsis + apoapsis
2 x semi major axis = periapsis + 98
2 x 93 = 98 + periapsis
Therefore, periapsis = 186 - 98
= 88 million miles
Star coordinate = (93-98, 0)
= (-5,0)
Let the minor axis be 2b
For ellipse [tex]$c^2 = a^2 - b^2$[/tex]
[tex]$(-5)^2 = (-93)^2 - b^2$[/tex]
[tex]$b^2=8624$[/tex]
[tex]$b=\sqrt{8624}$[/tex]
Now, equation of the ellipse
[tex]$\frac{x^2}{(93)^2}+\frac{y^2}{(\sqrt{8624})^2}=1$[/tex]
[tex]$\frac{x^2}{(93)^2}+\frac{y^2}{8624}=1$[/tex]
The equation for the orbit of the planet around the star is;
(x²/93²) + (y²/(√8624)²) = 1
The length of the periapsis of the given planet is;
88 million miles
We are told the orbit around its' star is an ellipse.
We are told that apoapsis of a planet is its greatest distance from the star, and the periapsis is its shortest distance. Thus;
major axis = periapsis + apoapsis
Now, we are told that; the apoapsis of the planet 98 million miles.
Also, that The mean distance from a planet to its star is 93 million miles.
Thus, major axis/2 = 93
Thus, major axis = 93 × 2
Major axis = 186 million miles
Thus;
186 = periapsis + 98
periapsis = 186 - 98
periapsis = 88 million miles
To get the equation of the orbit of the planet around the star, lets first find the focus coordinate.
We know it's y-coordinate will be zero since its the focus but it's x-coordinate will be; 93 - 98 = -5
Thus; star coordinate = (-5, 0)
As we are dealing with ellipse, we have gotten;
a = 93 and c = -5
Thus; b = √(a² - c²)
b = √(93² - (-5)²)
b = √8624
Formula for equation of the ellipse is;
(x²/a²) + (y²/b²) = 1
Thus, we have;
(x²/93²) + (y²/(√8624)²) = 1

f(x)=6(1-x) what is the value of f(-8)
Answer:
54
Step-by-step explanation:
What the shorthand is telling you is wherever you see an x on the right, you put in -8

N=480×10^9
Write N as a product of powers of its prime factors.
Answer:
I got 5^10 x 2^14 x 3
Step-by-step explanation:
1. Do a tree to find 480 as a product of its prime factors
2. You should get 480= 5x2x3x2x2x2x2
3. 10 expressed as a product of its prime factors is 5x2
4. so 10^9 expressed as a product of its prime factors would be
5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2
5. You can then write out 480x10^9 as a product of its prime factors
5x2x3x2x2x2x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2
6. change this to use powers
5^10 x 2^14 x 3
N = 5^(10) × 2^(14) × 3
This is about prime factors
By definition, a prime factor is a factor of a number and that factor is also a prime number.
A prime number is one that is divisible by only itself and 1.
The number we have is; 480 × 10^(9)
Now, let's list the prime factors or 480 and they are;
2, 3, 5
Now, using these prime factors alone to get 480, we have;
5 × 3 × 2 × 2 × 2 × 2 × 2 = 480
In powers, gives;
5 × 3 × 2^(5)
Now,the 10^(9) with the 480 can also be expressed in terms of it's prime factors which are 2 and 5 as;
(5 × 2)^(9)
Expanding this gives; 5^(9) × 2^(9) = 10^(9)
Thus;
480 × 10^(9) = 5 × 3 × 2^(5) × 5^(9) × 2^(9)
This gives;
5^(10) × 2^(14) × 3

Need help ASAP Simplify square root 192
The simplified value of √192 is 8√(3).
The Correct option is C.
To simplify √192, we can look for perfect square factors of 192.
First, let's break down 192 into its prime factors:
192 = 2 x 2 x 2 x 2 x 2 x 2 x 3
Next, we can pair the prime factors into groups of two:
192 = (2 x 2) x (2 x 2) x (2 x 2) x 3
Simplifying:
192 = 4 x 4 x 4 x 3
Now, we can rewrite the square root as the product of the square roots of each perfect square factor:
√192 = √(4 x 4 x 4 x 3)
Applying the property of square roots:
√192 = √(4) x √(4) x √(4) x √(3)
Simplifying:
√192 = 2 x 2 x 2 √(3)
Multiplying:
√192 = 8 √(3)
Therefore, √192 simplifies to 8√(3).
