Answer:
Domain: [tex]t \geq 0[/tex]
Range: [tex]v \geq 550[/tex]
Step-by-step explanation:
Given
[tex]v = 550 + 16.5t[/tex]
Required
Determine the domain and the range
Solving for domain:
From the question, we understand that t represent years.
Because years can't be negative;
Then, we can conclude that the domain, t is:
[tex]t \geq 0[/tex]
Solving for Range:
We solved domain to be [tex]t \geq 0[/tex]
This implies that the minimum value of t is [tex]t = 0[/tex] and the maximum is infinity
Substitute 0 for t in [tex]v = 550 + 16.5t[/tex]
[tex]v = 550 + 16.5(0)[/tex]
[tex]v = 550 + 0[/tex]
[tex]v = 550[/tex]
Hence;
The range is [tex]v \geq 550[/tex]
f(x)=2x -7, What is x when f(x)=-15?
Answer:
x = -4
Step-by-step explanation:
Plug in -15 into the equation:
f(x) = 2x - 7
-15 = 2x - 7
Solve for x:
-15 = 2x - 7
-8 = 2x
-4 = x

Answer:
No solution.
Step-by-step explanation:
[tex]5x+6= 5(x+1)-2\\5x+6=5x+3\\5x=5x-3\\0=-3[/tex]
Since 0=-3 is not valid, the equation doesn't have a solution.

Given f(x) = 2x2 – 1 and g(x) = x + 3, find f(g(-5))
Answer:
7
Step-by-step explanation:
f(x) = 2x2 – 1 and g(x) = x + 3,
f(g(-5))
First find g(-5)
g(-5) = -5 + 3
g(-5) = -2
Then substitute into f(x)
f(-2) = 2 ( -2) ^2 -1
= 2 ( 4) -1
= 8-1
= 7

Write 0.39 as a fraction in simplest form.
To write the repeating decimal as a fraction, first let n=0.39. Then
find 100n.
n = 0.39
100n = 39.39
Subtract to eliminate the repeating part.
100n = 39.39
n = 0.39
99n =

Answer: the first one is when you multiply it, the second is where you divide it
Step-by-step explanation:
Because they are different equations that are similar but one just uses multiplication and the other uses division.
4x+57=−133 what is x
4x + 57 = -133
Subtract 57 from both sides.
4x = -190
Divide each side by 4
x = -47.5
answer
-47.5
steps
-133 - 57 = -190
-190 divided by 4 = -47.5

Answer:
14.76
Step-by-step explanation:
First find the length of the diagonal across the bottom using the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
12^2+5^2 = c^2
144+25 = c^2
169 = c^2
Take the square root of each side
sqrt(169) = sqrt(c^2)
13 = c
Then find the length of the diagonal across the middle using the Pythagorean theorem
7^2 + c^2 = d^2
7^2 + 13^2 = d^2
49+ 169 = d^2
218 = d^2
Take the square root of each side
sqrt(218) = sqrt(d^2)
14.76482306 = d
To the nearest thousandth

la cancha de futbol del colegio es de forma rectangular, pedro es el cargado de colocar un lazo alrededor para que nadie entre ala cancha si el ladao largo mide 100 mertros y el lado mas corto mide 64 metros ¿ cuanto debe medir el lazo
Answer:
328 metros
Step-by-step explanation:
Aquí, estamos interesados en colocar un bucle alrededor de un campo de fútbol de la escuela de manera que sea imposible que alguien pueda acceder al campo.
Matemáticamente, la longitud de este bucle sería igual al perímetro del campo.
El perímetro del campo rectangular se puede calcular usando la fórmula; 2 (L + B)
En este caso tenemos; P = 2 (100 + 64)
P = 2 (164)
P = 328 metros La longitud del bucle es de 328 metros.

No solution
Answer:
no solution
Step-by-step explanation:
[tex]-2 ( x + 3) = -2 (x + 1) -4 \\-2x + 3 = -2x -2 -4\\-2x + 3 = -2x - 6[/tex]
add [tex]2x[/tex] to both sides
[tex]-2x + 3 + 2x = -2x - 6 + 2x \\3 = -6[/tex]
That's impossible
so the equation no solution
Answer:
All real numbers ( -∞ ,∞)
Step-by-step explanation:
Simplify [tex]-2(x+3)[/tex]
Apply the distributive property.
[tex]-2x-6=-2(x+1)-4[/tex]
Simplify
[tex]-2(x+1)-4[/tex]
[tex]-2x-6=-2x -6[/tex]
Move all terms containing x to the left side of the equation.
Add 2 x to both sides of the equation.
[tex]-2x-6+2x=0[/tex]
Combine the opposite terms in
[tex]-2x-6+2x[/tex]
add [tex]-2x[/tex] and [tex]2x[/tex]
[tex]0-6= -6[/tex]
[tex]-6= -6[/tex]
Since [tex]-6= -6[/tex] , the equation will always be true for any value of x . All real numbers
The result can be shown in multiple forms.
All real numbers

Solve for Y: when X = 6 y= 2x +1
Answer:
y=13
Step-by-step explanation:
2(6)+1
=12+1
=13
Answer:
y=13
Step-by-step explanation:
by replacing x in the equation with 6 the equation becomes y=2(6)+1 this is just a simple equation that you use to get the answer. 2×6 is 12 and 12+1=13 so y=13.
Can someone please assist me with this? If so praise God :)
Answer:
option 1
Step-by-step explanation:
the square root of 6 is 2.44949, rounded it's 2.4
the square root of 42 is 6.48074, rounded it's 6.5
in option 1 the 6 is placed after the 2 because it is point 4, not quite 2 but a bit bigger than 2 but less than 3.
same thing for 42, it is placed after 6 because it is not quite 6 but not over 7. i hope this helped
