What is the range of the function f(x) = 3x + 2
when the domain is {-2,-1,2}?
Answer:
Im going to give them as ordered pairs, you can pick out the range (Y values): (-2,-4), (-1,-1), (2,8)
Step-by-step explanation:
All that needs to be done for this problem is one thing: substitute the given domain values for the "x" in the equation. Domain is just a fancy way of saying x coordinate. All f(x) is is "function of x." This can still be your Y coordinate, or your range. I hope this process helps!

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.

3(x+9)^3/4=24
Answer:
The solution is x= 2 cubic root 4 -9 or -5.825
Step-by-step explanation:
3(x+9)^3/4=24
3(x^3 + 27)/4=24
3x^3+81/4=24
0.75x^3 +20.25=24
0.75x^3=2.75
x= 2 cubic root 4 -9 or -5.825
Find the value of x.
Answer:
for this problem we use the sine function
[tex] \sin(x) = \frac{opp}{hyp} \\ \sin(38 ) = \frac{x}{100} [/tex]
multiply both sides of the equation by 100
[tex]100 \sin(38) = \frac{100x}{100} [/tex]
100 cancels on the right hand side of the equation
[tex]100 \sin(38) = x \\ x = 61.566\:ft[/tex]

Prove the following relations: 1) (1 - cos²A) (1 + tan²A) = tan²A
Step-by-step explanation:
(1 - cos²A)(1 + tan²A) = tan²A
1 + tan²A - cos²A - cos²A · tan²A = tan²A
1 + tan²A(1 - cos²A) - cos²A = tan²A
1 - cos²A + tan²A(sin²A) = tan²A
sin²A + tan²A(sin²A) = tan²A
sin²A (1 + tan²A) = tan²A
sin²A (sec²A) = tan²A
sin²A (1/cos²A) = tan²A
(sin²A)/(cos²A) = tan²A
tan²A = tan²A → Proved

resolver el sistema x-y =6 y este otro 2x+5y= -2 porfaaaa es para mañana
Answer:
x =4
y = -2
Step-by-step explanation:
a) x - y = 6
b) 2x + 5y = - 2
a) x = y + 6
b) 2(y+6) + 5y = -2
2y + 12 + 5y = -2
7y = -2 -12
y = -14/7
y = -2
a) x - (-2) = 6
x +2 = 6
x = 6-2
x = 4

Select the correct line. Which line is perpendicular to AB
Answer:
line 1
Step-by-step explanation:
perpendicular is the opposite so therefore line 1 is the answer
From the given figure, line AB perpendicular to line 1.
We need to check which line is perpendicular to AB.
What are perpendicular lines?In elementary geometry, two geometric objects are perpendicular if they intersect at a right angle. The condition of perpendicularity may be represented graphically using the perpendicular symbol, ⟂. It can be defined between two lines, between a line and a plane, and between two planes.
From the given figure we can see that line AB perpendicular to line 1.
The line AB perpendicular to line 1, intersect each other and made an angles 90°.
Therefore, from the given figure, line AB perpendicular to line 1.

Answer:
30 degrees
Step-by-step explanation:
Since all triangles' angles add up to 180 degrees, you can add the sum of the angles you already know and subtract it from 180.
126+24=150
180-150=30
so angle Q = 30 degrees

To isolate the variable in 1/4x multiply by _ or divide by _
Answer: To isolate the variable in ¹/₄ x multiply by 4 or divide by 1
Step-by-step explanation:
Let ¹/₄ x = a
multiply by 4: 4 (¹/₄) x = 4 a
1 x = 4 a
divide by 1: ¹/₁ x = ⁴/₁ a
x = 4a [x is now isolated]
To isolate the variable in 1/4x multiply by 4 or divide by 1/4
How to isolate the variable in 1/4xFrom the question, we have the following parameters that can be used in our computation:
Expression = 1/4x
To isolate the variable in 1/4x, we multiply by 4
So, we have
Expression = 1/4x * 4
Expression = x
OR
To isolate the variable in 1/4x, we divide by 1/4
Expression = 1/4x / 1/4

Determine if (0,-5) is a
solution to the equation
y = -5x
Plug (0,-5) into the equation -
-5 = -5(0)
-5 times 0 is 0
-5 = 0
(0,-5) is NOT a solution to the equation.
Good luck!
Answer:
No, it is not the solution to the equation.
Step-by-step explanation:
(0, -5)
y = -5x
So we have to plug in the values for x and y. 0 is our x value and -5 is our y value.
-5 = -5(0)
-5 = 0
Therefore, (0, -5) is not a solution to the equation
