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.

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!

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
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

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
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
Expression = x

what does this q equal
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
