The sets X and Y exists collectively referred to as the function's domain and codomain, respectively.

If the function be 6x + 3y = −1 then the value of y = (−1 - 6x) / 3.

A function in mathematics from a set X to a set Y assigns exactly one element of Y to each element of X. The sets X and Y exists collectively referred to as the function's domain and codomain, respectively.

The characteristic that every input is associated to exactly one output defines a function as a relationship between a set of inputs and a set of allowable outputs.

A mathematical phrase, rule, or law establishes the link between an independent variable and a dependent variable (the dependent variable).

Let the given function be 6x + 3y = −1.

⇒ 3y = −1 - 6x

simplifying the above equation, we get

⇒ y = (−1 - 6x) / 3

Therefore, the value of y = (−1 - 6x) / 3.

Answer:

Expression: 18 - 12 + 7. In 3 days, the temperature will be 13 degrees.

Step-by-step explanation:

The temperature is 18 degrees.

It will decrease 12 degrees after one day. So, it is 18 - 12.

Then it will increase by 7 degrees after another day. So, it is 18 - 12 + 7.

18 - 12 = 6. 6 + 7 = 13.

So, the expression is 18 - 12 + 7 and the answer is 13 degrees (i think)

Explanation:

Use the remote interior angle theorem. This says a pair of interior angles always add to the measure of the exterior angle that is not adjacent to any of the interior angles, so basically what your diagram is showing.

(interior angle C) + (interior angle D) = exterior angle

(46) + (-1+8x) = 18x+5

8x+45 = 18x+5

8x-18x = 5-45

-10x = -40

x = -40/(-10)

x = 4

Answer:

C

Step-by-step explanation:

The explicit formula is aₙ = -6 · 2⁽ⁿ⁻¹⁾, and we want to find the 9th term in the sequence. To find it, we can simply substitute n = 9 into the explicit formula, which gives us:

a₉ = -6 · 2⁽⁹⁻¹⁾

= -6 · 2⁸

= -6 · 256

= -1536

Answer:

(sin(A) + cos(A)).sec(A) = 17/12

Step-by-step explanation:

tan(A) = 5/12

sin(A) = 5/13

cos(A) = 12/13

sec(A) = 1/(cos(A)) = 13/12

(sin(A) + cos(A)).sec(A) = (5/13 + 12/13).13/12

= 17/13.13/12

= 17/12

Answer: 240 men

Step-by-step explanation:

From the question, we are informed that there were 600 performers in a dance recital and that the ratio of men to women is 4:6.

Fraction of men at the recital = 4/10

Fraction of women at the recital = 6/10

The number of men performers that were in the dance recital will be:

= 4/10 × 600

= 240 men

There were 240 men at the recital.

Answer:Roots of a number indicates value where function will be zero. If an equation let's say

y = f(x) = x^2 -3x + 2 has two roots x = 1 and x =2 . Now if you will draw the graph, line will cross x-axis at 1 and 2 indicating y will become zero at 1 and 2. But if any equation has imaginary roots implies y will be never be zero for any real value of x and as we do not show imaginary number on a Cartesian plane we cannot make y =0 hence graph will never touch x-axis.

Step-by-step explanation:

3636-72.72= 3563.28

Step-by-step explanation:

The triangle is isosceles, so the base angles are the same.

All three angles add up to 180°.

(6x + 4) + (6x + 4) + (18x − 8) = 180

30x = 180

x = 6

Answer:x=6

Step-by-step explanation:since those two sides shown are the same length, the missing angle is also 6x+4. the angles on a triangle always will equal 180. so you set the problem up as 6x+4+6x+4+18x-8=180. when you combine like terms it is then 30x=180. x=6

Answer:

  a.  0.81

  b.  v = 28000(0.81^n)

  c.  2757.36

Step-by-step explanation:

a. The growth factor is 1 more than the growth rate. Here, the growth rate is -19% (per year), so the growth factor, the multiplier, is ...

  1 -0.19 = 0.81

__

b. The equation sets value equal to the original value multiplied by the growth factor to the power of the number of years:

  value = (original value) × (growth factor)^n

  v = 28000(0.81^n)

__

c. For n=11, this is ...

  v = 28000(0.81^11) ≈ 2757.36

The value of the truck after 11 years is about $2757.
