Given the function f(x) = 2x + 5, what would the input be with an output of -9

Answers

Answer 1

Answer:

The input is -7

Step-by-step explanation:

f(x) = 2x + 5,

Let f(x) = -9

-9 = 2x+5

Subtract 5 from each side

-9-5 =2x+5-5

-14 =2x

Divide by 2

-14/2 =2x/2

-7 =x

Answer 2

Answer:

The would be -7.

Step-by-step explanation:

Given function :-

f ( x) = 2x + 5.

given output, f( x) = -9

plug the f(x) as -9.

-9 = 2x + 5

Move the constant to the left hand side and change their sign.

-9 - 5 = 2 x-14 = 2x

Divide both side by 2.

-14/2 = 2x / 2-7 = x

Therefore, the input of this function would be -7.

Cai left his house for work and was gone 4 2/3 hours. he spent a total of 5/6 hours driving to and from work and didnt go anywhere else. How long was he at work?

A.5 1/2 hours
b. 3 5/6 hours
c. 3 1/6 hours
d. 4 1/6 hours

Answers

Answer:

[tex]4\frac{1}{6}[/tex] hours

Step-by-step explanation:

Substract total hours from hours Cai spent driving to find how long he was at work.

[tex]4\frac{2}{3}[/tex] - [tex]\frac{5}{6}[/tex] = ?

Substract the second expression [tex]\frac{2}{3} - \frac{5}{6}[/tex] by the first expression 4.

[tex]\frac{25}{6}[/tex]

Convert to a mixed number.

[tex]4\frac{1}{6}[/tex]

Therefore, the answer is [tex]4\frac{1}{6}[/tex] hours.

The measures of the angles of a triangle are shown in the figure below. Solve for X.
75°
(7X+14)
49°

Answers

Answer;

x=6

Step-by-step explanation:

Step-by-step explanation:

Angle in a triangle is 180

75+ (7x+14) +49 =180

75+ 49+ (7x+14)= 180

124+ (7x+ 14) = 180

124+ 14 +7x= 180

138+7x = 180

7x =180- 138

7x=42

x= 6

Given the relation {(2, 3), (-2, 2), (1, 5), (0, -1)}, state the domain.

B. {-2, 0, 1, 2}

C. {-1, 0, 1, 2}

D. {-2, -1, 0, 3}

Answers

Answer:

C.{-1,0,1,2}

Step-by-step explanation:

B is the correct answer. The domain is the set of x-coordinates within the function; it shows how far left or right the function on the x-axis.

The Domain of the function is {-2, 0, 1, 2}. These are the x-coordinates contained within the function. They are in numerical order. The first x-coordinate shows how far left the function is to the x-axis (-2) and the last right coordinate (2) shows how far right the function is to the x-axis.

So, your answer is B.

Step-by-step explanation:

Since d represents the amount of boxes of donuts, you would need to multiply d in the equation by 6.5 or $6.50 since the problem states that 1 dozen donuts costs $6.50 (assuming 1 box contains 1 dozen donuts). $6.50d would have to equate or equal to $25 because the equation 25 = 6.5d shows the most amount of boxes of donuts Tucker could purchase with $25.

If you were wondering, Tucker could purchase up to 3 boxes donuts with $25.

Answer:

cost of 1 box = $6.50

Which of the following does not represent a function?

Answers

Answer:

i think it's C sorry if it's wrong

Step-by-step explanation:

i took the test and got it right so

Answer:

The third option

Step-by-step explanation:

1. To determine whether a relation is a function given a graph, use the

following criterion:

if every vertical line you can draw goes though only 1 point, then the relation is a function If you can draw a vertical line that goes though 2 or more points, y is  not a function of x.  This is called the vertical line test.

2. As you can see, if you draw a vertical line at a specific place in the third graph, it will go through 2 or more points.

Therefore, the correct answer is the third option/graph.

Bronze which costs $7.05/kg is made by
combining copper which costs $6.20/kg with
tin which costs $8.70/kg. Find the number of
kg of copper and tin required to make 5 kg of
bronze.
Find the number of kg of copper and tin required to make 15.3 kg of bronze. (NO LINKS)

Answers

Answer: 3.3 kg of Cu, 1.7kg of Sn

I abbreviate copper as Cu and tin as Sn.

Step-by-step explanation:

For 5 kg of $7.05$/kg bronze:  Let x be the mass of Cu.  The mass of Sn would be 5-x.

Multiply these two masses by their respective element cost.

Cu = ($6.20/kg)x  [The total value of copper in 5 kg of bronze]

Sn = ($8.70/kg)(5-x)  [The total value of tin in 5 kg of bronze]

We know that:

($6.20/kg)x + ($8.70/kg)(5-x) = $7.05

Solve for x.  I get

x= 3.3 kg of Cu

5-x = 1.7kg of Sn

==

Check the result for 5 kg of bronze:

(3.3 kg of Cu)*($6.20/kg) = $20.46 cost of Cu

(1.7kg of Sn)*($8.70/kg) =     $14.79  cost of Sn

Thus, the total cost for 5kg of bronze is $35.25.  That makes it $7.05/kg.
