What is the value of x in the equation (x + 12) = (x + 14) – 3?

Answers

Answer 1

Answer:

Answer: There is NO value of 'x' in the given equation.

Step-by-step explanation: We are given to find the value of 'x' in the equation below:

$(x+12)=(x+14)-3~~~~~~~~~~~~~~~~~~~~(i)$

Finding the value of 'x' in equation (i) means to find the value of 'x' for which the equation is TRUE.

The solution is as follows:

$(x+12)=(x+14)-3\n\n\Rightarrow x+12=x+14-3\n\n\Rightarrow x+12=x+11\n\n\Rightarrow x-x=11-12\n\n\Rightarrow 0=-1,$

which can NEVER be true.

So, the given equation has NO solution.

Thus, there is NO value of 'x' in the given equation.

Answer 2

Answer: (x + 12) = (x + 14) - 3

subtract 12 from each side

x = x + 14 - 3 - 12

Now if we subtract x from each side we see that x - x = 0. Combine the terms left over and we have -1, so

0 = -1

The answer is NO SOLUTION

Given that (2,3) is on the graph of f(x),find the corresponding point for the function f(x) - 4

Answers

The corresponding point for the function f(x) - 4 is (2, -1)

What is a function?

A function in mathematics set up a relationship between the dependent variable and independent variable. on changing the value of the independent variable the value of the dependent variable also changes.

given that (2,3) is on the graph of f(x)

So, for x = 2, f(x) = f(2) = 3

Now, define another function g(x) such that

g(x) = f(x) - 4

g(2) = f(2) - 4

g(2) = 3 - 4 = -1

Hence, corresponding point for the function f(x) - 4 is (2, -1)

a chemist has two alloys, one of which is 10% gold and 15% lead and the other of which is 30% gold and 40% lead. how many grams of each of the two alloys should be used to make an alloy that contains 60 grams of gold and 88 grams of lead

Answers

Let the weight of the first alloy will be x grams.
Weight of gold will be 0.1x grams, weight of lead will be 0.15x grams.
Let the weight of the second alloy will be y grams.
Weight of gold will be 0.3y grams, weight of lead will be 0.4y grams.
Summarizing:
0.1x+0.3y=60 - gold
0.15x+0.4y=88 - lead

0.1x+0.3y=60 * 10
0.15x+0.4y=88 * 100

x+3y=600 * 15
15x+40y=8800

15x+45y=9000
15x+40y=8800

15x+45y=9000 /15
45y-40y=9000-8800

x+3y=600
5y=200

x+3y=600
y=40

y=40
x=600-3*40=480

y=40
x=480

The mean temperature for the first 7 days in January was 9 °C. The temperature on the 8th day was 8 °C. What is the mean temperature for the first 8 days in January

Answers

Answer:

$8.875\°C$

Step-by-step explanation:

Let

x ----> the mean temperature for the first 8 days in January

we know that

The mean temperature for the first 7 days in January multiplied by 7 is equal to the sum of the temperatures for the first 7 days

9(7)=63°C

The sum of the temperatures for the first 7 days plus the temperature on the 8th day, all divided by 8 is equal to the mean temperature for the first 8 days in January

$x=(63+8)/(8)=8.875\°C$

Answer:

8.875 degrees Celsius
