What are Absolute Value Equations​

Mathematics
1 answer:
nikdorinn [45]3 years ago
5 0

Absolute Value Equations are equations that look like this:

I x + 5 I = 15

They have 2 solutions almost all the time. To solve this equation we do this:

x+5=15      x+5=-15

Then you solve them:

x+5=15      x+5=-15

x=15-5       x=-15-5

x=10           x=-20

The solutions would be x=10 and x=-20 .

In some cases, you only have one solution:

I x + 5 I = 0

0 cannot be negative, so we only have one equation to solve:

x+5=0

x=0-5

x=-5

The one solution would be x=-5 .

In some OTHER cases, you have no solution. This happens when the absolute value equation equals to a negative number:

I x + 5 I =-10

Absolute value solutions are always going to end up positive because absolute value turns the number, negative or positive, into a positive.

Resolver la siguiente ecuación por eliminación o sustitución: a-8b= -9 a-2b= -7
Crazy boy [7]

Answer: Solution: a=\dfrac{-19}{3} and b=\dfrac{1}{3} .

Step-by-step explanation:

The given pair of equations:

a-8b= -9\ ...(i)\\\\ a-2b= -7\ ...(ii)

Eliminate equation (i) from (ii) , we get

-2b-(-8b)=-7-(-9)\\\\\Rightarrow\ -2b+8b=-7+9\\\\\Rightarrow\ 6b=2\\\\\Rightarrow\ b=\dfrac{1}{3}

Put value of b in (ii) , we get

a-2\times\dfrac{1}{3}=-7\\\\\Rightarrow\ a=-7+\dfrac{2}{3}\\\\\Rightarrow\ a=\dfrac{-21+2}{3}\\\\\Rightarrow\ a=\dfrac{-19}{3}

Solution: a=\dfrac{-19}{3} and b=\dfrac{1}{3} .

Find the value of x so that the function has the given value. f(x) = 6x + 9; f(x) = 21
Olin [163]

Answer:

x = 2

Step-by-step explanation:

We need to find the value of x so that the value of given function becomes 21 .

We have ,

f(x)=21\\\\ f(x)= 6x + 9

Now , for finding x ,

6x +9 = 21 \\\\ 6x = 21 -9 \\\\ 6x = 12 \\\\ x = 2

the angle of elevation from the tip of the shadow to the top of the tree is 36 degrees. find the distance from the top of the tr
Bas_tet [7]
In order to fully understand the problem, it is best to sketch it. Sketching the system, we will see that the system forms a triangle where the angle of elevation is 36 degrees. We are asked to find the hypotenuse. We can use a trigonometric function. It should be noted that one of the sides should also be given in order to calculate the hypotenuse. Trigonometric functions that can be used are:

sin(theta) = opposite / hypotenuse
cos(theta) = adjacent / hypotenuse
