Answer:
12x-6
Step-by-step explanation:
Answer: 15
Step-by-step explanation: Label the tree with 4m for the height of the tree and the base of the triangle 15m for the shadow it cast. The angle is adjacent to 15m and opposite to 4m making the equation you use tanx=4/15 which when you solve becomes tan^-1(4/15) which gives you 15.
Answer:
Divide by 5, then multiply by 9, then add 32
Step-by-step explanation:
By solving an absolute value equation, we will see that the two solutions are:
x = 49 and x = -41
<h3>
How to solve the equation for x?</h3>
First, we need to write the equation, we will get:
(1/5)*|x - 4| - 3 = 6
That is an absolute value equation, first let's isolate the absolute value part on the left side, so we get:
(1/5)*|x - 4| = 6+ 3 = 9
|x - 4| = 9*5 = 45
Now we have the simpler equation:
|x - 4| = 45
Which can be written in two ways:
x - 4 = 45
x - 4 = -45
So we will have two solutions for x:
x = 45 + 4 = 49
x = -45 + 4 = -41
These are the two possible values of x.
