Answer:
g(x)=4x-48
Step-by-step explanation:
f(x)=0.25x + 12
substitute
f(x) with y
y=0.25x + 12
then replace x with y and y with x
x=0.25y + 12
swap equation
0.25y + 12 = x
0.25y = x - 12
divide both sides by 0.25
Y=4x-48
To solve this problem you must apply the proccedure shown below:
1- You have that the laddder makes an angle of 
with the ground and the top of the ladder reaches 
.
2- Therefore, you have:
Where:
3-You must substitute values and solve for the lenght, as following:
Therefore, the answer is: 
3/5 is 12/20 simplified. :)
1. Find the greatest common factor of 12 and 20 which is 4.
2. Divide 12 by 4 and 20 by 4.
3. 12/4=3 and 20/4=5
4. 3/5!
the answer is x+y≤2
The sum of x and y is greater than or equal to 2
Answer:
54°
Step-by-step explanation:
Since m<2 + m<1 is equal to 180, we can set up the equation to find m<1.
plug in 126 as m<2, so we get
126 + m<1 = 180
-126 -126
m<1 = 54.
From this knowledge, we know that
7.) 54°
8.) 126°
9.) 54°
10.) 126°
11.) 54°
12.) 126°
13.) 54°
14.) 126°
