To see if 8 is the solution to the equation, 3 (x - 2) + 4 = 22, you must replace x with 8 and solve using the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction) REMEMBER: IF NOT APPLICABLE TO THE EQUATION YOU MAY SKIP THAT STEP IN PEMDAS . If the sides are equal to each other then 8 IS a solution.
3(8 - 2) + 4 = 22
Parentheses...
3(8 - 2) + 4 = 22
8 - 2 <<<In the parentheses so you must solve first
6
so...
3(6) + 4 = 22
Multiplication...
3(6) + 4 = 22
3 * 6
18
so..
18 + 4 = 22
Addition...
18 + 4 = 22
18 + 4
22
so...
22 = 22
Are they equal to each other? YES!!!
8 is a solution to the equation 3 (x - 2) + 4 = 22

Answer:
A' - 1,1
B' - 2,-1
C' - 3,0
D' - 2,1
Step-by-step explanation:
in order to do this problem, you would first reflect every point over the X axis. this then makes it a polygon in quadrant 4. from there, you would move each point up 2 points. this would mean that every X value stays the same. the only value that changes in this scenario is the Y value. This is not always true so do not use this rule unless you know for sure. Hope this helps!!
Answer:
2. 30 ft
3. 50 ft.
Step-by-step explanation:
2. The contour map of a place is shown in the diagram.
The point E is placed near to the 30 ft contour line.
Therefore, the elevation of the point E on the map is 30 ft. (Answer)
3. From the same contour map shown in the diagram, it is clear that,
The point F is placed near to the 50 ft contour line.
Therefore, the elevation of the point F on the map is 50 ft. (Answer)
