Answer:
X = -5
Step-by-step explanation:
-6x + 18 = 7 - (4x + 9)
first we simplify the parentheses.
distribute the invisible number one created by the negative sign in front of the parentheses to get -6x + 18 = 7 - 4x - 9
then simplify further by subtracting 9 from the right side, leaving you with
-6x + 18 = -2 - 4x
next, add 2 to both sides to isolate the variable.
-6x + 20 = -4x
then, to isolate the variable further add 6x to both sides.
20 = -4x
divide both sides by -4 to isolate the variable
-5 = x
so, x = -5
5 is 3x less than 15 so you find 3x less than 18 to get 18/3 or 6ft... so your answer is B. Hope this helps
20 minutes is 1/3 of an hour
14 x 3 = 42
He delivers 42 papers per hour
126 / 42 = 3 hours
The answer is c
Answer:
Side B'A has a slope of 1 and is perpendicular to side BA
Step-by-step explanation:
When rotating clockwise 90 degrees x,y will become y,-x so lets apply this to the points.
A=(3,5) -->(5,-3)
B=(1,3)-->(3,-1)
C=(5,-1)-->(-1,-5)
D=(7,1)-->(1,-7)
Now that we have the coordinates for A'B'C'D' we will graph both rectangles, (you can do this using Geogebra you wont need an account)once graphed we can draw a long straight line using a straightedge through points BA and B'A' to see that they eventually intersect and the line through B'A' goes through 1 on the x-axis.
