Answer: C
Step-by-step explanation:
5x+3y=13
+(-5x-12y=23)
---------------------
-9y=36
y=-4
To find x plug in y into any equation.
5x+3(-4)=13
5x=25
x=5
Answer:
The figure will change by a factor of 2.25.
Step-by-step explanation:
When the lengths (1-dimensional) change by a factor 1.5 (the definition of <em>dilating </em>a figure), the area (2-dimensional) will change by a factor 1.5 to the power of the quotient of the values of the dimensions, which is 2/1 = 2. So the area will change by a factor of 1.5^2 = 2.25.
Answer:
because either x-6=0 or x+1=0
x-6=0
x=0+6
x=6 OR,
x+1=0
x=0-1
x=-1
