Answer:
Step-by-step explanation:
To make this easier, to get ride of the fractions, we can multiply both sides by 4
now use the distributive property
now we want to isolate x to one side and isolate all the constants to the other
now simplify
to test, we can plug in back to the original
it works
The complete question in the attached figure
we know that
area of rectangle=width*length
width=
yd
length=
yd
yd²
Answer:
D: The slope is 3
Step-by-step explanation:
To figure out the slope, which is always a constant, you simply figure out the average displacement using the points we already know. This is described by the equation y2-y1/x2-x1. Let's use the ordered pairs (-3, 2) and (-1, 8) to figure this out.
8-2/-1-(-3) = 6/2 = 3
Another method you could use is to graph the points and figure out how many units y has to go up for every x over, or the "rise over run"
Either way, your slope is 3.
Answer:
The two numbers are 5 and 1. Their product is 5
Step-by-step explanation:
x + y = 6 (*)
x - y = 4 (**)
Let (*) + (**)
--> (x+y) + (x-y) = 6 + 4
<=> 2x = 10 <=> x = 5
Substitute x= 5
(*) <=> 5 + y = 6
<=> y=1
Answer: (x,y) = (5,1)
Their product: x.y = 5x1 = 5
