Answer:
x = -2
Step-by-step explanation:
-2x + 4x = -4 + 0
2x = -4
2x/2 = -4/2
x = -2
Hope this helps.
First use the point slope form
y-y1=m(x-x1)
plug in the ordered pair to the y1 and x1 so
y--3=m(x--8)
add the slope and make the double minus into a plus
y+3=34(x+8)
then you can distribute the 34
y+3=34x+272
then to get it to slope intercept you subtract 3 from both sides of the equation to make it y=mx+b so
y=34x+269
Answer:
two: +1 and -1
Step-by-step explanation:
If a number is equal to its own reciprocal, it will satisfy the equation ...
x = 1/x
Multiplying by x and subtracting 1 gives ...
x^2 -1 = 0
This factors as ...
(x -1)(x +1) = 0
By the zero product rule, the solutions are those values of x that make one or more factors zero:
x = 1
x = -1
There are two self-reciprocals.
Is there supposed to be a picture?
Answer:
600 cubic feet of water
Step-by-step explanation:
If the pool is filled 4 feet and the pool is 5 feet deep, that leaves 1 foot of depth left to fill. This makes the volume equation 30 x 20 x 1 which equals 600.
