Answer:
by using the identity a square - b square = (a+b)*(a-b)
a = x+y
b=4-x
= (x+y + 4-x)(x+y - 4-x)
y+4 * x+y -4+x
y+4*2x+y-4
2xy+y square -4y + yx + 4x + 4y - 16 +4x
3xy +y square + 8x -16
Step-by-step explanation:
Domain of y = 5^x is the set of all real numbers
Range of y = 5^x is the set of all real numbers y such that y > 0
In interval
notation the domain and range are...
Domain: <span>(−∞,∞)</span>
Range: <span>(0,∞)</span>
y=5^x and x=0 then y=1
which would mean the y-intercept is 1
The point would be (0,1)
were y= 0
Answer: -2
Step-by-step explanation:
The equation of a line in slope - intercept form is given as :

where m is the slope and c is the y - intercept.
Equation given :

⇒ 
add 9 to both sides , we have


comparing with :

slope = -2
