Answer: s + d = T
Step-by-step explanation:
You have to add s and d together to get T.
Furthermore, for Friday you must subtract, T - s = d.
We see that we have some nasty sqrt signs
try to use x values that yield perfect squares inside the sqrt sign like 1,4,9,16, or ones that make the inside 0
first one
y=-4+√(x+2)
try some nice values for ease of graphing
ok so try x=-2
y=-4
(-2,-4)
x=-1
y=-3
(-1,-3)
x=-1
y=-3
(-1,-2)
if x=7
y=-1
(7,-1)
if x=14
y=0
(14,0)
so we have
(-2,-4)
(-1,-3)
(2,-2)
(7,-1)
(14,0)
second one
y=2+√(x+1)
if x=-1
y=2
(-1,2)
if x=0
y=3
(0,3)
if x=3
y=4
(3,4)
if x=8
y=5
(8,5)
we have
(0,3)
(-1,2)
(3,4)
(8,5)
first one
y=-4+√(x+2)
so we have
(-2,-4)
(-1,-3)
(2,-2)
(7,-1)
(14,0)
second one
y=2+√(x+1)
(0,3)
(-1,2)
(3,4)
(8,5)
Answer:a
Step-by-step explanation:
Answer:
x=6
Step-by-step explanation:
2x+7=9x-35
-2x -2x
(two cancels out on left side and 9x becomes 7x)
7=7x-35
+35 +35
(35 cancels on right side and is added to left)
42=7x
/7 /7 (divide both sides by 7)
x=6
