I thick its C for the answer
706286 to the nearest ten thousand is 706,000
Answer:
It's very simple, all you have to do is round the place that is underlined. So for the first question, 6,9<u>9</u>5,000, the 3rd number there is underlined. (Which is the number 9) So you will have to round to the nearest ten thousand. The answer for number 1 is 7,000,000.
Step-by-step explanation:
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:
Step-by-step explanation:
If "a" represents the number of adult smoothies sold, then 260-a is the number of smoothies sold to children. The total revenue is ...
3a +1(260-a) = 675
2a +260 = 675 . . . . . . eliminate parentheses
a + 130 = 337.5 . . . . . . divide by 2
a = 207.5 . . . . . . . . smoothies sold to adults
260-a = 52.5 . . . . . smoothies sold to children

For the given numbers, this is the way it works out. The "half" values suggest there is a typo somewhere, possibly in the curriculum material. Talk to your teacher about this one.
