Answer:

x=-10

Step-by-step explanation:

3x-4(2+3x)=82

3x-(4*2)+(4*3x)=82

3x-8-12x=82

-9x-8=82

-9x-8+8=82+8

-9x=90

-9x/-9=x

90/-9=-10

x=-10

Answer:

10 isn't the right answer

Step-by-step explanation:

multiply everything in the parenthesis by -4

you would get 3x-8-12x=82

then combine like terms to get -9x

once your equation is in simplist form it will look like

-9x-8=82

next you add 8 to the 82

-9x=90

then divide 90 by -9 and you would get

x=-10

Pooja's plant began sprouting 222 days before Pooja bought it, and she had it for 989898 days until it died. At its tallest, the
MakcuM [25]

Answer:

Step-by-step explanation:

Given:

function h(t) models the height of Pooja's plant (in cm) where

t is the number of days after she bought it.

Now we have to find about which number type is more appropriate for the domain of h.

That means what values can be taken by the variable "t".

As per the questions, t represents number of days not the hours so it will not be in decimal or fraction value. It can only use integer values for the number of days. like 1, 2, 3 ...,n  

Now as the time is counted after she bought the plant then number of days will be positive.  

Hence answer for the type of domain can be positive integers or you can say integers greater than or equal to 0.

 If the equation y = 15x + 2 is changed to y = 15x - 4, how will the graph of the line change?
igomit [66]
The y-intercept is changed from 2 to -4.

That means that the point that the graph crosses the y axis has been moved down by 6.

Since the slope of the line has not changed, this just means the graph of the line will be moved down by 6.

Hope this helps!
