Answer:
x=17, y=9. (17, 9).
Step-by-step explanation:
x+y=26
3x+8y=123
------------------
x=26-y
3(26-y)+8y=123
78-3y+8y=123
78+5y=123
5y=123-78
5y=45
y=45/5
y=9
x=26-9=17
Answer:
Step-by-step explanation:
we know that
The equation of a exponential growth function is given by
where
y is the population of rabbits
x is the number of years since 1991
a is the initial value
r is the rate of change
we have
substitute
For the year 1998
the number of years is equal to
x=1998-1991=7 years
so
we have the ordered pair (7,18,000)
substitute in the exponential equation and solve for r
elevated both sides to 1/7
therefore
Predict the population of rabbits in the year 2006
Find the value of x
x=2006-1991=15 years
substitute the value of x in the equation
<h2><em>Okay so these are the answers from top to bottom.</em></h2><h2><em>x = 2 and y = x + 8 so 2 + 8 = 10.</em></h2><h2><em>x = 0 and y = x + 8 so 0 + 8 = 8.</em></h2><h2><em>x = 4 and y = x + 8 so 4 + 8 = 12.</em></h2><h2><em>10</em></h2><h2><em>8</em></h2><h2><em>12</em></h2><h2><em>Hope this helps and have a great day...!</em></h2>
The model suggests the equation 3x-4 = 6-2x and the solution is x = 2.
What is equation?
In arithmetic, associate equation could be a formula that expresses the equality of 2 expressions, by connecting them with the sign =
Main body:
According to question,
there are 3 bars for x and 2 bars for -x so it shows
The equation becomes :
3x - 4 = 6-2x
5x = 10
x =2
Hence the solution to this equation is 2.
