Y-y1=m(x-x1)
y+3=m(×-0)
y=mx-3
So,
There are 5 times as many yellow labs (call them y) as terriers (call them t).
5t = y
There are 18 dogs total.
t + y = 18
Substitute 5t for y in the second equation.
t + 5t = 18
6t = 18
Divide both sides by 6.
t = 3
There are three terriers and 15 yellow labs.
So the system of equations would be:
5t = y
t + y = 18
As for the model, you can have a circle represent the number of terriers. Since there are 5 times as many yellow labs as terriers, you will have to have five more circles. Adding them up, you will have 6 of the circles, or 6 times circle. The total is 18, so 6 of the circles is 18. 6 times what is 18? 3. Therefore the circle, and therefore the number of terriers, is 3.
The surface area of a sphere is
and if the original S.A was is enlarged to have it 9 times greater, the radius would be multiplied by 3 or roughly 2.99626 rounded off to 3.0.
For example, let us assign values.
Let A=90
A= 90*9 = 810
and
the first r is 2.68 and the second r is 8.03
then,
or rounded off to 3.
Answer:
{2, 4, 6}
Step-by-step explanation:
the domain is the interval or set of valid x (input) values.
the range is the interval or set of valid y (result) values.
just use the x values in the functional definition and collect the results. these are the range.
x = -1
y = 2×-1 + 4 = 2
x = 0
y = 2×0 + 4 = 4
x = 1
y = 2×1 + 4 = 6
