Answer:
(0.6)
Step-by-step explanation:
the y intercept is determined by wherever x = 0
the ordered pair (0,6) has the x value equaling 0
therefore (0,6) represents the y-intercept
We have a line passing through 3 points. We can use the first
two points to find the equation of the line.
(6,3), (8,4)
slope m = (4-3)/(8-6) = 1/2
We can use the point slope form y-y1 = m(x-x1) or
the slope intercept form y = mx + b
to find the equation of the line.
Let's take the point (6,3) and use y = mx + b to find b
y = 3, x = 6, m = 1/2
3 = (1/2)(6) + b
3 = 3 + b
0 = b
The equation of our line is y = (1/2)x
We have a line of equation y = (1/2)x going through point (n,-2)
Plugging in we have: -2 = (1/2)n
2(-2) = n
-4 = n
Your answer is n = -4
NOTE: looking at the 3 points as given initially: (6,3), (8,4), (n,-2)
We can see that 3 = (1/2)6 and 4 = (1/2)8 so -2 = (1/2)n makes sense
Hope this helps you :)
Answer:
0.5x+0.3y >= 3
sorry I don't know how to make the less than or equal to sign
Step-by-step explanation:
he can buy X amount of gumballs if he buys Y amount of jawbreakers and that will be less than or equal to $3
to graph, you must plug the number 0 into the X spot and solve.
0.5(0) +0.3y >= 3
next plug in for Y
0.5x+0.3(0) >= 3
plot these two points on the graph and draw a line through them
Answer:
This is a theory.
Step-by-step explanation:
The sialic continents, mafic ocean floors, the crust, the mantle and the core were all formed while the early melted Earth cooled and differentiated as low density minerals floated to the surface and heavy, denser minerals sank to the center.
This is a theory.
