Answer:
y ≤ (4 - 3x)
Step-by-step explanation:
We have to find the equation of the line which divides the coordinate plane into two different zones.
The line passes through the points (0,4) and (1,1) which is shown on the graph.
So, the equation of the straight line will be
⇒
⇒ y - 4 = -3x
⇒ y = 4 - 3x
Now, the dotted zone shows that y values are equal or less than the value obtained from (4 - 3x).
Therefore, the required inequality is y ≤ (4 - 3x) (Answer)
1: Assuming this line is linear, the first thing to do is find the slope.
The slope formula is
, so in this case, it is
, which comes to
. Then, use your slope and one of the points given to write the point-slope formula of the linear equation, and then written in standard form:
y=
x-
.
2. Use the same process as in question 1 to find:
y=-7x+11
W= 6/5L L=12 inches
W=14.4 inches
perimeter of rectangle = 2(W+L)
=2(14.4+12)
=2(26.4)
=52.8 inches
Answer:
Y = 3x^x is a graph that has exponential growth while y = 3^-x has exponential decay.
Y = 3x^x (-∞, 0) and (∞, ∞).
Y = 3x^-x (-∞, ∞) and (∞, 0).
Step-by-step explanation:
The infinity symbols were being used to represent the x and y values of each graph. I will call y = 3^x "graph 1" and y = 3^-x "graph 2".
When graph 1 had positive ∞ for its x value, its y value was reaching towards positive ∞. When its x was reaching for negative ∞, its y was going for 0.
For graph 2, however, when its x was reaching for positive ∞, its x was reaching for 0. When its x was reaching for negative ∞, its y was going for positive ∞.
