Y = -2x + 6....so we sub in -2x + 6 for y in the other equation
3y - x + 3 = 0
3(-2x + 6) - x + 3 = 0
-6x + 18 - x + 3 = 0
-7x + 21 = 0
-7x = -21
x = -21/-7
x = 3
now we sub 3 in for x in either of the original equations to find y.
y = -2x + 6
y = -2(3) + 6
y = -6 + 6
y = 0
so ur solution is : (3,0)
Answer:
C. 10
Step-by-step explanation:
We are given a graph representing the height of the elevator with respect to time.
Since, we know that,
X-axis represents the 'time' in seconds and y-axis represents the 'height of the elevator' in feet.
As, the coordinate points on the graph are given by,
(1,10), (2,20), (3,30) and (4,40).
So, the rate of change can be found out by solving,
.
Hence, the rate of change of the relationship is 10.
You would do 5 divided by 4
the question is tells us that the sandwiches are being shared equally so it is the total amount. it is being distributed to 4 friends meaning it is being divided by 4.
5 divided by 4 = 1.25
they all got 1.25 of the sandwiches
Answer:
(d) The parabola g(x) will open in the same direction of f(x), and the parabola will be wider than f(x).
Step-by-step explanation:
We assume you intend ...
f(x) = equation of a parabola
g(x) = 2/3·f(x)
Multiplying a function by a factor of 2/3 will cause it to be compressed vertically to 2/3 of its original height. When the function is a parabola, this has the effect of making it appear wider than before the compression.
__
The compression factor is positive, so points on the graph remain on the same side of the x-axis. The direction in which the graph opens is not changed.
The attachment shows parabolas that open upward and downward, along with the transformed version.
