Which system is represented by the graph

a. 3x-y=2 and 3x-y=1
b. 3x+y=2 and 3x-y=1
c. 3x-y=2 and 3x+y=1
d. 3x+y=2 and 3x+y=1

option A. 3x - y = 2 and 3x - y = 1

Step-by-step explanation:

Using the rule of y-intercept which is the value of y when x equals 0

Option A: 3x-y=2 and 3x-y=1

y-intercepts will be ⇒ -2 and -1

Option B: 3x+y=2 and 3x-y=1

y-intercepts will be ⇒ 2 and -1

Option C: 3x-y=2 and 3x+y=1

y-intercepts will be ⇒ -2 and 1

Option D: 3x+y=2 and 3x+y=1

y-intercepts will be ⇒ 2 and 1

Comparing the results with the y-intercepts from the graph

From the graph the system of equation intersects with y-axis, (which mean x=0), at y = -2 , -1

So, the system which is represented by the graph is option A

the diver is 33 feet below the surface.

step-by-step explanation:

hope this

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
