Which graph represents the function over the interval [−3,3] ? f(x)=⌈x+1⌉

CaHeK987 [17]

Answer: The correct graph is the bottom left graph.

Step-by-step explanation:

Given function is f(x)=ceil(x+1)

To plot graph of f(x) in interval of(-3,3) :

ceil(x+1) is ceiling function

The output of ceil(x) is least integer greater than x

for example ceil(5.5)=6

For an interval of (-3,-2):

Take x=(-2.4)

x+1=(-1.4)

y=f(x)=ceil(x+1)=(-1)

Similarly,

For an interval of (-2,-1):

Take x=(-1.4)

x+1=(-0.4)

y=f(x)=ceil(x+1)=(0)

For an interval of (-1,0)

y=f(x)=1

For an interval of (0,1)

y=f(x)=2

For an interval of (1,2)

y=f(x)=3

For an interval of (2,3)

y=f(x)=4

Thus, The correct graph is the bottom left graph.

What is the soulution to this system of linear equation 7x-2y=-6 8x+y=3

tatuchka [14]

Answer:

(0,3)

Step-by-step explanation:

Step 1: 7x-2y=-6 Step 2: 7x-2y=-6 solve by elimination of the y value

2(8x+y=3)2 +(16x+2y=6)

Step 3: 23x=0, which means x=0

Step 4: subtitute 0 into the equation 8x+y=3

you get 8(0)+y=3, which comes to 0+y=3

you get y=3

therefore the solution to this system is (0,3)

When x is 4, y is 12. If y varies directly as x, which equation relates x and y?

zubka84 [21]

Answer:

12/4

Step-by-step explanation:

y varies directly with x basically means y÷x so you will have to divide the variables together. In other words, it basically means y varies proportionally as x

so in this case, it would be 12 divided by 4 resembling that y varies directly as x
