Which of the following expressions is equivalent to 4y + z + y − 8 + 6z

4y + 6z − 8

5y + 7z − 8

4y + 6z + 8

−3y + 7z

Answers

Answer 1
4y + z + y - 8 + 6z

( 4y + y ) + (z + 6z ) - 8

5y + 7z -8
Option B
Answer 2
4y + z + y - 8 +6z
first add all the alike variables
4y + y = 5y
z + 6z = 7z
5y + 7z - 8 is the equivalent variable

Which is the graph of the system of equations y = 3x + 6 and y = 3x +1?
​

Answers

The graph for that equation is the second one hope this helps

Answer:

2nd one with the parallel lines

Step-by-step explanation:

The slope of both the equations is 3. So, if they have the same slope and different y-intercepts then the system of equations are parallel lines.

Describe how to write an equation from a table of values using a graph. No there is not a graph that is all I was given for the question.

Answers

Answer:

Look that the coordinates and trace those points to a corresponding number on the x or y axis. Then write the first number in the coordinate in the x value and the second number for the y value, repeat the process for the rest of the points.

An example is (-3,2), if you see the point (-3,2) on your graph, plug in -3 for the x value and 2 for the y value (don't include this example into your response - it was just for you to see what I mean)

Answer:

just look at the step by step

Step-by-step explanation:

To Write an equation for a table using a graph each point on the coordinate plane. Draw a line through the plotted points. Then,find the y intercept(where the line crosses the Y-axis.) Figure out from the graph what the rise and the run are and calculate the slope.Then,put the equation in y=mx+ b format.

The greatest value of y is y=___, and it occurs when x=
For x between x = π and 2π, the function value y ___ 0

Answers

Answer:

1) Cos

2) 1

3) π

4) 1

5) y < 0

Step-by-step explanation:

1)

Cos

2)

The y-intercept is the value of y when x=0, ie the value of y when the line meets the y-axis. We can see from the graph that this is 1.

3)

The x-intercept is the value of x when y=0, ie the value of x when the line meets the x-axis. We can see from the graph that the smallest positive value of x when the line crosses the x-axis is π.

4)

Highest y value from graph is 1, and besides, for cos graphs, y≤1.

5)

We can see from the graph that between x=π and x=2π, the function is bellow the y-axis, ie y<0.

The graph is of a cos function. The y-intercept of the graph is the function value y=1. The smallest positive x-intercept of the graph is located at x=π. The greatest value of y is y=1, and it occurs when x=2π. For x between x = π and 2π, the function value y<0.

The point on the graph where it crosses the y-axis is known as the y-intercept. The y-intercept in this situation is zero since the graph crosses the y-axis at (0, 0).

The point at which the graph first crosses the x-axis at a positive value of x is known as the graph's smallest positive x-intercept. The graph in this instance crosses the x-axis at (x,0), making the smallest positive x-intercept.

The maximum value of the function is equal to the highest value of y. The greatest value of y in this situation is 1, and it happens when x = 2.

The function value y declines from 1 to 0 for x between x = and 2. You can observe this by examining the graph.
