Answer:

  1. 18x
  2. 4x - 3y + 9z

Step-by-step explanation:

1) 7x + 11x = 18x

2) 3x - 2y + 4z - 2x - 3y + 5z + 6x + 2y - 3x

= 3x - 2x + 6x - 3x - 2y - 3y + 2y + 4z + 5z

= 4x - 3y + 9z

Solve the following system of equations and show all work.<br> y = 2x^2 +9x<br> y = 4x + 25
Genrish500 [490]

Answer:

x = 5/2 thì y = 35 và x = -5 thì y = 5

Step-by-step explanation:

thay y = 4x + 25 vào phương trình y = 2x ^ 2 + 9x ta có:

4x + 25 = 2x ^ 2 + 9x

⇒2x ^ 2 + 5x - 25 = 0

⇒ x = 5/2 và x = -5

thay x = 5/2 vào phương trình y = 4x + 25 ⇒ y = 4*(5/2) + 25 = 35

thay x = -5 vào phương trình y = 4x + 25 ⇒ y = 4*(-5) + 25 = 5

Explain the following terms: positive slope, negative slope, x-intercept, y-intercept &lt;&lt; Read Less
garik1379 [7]
Hello there!

A positive slope is represented in a linear equation by a positive coefficient behind the x term. A positive slope means that the graph is on an increasing interval as x approaches +∞. In a more simple way, a positive slope means that the graph is going up from left to right.

A negative slope is represented in a linear equation by a negative coefficient behind the x term. A negative slope means that the graph is on a decreasing interval as x approaches +∞. In a more simple way, a negative slope means that the graph is going down from left to right.

The x intercept(s) of a graph are where the graph touches the x-axis. These are also known as the zero(s) OR solution(s) of the function.

The y intercept(s) of a graph are where the graph touches the y-axis.

I hope this helps!
Best wishes:)
