I think so. But, the only way you can simplify is is if you add the like terms, in this case, -4x and -11x. #1 will simplify to -15x=36. you cannot simplify the other one any further. <span />

What is the solution to the equation 7(a – 10) = 13 – 2(2a 3)?
geniusboy [140]
7(a - 10) = 13 - 2(2a + 3)
7a - 70 = 13 - 4a - 6 = 7 - 4a
7a + 4a = 7 + 70
11a = 77
a = 77/11 = 7
a = 7.

Consider the equation y= -2x -3.
Alona [7]

Part A

The graph is shown below as an attached image.

The diagram shows a straight line that goes through the two points (0,-3) and (1, -5)

I'm using GeoGebra to graph the line.

side note: (0, -3) is the y intercept which is where the graph crosses the y axis.

==================================================

Part B

Answer is choice 2

The graph can be written in the form y = mx+b, so it is linear

In this case, m = -2 is the slope and b = -3 is the y intercept

We can write the slope as m = -2 = -2/1. This tells us that we can move down 2 units and then over to the right 1 units to get from point to point. This process of "down 2, over to the right 1" happens when moving from point A to point B in the diagram below.

Please help! I’m in a test rn! If f(x) and g(x) are inverse functions of each other, which of the following statements is true?
White raven [17]

Answer:

D) (g\cdot f)(x)=x

Step-by-step explanation:

If two functions f(x) and g(x) are inverse of each other, then the following conditions must be true:

i. (f\cdot g)(x)=x

ii. (g\cdot f)(x)=x

Therefore, out of the four choices available, only option D matches the condition for inverse function to exist.

Therefore, (g\cdot f)(x)=x
