Which statement is true?

kvasek [131]

Answer:

A. The slope of Function A is greater than the slope of Function B.

Step-by-step explanation:

The slope of a function can be defined as rise/run. In Function A, the rise/run is 4. The slope in Function B is much easier to see: it is 2. Because 4 is greater than 2, Function A has a greater slope than Function B.

Roman solved the equation 5a+2b=10 for a. His steps are shown below. 1. Subtract 2b: 5a+2b-2b=10-2b 2. Multiply by 5: 5a+10-2b W

Answer:

In step 2, he needed to divide both sides of the equation by 5

Step-by-step explanation:

we have

$5a+2b=10$

Solve for a------> That means isolate the variable "a"

step 1

Subtract 2b to both sides

$5a+2b-2b=10-2b$

$5a=10-2b$

step 2

Divide by 5 both sides

$5a/5=(10-2b)/5$

$a=(10-2b)/5$

Step-by-step explanation:

<u>Linear Combination Of Vectors </u>

One vector $\vec b$ is a linear combination of $\vec a_1$ and $\vec a_2$ if there are two scalars $x_1, x_2$ such as

$\vec b=x_1\vec a_1+x_2\vec a_2$

In our case, all the vectors are given in $R^3$ but there are only two possible components for the linear combination. This indicates that only two conditions can be used to determine both scalars, and the other condition must be satisfied once the scalars are found.
