The atomic number above the element is the number of protons inside of it.
That’s number 1 so answer is 169.
Number 2 is H because in the description above it states it is highly reactive

Last PreCalc Question, Need help with writing piecewise functions with graphs. Giving brainliest!

LekaFEV [45]

The piece-wise linear functions can be written as follows:

$f(x) = x, x \leq -2$ .

$f(x) = -x - 7, -2 < x \leq 1$ .

$f(x) = 2x - 9, x > 1$ .

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.

b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

For x equal or less than -2, the line passes through (-3,-3) and (-2,-2), hence the rule is:

$f(x) = x, x \leq -2$ .

For x greater than -2 up to 1, the y-intercept is of -7, and the line also passes through (1,-8), hence the rule is:

$f(x) = -x - 7, -2 < x \leq 1$ .

For x greater than 1, the function goes through (2,-5) and (3,-3), hence the slope is:

m = (-3 - (-5))(3 - 2) = 2.

The rule is:

y = 2x + b.

When x = 2, y = -5, hence:

-5 = 2(2) + b

b = -9.

Hence:

$f(x) = 2x - 9, x > 1$ .

On a coordinate plane, a line goes through (negative 3, negative 3) and (negative 1, 5).

slega [8]

Answer:

y=20

x=4

Step-by-step explanation:

Since you can plug the first 2 coordinates into the slope equation ( $\frac{y_{2}-y_{1}}{x_{2} -x_{1} }$ ) you will get 4 for the slope so for the equation for the parallel line you would get y=4x+4 and since the x=4 you could plug that in and you would get y=20 and x=4
