Evaluate the function for h(1) <br><br> h(x) = |1 – 7x|

daser333 [38]

Answer:

We conclude that:

$h\left(1\right)=6$

Step-by-step explanation:

Given

The function is

$h\left(x\right)\:=\:|1\:-\:7x|$

To determine

h(1) = ?

Given the function

$h\left(x\right)\:=\:|1\:-\:7x|$

substitute x = 1 in the function

$h\left(1\right)=\left|1-7\left(1\right)\right|$

$h(1)=\left|1-7\right|$

$h(1)=\left|-6\right|$

Apply absolute rule: |-a| = a

$h\left(1\right)=6$

Therefore, we conclude that:

$h\left(1\right)=6$

Abdullah earns $10 an hour delivering newspapers on his bicycle . He started with $20 in his bank account. what is the rate and

elixir [45]

Explanation:

The equation for this problem can be modeled in y = mx + b form.

m represents the rate of change and b represents the initial value or constant.

y = 10x + 20

x represents the number of hours he spent delivering newspapers

y is his total money after whatever number of hours he worked

The rate is 10, because it determines how much money he earns for each hour.

The y-intercept is 20, representing the starting amount of money in his bank account.

Answer:

2) (-∞, 17]

Step-by-step explanation:

The leading coefficient of the function is negative, so the parabola opens downward. The vertex will be a maximum, the upper end of the range. The lower end of the range will be -∞.

The vertex of the function lies on the axis of symmetry. The maximum can be found by evaluating the function at x=-4.

y = -(-4)² -8(-4) +1 = -16 +32 +1 = 17

The range of the function is (-∞, 17].
