I believe that would be the last choice, because it is not impossible that someone without contacts or glasses would be chosen. And it is a fairly similar chance that someone with glasses or with contacts will be chosen. Hope this helps! :)

A line passes through the points (-3, 14) and (-1, 16). What is its equation in slope-intercept form?

timurjin [86]

Answer:

y = 6x + 22

General Formulas and Concepts:

Pre-Alg

Order of Operations: BPEMDAS

Algebra I

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step-by-step explanation:

Step 1: Define

Point (-3, 14)

Point (-1, 16)

Step 2: Find slope m

Substitute: $m=\frac{16-14}{-1+3}$
Subtract/Add: $m=\frac{12}{2}$
Divide: $m=6$

Step 3: Find y-intercept b

Define: y = 6x + b
Substitute: 16 = 6(-1) + b
Multiply: 16 = -6 + b
Isolate b: 22 = b
Rewrite: b = 22

Step 4: Write linear equation

y = 6x + 22

Identify each expression that represents the slope of a tangent to the curve y = 1/x+1 at any point (x,y)

a_sh-v [17]

The expressions that represent the slope of a tangent to the curve $y = \frac{1}{x+1}$ are $m = \lim_{h \to 0}\frac{\frac{1}{x + h + 1} - \frac{1}{x + 1} }{h}$ and $m = -\frac{1}{(x + 1)^{2}}$ , respectively.

<h3>How to find an expression for the slope at any point of a function</h3>

The slope at any point of the function can be found by definition of derivative following algebraic handling:

$m = \lim_{h \to 0}\frac{\frac{1}{x + h + 1} - \frac{1}{x + 1} }{h}$

$m = \lim_{h \to 0} \frac{\frac{x+1 - x - h - 1}{(x + h + 1)\cdot (x + 1)} }{h}$

$m = -\lim_{h\to 0} \frac{1}{(x + h + 1)\cdot (x + 1)}$

$m = -\frac{1}{(x + 1)^{2}}$

Thus, the expressions that represent the slope of a tangent to the curve $y = \frac{1}{x+1}$ are $m = \lim_{h \to 0}\frac{\frac{1}{x + h + 1} - \frac{1}{x + 1} }{h}$ and $m = -\frac{1}{(x + 1)^{2}}$ , respectively.

How do I graph the following set {x is an even number, -1≤x<12}

liubo4ka [24]

Step-by-step explanation:

Use this sort of layout, but where x will be an odd number, do not shade it. there should be a pattern of shaded segments followed by unshaded segments repeating
