Answer:

Sample Response: First, decide what the variable will represent. For example, you might let d represent “days in the marking period”. Next, decide what the constant will represent. For example, 120 could be “120 days”. Use the inequality symbol to determine the relationship between the variable and the constant. An example might be, “There are fewer than 120 days in the marking period.”

We know that

$\sf Slope=\dfrac{y_2-y_1}{x_2-x_1}$

Slope = -4 - 5/-2 - 1

Slope = -9/-3

Slope = 3/1

Slope = 3

Hence,

Slope is 3

Find the estimates of x^2-x-2=3

Julli [10]

Answer:

$x=\frac{1+\sqrt{21}}{2}\approx 2.79\\or\ x=\frac{1-\sqrt{21}}{2}\approx -1.79$

Step-by-step explanation:

Given

Quadratic equation is

$x^2-x-2=3\\x^2-x-5=0$

Roots of the quadratic equation $ax^2+bx+c=0$ are

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\$

So, for the given equation roots are

$x=\frac{1\pm\sqrt{(-1)^2-4(1)(-5)}}{2\cdot 1}\\x=\frac{1\pm\sqrt{21}}{2}\\so, x=\frac{1+\sqrt{21}}{2}\approx 2.79\\or\ x=\frac{1-\sqrt{21}}{2}\approx -1.79$

Homer mowed 5 lawns in his first month and increased the number he mows by two for each month following. Which of the following

ser-zykov [4K]

The equation which represent the interpretation of the scenario is 5 + 2x

<h3>Algebra</h3>

Number of lawns Homer mowed = 5
Additional laws mowed each month = 2
Number of months = x

Total laws mowed = Number of lawns Homer mowed + (Additional laws mowed each month × Number of months)

= 5 + (2 × x)

= 5 + 2x
