Consider the ordered pairs (1, 4), (–1, 2), and (0, 3). Which of the four equations below could have been used to generate these

ollegr [7]

The equation of the ordered pairs (1, 4), (–1, 2), and (0, 3) is y = x + 3

<h3>How to determine the equation?</h3>

The ordered pairs are given as:

(1, 4), (–1, 2), and (0, 3)

From the above ordered pairs, we can see that the difference between the x and y values is 3.

This means that:

y - x = 3

Add 3 to both sides

y = x + 3

Hence, the equation of the ordered pairs (1, 4), (–1, 2), and (0, 3) is y = x + 3

What is the answer to –(d+1)>3

aleksandrvk [35]

Answer:

−(d+1)>3

Step 1: Simplify both sides of the inequality.

−d−1>3

Step 2: Add 1 to both sides.

−d−1+1>3+1

−d>4

Step 3: Divide both sides by -1.

$\frac{-d}{-1}$ > $\frac{4}{-1}$

d < -4

Write an equation and solve. Round to the nearest hundredth where necessary. 19 is what percent of 40?

snow_lady [41]

You first divide 40 by 19:

19/40=?

Then you convert that to percentage by dropping the decimal point and attaching a %

(hint: you should get 48% about :)

Question 20 of 21

RoseWind [281]

Answer: A. (0,2)

Y-Intercept - (0,2)

No X-Intercept.

Step-by-step explanation: f(x)=2*3 is a horizontal line to the x-axis, which means that the y-intercept is (0,2) and is no x-intercept.

Hope this helps you out! ☺
