To find this, just plug the numbers into the expressions.

5x = y
5(2) = 7
10 = 7
So it can't be A.

x + 2 = y
2 + 2 = 7
4 = 7

x + 4 = y
2 + 4 = 7
6 = 7

2x + 3 = y
2(2) + 3 = 7
7 = 7

The correct answer is
D. 2x + 3

11 more than four times a number is 39

Aliun [14]

Hello!

Your answer is: 7

(X = "<em>A number</em>")

<em>"11 more than four times a number is 39"</em> in equation form is: 4X + 11 = 39

to solve, first subtract 11 from both sides:

4X = 28

then divide both sides by 4 to get:

X = 7

I hope this helps, and have a nice day!

1. Find the area of the region bounded above by y = e^x, bounded below by y = x, and bounded on the sides

salantis [7]

The area of the region bounded above by y= eˣ bounded by y = x, and bounded on the sides; x =0; and x = 1 is given as e¹ - 1.5.

<h3>What is the significance of "Area under the curve"?</h3>

This is the condition in which one process increases a quantity at a certain rate and another process decreases the same quantity at the same rate, and the "area" (actually the integral of the difference between those two rates integrated over a given period of time) is the accumulated effect of those two processes.

<h3>What is the justification for the above answer?</h3>

Area = $\int\limits^1_0 {(e^x-x)} \, dx$
