Answer:

use own words

Step-by-step explanation:

An expression is just a mathematical phrase. In this tutorial, you'll learn about two popular types of expressions: numerical and algebraic expressions. A numerical expression contains numbers and operations. An algebraic expression is almost exactly the same except it also contains variables.

in mathematics, an algebraic expression is an expression built up from integer constants, variables, and the algebraic operations (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number)

Peyton borrowed some money from her friend in order to help buy a new video game system and agreed to pay the friend back a cons

netineya [11]

Answer:

$y=200-25x$

Step-by-step explanation:

According to the problem, the initial condition is $200. If he owed $100 after 4 weeks, that means he paid $25 per week, so that would be the constant ratio. Therefore, the expression would be:

$y=200-25x$

Where $y$ represents the amount owed, and $x$ represents weeks.

So, in the 4 week, that is, $x=4$ he owed:

$y=200-25(4)=200-100=100$

As you can observe, the relation we found first perfectly to the problem. So, the final expression that model this problem is

$y=200-25x$

What were the lengths of the legs of a right triangle in which measures 19 degrees and the hypotenuses 15 units long

Otrada [13]

Answer:

The legs of a triangle with a hypotenuse that measures 15 units long have lengths that are equal to 15 times the sine or cosine of the given angle.

leg 1 = (15 units) x (cos 19) = 14.18 units

leg 2 = (15 units) x (sin 19) = 4.88 units

The lengths of the legs are 14.18 units and 4.88 units.

Check the picture below.

so let's find the lengths of those two sides in red, since are the length and width of the rectangle.

$\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{-6}~,~\stackrel{y_1}{3})\qquad (\stackrel{x_2}{-3}~,~\stackrel{y_2}{6})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ d = \sqrt{[-3-(-6)]^2+[6-3]^2}\implies d=\sqrt{(-3+6)^2+(6-3)^2} \\\\\\ d=\sqrt{9+9}\implies \boxed{d=\sqrt{18}} \\\\[-0.35em] ~\dotfill$

$\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{-6}~,~\stackrel{y_1}{3})\qquad (\stackrel{x_2}{-2}~,~\stackrel{y_2}{-1})~\hfill d=\sqrt{[-2-(-6)]^2+[-1-3]^2} \\\\\\ d=\sqrt{(-2+6)^2+(-1-3)^2}\implies d=\sqrt{16+16}\implies \boxed{d=\sqrt{32}} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{area of the rectangle}}{(\sqrt{18})(\sqrt{32})}\implies \sqrt{18\cdot 32}\implies \sqrt{576}\implies 24$
