The area of a triangle is the amount of space on the triangle

The expression that represents the area of the triangle is $A = \frac 12|-5(2 -4) +3(2 -6) -2(4 -6)|$

The coordinates of the triangle are given as:

$R = (-5,6)$

$S = (3,4)$

$T = (-2,2)$

The area (A) of a triangle from its coordinates or vertices are:

$A = \frac 12|x_1(y_3 -y_2) +x_2(y_3 -y_1) + x_3(y_2 -y_1)|$

Substitute values for x's and y's

$A = \frac 12|-5(2 -4) +3(2 -6) -2(4 -6)|$

Hence, the expression that represents the area of the triangle is $A = \frac 12|-5(2 -4) +3(2 -6) -2(4 -6)|$

Amir has a bag of dimes and quarters. He has a total of 31 coins worth $5.20.

Step2247 [10]

Answer

B is the correct answer.

Step-by-step explanation:

This is the given information for which system of equations would be used to find out how many dimes and quarters Amir has?

x = dimes x = 0.10 or 0.1

y = quarters y = 0.25

31 coins

worth $5.20 = 5.2

x + y = 31

0.1x + 0.25y = 5.2

Write the function whose graph is the graph of y= X + 3, but is reflected about the y-axis.

attashe74 [19]

Answer:

f(x) = -x + 3

Step-by-step explanation:

To flip it over the y-axis, just make all your x-values negative.

y(x) = x + 3

f(x) = y(-x) = (-x) + 3 = -x + 3
