11. D(-2, 3), E(5, 5), F(-4, 10)
Find the measures of the sides of DEF,then classify it by its sides

Answers

Answer 1

Answer:

Step-by-step explanation:

Given the coordinates D(-2, 3), E(5, 5), F(-4, 10), to find the measure of the sides, we will use the formula for calculating the distance between 2 points as shown:

D = √(y2-y1)²+(x2-x1)²

For DE;

D(-2, 3), E(5, 5),

DE = √(5-3)²+(5-(-2))²

DE = √2)²+7²

DE = √4+49

DE = √53

For DF;

D(-2, 3), F(-4, 10)

DF = √(10-3)²+(-4-(-2))²

DF = √7²+(-2)²

DF = √49+4

DF = √53

For EF;

E(5, 5) F(-4, 10)

EF = √(10-5)²+(-4-5)²

EF = √5²+(-9)²

EF = √25+81

EF = √106

Since two he sides DE and DF are equal, this shows that the triangle is an isosceles triangle. An isosceles triangle  is a triangle that has two of its sides and angle equal

Which of the following rules could represent the function shown in the table?
f(x) = -2x
f(x) = 2x-1
f(x) = 2x+1

Answers

Answer: f(x) = 2x+1

Step-by-step explanation: Substitute the variable with the “x” values in the chart to check your answers.

1. f(x) = 2x+1

Add in the “x” value

f(x) = 2x(-1) or 2 multiplied by -1

f(x) = -2 + 1

If the answer is equal to your “y” value , it can represent the function.

the answer is 7(13a+4c)

ind the GCF of 91 and 28 since a and c are separate variables. this is 7; since 91/7 is 13 and 28/7 is 4. we can take this out of the parentheses like this:

7(13a+4c)

Answer:

7(13a+4c)

Step-by-step explanation:

hi! let's find the GCF of 91 and 28 since a and c are separate variables. this is 7, since 91/7 is 13 and 28/7 is 4. we can take this out of the parentheses like this:

7(13a+4c)

this is basically like reverse distribution. if you distribute the 7 into the parentheses, you will get the original unfactored expression.

no solution

Step-by-step explanation:

-21*(16-2y)/7-6y=24

-3(16-2y)-6y

-48+6y-6y=24

-48=24

There is no solution for given system of equations.

System of equations :

Another equation is, [tex]-21x-6y=24[/tex]

Substitute value of x in above equation.
