Answer:

(-3,4)

Step-by-step explanation:

Y - 4 = -2(x + 3)

Let x = -3

Y - 4 = -2(-3 + 3)

Y - 4 = -2(0)

Y -4 =0

Add 4 to each side

Y -4+4 =0+4

Y= 4

-24-(-6)+(-31) step by step be sure to simplify first

trasher [3.6K]

Answer:

-49

Step-by-step explanation:

rule of thumb: whenever you have two negatives, they equal a positive! when you have one negative and one positive, it is a negative!

let's start by going from left to right :))
-24 -(-6) + (-31)
-(-6) is actually + 6!
-24 + 6 + (-31)
+(-31) would be -31 because one - and one + is a -
-24 + 6 - 31
-18 - 31
-49

Step-by-step explanation:

The Google calculator will reliably use PEMDAS to evaluate an expression.

= (2.1 +30.36)×0.8

= 32.46×0.8

= 25.968

Let the number of green apples and red apples be 8x and 3x respectively.

Given: 8x-3x =35

=> 5x =35 => x=7

Hence there are 8x=56 green apples and 3x=21 red apples.Ans.

The hypotenuese of an isosceles right triangle is 13 inches. The midpoints of its sides are connected to form an inscribed trian

Georgia [21]

Answer:

The Sum of the areas of theses triangles is 169/3.

Step-by-step explanation:

Consider the provided information.

The hypotenuse of an isosceles right triangle is 13 inches.

Therefore,

$x^2+x^2=169\\2x^2=169\\x=\frac{13}{\sqrt{2} }$

Then the area of isosceles right triangle will be: $A=\frac{1}{2} x^2$

Therefore the area is: $A=\frac{169}{4}$

It is given that sum of the area of these triangles if this process is continued infinitely.

We can find the sum of the area using infinite geometric series formula.

$S=\frac{a}{1-r}$

Substitute $a=\frac{169}{4} \ and\ r=\frac{1}{4}$ in above formula.

$S=\frac{\frac{169}{4}}{1-\frac{1}{4}}$

$S=\frac{\frac{169}{4}}{\frac{3}{4}}$

$S=\frac{169}{3}$

Hence, the Sum of the areas of theses triangles is 169/3.
