Find x for 5x+5+65+65=

Mathematics
1 answer:
Phoenix [80]4 years ago
4 0

5x+5+65+65=

Answer:

x=-27

Step-by-step explanation:

We want to find x right, so everything that does not have x you can move to the other side. 5x=-5-65-65. So that should be your equation so far. Now we know that when there are two negatives it is a negative and you add so -5-65=-70-65=-135. So your equation now should be: 5x=-135. Now we can divide -135 with 5 which gives us... -27! There’s your answer. Hope this was correct!

What is the slope of the line that passes through the pair of points? (5,2) and (7,8) the answers are 2/3,-2/3,3/2 or -3/2
Mice21 [21]
Answer:  The slope is:  "3" ; which does not appear among the                                   answer choices given.
______________________________________________

The slope, "m" is calculated as follows:
___________________________________
Given two coordinates on a line; 

m = (y₂ − y₁) / (x₂ − x₁) ;
__________________________________________

We are given the following 2 (TWO) coordinates:
__________________________________________
 1)  (5,2) ; which is:  (x₁ ,y₁) ;  so x₁ = 5 ; y₁ = 2 ; AND:
 
 2)  (7,8);  which is:  (x₂ ,y₂) ;  so x₂ = 7; y₂ = 8 ;
_____________________________________________
So;  m = (y₂ − y₁) / (x₂ − x₁) = (8−2) /.(7−5) = 6/2 = 3 .

m = 3.  The slope is: 3 ; which does not appear among the answer choices given.
______________________________________________
Alternately,
______________________________________________
We are given the following 2 (TWO) coordinates:
__________________________________________
 1)  (7,8) ; which is:  (x₁ ,y₁) ;  so x₁ = 7 ; y₁ = 8 ; AND:
 
 2)  (5,2);  which is:  (x₂ ,y₂) ;  so x₂ = 5; y₂ = 2 ;
______________________________________________
So;  m = (y₂ − y₁) / (x₂ − x₁) = (2−8) / (5−7) = -6/-2 = 3 .

m = 3.  The slope is 3 ; which does not appear among the answer choices given.

Which equation is quadratic in form?
Drupady [299]

we know that

A quadratic equation is a polynomial with an order of two. Its general form is

ax^{2} + bx + c = 0

case a) 6(x + 2)^{2} + 8x + 2 + 1 = 0

6(x + 2)^{2} + 8x + 2 + 1 = 0 \\ 6(x^{2} +4x+4)+8x+3=0\\ 6x^{2} +24x+24+8x+3=0\\ 6x^{2} +32x+27=0\\\\ a=6\\  b=32\\ c=27

<u>The case a) is a quadratic equation</u>

case b) 6x^{4} + 7x^{2} - 3 = 0

<u>The case b) is a grade 4 polynomial</u>

case c) 5x^{6} + x^{4} + 12 = 0

<u>The case c) is a grade 6 polynomial</u>

case d) x^{9} + x^{3} - 10 = 0

<u>The case d) is a grade 9 polynomial</u>

therefore

the answer is

6(x + 2)^{2} + 8x + 2 + 1 = 0

PLEASE HELP AND KNOW YOU ARE CORRECT BEFORE ANSWERING PLEASE AND THANK YOU.
swat32

Answer:

Both are false

Step-by-step explanation:

B is 3 units below P

After dilation B' will be 5 units below P so cannot be on the same horizontal line.

similarly segment CD is 3 units long,

After dilation segment C'D' will be 5 units long so is not equal to segment CD.
