Does #7 look right? Im struggling on this

Answer:

-5

Step-by-step explanation:

We can use the slope formula to find the slope

m = ( y2-y1)/(x2-x1)

     =(-12 -8)/(3 - -1)

    =(-12-8)/(3+1)

   = -20/4

   = -5

Answer:

[tex]\displaystyle [-1, 2][/tex]

Step-by-step explanation:

[tex]\displaystyle -2x + [1 - x] = 4 → 4 = 1 - 3x → \frac{3}{3} = \frac{-3x}{3}; -1 = x, 2 = y \\ \\ [-1, 2][/tex]

Answer:

1) (7 X 6) = 2 [{45 - 3(7 X 2 - 15 + 6)} + 4]

or,42=2[{45-3(14-15+6)}+4]

or,42=2[{45-3(14-21)}+4]

or,42=2[{45-3X(-7)}+4]

or,42=2[45+21}+4]

or,42=2X70

:42=140

The equation after simplification is [tex]7x^{6}+42x^{2} -152=0[/tex].

Simplification of an equation is the process of writing an equation in the most efficient and compact form without affecting the value of the original equation. It involves, multiply out the brackets and then simplify the resulting equation by collecting the like terms.

For the given situation,

The equation is

[tex]7x^{6}=2[{45-3(7x^{2} -15+6)}+4][/tex]

⇒ [tex]7x^{6}=2[{45-3(7x^{2} -9)}+4][/tex]

⇒ [tex]7x^{6}=2[{45-21x^{2} +27}+4][/tex]

⇒ [tex]7x^{6}=2[-21x^{2} +76][/tex]

⇒ [tex]7x^{6}=-42x^{2} +152[/tex]

⇒ [tex]7x^{6}+42x^{2} -152=0[/tex]

Hence we can conclude that the simplified equation is [tex]7x^{6}+42x^{2} -152=0[/tex].

QR= 8

Hope it helps.

Answer: PQ = 12

QR = 8

Step-by-step explanation:

3x + 6 + 2x+4 = 20

5x = 20- 10

so, x = 2

so

PQ = 3x + 6 = 3*2+6 = 6+6 = 12

QR = 2x+4 = 2*2+4 = 4+4 = 8

Step-by-step explanation:

First you divide the number of clicks by seconds.

36÷5=7.2

26÷3=8.6

Now you know how much clicks the bots do in 1 second

Bot#3= 7.2

Bot#4= 8.6

Now multiply by 10.

Bot#3= 72

Bot#4= 86

Bot#4 does more clicks in 10 seconds.
