2(x + 4) = -5x + 1 \\ 2x + 8  =  - 5x + 1 \\ 2x + 5x = 1 - 8 \\ 7x =  - 7 \\ x =  \frac{ - 7}{7}  \\ x  =  - 1 \\  \\ check \\ 2( - 1 + 4) =  - 5 \times ( - 1) + 1 \\  - 2 + 8 = 5  + 1 \\ 6 = 6
answer is x= -1

Tan145+tan85/1-tan145*tan85 as asingle funciton
Minchanka [31]

Answer:

Step-by-step explanation:

Tan 145 = - 0.7002

Tan 85 = 11.43

Tan 145 + tan 85 =  10.7298

1 - tan(145)* tan(85) = 9.003

(Tan(145) + Tan(85)) / (9.003)

= 10.73 / 9.003

= 1.1918

I misread the question. If you mean

(Tan145+tan85) /1-tan145*tan85   (brackets are really important here)

then the answer is

Tan(145 + 85)

= Tan(230)

= 1.1918

Find the equation of a line that contains the points (−3,−1) and (−4,−7). Write the equation in slope-intercept form
BARSIC [14]

Answer:

y =6x+17

Step-by-step explanation:

First we need to find the slope

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

   = (-7- -1)/(-4 - -3)

   = (-7+1)/(-4+3)

   -6/-1

   6

The slope intercept form of the equation is

y = mx+b  where m is the slope and b is the y intercept

y = 6x+b

Substitute a point into the equation

-1 = 6(-3) +b

-1 = -18+b

Add 18 to each side

17 =b

The equation is

y =6x+17
