7x = 2(x - 50)

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Distribute 2:                    7x = 2x - 100
  2. Isolate <em>x </em>term:                 5x = -100
  3. Isolate <em>x</em>:                          x = -20

Answer:

x= -20

Step-by-step explanation:

So the first thing you would want to do is multiply 2 on both x and -50. After that you will end up with 7x = 2x - 100. Then you will need to subtract x on both sides getting 5x = -100. Finally you will need to divide 5 on both sides getting x = -20

What are the slope and the y-intercept of the linear function that is represented by the equation y=-10x+1?
Alenkasestr [34]
Linear functions can be written in the form y=mx+b, where:
y is a y coordinate on the line
m is the slope of the line
x is the x coordinate on the line that corresponds with the y coordinate in the equation
b is the y-intercept of the line

So for the equation y=-10x+1:
m=-10 and b=1 so the slope of the line is -10, and the y-intercept is 1. Your answer is B.

Which equation is correct? cot x° = opposite ÷ adjacent sec x° = opposite ÷ adjacent sec x° = adjacent ÷ opposite cot x° = adjac
Ilya [14]
Sec  x and cot x are the reciprocals of cos x and tan x  respectively.

So, for example,  cos x = adj / hyp,  so sec x = hyp / adj

The last choice is the correct one  because tan x  = opp / adj  so cot  = adj / opp.
