Answer:

x = -6.

Step-by-step explanation:

8x - 3 = -9 + 7x. Add 3 to both sides. 8x = -6 + 7x. Subtract 7x from both sides. x = -6.

You can substitute to check your answer. 8(-6) - 3 = -9 + 7(-6). -48 - 3 = -9 + -42. -51 = -51.

How to make a linear equation perpendicular?
algol [13]
The slopes of 2 perpendicular lines with be reciprocals with the opposite sign.
For example if you have the equation y=-5x+2, your slope is -5. In a line perpendicular to y=-5x+2, your slope would be 1/5. As for finding b in y=mx+b for your second equation, I would need more specific information.

Hope it helps!

A company manufacturing oil seals wants to establish X and R control charts on the process. There are 25 preliminary samples of
alisha [4.7K]

Answer:

A ) i) X control chart : upper limit = 50.475, lower limit = 49.825

    ii) R control chart : upper limit =  1.191, lower limit = 0

Step-by-step explanation:

A) Finding the control limits

grand sample mean = 1253.75 / 25 = 50.15

mean range = 14.08 / 25 = 0.5632

Based on  X control CHART

The upper control limit ( UCL ) =

grand sample mean + A2* mean range ) = 50.15 + 0.577(0.5632) = 50.475

The lower control limit (LCL)=

grand sample mean - A2 *  mean range = 50.15 - 0.577(0.5632) = 49.825

Based on  R control charts

The upper limit = D4 * mean range = 2.114 * 0.5632 = 1.191

The lower control limit = D3 * mean range = 0 * 0.5632 = 0  

B) estimate the process mean and standard deviation

estimated process mean = 50.15 = grand sample mean

standard deviation = mean range / d2  = 0.5632 / 2.326 = 0.2421

note d2 is obtained from control table

nikklg [1K]

To shift vertically the graph of the function f(x), you have to add a constant to its expression:

f(x) \to f(x)+k

If k is positive, you shift the function k units above, if k in negative, you shift the function k units below.

So, if you want to shift the graph of f(x)=45x+20 two units down, you have to subtract 2 (i.e., add -2):

f(x) = 45x+20 \to 45x+20-2 = 45x+18
