Answer:

The length of the shorter piece = 3 ft

The length of the longer piece = 10 ft  

Step-by-step explanation:

According to the question;

  • Total length of the string is 13 ft
  • Longer piece is 4ft longer than twice the shorter piece;

Therefore;

  • Assuming the shorter piece is x ft
  • Then, the longer piece will be (2x + 4) ft

Thus;

Longer piece + shorter piece = 13 ft

x ft + (2x + 4) ft = 13 ft

3x + 4 = 13

3x = 9

 x = 3 ft  and

2x + 4 = 10 ft

Therefore;

The length of the shorter piece = 3 ft

The length of the longer piece = 10 ft

Solve the equation. (Find only the real solutions. Enter your answers as a comma-separated list.) x4 − 8x2 + 7 = 0
ryzh [129]

Answer: x=0 or x= plus or minus 2

Step-by-step explanation:

g(x)=x^4-8x^2+7

Critical numbers are the numbers where the first derivative is zero

g'(x)=4x^3-16x+0

=4x^3-16x

g'(x)=0

Implies

4x^3-16x=0

4x(x^2-4)=0

4x=0 OR x^2-4=0

x=0 or x^2=4

x=0 or x= plus or minus 2

Find the equation of the linear function represented by the table below in slope-
maria [59]

Answer:

y=2x+1, assuming my change in the reported data was correct.

Step-by-step explanation:

The data for x had one more entry than the values for y.  I removed the second "0" so that the x and y points line up, as shown in the attached image.  The data indicate a straight line, with a slope of 2 (y increases by 2 for every x increase of 1).  The y-intercept is 1, as per the first data point (0,1).

How can you solve an equation with the variable on both sides plz help
Sergeeva-Olga [200]
I don't know if this is the right one but i hope this helps. this is how i learned it. 
step 1=get variables on one side oof the equal sign by using inverse operation (add or subtract smaller variable) 
step 2= get constants away from variable to the other side of the equal sign by using inverse operations (add or subtract constant) 
step 3: isolate the variable using inverse operation (multiply or divide)
