Answer:

Step-by-step explanation:

we have to find if the series have a constant of proportionality by dividing the value of y by each value of x

1)

100 : 2 = 50

200 : 4 = 50

300 : 6 = 50

400 : 8 = 50

ok = y

2)

0.60 : 4 = 0.15

1.20 : 8 = 0.15

1.44 : 12 = 0.12

no = n

3)

0.15 : 1 = 0.15

0.3 : 2 = 0.15

0.45 : 3 = 0.15

0.6 : 4 = 0.15

ok = y

HELP, I NEED HALP ASAP <br> 180=x+(3x-8)
jok3333 [9.3K]

Answer:

x=47

Step-by-step explanation:

Let's solve your equation step-by-step.

180=x+3x−8

Step 1: Simplify both sides of the equation.

180=x+3x−8

180=x+3x+−8

180=(x+3x)+(−8)(Combine Like Terms)

180=4x+−8

180=4x−8

Step 2: Flip the equation.

4x−8=180

Step 3: Add 8 to both sides.

4x−8+8=180+8

4x=188

Step 4: Divide both sides by 4.

4x4=1884

x=47

What is the multiple zero and multiplicity of f(x)=x^3-8x^2+16x?
lions [1.4K]
Multiplicity is how many times a root repeats
factor
x(x²-8x+16)
what times wat =16 and adds to -8
-4 and -4
x(x-4)(x-4)
x(x-4)²
set to zero
x=0

x-4=0
x=4

roots are 0 ad 4

4 repeats 2 times, so has a multiplicty of 2


so
roots are 0, and 4 multiplicity 2
