L=3w-4

Perimeter = 64

64=2L+2w

Plug in L that we solved above into this equation:

64=2(3w-4)+2w

64=6w-8+2w

64=8w-8

72=8w

w=9

Plug W back into the equation above to solve for L

L=3w-4

L=(3)(9)-4

L=23

Check the answer with the perimeter formula:

P=2L+2w

P=2(23)+2(9)

P=46+18

P=64

The function f is defined by f(x)=5x+k, where k is a constant. Find k, if the value of f at x=2 is equal to 14.
yKpoI14uk [10]

Answer:

k = 4

Step-by-step explanation:

f(x)=5x+k

Let x =2

f(2) = 5*2 +k

f(2) = 10+k

We know f(2) = 14

14 = 10+k

Subtract 10 from each side

14-10 = 10+k-10

4 =k

hammer [34]

Answer:

x = 4

Step-by-step explanation:

12x + 5 = 4x + 37, first subtract both sides by 5 and subtract both sides by 4x

8x = 32, next divide 8 from both sides

x = 4

Rearrange the equation so nnn is the independent variable.<br> m+1=-2(n+6)m+1=−2(n+6)
lapo4ka [179]

Answer:

m=-2n-13

Step-by-step explanation:

The given equation is m+1=-2(n+6)

We want to rearrange this equation so that, n becomes the  independent variable.

This means we must solve form, m which becomes the dependent variable.

We expand the parenthesis to get:

m+1=-2n-12

We now subtract 1 from both sides to obtain:

m=-2n-12-1

We simplify to obtain:

m=-2n-13

This can be rewritten as

m(n)=-2n-13
