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

Solve the quadratic equation by using a numeric approach.
Sonja [21]

The solution to the quadratic equation by using a numeric approach

are x = 6.3 and x = -31.3

Given the quadratic function expressed as;

0.02x²+ 0.5x - 4 = 0

Multiply through by 100 to have;

2x² + 50x - 400 = 0

Using the general formula to solve:

x = -50±√2500-4(2)(-400)/2(2)

x = -50±√2500+3200/4

x = -50±75.49/4

x = -31.3 or 6.3

Hence the solution to the quadratic equation by using a numeric approach

are x = 6.3 and x = -31.3

What is an equation in point slope form of the line that passes through (7, 1) and (-3,9)
LuckyWell [14K]

Answer:

y= -4/5x+33/5

Step-by-step explanation:

for questions like these, the slope is always defined as the change in y over the change in x or use the equation m=y2-y1/x2-x1.

x1=7 and y1=1

x2=-3 and y2=9

now plug these numbers in to the equation. m= 9-1 / -3-7 Or m= 8/-10 simplified to m= -4/5

now that we have the slope you can plug it in to the equation y=mx+b and get y= -4/5 + b.

to find b, the y-intercept, you can use either of the two points and the answer will be the same. for this one, I'll use (7,1).

1= -4/5 x 7+b. b= 33/5

HOPE THIS HELPS!!

Which number could replace the to make this number sentence true? 27 &gt; + 8
Inessa [10]
Using a sample inequality, take 35> ? + 3. Making that ?=x, we have 35 > x+3. Subtracting 3 from both sides, we get 32 > x. Therefore, as long as 32 is greater than x, any value replacing x is fine.

I challenge you to apply this strategy to this problem! Good luck, and feel free to ask with any questions!
