Answer:

First convert them which will be

-7/5 - (-4/5)

so when you subtract a negative number from negative number they actually subtract ex = -4-(-2) = -2

so its simply 7/5-4/5 then add a negative sign

so

3/5

now add negative sign so

-3/5

Answer:

a) 21m - 0.87 = m

b) m = 0.0435 mg

21(0.0435) - 0.87 = 0.0435

0.9135 - 0.87 = 0.0435

0.0435 = 0.0435

True statement, so correct

c) 21m - 0.87 = m

20m = 0.87

m = 0.87/20

m = 0.0435 mg

Which of the following is equivalent to y-4=1/2(x-6)
Talja [164]

Answer:

B

Step-by-step explanation:

If we reorder the equation in a certain way then it will look like this:

y-4=1/2(x-6)

y-4=1/2x-3

y-1=1/2x

y=1/2x+1

therefore B is correct since we reduced the equation to y=1/2x+1.

It may be hard to understand but the question is basically asking which one of these answers is equal to y.

Hope this helped you and let me know if i messed up or if im correct so i can imporve from my mistakes
