Answer:
The reciprocal of -7/9 is -9/7
Step-by-step explanation:
A reciprocal of a number is the multiplicative inverse of said number. In other words,
The reciprocal of x/y is y/x
Therefore, the reciprocal of -7/9 is -9/7
Answer:
(2x+3)(x−4)
Step-by-step explanation:
Factor 2x2−5x−12
2x2−5x−12
=(2x+3)(x−4)
Answer:
(2x+3)(x−4)
Answer:
The 32 electricians are expected to finish the job in 27 days.
Step-by-step explanation:
In this case we can apply a rule of three to calculate the time it'll take for the 32 electricians to finish the job. This is done below:
24 electricians -> 36 days
32 electricians -> x days
We have to be careful here, since the variables are inversely proportional, since if there are more electricians working on the same job, we expect the job to be finished in fewer days, therefore we need to invert one of the fractions as shown below:
The 32 electricians are expected to finish the job in 27 days.
Answer:
- D. y + 10 = 1/8* (x + 32)
Step-by-step explanation:
Use the given points to work out the equation of the line.
<u>Find the slope:</u>
- m = (- 10 - (-4)) / (- 32 - 16) = - 6 / - 48 = 1/8
<u>Use (-32, - 10) and point- slope form:</u>
- y - (- 10) = 1/8*(x - (-32))
- y + 10 = 1/8* (x + 32)
Correct choice is D
What sort of question is that lol
