The correct point of the graph would be B. (2,-5)
Answer:
The time to complete the job is given by the expression below:
Where T = time it takes to wash all the windows
x = the number of workers assigned to the job
Step-by-step explanation:
The proportionality can be represented below as:
T ∝
T = -------------------- Equation 1
Where K is the constant of proportionality
Considering the given instance,
When T = 6, x = 4
6 =
K = 4 × 6
K = 24
Substituting the value of K into Equation 1,
T =
So a triangle angles must add up to 180. You would subtract 180 by the two known angle which are 90 and 30. Then if you subtract them you would get 60. The final answer is 60
Answer:
see below
Step-by-step explanation:
Since 2x appears on the left side of both equations, that term can be eliminated by subtraction, which is what the first choice suggests.
The result will be ...
3y = 7 -4y +5 . . . . . . . . . second equation subtracted from the first
7y = 12 . . . . . . add 4y
y = 12/7 . . . . . . divide by 7
__
However, the fact that 2x is by itself on the left side of the second equation suggest that <em>substitution</em> may also be a good option. Perhaps an equally good first step is to use the expression in the second equation to substitute for 2x in the first:
(4y -5) +3y = 7
Either way, the resulting equation is 2-step.
7y = 12 . . . add 5
y = 12/7 . . . divide by 7
___
The other suggested "first steps" do nothing useful.
3.92 rounded to the nearest tenth should be 4.00 or 4, sorry if I’m wrong, have a good rest of your day/night
