Just do 7 total hours minus the 2.6 hours he needs left to complete the 7 hours. ezpz
It’s the second one I think
The answer is B. 15
The graph is going up by 3 every time therefore 12+3=15 hope this helps :)
Explanation just use gauth.math
Hope this helps
Answer:
domain represents the x values so for example in a diagonal line that continues infinitely, the domain is all real numbers or (-infinity, infinity)
range represents y values so it would also be all real numbers or (-infinity, infinity)
let’s say there is a line (refer to pic) that moves ONLY from point (-3, -1) and (2, 2)
the domain would be [-3, 2]
we use brackets because it’s a real number unlike infinity (also because it’s a closed circle on the graph; if the graph had an open circle you would use a parenthesis)
and the range would be [-1, 2]
if you have any more questions about this explanation feel free to ask!
