Step-by-step explanation:
hope this helped :)
Well I think I can help you out ...
if you assume input x=2
the output will be as following :
y= -1/3(2)+2
=-2/3+2
=-2/3+6/3
=(-2+6)/3
=4/3
=1.333
The first one because you distribute -1
Answer:
y-5=3(x-1)
Step-by-step explanation:
- The graph shows an equation y=a+bx, that has an intercept "a", in a=2 (value of y when x=0), and a slope "b", b=3 (to see the slope, watch the change in y when x changes a unit, remembering that each square in the graph represents a unit - for example, when y=2, a change on x, from x=0 to x=1 would result in y=6).
- Then, to know wich of the equations presented is the one that represent the graph, we should search that equation that meets the following requirements: <u>intercept a=2 and slope b=3</u>.
- The first expression can be rewrite as follows: y=6-13x (to arrive to this expression, we apply distributive property in the right ide of the equation, and then we sum 4 both sides of the equation). This equation does not meet our requirements.
- The second expression can be rewrite as follows: y=4+13x (we apply the same steps than we apply in the previous example). Again, this equation does not meet the requirements (intercept a=2 and slope b=3).
- The third expression can be rewrite as follows: y=1-3x (to arrive to this expression, we apply distributive property on the right side of the equation, and then we subtract 2 both sides of the equation. This expression does not meet the requirements either.
- Finally, the last equation can be rewrite like y=2+3x (to arrive to this expressionn, we apply distributive property in thesecond side of the equation, and then we add 5 both sides of the equation. This expression actually meet the requirements! It has an intercept equal to 2 and its slope is 3.
3 moer than (3+) 2 times the numbe of books he sold in the second week (2 times second week)
first week=3+(2 time 2nd week)
total ie sold 18
so
first week+second week=18
3+(2 times 2nd week)+2nd week=18
solve
minus 3 both sides
3-3+(2 times 2nd week)+2nd week=18-3
0+(2 times 2nd week)+2nd week=15
(2 times 2nd week)+2nd week=15
add
3 times 2nd week=15
divide both sides by 3
2nd week=5
sub back
first week+second week=18
first week+5=18
minus 5
first week=13
he sold 13 in the first week
