Answer:
5.5
Step-by-step explanation:
The y-intercept of the line graph shown above is the value of the point where the line cuts the y-axis. The y-intercept of this graph is between 5 and 6. However, we can get an accurate value by calculation. This can be done by generating an equation of the line.
Recall the slope-intercept equation, 
, where m = slope of the line, b = y-intercept.
To generate the equation of the line, first find slope using the points (-2, 7) and (6, 1):
.
Substitute m = ¾ and the coordinates (6, 1) into the slope-intercept equation to find the y-intercept (b):
Therefore, b = y-intercept = 5.5.
To generate the equation of the line, plug in the values of m and b, we would have:
y = ¾x + 5.5
The y-intercept of the line of the graph is 5.5.
Answer:
28/3
Step-by-step explanation:
Answer:
The point (0, 25) is not a solution, but the point (-4, 10) is a solution.
Step-by-step explanation:
You can graph the inequality and check. The first point (0, 25) is on the boundary line, but that line is NOT part of the solution set. The second point (-4, 10) is well inside the solution space.
(0, 25) is not a solution
(-4, 10) is a solution
_____
You can put the values into the inequality and see if a true statement results.
-10(0) +(25) > 25 . . . . False
-10(-4) +(10) > 25 . . . . true
The first point is NOT a solution; the second point IS a solution.
Answer:
($30s+g)
Step-by-step explanation:
If a caterer offers a package that feeds up to 50 people for $1,500, the amount of packaged that fed one person will be $1500/50 which is $30.
If there is an additional charge of $24.75 on each person, the total amount spent on each person will be $50+$24.75 which is $74.75.
The linear model that represent total amount charge per host s as a function of additional guest will be $30s+g since a person spent $30 plus additional charge of 'g'
It's the water
The salt would be the solute that dissolves in the solvent.
Temp - is a factor
(affecting rate at which salt dissolves)
grams - unit of measure
Hope this helps!
