Answer:
S = 20h + 3
Step-by-step explanation:
It is seen in a political science class that the test score were determined to be 20 times the number of hours, h, the student studied plus 3.
Hence, the condition can be modeled by the equation
S = 20h + 3
where, S represents the score of a particular student who studied h hours before the test. (Answer)
3m+5
Josh’s marbles can be represented by m
Matthew’s marbles can be represent by 3m+5 (the 3m is for triple what Josh has which is m)
Answer:
Slope -1, y intercept +5.
Bold line, shaded above
Step-by-step explanation:
x + y - 5 ≥ 0
y ≥ -x + 5
Let's call the three numbers x, y, and z.
The numbers are 3, 12, and 5.
x + y + z = 20
y = 4x
x + z = 8
We can rewrite the first equation because y is 4x, so
x + 4x + z = 20
5x + z = 20
And now we can use simultaneous equation rules to solve
5x + z = 20
x + z = 8
5x + z = 20
5x + 5z = 40
(subtract)
-4z + -20
÷ -4
z = 5
x + z = 8
x + 5 = 8
x = 3
y = 4x
y = 4 × 3
y = 12
