Answer:
(1, 7 )
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Then the equations of the 2 lines are
y = 4x + 3 → (1)
y = 6x + 1 → (2)
Substitute y = 6x + 1 into (1)
6x + 1 = 4x + 3 ( subtract 4x from both sides )
2x + 1 = 3 ( subtract 1 from both sides )
2x = 2 ( divide both sides by 2 )
x = 1
Substitute x = 1 into either of the 2 equations for corresponding value of y
Substituting into (1)
y = 4(1) + 3 = 4 + 3 = 7
Point of intersection = (1, 7 )
The answer is B. This is because we know this is 6 more than 3 times the number of students that played last year. A and C makes no sense. D does not make any sense because it is 6 more not 6 less.
<h3>The equation, when solved for x, gives the amount of money Jim earned last week is: 700 = 4x - 20</h3>
<em><u>Solution:</u></em>
Given that,
Jim earned $700 this week
This was $20 less than four times the amount he earned last week
To find: amount of money Jim earned last week
Let "x" be the amount of money Jim earned last week
From given,
Jim earnings this week = $20 less than four times the amount he earned last week
Therefore,
700 = 4x - 20
Thus the equation is found
The answer is 17.75 rupees
