<u>Equation of the Line</u>
A line of slope m and y-intercept b can be expressed by the equation:
The given line has the equation:
Let's express it in the correct form:
Dividing by -4
The slope of this line is m1=2. To find the slope m2 of a line perpendicular to this one, we use the following equation:
Solving for m2:
The required equation has the form:
To find b, we use the point (3,4) through which the line passes:
Thus the equation of the line is:
Answer:
x + 2
Step-by-step explanation:
Replace the x with y.
Making is x = y -2
Solve for x=y-2
and you get x+2
Answer:
You can use the method of substitution.
Let the advance and same-day tickets be x and y respectively.
x + y = $70 ---> (1)
25x + 35y = $2050 ---> (2)
From Statement (1):
Let (1) × 25
25x + 25y = $1750
10y = $2050 - $1750
= $300
y = $300 ÷ 10
= $30 ---> (3)
From Statement (3):
Substitute (3) into (1)
x + $30 = $70
x = $70 - $30
= $40
Advance ticket: $40
Same-day ticket: $30
Answer:
114cm
Step-by-step explanation:
3×8×4=96
3×3×2=18
96+18=114
