Answer:
Explanation:
12x = 48 - 8y
10x + 8y = 38
———————
12x + 8y = 48
10x + 8y = 38
———————
12x + 8y = 48
-1(10x + 8y = 38)
————————
12x + 8y = 48
-10x - 8y = -38
————————
2x = 10
x = 10/2 = 5
If x = 5 then:
10x + 8y = 38
10(5) + 8y = 38
50 + 8y = 38
8y = 38 - 50
8y = -12
y = -12/8
y = -3/2
Therefore, x = 5 and y = -3/2

Step-by-step explanation:
4x - 3y =5
3y = 4x - 5
y = 4/3 x - 5/3
Equation of the line passing through the point (-6,3) and parallel to L
a) Parallel lines have same slope so slope = 4/3
y - 3 = 4/3(x + 6)
y - 3 = 4/3 x + 8
y = 4/3 x + 11
Answer:
Equation y = 4/3 x + 11
b) Perpendicular lines, slope is opposite and reciprocal so slope = -3/4
y - 3 = -3/4 (x + 6)
y - 3 = -3/4 x - 4.5
y = -3/4 x - 1.5
Answer:
Equation y = -3/4 x - 1.5
total kilometers = kilometers by train + kilometers by car
265 = 80 + kilometers by car
kilometers = rate * time = 90* h
265 = 80 + 90*h
Answer: 12ft^2
Step-by-step explanation:
Since you already have the base (6ft^2), just multiply that by the height.
