Answer:
parallel line slop2 = -5/4
perpendicular line slope = 4/5
Step-by-step explanation:
If 2 lines are parallel, they will have equal slopes.
Therefore, the slope of a line parallel to y = 1/4 - 5/4 x will be -5/4
If 2 lines are perpendicular, their slopes are negative reciprocals of each other. So the slope of the perpendicular line = -1 ÷ -5/4 = 4/5
Answer:
x-intercept(s): (-2, 0), (6, 0)
y-intercept(s): (0, -6)
Step-by-step explanation:
An x-intercept represents the point(s) at which the parabola intersects the x axis. A parabola can have 0, 1, or 2 x-intercepts.
A y-intercept represents the point at which the parabola intersects the y axis. A parabola always has exactly 1 y-intercept.

Answer: hot dog = $1.75
<u>Step-by-step explanation:</u>
Let h represent hot dogs and c represent bags of chips.
Customer 1: 4h + 2c = 9.00 → 3(4h + 2c = 9.00) → 12h + 6c = 27.00
Customer 2: 5h + 3c = 11.75 → -2(5h + 3c = 11.75) → <u>-10h - 6c </u>= <u>-23.50</u>
2h = 3.50
<u> ÷2 </u> <u> ÷2 </u>
h = 1.75
2y + 2(y-2) = 5y - 3(y-10)
2y + 2y - 4 = 5y -3y +30
4y - 4 = 2y + 30
4y - 2y = 30 + 4
2y = 34
y = 34/2
y = 17
Answer:
The dashed hypotenuse measures: 3,205.13 ft.
Step-by-step explanation:
. B (Plane is here)
. .
. .
A . . . . . . . C
BC = 500 ft
Angle (Ф) between AB and AC = 9 degrees
So,
Sin(Ф) = BC/AB
Since we need to know how much hypotenuse AB measures, Let's isolate it from the equation:
AB = BC / Sin (Ф)
AB = 500 ft. / Sin (9)
AB = 500 ft./ 0.156
AB = 3,205.13 ft.
