Y is directly proportional to x when y=30, x=6

Mathematics
1 answer:
lbvjy [14]3 years ago
3 0

Answer:

see explanation

Step-by-step explanation:

Given that y is directly proportional to x then the equation relating them is

y = kx ← k is the constant of proportionality

To find k use the condition when y = 30, x = 6

k = \frac{y}{x} = \frac{30}{6} = 5

y = 5x ← equation of proportionality

When x = 12, then

y = 5 × 12 = 60

write an equation of a line perpendicular to the givin equation using the given point givne (8,2); x = -4
MakcuM [25]

y=-x+10 is the equation of a line perpendicular to the givin equation using the given point given (8,2) and x = -4

<h3>What is Slope of Line?</h3>

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

In the perpendicular lines the product of slopes will be -1

m1m2=-1

y=x+4 is the given line, it has slope of 1, so the perpendicular line will have slope -1.

The line is passing through (8,2)

2=-1(8)+b

2=-8+b

2+8=b

10=b

Hence, y=-x+10 is the equation of a line perpendicular to the givin equation using the given point given (8,2) and x = -4

Minchanka [31]
To evaluate, calculate the total time it took Kahlil to read emails on Tuesday. yy (minutes) = (35 mails x .625) - 2.7 =  19.175 minutes. So comparing the total time it took Kahlil to read his email on Monday (25 minutes) and Tuesday (19.175 minutes), h<span>e spent 6 minutes more checking emails on Monday.</span>
