Write an equation which is perpendicular to the line of y= -5/2x+2​

Mathematics
1 answer:
S_A_V [24]3 years ago
3 0

Answer:

y = 2/5x

Step-by-step explanation:

Perpendicular lines are lines which have negative reciprocal slopes of each other.

The line y = -5/2 x + 2 has slope -5/2. Therefore its perpendicular slope will be 2/5.

The equation can cross anywhere on the y-axis for its y-intercept since no specific point is given. Here I chose (0,0).

y = 2/5x

Answer:

1. 23

2. 8

Step-by-step explanation:

☆Cross multiply.

\frac{2}{10}  =  \frac{4}{a - 3}  \\  \\ 40 = 2(a - 3) \\ 40 = 2a - 6 \\   \frac{ + 6  =  \:  \:  \:  \:  \:  \:  \:  \:  + 6}{ \frac{46}{2} =  \frac{2a}{2}  }  \\  \\ 23 = a

--------

\frac{k}{6}  =  \frac{4}{3}  \\  \\  \frac{24}{ 3}  =  \frac{3k}{3}  \\  \\ 8 = k

Which equation could possibly represent the graphed function?
Veseljchak [2.6K]

Answer:

A

Step-by-step explanation:

You're looking for x-intercepts

From the graph you know that the x-intercepts are as follows:

x = -4, x = -2, x = 4

And this is when y or f(x) = 0

so you can rewrite each x-intercept as an equation

0 = x + 4

0 = x + 2

0 = x - 4

Now you know each of the terms

f(x) = (x-4)(x+2)(x+4)

What is the equation of the line with a y-intercept of −10 and a slope of 3
Anika [276]

Step-by-step explanation:

we have y intercept -10

and slope 3

we know the equation of line in slope -intercept form

y=mx+b

where m is slope and b is y-intercept

so the final equation would be

y=3x-10
