Which equations represent the line that is perpendicular to the line 5x - 2y=-6 and passes through the point (5,-4)? check all that apply

The equation of the line would be y = -2/5x - 2

Step-by-step explanation:

In order to find this, we first need to find the slope of the first equation. We can do this by solving for y.

5x - 2y = -6

-2y = -5x - 6

y = 5/2x + 3

Now that we have the slope of 5/2, we know that the perpendicular slope is -2/5. We know this because it is the opposite and reciprocal. Now, we can use this along with a point to solve in point-slope form.

y - y1 = m(x - x1)

y - -4 = -2/5(x - 5)

y + 4 = -2/5x + 2

y = -2/5x - 2

probability for j is 1/4

while

a is 1/6

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
