Answer:

slope: -5/3
y-intercept: 2
x-intercept: 6/5 = 1.2

Step-by-step explanation:

Finding the slope is perhaps easiest done by solving for y.

5x -6 = -3y . . . . subtract 3

y = -5/3x +2 . . . divide by -3

This is slope-intercept form, so we can see both the slope (the coefficient of x, -5/3) and the y-intercept (the constant, +2).

To find the x-intercept, we set y=0 and solve for x. This might be most easily done using the original equation:

5x -3 = 0 +3 . . . . set y = 0

5x = 6 . . . . . . . . . add 3 to get the x-term by itself

x = 6/5 = 1.2 . . . . divide by the coefficient of x. This is the x-intercept.

Slope = -5/3

y-intercept = 2

x-intercept = 6/5

Answer:

1/2

Step-by-step explanation:

Or, 8(x-3)+7= 2x(4-17)

Or, 8x-24+7=2x(-13)

Or, 8x-17= -26x

Or, 34x=17

x=1/2

The Weight On Earth Compared To Some Rando Planet... pls help

earnstyle [38]

Answer:

if your talking about the earth i dont know because no one have ever compared some random planet and earths weight

Step-by-step explanation:

That’s because the planets weigh different amounts, and therefore the force of gravity is different from planet to planet. For example, if you weigh 100 pounds on Earth, you would weigh only 38 pounds on Mercury. That’s because Mercury weighs less than Earth, and therefore its gravity would pull less on your body.

<h3>Answer: Choice C</h3>

P = 11/40 + 1/4 - 1/20

=========================================================

Explanation:

The formula we use is

P(A or B) = P(A) + P(B) - P(A and B)

In this case,

P(A) = 22/80 = 11/40 = probability of picking someone from consumer education
P(B) = 20/80 = 1/4 = probability of picking someone taking French
P(A and B) = 4/80 = 1/20 = probability of picking someone taking both classes

So,

P(A or B) = P(A) + P(B) - P(A and B)

P(A or B) = 11/40 + 1/4 - 1/20

which is why choice C is the answer

----------------

Note: P(A and B) = 1/20 which is nonzero, so events A and B are not mutually exclusive.
