A: no solution!

first, simplify each side of the equation.

3x + 5 - 10x simplifies to -7x + 5.
8 - 7x - 12 simplifies to -7x - 4.

then, add +7x on both sides of the equation to get the variable alone. if you add 7x to each side, you get left with 0.

so, that leaves 5 = -4 which is not true. so, that means there is no solution.

THESE IS THE COMPLETE QUESTION:

A bucket contains one green block, one red block, and two yellow blocks. You choose one block from the bucket.

A)Find the theoretical probability that you will choose each color.

B)Find the sum of probability in(a)

C)What is the probability that you will not choose a red block?

D)Find the sum of the probabilities of choosing a red block and probability of not choosing a red block

EXPLANATIONS:

Sample of blocks: green,red, yellow, yellow

Total sample =4

Green sample = 1

Red sample 1

Yellow sample = 2

A)To find the theoretical probability that you will choose green.

i) P( choosing a green block)= green sample/Total sample

=1/4

To find the theoretical probability that you will choose red

ii)P(choosing a red block) = Red sample block/Total sample of blocks

= 1/2

To find the theoretical probability that you will choose yellow

iii) P(choosing a yellow block) = 1/4

B)The sum of probability in( a)

=P( choosing a green block) + P( choosing a Red block) +P( choosing a yellow block)

= 1/4 + 1/2 + 1/4

C)P( Not choosing a red block) = 1 - 1/4

= 3/4

D)P(Sum of choosing a red block and not choosing a a red block)

=1/4 + 3/4

= 1

Passing through (2, - 2) and perpendicular to the line whose equation is y= 5x+2

jonny [76]

Step-by-step explanation:

Hey there!!!

Here,

Given, A line passes through point (2,-2) and is perpendicular to the y= 5x+2.

The equation of a straight line passing through point is,

$(y - y1) = m1(x - x1)$

Now, put all values.

$(y + 2) = m1(x - 2)$

It is the 1st equation.

Another equation is;

y = 5x +2........(2nd equation).

Now, Comparing it with y = mx + c, we get;

m2=5

As per the condition of perpendicular lines,

m1×m2= -1

m1 × 5 = -1

Therefore, m2= -1/5.

Keeping the value of m1 in 1st equation.

$(y + 2) = \frac{ - 1}{5} (x - 2)$

Simplify them.

$5(y + 2) = - x + 2$

$5y + 10 = - x + 2$

$x + 5y + 8 = 0$

Therefore the required equation is x+5y+8= 0.

Hope it helps...
