1/12 because if the coin lands on heads there are 6 other numbers it could land on. if the coin lands on tails there are another 6 numbers. so the probability of it landing on heads and rolling a 2 would be 1 out of 12.

Write an equation of the line that passes through (4,−1) and is parallel to the line y=3x+7. (hint: NOT y=3x-13)
CaHeK987 [17]

To find the equation of the line, we are going to use the point-slope form, which is listed below:

(y - y_1) = m(x - x_1)

  • (x_1, y_1) is a point on the line
  • m is the slope of the line

You may notice that we have a point, but no slope is given to us. However, the problem states that the line is parallel to the equation y = 3x + 7, which means that it has the same slope as this line, which is 3. (Remember that this line is set up in y = mx + b form, where m is the slope)


Thus, we can now insert our values into the point-slope formula to find the equation of our line.

(y + 1) = 3(x - 4)

(y + 1) = 3x - 12

y = 3x - 13


The problem made it clear that it didn't want the form y = 3x - 13, so let's put it in standard form:

y = 3x - 13

3x - y = 13


The equation of our line is \boxed{3x - y = 13}.

Two numbers are in the ratio 7:5 and their difference is 22.Find the numbers​
omeli [17]

Answer:

Let x and y be the two numbers. Then

yx=57  and x−y=20

Cross multiplying the proportion

5x=7y  or y=75x

So, x−y=20

x−75x=20⇒77x−5x=72x=20

⇒x=2140=70

y=75x=75×70=50

So smaller number is 50.

Check :yx=5070=57 and 70−50=20
