Answer: x= −16
Step-by-step explanation:
Answer:
4x + y = 10
Step-by-step explanation:
The point-slope form of the equation of a straight line is y - k = m(x - h).
Letting m = -4, 1 = h and 6 = k, we get y - 6 = -4(x - 1).
Now we must rewrite this in standard form. Do this: Carry out the multiplication. We get y - 6 = -4x + 4.
Now add 6 to both sides, obtaining
y = -4x +10
Finally, add 4x to both sides, obtaining:
4x + y = 10. This is the desired equation in standard form.

Answer: Choice D) (6u, -3u)</h3>
===================================
Explanation:
The letter u represents the scale factor. It is some unknown number.
To form the dilation, we multiply this number u by each coordinate of point P (6, -3)
The x coordinate of P is x = 6. It turns into x*u = 6*u which is the x coordinate of P '
Similarly, y = -3 for point P so y*u = -3*u is the y coordinate of point P '
Therefore, we go from P(6, -3) to P ' (6u, -3u)
Answer:
The probability is 63/1000 or 0.063
Step-by-step explanation:
Here, given that she takes 3 coins , we want to calculate the probability that the sum is £2.50
What we simply have to do here is to get the different ways to arrange £2.50 within 3 selections ONLY
we can only have this as;
taking 2 £1 coins and 1 50 pence coins
The probability of taking a £1 coin is 3/10
The probability of taking a 50 pence coin is 7/10
So the probability of 2 £1 coins and 1 50 pence coins will be;
3/10 * 3/10 * 7/10 = 63/1000
