Answer:

  -222

Step-by-step explanation:

The new value of x is 74/84 of the old value, so the new value of y will also be 74/84 of the old value:

  (74/84)·(-252) = -222

_____

If you like, you can solve for the constant of proportionality (k) in the equation ...

  y = kx

  -252 = k(84)

  -252/84 = k = -3

Then you can use this equation to find the new value of y.

  y = -3·74 = -222

__

As we have seen above, there is no need to discover the value of k if there is only one new x-value to be concerned with. If you have to find y for a number of new x-values, then it can be useful to know what k is.

Answer:

1) √10 units

A=(-1, 0) let us assume (x1, y1)

B=(2, 1) let us assume (x2,y2)

distance= √(x2-x1)^2 + (y2-y1)^2

=√(2+1)^2 + ( 1-0)^2

=√3^2 + 1^2

= √10 units

Combine the like terms:
Anuta_ua [19.1K]

Answer:

1 apple, 10 fingers, 6 flowers

Step-by-step explanation:

Apples are like terms, so 2-1=1 apple.

Fingers are like terms, so 12-2=10 fingers.

Flowers remains unchanged, since no other terms are like terms (have flowers following the number).
