For this translation, you need to replace every occurrence of "x" with "x-3", and every occurrence of "y" with "y+5".

Answer:

(x,y)\rightarrow (x+3,y-5)

Step-by-step explanation:

In translation by a unit left,

The rule is,

(x,y)\rightarrow (x-a,y)

By a unit Right, rule is,

(x,y)\rightarrow (x+a,y)

By a unit up rule is,

(x,y)\rightarrow (x,y+a)

By a unit down, rule is,

(x,y)\rightarrow (x,y-a)

Hence, the rule describes a translation that is 3 units to the right and 5 units down is,

(x,y)\rightarrow (x+3,y-5)

Help me please I’m begging you:(
alex41 [277]

Answer:

Chips = 14

Pretzel = 14

Cookie = 8

Popcorn = 13

Question Mark = 222

Step-by-step explanation:

First Equation:

Chips + Pretzel + Chips = 42

Third Equation: Chips = Pretzel.

This means that

Pretzel + Pretzel + Pretzel = 42

Pretzel = \frac{42}{3} =14

Chips = Pretzel

Chips = 14

Second Equation:

Cookie + Chips + Cookie = 30

We know that Chips = 14.

Cookie + 14 + Cookie = 30

Subtract 14 on both sides:

Cookie + Cookie = 16

Cookie = 16\div 2 =8.

Fourth Equation:

Cookie + Cookie + Popcorn = 29

We know that Cookie = 8.

8 + 8 + Popcorn = 29

16 + Popcorn = 29

Subtract 16 on both sides:

Popcorn = 13.

Question Mark:

(Popcorn + Popcorn) \times Cookie + Chips = (13 + 13) \times 8 + 14 = 26 \times 8 + 14 = 208+14=222

What is the exact distance from (−4, −2) to (4, 6)?
Gekata [30.6K]
The distance between any two points is:

d^2=(x2-x1)^2+(y2-y1)^2

d^2=(6--2)^2+(4--4)^2

d^2=8^2+8^2

d^2=64+64

d^2=128

d=√128 units
