Triangle PQR has vertices P(–2, 6), Q(–8, 4), and R(1, –2). It is translated according to the rule (x, y) → (x – 2, y – 16).

Amanda [17]

Since you subtract 16 from the y value, P is (-2, 6), and the y value comes second (meaning that it's 6), we get 6-16=-10

mylen [45]

Answer:

${x}^{2} + 9x + 20$

Step-by-step explanation:

1) Use FOIL method: (a + b) (c + d) = ac + ad + bc + bd.

${x}^{2} + 5x + 4x + 20$

2) Collect like terms.

${x}^{2} + (5x + 4x) + 20$

3) Simplify.

${x}^{2} + 9x + 20$

Therefor, the answer is x² + 9x + 20.

You and a friend go to surf taco for lunch. you order 3 soft tacos and 2 burritos and your total bill is 25. Your friend bill is

Salsk061 [2.6K]

Answer:

Step-by-step explanation:

Let the cost of one soft taco = s

Let the cost of one burrito = b

So we have this system

3s + 3b = 11.25

4s + 2b = 10.00 (1)

Divide the first equation through by 3 and we have that

s + b = 3.75 subtract b from both sides

s = 3.75 - b (2)

Sub (2) into (1) and we have

4 (3.75 - b) + 2b = 10.00 simplify

15 - 4b + 2b = 10.00

-2b + 15 =10.00 subtract 15 from both sides

-2b = - 5.00 divide both sides by -2

b = 2.50

And using (2)

s = 3.75 - 2.50 = 1.50

So... a soft taco 1.50 and a burrito is 2.50
