50 years ... 2.5 degrees
1 year ... x degrees = ?

If you would like to know what is the rate of change in worldwide temperatures per year, you can calculate this using the following steps:

50 * x = 2.5 * 1
50 * x = 2.5      /50
x = 2.5 / 50
x = 0.05 degrees per year

Result: The rate of change is 0.05 degrees per year.

The function y = square root sign x is translated using the rule (x, y) → (x – 7, y + 2)to create f(x). What is the domain of f(
Mama L [17]

Answer:

Second option {x | x > 7}

Step-by-step explanation:

We have the function

y = \sqrt{x}

We know that the square root of a negative number has no solution in the real ones. Therefore the domain of this function is x > 0

When applying the transformation:

(x, y) \to (x - 7, y + 2) we have a translation of the original function in 7 units to the right and 2 units to the top:

f(x) = \sqrt{x-7} + 2

In the same way we must guarantee that (x-7)> 0

Then x > 7.

Therefore the domain of f(x) is {x | x > 7}

Which shows the factored form of x2 – 12x – 45?
Oxana [17]
Hi!

(x+a)·(x+b) = x²+xa+xb+ab = x²-12x-45

x² = x²
xa+xb = (a+b)x = -12x ⇒ (a+b) = -12
ab = -45

When (a+b) = -12 and ab = -45?

+3-15 = -12 and (+3)(-15) = -45 
-3-15 = -18 and (-3)(-15) = +45
+3+15 = +18 and (+3)(+15) = +45
-3+15 = +12 and (-3+15) = -45

Answer:

(x+3)(x-15)

A theater group made appearances in two cities. The hotel charge before tax in the second city was $1000 lower than in the first
Bess [88]

Answer:

  • $5000 in the first city
  • $4000 in the second city

Step-by-step explanation:

Let x represent the pre-tax hotel charge in the first city in dollars. Then the hotel charge in the second city is x-1000 dollars, and the total tax is ...

... 7.5%·x +5%·(x -1000) = 575

... 12.5%·x = 625 . . . . simplify, add 50

... x = 5000 . . . . . . . . divide by 12.5% (=0.125)

The first-city charge was $5000; the second-city charge was $4000.

Team A faces loses of 5,876 points in Round 1 . How much is the loss of points for each of the 26 players of Team A if the loss
Svetllana [295]

Answer:

226 points were lost per player

Step-by-step explanation:

Since we are evenly spreading the points between all 26 players, we need to solve using division.

Basically, we are dividing the 5876 points among the 26 players.

5876/26 = 226

Therefore, if the points were spread evenly among all 26 players, each player would lose 226 points.
