at what ordered pair do the lines x=-2 and y=5 intersect?

Answer:

Zuri: -10x + 125, Cara: 10x+125, Julio: 125x + 10

Step-by-step explanation:

Zuri starts with 125 dollars, and spending 10 dollars per month, means a subtraction of $10 per month.  So, after x months, the subtraction = -10x = -10 + -10 + ... + -10, x times.  Thus, f(x) = 125 + (- 10x) = 125 - 10x = -10x + 125.

Cara starts with 125 coins, and collecting 10 coins per year, means an addition of 10 coins per year.  So, after x years, the addition = 10x = 10 + 10 + ... + 10, x times.  Thus, f(x) = 125 + 10x = 10x + 125.

Julio starts with $10, and earning $125 per week, means an addition of $125 per week.  So, after x weeks, the addition = 125x = 125 + 125 + ... + 125, x times.  Thus, f(x) = 10 + 125x  = 125x + 10.

Answer:

  3 hours

Step-by-step explanation:

After 1 hour, the planes are separated by a distance of 180 +330 = 510 miles. At that rate, the time it takes for them to be 1530 miles apart is ...

  time = distance/speed

  time = (1530 mi)/(510 mi/h) = 3 h

After 3 hours, the planes will be 1530 miles apart.

Answer:

380

144

147

345

114

368

296

174

62

Answer:

30 x 6 = 180

95 x 4 = 380

48 x 3 = 114

21 x 7  = 147

69 x 5 = 345

38 x 3 = 114

46 x 8 = 368

74 x 4 = 296

29 x 6 = 174

31 x  2 = 62

25 guests is 2.5 times more than 10

Multiply each order by 2.5

Chicken = 16 x 2.5 = 40

Lasagna = 7 x 2.5 = 17.5 , round to 18

Deli meat = 1.8 x 2.5 = 4.5, round to 5

Sliced cheese = 15 x 2.5 = 37.5, round to 38

Buns = 1 x 2.5 = 2.5, round to 3

Potato salad = 2 x 2.5 = 5

Answer:

what's the math question?

Step-by-step explanation:

Step 1: Take the first digit of the dividend. ...

Step 2: Then divide it by the divisor and write the answer on top as the quotient.

Step 3: Subtract the result from the digit and write the difference below.

Step 4: Bring down the next number (if present).

Step 5: Repeat the same process.

Answer:

The identity is: cos(x+y)cos(x-y) = cos^2(x) - sin^2(y).  Answer to part (b) is 1/4

Step-by-step explanation:

cos(x+y) = cos(x) cos(y) - sin(x)sin(y)

cos(x-y) = cos(x)cos(y) + sin(x)sin(y)

For convenience, let A = cos(x) cos(y), and B = sin(x) sin(y).

Thus,

cos(x+y) = A - B

cos(x-y) = A + B, and

cos(x+y) cos(x-y) = (A-B)(A+B) = A^2 - B^2 = cos^2(x) cos^2(y) - sin^2(x)sin^2(y) = (1 - sin^2(x))(1 - sin^2(y)) - sin^2(x) sin^2(y) =

1 - sin^2(x) - sin^2(y) + sin^2(x) sin^2(y) - sin^2(x) sin^2(y) =

1 - sin^2(x) - sin^2(y) =

cos^2(x) - sin^2(y)

(b) Let x=45, and y=30, so we have that

cos(75)cos(15) = cos(45+30) cos(45-30) =

cos^2(45) - sin^2(30) =

(sqrt(2)/2)^2 - (1/2)^2 =

2/4 - 1/4 =

1/4

Step-by-step explanation:

oh i hope im right im sorry if wrong

ii. Now consider the second number 8888

Here the last digit of 8888 is 8.

The cube of 8 is 512.

⇒83=512

Here the last digit of 83 is 2.

Hence the one’s digit of the cube of 8888 is 2.

Answer:

B) Domain: All real numbers; Range: y > 3

Step-by-step explanation:

I. x can be any value in real number

but if you look at the graph, the y is near 3 but not 3

So y is more than 3 and x is all real number

When x is domain and y is renge.

That makes domain is real number and renge is more than 3.

If the gray suitcase weighs 11 lb more than the pink suitcase, the pink suitcase weighs 5 lb than the blue suitcase, and the total of 3 suitcases is 127 lb, then the blue suitcase weighs 35.3 lb

Let the gray suitcase be represented by g

Let the pink suitcase be represented by p

Let the blue suitcase be represented by b

The gray suitcase weighs 11 lb more than the pink suitcase

g    =   p   +   11........(1)

The pink suitcase weighs 5 lb than the blue suitcase.

p   =  b  +  5

b  =  p  -  5...........(2)

Total of 3 suitcases = 127 lb

p  +  b  +  g    =  127............(3)

Substitute equations (1) and (2) into equation (3)

p  +  p  - 5 + p  +  11   =  127

3p  +  6   =  127

3p   =  127  -  6

3p   =  121

p  =  121/3

p  = 40.3 lb

Substitute p = 40.3 into equation (2)

b = p - 5

b  = 40.3  - 5

b  =  35.3

The blue suitcase weigh 35.3 lb
