If x=9 and y=−3, evaluate the following expression:20−5y+2x

Answer:

(3,7)

Step-by-step explanation:

Answer:

m∠QRS =(10x−12)∘(10x−12) = (10(4.7) - 12) (10(4.7) - 12) = (35) (35) = 1225

Step-by-step explanation:

Answer: Domain = {-4, -1, 0, 2, 7, 8, 13}

The domain is the set of allowed x inputs. So all we do is list the set of x values in the top row of the table.

In contrast, the range is the set of possible y outputs. So the range would be {5,2,-3,7,4,9}. Any duplicate items in the range are tossed out. Optionally you can order the set from smallest to largest, but that's not required. This is because order in a set doesn't matter.

Answer:

111

Step-by-step explanation:

Answer:

X=14 , 5 , 2.5 , 9 , 5 , 15 , -2 ,-2 ,-10 , 13 ,- 3 , -11 , 0 , 0.5833..., -1.666....

Add 37 to both sides

Step-by-step explanation:

Answer:

The first step is to add 37 to both sides of the equation. i.e. grouping like terms.

12x - 37 = 23

12x - 37 + 37 = 23 + 37

12x  - 0 = 60

12x = 60

To go on from there, you divide both sides by 12, i.e. removing common factors:

12x = 60

12x ÷ 12 = 60 ÷ 12

x = 5

Answer:

1.05

Step-by-step explanation:

The rate of change of the cost, in dollars, with respect to the number of minutes purchased is 1.05 and this can be determined by differentiating the given function.

Given :

In order to determine the rate of change of the cost, in dollars, with respect to the number of minutes purchased, differentiate the given function with respect to 'x'.

y = 5.45 + 1.05(x + 7)

y = 5.45 + 1.05x + 7.35

y = 12.8 + 1.05x

Now, differentiate the above equation with respect to 'x'.

[tex]\dfrac{dy}{dx} = 0 + 1.05[/tex]

So, the rate of change of the cost, in dollars, with respect to the number of minutes purchased is 1.05.

Answer:

91.66666666666667

Step-by-step explanation:

240,000/100 = 220,000/x

220,000 x 100 = 22,000,000

22,000,000 divided by 240,000 = 91.66666666666667

Answer:

This type of problem requires you to calculate the Percentage decrease

Step-by-step explanation:

Formula: Percentage Decrease=

Starting Value minus Final Value / Starting Value x 100

240,000 - 220,000 = 20,000

so 20,000/240,000 = 0.0833333333

so 0.0833333333 x 100 =8.33333333%

ans.  8.33333333% decrease in the price of the house.

Answer:

2006 years old.

Step-by-step explanation:

If it had 50% of its carbon-14 it would be 5730 years old.

Since it has 65% left it is younger than 5730 years.

So it is (1 - 0.65) * 5730

= 2005.5 years old.

Answer:

Table C

Step-by-step explanation:

Divide each y value by the corresponding x value for all given ordered pairs. All 3 divisions for each table must equal 1.5.

Start with Table A:

A:

7.5/5 = 1.5    Yes

19.5/ 13 = 1.5     Yes

33/23 = 1.4347...    No

Move on to Table B:

B:

9.5/8 = 1.1875   No

Move on to Table C:

C:

12/8 = 1.5   Yes

19.5/13 = 1.5   Yes

27/18 = 1.5   Yes

Answer: Table C

Answer:

  x ≥[tex]\frac{-5}{2}[/tex]

Step-by-step explanation:

step(i):-

Given inequality

               3x + 7 ≥ x +2

subtracting '2' on both sides, we get

          ⇒ 3x + 7 -2 ≥ x+2-2

         ⇒  3 x + 5 ≥ x

    subtracting 'x' on both sides, we get

           3x +5 -x≥ x-x

       ⇒ 3x +5 -x ≥ 0

      ⇒ 2 x + 5≥ 0

Step(ii):-

subtracting '5' on both sides ,we get

         2 x + 5 -5 ≥ 0-5

   ⇒  2 x ≥ -5

  ⇒  [tex]\frac{2}{2} x\geq \frac{-5}{2}[/tex]

Final answer:-

 ⇒    x ≥[tex]\frac{-5}{2}[/tex]
