Evaluate the function when x = -2


Someone please help I don’t understand

Answer:(0,4)

Step-by-step explanation:

4x+5y=20

4(0)+5y=20

5y=20

5x/5=20/5

y=4

4x+5(4)=20

4x+20=20

   -20   -20

4x=0

4x/4=0/4

x=0

4x+5y=20

4(0)+5(4)=20

0+20=20

20=20

Answer:

x= 7

x=6

Step-by-step explanation:

5+2x=19

Subtract 5 from both sides

so...

2x=14

then divide by two to isolate the x

so..

x=7

4x+3=27

Subtract 3 from both sides

so...

4x=24

then divide by 4 to isolate the x

so....

x=6

Answer:  x = 7

       5 + 2x = 19

-5           2x = 14      -5

/2              x = 7       /2

Answer:  x = 6

       4x + 3 = 27

-3           4x = 24       -3

/4             x = 6         /4

Step-by-step explanation:

The magnitude and direction angle of 2(u + v) – 3w is 6.4 and 38.7°

A vector is a quantity or phenomenon that has two independent properties: magnitude and direction. The term also denotes the mathematical or geometrical representation of such a quantity.

Examples of vectors in nature are velocity, momentum, force, electromagnetic fields, and weight.

u = ⟨-2, 6⟩

v = ⟨3, 2⟩

w = ⟨-1, 4⟩

u + v = ⟨-2, 6⟩ + ⟨3, 2⟩

u + v = ⟨-2 + 3, 6 + 2⟩

u + v = ⟨1, 8⟩

2 (u + v) = 2 ⟨-1, 8⟩

2 (u + v) = ⟨2 • 1, 2 • 8⟩

2 (u + v) = ⟨2, 16⟩

-3 w = -3 ⟨-1, 4⟩

-3 w = ⟨-3 • (-1), -3 • 4⟩

-3 w = ⟨3, -12⟩

2 (u + v) - 3 w = 2 (u + v) + (-3 w)

2 (u + v) - 3 w = ⟨2, 16⟩ + ⟨3, -12⟩

2 (u + v) - 3 w = ⟨2 + 3, 16 + (-12)⟩

2 (u + v) - 3 w = ⟨5, 4⟩

Then the magnitude of this vector is

||2 (u + v) - 3 w|| = √(5² + 4²) = √41 ≈ 6.403

Hence, the magnitude and direction angle of 2(u + v) – 3w is 6.4 and 38.7°

Answer:

b

Step-by-step explanation:

The sin trigonometric ratio for angle θ is given by 5/13.

A triangle is a polygon with three edges and three vertices. A triangle with one of the angle as 90 degrees is called right angled triangle. We can use Pythagoras theorem in right angled triangle as -

h² = b² + p²

There are also other different types of triangles such as -

equilateral triangle , scalene triangle , isosceles triangle etc.

Given is a right angled triangle as shown in the image attached.

The sin trigonometric ratio is given by

sin (θ) = 5/13

Therefore, the sin trigonometric ratio for angle θ is given by 5/13.

36.864

Step-by-step explanation:

Answer:

David gets £24, Stephen gets £36, and June gets £36.

Step-by-step explanation:

Firstly, add the ratio values together.

2:3:3  ⇒  2 + 3 + 3 = 8

Next, divide £96 (your total) by 8.

£96 ÷ 8 = £12

Now, we have the number of pounds for 1 value.

Multiply 12 by each ratio value.

12 × 2 : 12 × 3 : 12 × 3

= 24:36:36

Therefore, David gets £24, Stephen gets £36, and June gets £36.

I hope this helped! I would really appreciate it if you would please mark me brainliest! Have a blessed day!

Answer:

David = £24

Stephen = £36

June = £36

Step-by-step explanation:

Total amount of money = £96

Ratio = 2:3:3

Total ratio = 2+3+3 = 8

David's share = 2÷8×96 = £24

Stephen's share = 3÷8×96 = £36

June's share = 3÷8×96 = £36

Answer:

b≤−6

here u go

Answer:

Step-by-step explanation:

To solve an inequality, we will solve just like a normal equation. The goal is to isolate b, so we can determine the set of values it can take on.

We need to reverse the operation - 5.3, so we add 5.3.

-1.2b - 5.3 + 5.3 ≥ 1.9 + 5.3

-1.2b ≥ 7.2

We need to reverse the multiplication that is multiplying b by -1.2, so we will divide. However, we must remember an important rule first.

Important: When we divide by a negative number in an inequality, we must reverse the inequality sign, so ≥ becomes ≤.

-1.2b / -1.2 ≥ 7.2 / -1.2

b ≤ -6 (remember to reverse the sign!)

We now substitute our answer in and see if it is correct. We will use a number that is smaller than -6, for example, -8.

-1.2(-8) - 5.3 ≥ 1.9

9.6 - 5.3 ≥ 1.9

4.3 ≥ 1.9 ✅

We can check again with -6, since this and all numbers smaller than it should be a solution set.

-1.2(-6) - 5.3 ≥ 1.9

7.2 - 5.3 ≥ 1.9

1.9 ≥ 1.9 ✅

Answer:

1) The initial down payment is $1,340

2) The total monthly payment is $7,200

3) The total cost of the jet ski on the installment plan is $8,540

4) The finance charge is $1,840

Step-by-step explanation:

The financing model of Sum-R-Fun for a jet ski are as follows;

Sum-R-Fun selling price of a jet ski = $6,700

The initial down payment = 20% of the selling price of the jet ski

The amount the customer pays per month = $200

The duration or the period of the monthly payment = 3 years

1) The initial down payment = 20/100 × $6,700 = $1,340

2) The total monthly payment = Number of months per year × Number of years × The monthly (installment) payment  

∴ The total monthly payment = 12 × 3 × $200 = $7,200

3) The total cost of the jet ski on the installment plan = The initial down payment + The total monthly payment

∴ The total cost of the jet ski on the installment plan = $1,340 + $7,200 = $8,540

4) The finance charge is the cost of the credit given as follows;

The finance charge = The total cost of the jet ski on the installment plan - Sum-R-Fun selling price of a jet ski

∴ The finance charge = $8,540 - $6,700 = $1,840
