Answer:7 + (-5)= 2

Step-by-step explanation:

7 + (-5)= 2 i hope its right'

Given that

(2a+b,11) and (1,a-3b) are equal ordered pair

⇛(2a+b,11) = (1,a-3b)

On comparing both sides then

2a+b = 1 ----------Eqn(1)

11 = a-3b

⇛ a-3b = 11 ------Eqn(2)

⇛ a = 11+3b-------Eqn(3)

On substituting the value of a in Eqn(1) then

⇛ 2(11+3b) + b = 1

⇛(2×11)+(2×3b) + b = 1

⇛ 22 +6b+b = 1

⇛ 22+7b = 1

⇛ 7b = 1-22

⇛ 7b = -21

⇛ b = -21/7

⇛ b = -3

On substituting the value of b in Eqn(3) then

⇛ a = 11+3(-3)

⇛ a = 11-9

a = 2

Therefore, a = -3 and b = 2

Answer:-The value of (a,b) for the given problem is (-3,2).

Answer:

Only option A is correct

Answer:

  b. 0.850887688656

Step-by-step explanation:

Unless the argument of the sine function is specified in degrees or some other angle unit (revolutions, grads, minutes, seconds), it must be assumed to be radians. Here, the argument 310 is not shown as 310°, so we must assume it is 310 radians.

  sin(310) ≈ 0.850887688656

__

Additional comment

  sin(310°) ≈ –0.766044443119

A radian is dimensionless, indistinguishable from a pure number.

Answer:

  linear

Step-by-step explanation:

The function is linear if the ratio of changes in y to changes in x is the same for any set of (x, y) pairs.

  first two pairs: (y2 -y1)/(x2 -x1) = (7 -4)/(2 -1) = 3/1 = 3

  second two pairs: (y3 -y2)/(x3 -x2) = (16 -7)/(5 -2) = 9/3 = 3

The slopes between points are the same for any pair of points, so they all lie on the same line. The function is linear.

Proportional and linear functions are very similar. The only difference is the addition of the “​b​” constant to the linear function. A proportional relationship is just a linear relationship where ​B​ = 0, or where the line passes through the origin (0, 0).

Answer:

x = 10.

Step-by-step explanation:

(5x-1) + (8x+5) + (4x+6) = 180   (the 3 angles in a triangle sum to 180 degrees).

5x + 8x+ 4x - 1 + 5 +6  = 180

17x + 10 = 180

17x = 170

x = 10.

the formula for area of a triangle is 1/2 times the base (4 cm) times the height (5 cm) so the area of the triangle would be 10 cm. to find the area of the rectangle you would divide 10 by 4, which means that w=2.5 cm

Answer:6

Answer:

No

Step-by-step explanation:

Because 10 - 6.79 = 3.21

Rachel will not have enough money left over to buy a pen for cost $3.50.

Subtraction can be done for any numbers or algebraic expressions. It is the process of taking out certain value from a given amount of number.

The process of subtraction can also be termed as finding difference. It is one of the basic operation in mathematics.

A number 'b' subtracted from 'a' is denoted as a - b, read as a minus b.

Total money Rachel has = $10.00

Cost of book = $6.79

If she buy the book,

Remaining money = $10.00 - $6.79

                              = $3.21

Cost of pen = $3.50, which is greater than the remaining money. So Rachel can't buy the pen.

Hence Rachel will not have enough money to buy a pen for $3.50 because she only has a balance of $3.21.

Step-by-step explanation:

Step-by-step explanation:

Let "c" be the original number of classrooms.

The 1200/c was the original number of students per classroom.

----

Equation:

1200/(c-4) = (1200/c)+10

Multiply thru by c(c-4)

---

1200c = 1200(c-4)+10c(c-4)

---

1200c = 1200c-4800 + 10c^2-40c

----

10c^2-40c-4800 = 0

c^2-4c-480 = 0

Factor:

(c-24)(c+20) = 0

Positive solution:

Answer:

The 10th term

Step-by-step explanation:

As we see these are all incrementing by 21 (and divisible by 21), we can divide all the terms by 21 and get 1, 2, 3, ...., 10

Therefore 210 is the 10th term.

Answer:

The 10th term is 210

Step-by-step explanation:

Let's revise our tables of 21.

Therefore, the 10th term will give 210.

Answer:

there is many ways but he could put them side to side or top and bottom

Step-by-step explanation:

Answer:

Stare at it long enough. You will notice that with each step you double the value, and change sign. It makes it a geometric sequence of ratio -2. At this point you have two ways of writing down:

Option 1: Ricorsively, the first term is -5, then the next term is -2 times the previous one:

[tex]\left \{ {{a_0=-5} \atop {a_{n+1}=-2a_n}} \right.[/tex]

Option 2: In closed form, remembering that the n-th term in a geometric sequence is the starting term times the n-th power of the ratio:

[tex]a_n=-5 (-2)^n[/tex]

Either work, depending on what you need to use it for.

[tex]r = \sqrt{\dfrac{3V}{\pi h}}[/tex]

Step-by-step explanation:

Multiply both sides by 3 to get

[tex]\pi r^2h = 3V[/tex]

Then divide both sides by [tex]\pi h[/tex] and you'll get

[tex]r^2 = \dfrac{3V}{\pi h}[/tex]

To solve for r , you need to take the square root of both sides to get

[tex]\sqrt{r^2} = r = \sqrt{\dfrac{3V}{\pi h}}[/tex]
