What’s the range of A and B and both

Answer: Yes, we can add them as they are like terms

               The answer we get after adding is 9xy

Step-by-step explanation:

Even though 'xy' and 'yx' seem to be different, we must remember that multiplication is commutative and hence 'xy' and 'yx' are the same

The answer we get after adding is 9xy

Answer:

Yes, and you get 9xy

Step-by-step explanation:

4yx = 4xy

Yes, you can add them.

5xy + 4xy = 9xy

Answer:

Polynomials are expressions with one or more terms with a non-zero coefficient. A polynomial can have more than one term. In the polynomial, each expression in it is called a term.

Solution given:

1:x²-5x+6

let

f(x)=x²-5x+6

It is polynomial in one variable x

According to definition of variable

f(x)=0

substituting value of f(x)

x²-5x+6=0

Doing middle term factorisation

6=3*2*1

remember that in front of constant term is positive sigh

so we need to add factor of 6 to get 5

I.e. 3+2=5

substituting (3+2) in place of 5

x²-(3+2)x+6=0

x²-3x-2x+6=0

taking common from each two term

x(x-3)-2(x-3)=0

again taking common

(x-3)(x-2)=0

either

x-3=0

or

x-2=0

2:

4x³-3x²+2

let

f(x)=4x³-3x²+2

It is polynomial in one variable x.

According to definition of variable

f(x)=0

we cannot solve it by factoring so solving by graph

Graph is in attachment.

The solution is the x-value of the point of intersection.

x≈−0.60700729

Answer:

  B. 73.5 in²

Step-by-step explanation:

The triangle area is half the rectangle area, so the shaded area is also half the rectangle area:

  A = 1/2LW = 1/2(21 in)(7 in) = 73.5 in²

Step-by-step explanation:

I got it correct on founders edtell

the value of Zis 8.

Z =2^3=8

Now we have to,

find the required value of Z.

→ Z = 2^3

→ [Z = 8]

Therefore, value of Z is 8.

Answer:

the addition of "1" to the quantity under the radical sign.

Step-by-step explanation:

Using a regression equation :

The confidence interval is obtained using the relation :

yhat ± t(α/2) * s√(1/n + (Xp - xbar)²/SSx)

yhat = Predicted value

s = estimated standard deviation of yhat

x = Xp

The prediction interval is obtained using the relation :

yhat ± t(α/2) * s√(1 + 1/n + (Xp - xbar)²/SSx)

Hence, from the formula stated abibeb, we can see that, the only difference is the 1 added to the prediction interval formula.

Answer: [tex]17.5t[/tex]

Step-by-step explanation:

Given

Speed of boat A is [tex]v_a=9\ mi/hr[/tex]

Speed of boat B is [tex]v_b=15\ mi/hr[/tex]

Both are moving perpendicular to each other

Distance traveled by Boat A [tex]x_a=9t[/tex]

Distance traveled by Boat B [tex]x_b=15t[/tex]

Distance between them is given by Pythagoras theorem

[tex]\Rightarrow d^2=(x_a)^2+(x_b)^2\\\\\Rightarrow d^2=(9t)^2+(15t)^2\\\\\Rightarrow d=\sqrt{(9t)^2+(15t)^2}\\\\\Rightarrow d=\sqrt{81t^2+225t^2}\\\\\Rightarrow d=\sqrt{306t^2}\\\\\Rightarrow d=17.49t\approx 17.5t\ \text{miles}[/tex]

Distance between them is [tex]17.5t[/tex]

Answer:

x⁵/³y

Step-by-step explanation:

x⁵/³y is equivalent to ³✓x⁵y.

Answer:

y = 5x + 23

Step-by-step explanation:

y2 - y1 / x2 - x1

8 - (-2) / -3 - (-5)

10 / 2

= 5

y = 5x + b

-2 = 5(-5) + b

-2 = -25 + b

23 = b

Answer:

The polar equation of the curve is:

[tex]r=8c*cos(\theta)[/tex]

Step-by-step explanation:

In polar form x and y could be written as:

[tex]x=rcos(\theta)[/tex]

[tex]y=rsin(\theta)[/tex]

Taking the square of each value we have:

Let's recall that [tex]cos^{2}(\theta)+sin^{2}(\theta)=1[/tex]

[tex]x^{2}+y^{2}=r^{2}(cos^{2}(\theta)+sin^{2}(\theta))[/tex]

[tex]x^{2}+y^{2}=r^{2}[/tex]

Then, the cartesian equation is rewritten as:

[tex]x^{2}+y^{2}=8cx[/tex]

[tex]r^{2}=8c*rcos(\theta)[/tex]

Therefore, the polar equation of the curve is:

[tex]r=8c*cos(\theta)[/tex]

Answer:

$0.85

Step-by-step explanation:

$4.25 divided by 5 pounds equals $0.85 per pound.

Answer:

$0.85

Step-by-step explanation:

Find the unit rate.

4.25/5=x/1

Solve for x. X= 4.25/5=0.85

So 1 lb of tangerines costs $0.85.

Answer:

$1487.50

Step-by-step explanation:

9514 1404 393

Answer:

  $1487.50

Step-by-step explanation:

The amount of interest due is ...

  I = Prt

where P is the loan amount, r is the annual rate, and t is the number of years. Here, t = 6 months = 1/2 year, so the interest due is ...

  I = $1400×0.125×1/2 = $87.50

The total amount due is the sum of the loan amount and the interest:

  due = $1400 +87.50 = $1487.50

The total amount due after 60 months is $1487.50.

Answer:

c= none of the above

Step-by-step explanation:

-3x- 6/10

This has two separate terms, a term with a variable

-3x  and a term with a constant -6/10

A=3/6x1/10  This has only one term

b=- 3/10x-6  This has a different x term -3/10  which is not -3

c= none of the above

Answer:

1320 ways

Step-by-step explanation:

Number of contestants = 12

Positions that are n be awarded = First, Second, Third

Number of contestants who could be first = 12 (all 12 contestants)

Number of contestants who could be second = 11 (all 12 contestants - first)

Number of contestants who could be third = 10 (all 12 contestants - first and second )

The number of ways prices can be given :

(1st * 2nd * 3rd) = 12 * 11 * 10 = 1320 ways

Answer:

The value of x is [tex]\frac{7\sqrt{6}}{2}[/tex]

Solution given:

AB=7

BD=x

<BAC=60°

<DBC=45°

In right angled triangle ABC

Tan 60°=opposite/adjacent

Tan 60°=BC/AB

Substitute value

[tex]\sqrt{3}[/tex]=[tex]\frac{BC}{7}[/tex]

BC=[tex]7\sqrt{3}[/tex]

again

In right angled triangle BCD

Using Cos angle

Cos 45=adjacent/hypotenuse

Cos45°=BD/BC

Substituting value

[tex]\frac{\sqrt{2}}{2}=\frac{x}{7\sqrt{3}}[/tex]

Doing criss cross multiplication

[tex]\frac{\sqrt{2}}{2}*7\sqrt{3}=x[/tex]

x=[tex]\frac{7\sqrt{6}}{2}[/tex]

Answer:

Step-by-step explanation:

The attache graph shows the solution region is bounded by lines through the points (-2, 4), (6, 0), and (3, -6).

The solution (x, y) = (-2, 4) gives the maximum value of z: 16.

The solution (x, y) = (3, -6) gives the minimum value of z: -24.

Answer:

B) 399

Step-by-step explanation:

We want to find the sum of the arithmetic series given that:

[tex]a_1=9, \, d = 3, \text{ and } n = 14[/tex]

In other words, we want to find the sum of the first 14 terms of the series when the first term is 9 and the common difference is 3.

Recall that the sum of an arithmetic series is given by:

[tex]\displaystyle S = \frac{n}{2}\left(a + x_n\right)[/tex]

Where n is the amount of terms, a is the first term, and xₙ is the nth or last term.

We will need to find the last term. We can write a direct formula. The general form of a direct formula is given by:

[tex]x_n=a+d(n-1)[/tex]

Since the initial term is 9 and the common difference is 3:

[tex]x_n=9+3(n-1)[/tex]

Then the 14th or last term is:

[tex]\displaystyle x_{14}=9+3((14)-1)=9+39=48[/tex]

Then the sum of the first 14 terms is:

[tex]\displaystyle \begin{aligned} S_{14} &= \frac{14}{2}\left(9+48\right) \\ \\ &= 7(57) \\ \\ &= 399\end{aligned}[/tex]

Our answer is B.

Answer:

I believe the answer is  d = 32

Step-by-step explanation:

You should isolate the radical, then raise each side of the equation to the power of its index.

9514 1404 393

Answer:

  d = 32

Step-by-step explanation:

Add 4, then square, and solve the resulting linear equation.

  √(7d +1) = 15

  7d +1 = 225 . . . . . . square both sides

  7d = 224 . . . . . . . . subtract 1

  d = 32 . . . . . . . . . . divide by 7
