Answer:

x = - 16

Step-by-step explanation:

Value of RHS is not given. If it's 0, then,

x + 4² = 0

x = 0 - 4²

x = 0 - 16

x = - 16

_______

Hope it helps ⚜

Answer:

x = -16

Step-by-step explanation:

=> x = ?

=> x + 4² = ?

=> x + 16 = ?

=> x = -16

Answer:

B

Step-by-step explanation:

3x + 7y = - 49 → (1)

10x - 7y = - 42 → (2)

adding (1) and (2) term by term will eliminate y

13x + 0 = - 91

13x = - 91 ( divide both sides by 13 )

x = - 7

substitute x = - 7 into either of the 2 equations and solve for y

substituting into (1)

3(- 7) + 7y = - 49

- 21 + 7y = - 49 ( add 21 to both sides )

7y = - 28 ( divide both sides by 7 )

y = - 4

solution is (- 7, - 4 ) → B

Answer:

25/144

Step-by-step explanation:

The probability of it occurring once is 5/12, which means that the probability of it occurring twice is (5/12 x 5/12) = 25/144.

Answer:

Determine the type of elasticity of demand

Answer:

60 x 34 = 2040 mins

Step-by-step explanation:

1hr = 60 min

34 hr = 60 x 34 = 2040 mins

Because one hour is equal to sixty minutes, in order to change the units you have to multiply the number of hours, 34, by 60.

Thus, 34 hours in minutes = 2,040 min.

The first step we take is to find the area of the square since the area of the square is equal to the area of the rectangle

       [tex]area-of-rectangle = area- of-square\\area-of-rectangle = 8*8 = 64in^2[/tex]

Another fact we know is that the length of the rectangle is four times the width.

      L = 4W

Now let's put the variables, found above, into the format to find the area of the rectangle

  [tex]area-of-rectangle = L * W, (L = 4W)\\area-of-rectangle = 4W * W\\\\64 = 4W^2\\16 = W^2\\\\W^2 = 16\\\\W = 4[/tex]

Since the Width is 4, L = 4 * W = 4 * 4 = 16 in.

So the length is 16 inches

Answer:  Series diverges to infinity

========================================================

Explanation:

The leading terms of the numerator and denominator are 5n^5 and 4n^5 respectively. They divide to 5/4. The n^5 portions cancel.

As n approaches infinity, the nth term of the sequence is going to approach 5/4 = 1.25 which is larger than 1.

Adding stuff to a series that's larger than 1, and doing so infinitely many times, means that the partial sums explode to infinity. The partial sums do not approach a finite value. Therefore, this series diverges to infinity.

Answer:

39°

Step-by-step explanation:

Angles that are complement to one another add up to 90 degrees.

Now, to find the measure of Angle 4, we subtract 51 from 90.

Therefore, the answer is 39°.

Answer:

Step-by-step explanation:

which is likely to have a mass close to 3 kilograms?

a. a 5- year old child

b. a bowling ball

c. a lemon

d. an adult lion

A kilogram weighs just over 2 pounds. It weighs 2.2 pounds. That's 2 point 2 pounds.

Multiply 3 times 2 point 2.

bowling ball is right. Some weigh 6 or 7 pounds.

So, we must find the sum of this arithmetic sequence -1,2,5,8,11,14,17

using the arithmetic sequence formula and Sum of an Arithmetic Sequence formula such that an =

a1 + d(n-1)...........where a1 = -1 and a2 = 2.

We can use this information to find the common sum ratio 'd' such that,a2 = a1 + d(2-1)2 = -1 + d(1)...........Then add 1 to both sides to get 3

= We do not need d to find the sum but i decided to show you how to find 'd' in case you needed to find the nth term.

The Sum Formula yields,Sn = n(a1 + a7) / 2,

where n is the number if terms which is 7 in this case, right ?

Then we plug in the first and seventh terms for a1 and a7 such that=

S(7)=

(7)(-1+17) / 2 = (7)(16/2) = (7)(8) = 56

Answer:

229 is the remainder.

Explanation:

In order to find the remainder, insert the value of x in the equation.

Given equation:

Given x value:

Find remainder:

[tex]\sf p(4) = 4^4 - 27[/tex]

[tex]\sf p(4) = 256 - 27[/tex]

[tex]\sf p(4) = 229[/tex]

Answer:

229

Step-by-step explanation:

Here we are given a polynomial p(x) and we need to find the remainder when it is divided by (x-4) . As we know that if a polynomial, say [tex]g(x)[/tex] is divided by [tex]x-a[/tex] then the remainder is [tex]g(a)[/tex] .

Firstly equate [tex] x -4[/tex] with 0 , we have;

[tex]\longrightarrow x -4=0\\[/tex]

[tex]\longrightarrow x =0+4\\ [/tex]

[tex]\longrightarrow x = 4 [/tex]

Now substitute [tex] x =4[/tex] in [tex]p(x)[/tex] ,

[tex]\longrightarrow p(x)= x^4-27\\[/tex]

[tex]\longrightarrow p(4)= (4)^4-27\\[/tex]

[tex]\longrightarrow p(4) = 256 - 27 \\[/tex]

[tex]\longrightarrow \underline{\underline{\boldsymbol{ p(4) = 229}}}[/tex]

Hence the remainder is 229 .

=[tex]9\sqrt{2}[/tex]

Answer:

8

I really hope this helped! :D

Step-by-step explanation:

X squared is equal to 64.

That also means X is the square root of 64.

8*8=64

8 Is the square root of 64, meaning it's also X.

Remember, when you square a number, you multiply it to itself.

8^2= 8*8

4^2=4*4

2^2= 2*2

So on, so forth.

Answer:

Step-by-step explanation:

The number of minivans is not really important for this question. You need only two numbers

Total vehicles = 545

Convertibles   = 106

Equation

% convertibles = (# convertibles / Total)  * 100%

Solution

% convertibles = (106 / 545) * 100%

% convertibles = 19.44%

Answer: 19  percent are convertibles.

Answer:

19%

Step-by-step explanation:

Number of convertibles = 106.

[tex]Percentage = \dfrac{number \ of \ convertible}{Total cars}*100\\\\[/tex]

                  [tex]= \dfrac{106}{545}*100\\\\\\= 19.44[/tex]

                  = 19%
