Answer:

5x - 8y = -48

Step-by-step explanation:

Move 5/8x to the y side to get (-5/8)x + y = 6. Multiply both sides by -8 to get 5x - 8y = -48.

[tex]C(x) =20x +500[/tex]

profit

[tex]P(x) =R(x) - C(x)[/tex]

Required

the value of  P(x)

Step two:

substituting we have

[tex]P(x) =35x- (20x+500)\\P(x)=35x-20x-500\\\\P(x)=15x-500[/tex]

Option C is correct

c) 15x-500

Answer:

a= 24b/5c b= 5ac/24 c= 24b/5a

Step-by-step explanation:

Put the problem into a calculator that can solve with variables.

The solution set for the given equation is x=-1 .

Solution set is written as {-1}

for better understanding check the calculation below.

We need to solve the given equation

[tex]\frac{x+3}{x+2} =3+\frac{1}{x}[/tex]

To solve any equation we take LCD.

LCD of the given equation is x(x+2)

Multiply LCD with each term to remove the denominator

[tex]\frac{x+3}{x+2}\cdot x(x+2) =3\cdot x(x+2)+\frac{1}{x}\cdot x(x+2)\\x(x+3)=3x(x+2)+x+2\\x^2+3x=3x^2+6x+x+2\\[/tex]

Subtract x^2 and 3x from both sides of the equation to get 0 on the left side of the equation

[tex]0=3x^2+6x+x+2-x^2-3x\\0=2x^2+4x+2\\[/tex]

Now divide the whole equation by 2 and then we factor it

[tex]0=x^2+2x+1\\0=(x+1)(x+1) \\x+1=0\\x=-1[/tex]

The solution set for the given equation is x=-1

Solution set is written as {-1}

Answer:

x2 • (x2 - 32772)

Step-by-step explanation:

step 1:  ((x4) -  22x2) -  32768x2

step 2: Pull out like factors :

  x4 - 32772x2  =   x2 • (x2 - 32772)

Factoring:  x2 - 32772

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

        A2 - AB + BA - B2 =

        A2 - AB + AB - B2 =

        A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check : 32772 is not a square !!

Ruling : Binomial can not be factored as the difference of two perfect squares.

Answer:

(A) I think

Step-by-step explanation:

We you divide x12 and y18,12=4 y=6. Then you take +1 and change it to -1. It should bring you to answer A.

I hope I'm right and I hope this helps:)!

Answer:

The answer is A:

[tex](x^{4}y^{6} - 1)(x^{8}y^{12} - x^{4}y^{6} + 1)[/tex]

Step-by-step explanation:

To solve this question, first apply the exponent rule to the entire equation:

[tex]x^{12}y^{18} + 1[/tex]

[tex]= (x^{4}y^{6})^{3} + 1^{3}[/tex]

Next, we can apply the Sum of Cubes formula. To refresh your memory, the formula is as thus:

[tex]x^{3} + y^{3} = (x + y)(x^{2} - xy + y^{2})[/tex]

So, let's apply this to the equation above:

[tex](x^{4}y^{6})^{3} + 1^{3}[/tex]

[tex]= (x^{4}y^{6} + 1)((x^{4}y^{6})^{2} - x^{4}y^{6} + 1^{2})[/tex]

[tex]= (x^{4}y^{6} + 1)((x^{4}y^{6})^{2} - x^{4}y^{6} + 1^{2})[/tex]

[tex]= (x^{4}y^{6} - 1)(x^{8}y^{12} - x^{4}y^{6} + 1)[/tex]

Therefore, the answer is A.

Answer:

$1.17

Step-by-step explanation:

$0.26*4.5= $1.17

Answer:

$1.17

Step-by-step explanation:

X will be the answer

0.26*4.5=X

All you have to do is multiply but if that's too hard then just do

.26+.26+.26+.26+.13

Once you are done doing the math then your final equation should be:

0.26*4.5= 1.17

Answer:

[tex]Hypotenuse = 25cm[/tex]

[tex]Opposite = 24cm[/tex]

[tex]Adjacent = 7cm[/tex]

Step-by-step explanation:

Represent:

Given that:

[tex]c = 1 + a[/tex]

[tex]c = 4 + 3b[/tex]

Required

Solve for a, b and c

[tex]c = c[/tex]

So, we have:

[tex]1 + a = 4 + 3b[/tex]

Subtract 1 from both sides

[tex]a = 4 -1 + 3b[/tex]

[tex]a = 3 + 3b[/tex]

Apply Pythagoras Theorem

[tex]c^2 = a^2 + b^2[/tex]

Substitute 3 + 3b for a and 4 + 3b for c

[tex](4 + 3b)^2 = (3 + 3b)^2 + b^2[/tex]

Open brackets

[tex]16 + 12b+12b+9b^2 = 9 + 9b+9b+9b^2 +b^2[/tex]

[tex]16 + 24b+9b^2 = 9 + 18b+10b^2[/tex]

Collect Like Terms

[tex]10b^2 - 9b^2 + 18b - 24b + 9 - 16 = 0[/tex]

[tex]b^2 - 6b -7 = 0[/tex]

Expand

[tex]b^2 +b-7b-7=0[/tex]

Factorize:

[tex]b(b+1)-7(b+1) =0[/tex]

[tex](b-7)(b+1) = 0[/tex]

Split:

[tex]b - 7 = 0\ or\ b+1=0[/tex]

[tex]b = 7\ or\ b=-1[/tex]

But the adjacent of a triangle can't have a negative measurement.

So:

[tex]b = 7[/tex]

Recall that:

[tex]c = 4 + 3b[/tex]

[tex]a = 3 + 3b[/tex]

Substitute 7 for b in the above expressions

[tex]c = 4 + 3 * 7[/tex]

[tex]c = 4 + 21[/tex]

[tex]c = 25[/tex]

[tex]a = 3 + 3 * 7[/tex]

[tex]a = 3 + 21[/tex]

[tex]a = 24[/tex]

Hence, the dimensions of the triangle are:

[tex]Hypotenuse = 25cm[/tex]

[tex]Opposite = 24cm[/tex]

[tex]Adjacent = 7cm[/tex]

Answer: The answer is C, 1/3 cup.

Answer:

We conclude that

Step-by-step explanation:

Given the set

If we closely observe, we can easily identify that set A has 4 elements, which are 2, 3, 5, and 7.

n(A) denotes the number of elements in a set.

Since set A has 4 elements, therefore the value of n(A) = 4

Thus, we conclude that

Presenting a graph with a skewed scale is a data collection error. The correct option is A.

The field data collection error is the study of the erroneous sample or inaccurate data, not the study of missing data. It might be challenging to maintain a high response rate on a large-scale survey.

The answer would be a data collection error. Interpretation doesn’t have an effect on how the graph is originally graphed, and neither does measurement. Sampling could be an answer, however, data collection makes more sense.

Hence, the correct option is A.

Answer:

Yes, they have the same slope

Step-by-step explanation:

Both y=2 and y=-4 have the same slope, a slope of zero, because when they are graphed, both of them form a straight horizontal line. And since they both form a straight horizontal line, they are parallel because they have the same slope.
