evaluate (-1/3)x2/5x(-9)

Answer:x = 6

Step-by-step explanation:

Answer:

x=6

Step-by-step explanation:

Add  5 to both sides of the equation:

2x -5 = 7

2x -5 +5 =7 +5

Simplify:

2x=12

Divide both sides of the equation by the same term:

2x = 12

2x/2 = 12/2

Simplify again:

x=6

Answer:

x = 6

Step-by-step explanation:

1.875/500

Step-by-step explanation:

line that is perpendicular to the given line :

y = 2/3x + 5

m1 × m2 = -1

m1 = the coefficient of x

m1 = 2/3

remember : m1 × m2 = -1

2/3 x m2 = -1

2m2 ÷ 3 = -1

(let m2 = x)

2x ÷ 3 = -1

(cross multiply)

2x = 3 × -1

2x = -3

(divide both sides by the coefficient of x)

x = -3/2

Remember : m2 =x

m2 = -3/2

The line that passes through the point (4,2) ;

( note : x¹ = 4 , y¹ = 2)

m = (y - y1) ÷ (x - x1 )

-3/2 = (y - 2) ÷ (x - 4)

(cross multiply)

-3(x - 4) = 2 (y - 2)

-3x +12 = 2y - 4

(make y the subject of formula )

-3x + 12+ 4 = 2y

-3x + 16 = 2y

(

(divide through by the coefficient of y)

-3x/ 2 + 16/2 = y

-3/2x + 8 = y

Answer:

889.021796 (or simplifyed, 889.02)

Step-by-step explanation:

1 USD = 1.3021 EU

so what we do here is multiply 1.3021 and 682.76

1.3021 x 682.76 = 889.021796

Answer:

(f - g)(x) = -8x²

(f - g)(2) = -32

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

Step 1: Define

f(x) = -10x² - x

g(x0 = -2x² - x

(f - g)(x) is f(x) - g(x)

(f - g)(2) is f(2) - g(2)

Step 2: Find (f - g)(x)

Step 3: Evaluate

And we have our answers!

Answer:

1 / x^3

I don't know what you mean by trying to get more characters by the way sorry.

Step-by-step explanation:

Exponents rule will change X^-3 / x^0 to x^-3-0

Subtract the exponents to get x^-3

Since exponents cannot be negative, the answer will be changed to a fraction 1/x^3.

Answer:

(2,3 is dilated to 8,12 by a scale factor of 4)

Step-by-step explanation:

multiply 2,3 by numbers until it gets to 8,12, once you multiply by 4 you get 8,12 which means the answer is a scale factor of 4

Answer:

  x = 7

Step-by-step explanation:

The equation can be rewritten to ...

  8x = 13n +4 . . . . for some integers x and n

  x = (13n +4)/8

For x to be an integer, 13n must be an odd multiple of 4. Since 13 is an odd number, n=4 will do.

  x = (13·4 +4)/8 = 56/8

  x = 7

__

The graph shows a "trial and error" method of solution. Only values of x less than 13 need to be examined.

Equivalent ratios.

Answer:

[tex]m = -\frac{2}{3}[/tex]

Step-by-step explanation:

Given

[tex]P_1 = (-1,3)[/tex]

[tex]P_2 = (5,-1)[/tex]

Required

Determine and interpret slope

Slope is calculated using:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Where

[tex](x_1,y_1) = (-1,3)[/tex]

[tex](x_2,y_2) = (5,-1)[/tex]

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex] becomes

[tex]m = \frac{-1 - 3}{5 - (-1)}[/tex]

[tex]m = \frac{-1 - 3}{5 +1}[/tex]

[tex]m = \frac{-4}{6}[/tex]

[tex]m = -\frac{2}{3}[/tex]

The above slope is negative and it implies that x increases when y decreases and vice versa.

Answer:

$33

Step-by-step explanation:

55 divided by 5 is 11, so each shirt costs $11. So that means 3 shirts would be $33.

Answer:

$33

Step-by-step explanation:

$33 because 55 dollars divided by 5 shirts is 11 dollars so multiply 11 by 3 and the answer is $33

Answer:

[tex]\frac{x^2}{25} -\frac{y^2}{200} =1[/tex]

Step-by-step explanation:

Recall that the equation of  hyperbola centered at the origin with transverse horizontal axis has the general form:

[tex]\frac{x^2}{a^2} -\frac{y^2}{b^2} =1\\and\,\,\,\, with\\c=\sqrt{a^2+b^2}[/tex]

since we know that a = 5 ,and c = 15,we can solve for b:

[tex]15=\sqrt{5^2+b^2} \\15^2=25+b^2\\b^2=200\\[/tex]

then the equation of the hyperbola becomes:

[tex]\frac{x^2}{5^2} -\frac{y^2}{200} =1\\\frac{x^2}{25} -\frac{y^2}{200} =1[/tex]

Answer:

x = 3

y = 15

Step-by-step explanation:

If △XPS ≅△DNF, their corresponding sides would be congruent. This implies that:

XP ≅ DN

PS ≅ NF

XS ≅ DF

Given that:

XP = 4y - 3

DN = 57

NF = 51

XS = 17x + 3

DF = 54

Therefore:

XP = DN

4y - 3 = 57 (Substitution)

Add 3 to both sides

4y = 57 + 3

4y = 60

Divide both sides by 4

y = 60/4

y = 15

Also,

XS = DF

17x + 3 = 54 (substitution)

Subtract 3 from each side

17x = 54 - 3

17x = 51

Divide both sides by 17

x = 51/17

x = 3
