Answer:

1/2zw

Step-by-step explanation:

The triangle formula is 1/2 x base x hight.

I'm this triangle the z is representing the base and the w is representing the hight.

10x4a=40a

10x9=90

-8x2=-16

-8xa=-8a

40a-8=32a

90-16=74

32a+74

as you should already know, to get the inverse of any relation we start off by doing a quick switcheroo on the variables and then solve for "y".

[tex]\stackrel{f(x)}{y}=\cfrac{3}{4}x+9\implies \stackrel{quick~switcheroo}{x=\cfrac{3}{4}y+9}\implies x-9=\cfrac{3y}{4}\implies 4x-36=3y \\\\\\ \cfrac{4x-36}{3}=y\implies \cfrac{4}{3}x-12=\stackrel{f^{-1}(x)}{y}\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]

The solution to a system of equations is at the point of intersection of the 2 lines.

The lines are parallel and never intersect.

Tgus the system has no solution

Answer:

1/2 or 2/4

Step-by-step explanation:

The total amount of pieces is 4. The dot is at the second piece. Therefore, it is at 2/4. We can simplify 2/4 to 1/2 by dividing both the numerator and the denominator by 2.

Answer:

-2x^3 + 1/7x - 1

Step-by-step explanation:

Answer:

-2x*3+x/7-1

Step-by-step explanation:

In standard form for polynomials, you would put the monomial with the highest degree in the front first, then the second most, and so on. -2x*3 has a cubic degree, so it will come first. x/7 has a constant degree, so it will come next. Finally, -1 has no degree, so it will come last.

Answer:

Using two of the points on the line, you can find the slope of the line by finding the rise and the run. The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run: Slope =riserun Slope = rise run .

Answer:

1/9 is the probability that its red chip.

Step-by-step explanation:

total chips = 14 + 10 + 12 = 36 chips

first probability = 12/36 = 1/3

second probability = 12/36 = 1/3...........total remains same, 36 as its replaced

therefore probability =  1/3 * 1/3 = 1/9

Answer:

6 and 19 which is bridgets and 114 and 3 which you know is Coles

Answer:

bridget in week 13 will have 117 books and Cole in week 3 will also have 117 books

Step-by-step explanation:

find total books in a week

Bridget =6+3=9

cole= 38+1=39

find lcm

9={3×3}

39={3×13}

lcm={3×3×13}

=117

for Bridget

117÷9 =13 weeks

for cole

117÷39

3 weeks

Answer:

4321 people

Step-by-step explanation:

Since the population is modeled by exponential growth, we would need to determine the approximate growth factor by using the formula [tex]y=ab^x[/tex] where [tex]a[/tex] is the initial population, [tex]b[/tex] is the growth factor, and [tex]x[/tex] will be the number of years after 1994:

[tex]y=ab^x\\\\1519=1256b^2\\\\\frac{1519}{1256}=b^2\\\\b\approx1.0997[/tex]

Therefore, since 13 years after 1994 is 2007, then we have:

[tex]y=1256(1.0997)^x\\\\y=1256(1.0997)^{13}\\\\y\approx4321[/tex]

Therefore, the population of Amuel in 2007 was approximately 4321 people.

Answer:

We can use the ratio of proportional sides to help us solve the question.

m        4

---- = -----

3         2

Using cross products

2*m = 4*3

2m = 12

Divide each side by 2

2m/2 = 12/2

m = 6

The value of m that makes the triangles similar is 6

Answer:

17.6 miles

Step-by-step explanation:

5 divided by 8 is 1.6

1.6 times 11 is 17.6

Answer:

the first one : 4/5 + 3/8

the third one : 7×sqrt(5) - sqrt(245)

the 4th one : 4×sqrt(7) × 2×sqrt(7)

Step-by-step explanation:

per definition, the set of rational numbers is the set of all integers and fractions.

the first answer is simply a prime example of fraction operation, and the result is therefore a fraction again.

the 3rd answer delivers 0, because

sqrt(245) = sqrt(49×5) = 7×sqrt(5). this is a rare occasion where an operation with a non-rational number still delivers a rational result.

the 4th answer squares the square root of 7 creating 7, which creates overall an integer and therefore rational result.

the other options contain at least one number that is not rational and will not be converted or neutralized by the operation.

and the sum and product of a rational with a non-rational number is always non-rational.

sqrt(100) + sqrt(5) = 10 + sqrt(5).

as 5 is not a square number, its square root contains an infinite number of digits after the decimal point without any repeating pattern. this is a real number, not a rational number.

pi is per definition not rational (same thing as for sqrt(5) : infinite number of digits after the decimal point without any repeating pattern).

Answer:

$ 40.82

Step-by-step explanation:

the sum of the three numbers is 40.82.

Answer:

Angle A = 180

Step-by-step explanation:

180=7x+40

Subtract 40 from both sides

140 = 7x

Divide 7 from both sides

20=x

Substitue 20 in for x

7(20)+40

140+40 = 180

Answer:

x = 18

< A = 166

Step-by-step explanation:

Angles A and B are corresponding angles, therefore they have the same measure. Using this information, you get the following equation:

7x + 40 = 3x + 112

-3x         - 3x

4x + 40 = 112

     - 40   - 40

4x = 72

Divide both sides by 4.

x = 18

Solve for A:

7(18) + 40 = 166

Answer:

  x ≈ 3.9

Step-by-step explanation:

Call the segment shared by the two triangle "y". The Pythagorean theorem tells you ...

  sum of squares of sides = square of hypotenuse

  y² +6² = 10²

  x² +7² = y²

Substituting for y² using the second equation, we get ...

  x² +7² +6² = 10²

  x² = 10² -7² -6² = 100 -49 -36 = 15

Taking the square root, we find ...

  x = √15 ≈ 3.9
