the quotient of a number and fifteen

Explanation:

Locate the point that has x = -3 as its x coordinate. The y coordinate is the output of the function when we use this x value. So the point (-3,-7) means that f(-3) = -7. As another example, f(2) = 3.

Answer:

[tex](x,y) = (2.-2)[/tex]

Step-by-step explanation:

Given

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

[tex]-2x + y = -6[/tex]

Solving (a): Graph the equations

See attachment for graph

Solving (b): The solution

This is the point of intersection between both lines

From the attached graph, the point of intersection is:

[tex](x,y) = (2.-2)[/tex]

Answer:

Part A is 34

Part B is 2

Step-by-step explanation:

This question did provide some clues to answer this question. Every week, the area covered by the algae is multiplied by 2^1.

To find the area cover increase by the algae per day, the exponent should be divided by 7 since there are 7 days in a week. Hence, every day, the area covered by the algae multiplies by 2^(1/7). In other words, 1 day after the algae was spotted, the area is 12.5 * 2^(1/7), which answers part B.

10 days after the algae was spotted, the area covered by the algae is 12.5 * 2^[(1/7)*10] = 33.6475... , which rounds up to 34 and answers part A.

Answer:

  38.13 = 12 +4.75h

  5.5 hours

Step-by-step explanation:

(a) The charge (c) for renting a bike for h hours is ...

  c = helmet charge + hourly charge × hours

  c = 12.00 +4.75h

To find the number of hours when the charge is 38.13, we would use the equation ...

  38.13 = 12.00 +4.75h

__

(b) To solve this 2-step linear equation, we first subtract the constant

  26.13 = 4.75h

then we divide by the coefficient of the variable.

  26.13/4.75 = h ≈ 5.5

Amanda rented the bike for 5.5 hours.

Additional comment

The result of the division is a long repeating decimal that starts off 5.50105263.... The instructions tell you to round this to the nearest tenth: 5.5. It helps to follow instructions.

Answer:

  140°

Step-by-step explanation:

Angles 1 and 3 are "corresponding" angles, so are congruent.

  ∠1 = ∠3

  20x +60 = 30x +20

  40 = 10x . . . . . . . . . . . . subtract 20x+20

  4 = x . . . . . . . . . . . . . . divide by 10

  ∠1 = 20x +60 = 20(4) +60 = 80 +60

  ∠1 = 140°

Answer:

140°

Step-by-step explanation:

Angle 1 and angle 3 are corresponding angles ;

Corresponding angles are equal ;

Hence,

Angle 1 = Angle 3

20x + 60 = 30x + 20

Collect like terms

20x - 30x = 20 - 60

-10x = - 40

x = 4

Angle 1 is thus :

20x + 60 ; x = 4

20(4) + 60

80 + 60

= 140°

Explanation:

f(x) is the outer function, so the final output -8 corresponds to f(x)

We see that f(-4) = -8 in the first column of the table. I'm starting with the output and working my way backward to get the input. So we started with -8 and worked back to -4.

Then we move to the g(x) function to follow the same pattern: start with the output and move to the input. We start at -4 in the g(x) bubble and move to 3 in the x bubble.

In short, g(3) = -4

So,

f(g(x)) = f(g(3)) = f(-4) = -8

We see that x = 3 leads to f(g(x)) = -8

Answer:

x = 13.48

Step-by-step explanation:

Given that,

Angle, [tex]\theta=26^{\circ}[/tex]

base, b = x

Hypotenuse, H = 15

We need to find the measure of x. It can be solved using trigonometry i.e.

[tex]\cos\theta=\dfrac{b}{H}[/tex]

Put all the values,

[tex]\cos(26)=\dfrac{x}{15}\\\\x=15\times \cos(26)\\\\x=13.48[/tex]

So, the value of x is equal to 13.48.

35 cows / 15 cows = 2.3333

21 goats x 2.333 = 49

The answer is 49

Answer:

Number of Goats = 49

Step-by-step explanation:

Let the number of goats be = x

 Goats          Cows

   21                15

    x                 35

[tex]\frac{21}{x} = \frac{15}{35}\\\\15 \times x = 21 \times 35\\\\x = \frac{21 \times 35}{15} = 7 \times 7 = 49[/tex]

49 goats eat as much as 35 cows.
