Answer:

F. \frac{3}{4}

Step-by-step explanation:

Constant of proportionality, k, = \frac{y}{x}

The ratio of each given of values on the table will give you the same value, which represents k.

Thus, using the pair, (2, 1.5), k can be calculated as follows:

k = \frac{y}{x} = \frac{1.5}{2}

Multiply the numerator band denominator by 10 to eliminate the decimal point.

= \frac{1.5*10}{2*10} = \frac{15}{20}

Simplify

k = \frac{3}{4}

kramer
Y + 2 = -2(x - 5)

Simplify.

y + 2 = -2x + 10

Subtract 2 from both sides.

y = -2x + 10 - 2

Simplify.

y = -2x + 8 → Slope-intercept form

Our answer is the second option : y=-2x+8

~Hope I helped!~

Given the functions f(x) = 3(0.56)^x and g(x) = 6(4)^x
rodikova [14]
A)  f(x) is decreasing because the base is less than 1.
      0.56 is close to 0.5, so its like saying that you are taking half each time, therefore the value is getting smaller.

g(x) is increasing because the base is greater than 1.
you are multiplying by 4 each time, making the value bigger.


B )  The y-intercept is where x=0.
      Anything to the '0' power is 1. Therefore the y-intercept is equal to the coefficient in front of each function.
    f(x) = 3 ,   g(x) = 6


C)  Just plug in x=4 to each function in a calculator.
 f(4) = 0.295
g(4) = 1536

Which represents a measure of volume?<br> O 5 cm<br> O 5 square cm<br> 05 cm<br> 05 cm
Elena-2011 [213]

Answer:

a) 5cm^{3}

Step-by-step explanation:

Bodies have three dimensions (width, height and depth). Measuring volume is calculating the number of cubic units that can fit inside.

When raising to 3, these dimensions are included and therefore  5cm^{3} is a measure of volume.

mylen [45]

Answer:

up to $338.18

Step-by-step explanation:

Use the compound amount formula:

A = P(1 + r/n)^(n*t), where r is the interest rate as a decimal fraction and n is the number of compounding periods per year.

Here, A = $300(1 + 0.04/12)^(12*3), or

          A = $300(1.0033333)^*36, or

          A = $300(1.127) = $338.18

Nina will be able to spend up to $338.18 on a new bike.

How can you verify that the solution to a proportion is correct?​
xxTIMURxx [149]

<em>Answer:</em>

<em>In problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. To find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.</em>
