50 points to whoever is right and brainliest. The graph shows a proportional relationship. Which equation matches the graph?​
kirill115 [55]

Answer:

  • B. y = 3x

Step-by-step explanation:

Use one of the points on the graph to find the equation.

Let's take the point (1,3)

<u>We know the proportional relationship is:</u>

  • y = kx, where k is the coefficient of proportionality

<u>Substitute the values from the point and solve for k:</u>

  • 3 = 1*k
  • k = 3

<u>The function is:</u>

  • y = 3x

Correct choice is B

(a) Work out the reciprocal of 1.25
Oxana [17]

Answer:

0.8 OR \frac{4}{5}

Step-by-step explanation:

The reciprocal of any number is the number that it multiplies by to equal 1.

The reciprocal can be found by simply converting the number into a fraction and then 'flipping' the fraction as any number multiplied by its reciprocal is 1.

E.g.

No. X/Y * Y/X (its reciprocal) = 1

\frac{x}{y} *\frac{y}{x} =\frac{xy}{xy} =1

So, to find the reciprocal of 1.25,we should first convert 1.25 to a fraction.

1.25 = 125/100

\frac{125/25}{100/25}=\frac{5}{4}

Now we just flip 5/4 to get our reciprocal:

\frac{4}{5} = 0.8

Test: 0.8 * 1.25 = 1

The reciprocal of 1.25 (\frac{5}{4}) is 0.8 (\frac{4}{5}).

Hope this helped!
