Suppose y varies inversely with x. Write an equation if y=7 when x=-4
luda_lava [24]

Answer:

y = -28 ÷ x

Step-by-step explanation:

The standard format of a inversely proportional equation goes by the format of y = k ÷ x. The question asks us to write an equation if y = 7 when x = -4 and y varies inversely with x.

So we substitute the values y = 7 and x = -4 in the equation y = k ÷ x

K = constant, we have to work this out

7 = k ÷ -4

7 × - 4 = k

k = - 4 × 7

k = -28

k = -28 So then we put this back into the original y = k ÷ x to find our final equation which is y = -28 ÷ x

What is the measure of angle x? m<x = ?
Ainat [17]
Hey there! :)

The total measure for triangles is 180°

You already know 2 angles. Add both angles and subtract from 180 to find x

37 + 82 = 119

180 - 119 = 61

m∠x = 61°

Hope this helps :)

11. Write 5 equivalent fractions for<br>• 6/7.​
almond37 [142]

\huge{\boxed{\frac{12}{14}}} \huge{\boxed{\frac{18}{21}}} \huge{\boxed{\frac{24}{28}}} \huge{\boxed{\frac{30}{35}}} \huge{\boxed{\frac{36}{42}}}

One really simple way to find an equivalent fraction is just to multiply the numerator and denominator.

For example, for the first answer, \boxed{\frac{12}{14}}, I simply multiplied the numerator and denominator each by 2.  This gives you an equivalent fraction.

You can then continue with this process using numbers such as 3, 4, 5, and 6 as your multiplication factor.
