I don't understand proportional relationship can u help?

Reptile [31]

Answer: I’ll explain it in simpler terms for you. A proportional relationship is one in which two quantities vary directly with each other. Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional. An example of a proportional relationship is simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error. Hope this helps! :D

What Is The Recursive Rule For The Sequence? 1.2, 0.4, -0.4, – 1.2, -2,

nevsk [136]

<h3>Answer:</h3>

$\boxed{\bold{a_n = a_{n-1} -0.8}}$

<h3>Explanation:</h3>

<u>Sequence</u>: 1.2, 0.4, -0.4, – 1.2, -2,...

See that with every next term, the integers are decreasing by 0.8

So, common difference (d) = -0.8

<u>recursive formula</u> : $\sf a_n = a_{n-1} +d$

$\bold a_1 = 1.2,$ $\sf a_n = a_{n-1} + (-0.8)$

In triangle DEF, segment DJ is a perpendicular bisector of side EF. If EJ is 3y-8 and JF is 7y-40, what is the length of JF?

luda_lava [24]

Answer: The length of JF = 16 units.

Step-by-step explanation:

Given: In triangle DEF, segment DJ is a perpendicular bisector of side EF.

i.e. DJ is perpendicular to EF and DJ divides EF into two equal parts EJ and JF. [The perpendicular bisector is a line that is perpendicular to a line segment and splits it into two congruent segments.]

If EJ is 3y-8 and JF is 7y-40.

Then, $3y-8=7y-40$
