When two lines are cut by a transversal,if the alternate interior angles are equal in measure then the lines are parallel?
Lerok [7]

Ah what you say is true, yes you've answered your question.

When lines are usually cut by a transversal , the transversal only cuts two parallel lines , therefore any alternate interior angles that you find are equal , the lines are always parallel.

The price of products may increase due to inflation and decrease due to depreciation. Marco is studying the change in the price
mihalych1998 [28]

Answer:

hey

please mark me brainliest

Step-by-step explanation:

f(x) = 0.69 (1.03)^x

in other words TO THE POWER x

that would be 0.69 when x = 0 years, now

0.69 * 1.03 after one year

0.69 * 1.03 *1.03 after two years

0.69 *1.03*1.03*1.03 after 3 etc

It is getting bigger. Every year you increase by .03 x which is 3%

Which graph shows the solution set of the compound inequality 1.5x-1>6.5 or 7x+3<-25
ad-work [718]
For this case we have the following inequations:
 1.5x-1> 6.5
 7x + 3 <-25
 Clearing x from each one we have:
 For 1.5x-1> 6.5:
 1.5x> 6.5 + 1
 1.5x> 7.5
 x> 7.5 / 1.5
 x> 5
 For 7x + 3 <-25:
 7x <-25-3
 7x <-28
 x <-28/7
 x <-4
 The solution set is:
 (inf, -4) U (5, inf)
