Answer:

perpendicular

Step-by-step explanation:

If 2 lines are parallel then their slopes are equal

If 2 lines are perpendicular then the product of their slopes = - 1

Here

- \frac{9}{5} × \frac{5}{9} = - 1

Then the 2 lines are perpendicular

Charra [1.4K]

Answer:

True

Step-by-step explanation:

First statement

[a b c | d][x]

[a b c]x=d

ax+bx+cx=d

Second statement

Ax=d

Given that A = [a b c]

[a b c]x=d

ax+bx+cx=d

ax+bx+cx=d

Then, they are going to have the same solutions

Simplify the rational expressions. State any excluded values. X^2-4/2-x
tatiyna

Answer:

-x-2;  x\neq2

Step-by-step explanation:

\frac{x^2-4}{2-x}-->

\frac{(x-2)(x+2)}{(2-x)} -->

-(x+2); x CAN'T equal 2, because the denominator of the original fraction would be 0, which would make the term undefined.

Step-by-step explanation:

, open the bracket

3=28-14u-6u

Collect like terms

3-28=-14u-6u

-25 =-20u

Divide both side by -20

u=-25/-20. Minus sign will cancel each other and reduce to the lowest term

u=5/4

Suppose that a local trout population exhibits exponential growth by doubling every 4 years. Considering that the initial popula
antoniya [11.8K]
Okay, so this is just a basic multiplication problem. first, we need to divide to figure out how much the trout population grows after 1 year. If it doubles in 4 years, then it will rise by a quarter each single year. So to put that in terms of fractions, then for every year, the equation would be 250x1/4. So then we do the equation, coming up with 62.5. This means that the population rises roughly 63 fish a year. So after 1 year, you will have roughly 313 fish. (312.5 to be exact). Then to get that by ten years, we can just multiply the number that we got for one year by ten. 62.5x10=625. So then we add the 250 original trout, and 250+625=875. So after 10 years, there will be 875 trout.
