(0,-9);slope=4

Mathematics
1 answer:
cestrela7 [59]3 years ago
8 0
1. y=4x-9
2. y=-3x+1
3. y=x-3
4. y=5x-11
5. y=5/6x-3
6. y=-2x+6

I’m not sure how to explain this but basically, if you have y=mx+b (the answer), the equation used to find that is y-y1=b(x-x1). b=slope

It’s kind of confusing but I’ll use the first question as an example.

So, y+9=4(x-0) You would substitute in your x, y, and slope and solve it from there. It’s a bit confusing at first but once you understand it’s easy.

Hello people can you help me with dis two question
____ [38]

Answer

length = 11 in

width = 6in

2 in = 5m

length =

28m ÷ 5

= 5

remainder 3m

1 in = 2.5

if 2in = 5m

then 2 × 5 = 10

10 + 1 = 11in

width

2in = 5m

15m ÷ 5

= 3

3× 2

=6

Chad and Victoria are playing a game with a quarter and a spinner divided into sixths numbered one through six each player spins
rodikova [14]
The simple way to do this is to multiply the number of outcomes of one object times the number of outcomes in the other object. In this case a quarter has 2 sides, heads and tails. Since the spinner has 6 sections, there are 6 outcomes.


With this we can do, 2x6=12.

Therefore there are 12 outcomes

MARKING AS BRAINLIEST!! Starr if given functions are inverse)!
Kitty [74]

Answer: They are inverses of each other

==========================================================

Explanation:

We'll need to compute h(f(x)) and f(h(x)) to see if we get x each time.

h(x) = 9x-4\\\\h(f(x)) = 9(f(x))-4\\\\h(f(x)) = 9\left(\frac{x+4}{9}\right)-4\\\\h(f(x)) = x+4-4\\\\h(f(x)) = x\\\\

and,

f(x) = \frac{x+4}{9}\\\\f(h(x)) = \frac{h(x)+4}{9}\\\\f(h(x)) = \frac{9x-4+4}{9}\\\\f(h(x)) = \frac{9x}{9}\\\\f(h(x)) = x\\\\

Both composite functions lead to x each time.

The equations h(f(x)) = x and f(h(x)) = x being true means each function is the inverse of the other.
