X= 2 , y= -3 
You have to multiply the second equation by a negative and the you'll get,        -3x-y=-3. the y's cancel out and then you combine the x's and the 5 and the 3 and then x=2 and then you pick one of the two equations and sub in the x and solve for y.

1. x² - 6x + 8
   4*2 equals 8 and if you add 4 and 2 it gives you 6
    -4-2= -6
   =(x-4)(x-2)

3. the answer is A
    if you plug in the points into the equation y=x
    y= 1/2x + 4
given point: (4,6) x=4 y=6
    6= 1/2(4)+4
    6=6

A population of 805 cheetahs decreases by 10% per year. How many cheetahs will there be in the population after 6 years?
Phantasy [73]

Answer:

Step-by-step explanation:

y = a(b)^x

a would represent the initial value.

b would represent the change

x represents the number of years

y = 805(0.9)^6

y = 805(0.531441)

y = 427.8

y =  427 cheetahs

Does anyone know how to do this
bezimeni [28]
You can turn 5 into 10/2 and add to x/2
then you need to use simple algebra to left the x alone in the equation so you need to multiply both sides by 2 so you get
2y=10+x
then you need to subtract both sides a 10 so
2y-10=x
now change the x to f'(x) and y to x so:
f'(x)=2x-10
