Abiologist has been observing a tree’s height. 1414 months into the observation, the tree was 16.1816.18 feet tall. 1818 months into the observation, the tree was 17.0617.06 feet tall.
let x be the number of months passed since the observations started, and let y be the tree’s height at that time. use a linear equation to model the tree’s height as the number of months pass.
a. this line’s slope-intercept equation is
b. 2828 months after the observations started, the tree would be feet in height
c. months after the observation started, the tree would be 26.0826.08 feet tall.

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
