Answer:
80+30h
Step-by-step explanation:
Answer:
<h2>The required time is 8 years.</h2>
Step-by-step explanation:
Let, it will take x years to be of same height for these trees.
We know that 1 ft = 12 inches.
8 ft = . 2 ft = 24 inch.
After x years, the height of type A will be (96 + 6x) inch and the height of type B will be (24 + 15x) inch.
We need find the value of x, for which 96 + 6x = 24 + 15x or, 9x = 72 or, x = 8.
Step 2 is wrong and i don't know the other question
To find the x intercept just substitute your y value for 0 then solve for x.
So you get 0= x+3 and then you get x=-3 which is at (-3,0).
Answer:
p(x)=x^4+9x^3-9x+2
p(-3)=(-3)⁴+9(-3)³-9×(-3)+2=81-243+27+2=-133 is you answer
