Answer:
A straight line
The gradient is -b/a
The y-intercept is at c/b
The x-intercept is at c/a
Answer:
(x+2)(x+8)=0
Step-by-step explanation:
the first term x² can only be factored by (x) times(x), and the last term 16 has factors of 16&1, 4&4 or 8&2. only 8 &2 have a sum of 10x (the middle term) so
(x+2)(x+8)=0
Answer:
<u>The function is:</u>
<u>According to data in the table we have:</u>
- f(1) = 3 ⇒ a(1)ⁿ = 3 ⇒ a*1 = 3 ⇒ a = 3
- f(2) = 12 ⇒ 3*2ⁿ = 12 ⇒ 2ⁿ = 4 ⇒ n = 2
<u>Since we found the values of a and n, the function becomes:</u>
<u>The number of infected to the tenth day:</u>
Answer:
B. Kilograms
Step-by-step explanation:
Answer:
A. x^2 + 3x + 2
D. 3x^4 + 4x^3 - 3x^2 - 1
E. 3t^3 + 3t^2 + 2t
Step-by-step explanation:
Standard form is where the equation is set up so that the exponents decrease from left to right, and where you put a number with no variable or exponent last.
