2/3 x=10
Multiply 3*(2/3 x)=3*10
2x=30
x=15
A is the answer
Answer:
(D) 3x−4
Step-by-step explanation:
<u>Factor Theorem</u>
Given a polynomial P(x) and a linear function x-a, If P(a)=0, then the linear function x-a is a factor of P(a).
In Option A:
In Option B
In Option C
In Option D
We can see that only Option D: 3x−4 gives a result of 0. Therefore, by the factor theorem, it is a factor of the polynomial.

Answer:
C. quadratic
Step-by-step explanation:
You can rightly guess that ballistic motion is described by a <em>quadratic</em> function.
Differences of the y-values are 5.75, 3.25, 0.75, -1.75, -4.25.
First differences are not constant, but form a linear sequence that decreases by 2.5 between each pair. Since second differences are constant, the function is described by a 2nd-degree polynomial function, a <em>quadratic</em>.

<em>Comment on other function types</em>
Linear functions have constant first differences. Exponential functions have exponentially increasing first differences. Logarithmic functions have first differences that increase by smaller and smaller amounts.
