The equation of a linear function: y = mx + b
x = y - 3 → y - 3 = x <em>add 3 to both sides</em>
y = x + 3 <em>it's a linear function!</em>
y = x³ + 2 NOT, because we have x³
y = 6x² NOT, because we have x²
y = 2/(3x) NOT, because x is in denominator.
Answer:
t=7seconds or 5seconds
Step-by-step explanation:
s=-16t^2 +192t
let s=560ft
560=-16t^2 +192t
16t^2 -192t+560=0
16(t^2-12t+35)=0
(t^2 -12t +35)=0
factoring it ,it will give
(t-7)(t-5)=0
solving for t
t-7=0 or t-5=0
t=7s or t=5s
<h3><u>Question</u> :-</h3>
Is (x-2) is a factor of x³-3x²-x +7 –
<h3><u>Explanation</u> :-</h3>
We are given –
- Polynomial function, P(x) = x³-3x²-x +7
- In order to check if x - 2 is a factor of x³-3x²-x +7 or not, we must show that P(2) = 0.
Now Put x = 2 into the polynomial –
- Since the value of the polynomial function st x = 2 is not Zero (0). Henceforth, ( x - 2) is a factor of x³-3x²-x +7.

Answer:
Sam's student council spent $39 on backpacks + paper and pens.
Step-by-step explanation:
They bought 3 backpacks for $7 each. 3 x 7 = $21.
They also filled those backpacks with paper and pens costing $6 each. 3 backpacks x $6 = $18.
Now, add the two prices.
18 + 21 = 39
