Answer:
x intercept is -3
Step-by-step explanation:
We need to find the equation for the line
First we find the slope
m = (y2-y1)/(x2-x1)
= (2- -4)/(6- -3)
= (2+4)/(6+3)
=6/9
= 2/3
The we can write the equation
y= mx+b
y = 2/3x +b
We can substitute in (6,2)
2 = 2/3(6) +b
2 =4+b
Subtract 4 from each side
2-4 =b
b =-2
y = 2/3 x-2
We want to find the x intercept, so set y =0 and solve for x
0 = 2/3x -2
Add 2 to each side
0-2 = 2/3x
Multiply each side by 3/2 to isolate x
-2 *3/2 = 2/3x * 3/2
-3 =x
The x intercept is -3
Answer:
the eldest sister is unconcerned about the journey while the youngest sister thinks something is wrong
The equivalent is 1/12, or approximately 0.83
correct answer is option d.
<u>Step-by-step explanation:</u>
Here, we have The following expression to check Which of the following is a polynomial with roots: −square root of 3 , square root of 3, and 2 :
<u>a. x3 + 3x2 − 5x − 15
</u>
For , ⇒ . So, this isn't the one. We move on further!
<u>b. x3 + 2x2 − 3x − 6
</u>
For , ⇒ = 0 .
For , ⇒ = 0.
For 2 , ⇒ . So, this isn't the one. We move on further!
<u>c. x3 − 3x2 − 5x + 15
</u>
For , ⇒ . So, this isn't the one. We move on further!
<u>d. x3 − 2x2 − 3x + 6</u>
For , ⇒ = 0 .
For , ⇒ = 0.
For 2 , ⇒ = 0.
Therefore, correct answer is option d.
