I think the answer might be A and D
Answer:
slope is the rate at which a function progresses. y intercept a point that passes through they x axis when it is 0. ex) (0,9)
equation written as y=ax +b
b = y intercept
ax = slope
ax = y2-y1/x2-x1
take 2 random points
(0,3) (-2,0)
slope : 0-3/-2=0 = -3/-2 = 3/2
y intercept = 3 because x = 0 and y =3
<u>equation = y =3/2x + 3</u>
Step-by-step explanation:
Answer:
No. It is not.
Step-by-step explanation:
Dividing 5x³+21x²-40x-15 by 5x+4 gives x²+5x-4 with a remainder. Which means, 5x+4 is not a factor of 5x³+21x²-40x-15
Answer:
n = -7
Check:
-4 - 3 + 5 + 4 - 3 + (-7 ÷ -7) = 0
-1 - 7 ÷ -7 = 0
-1 + 1 = 0
0 = 0
Evaluate 3x for x = −2, x = 1, and x = 3. Question 18 options: A) 1∕3, 0, 9 B) 1∕9, 3, 27 C) 9, 3, 27 D) 1∕9, 9, 27

Answer: B) 1/9, 3, 27
Step-by-step explanation:
Here, we need to evaluate 
for 
So, we substitute values of x in the given function.
At x= -2, we have
![3^{-2}=\dfrac{1}{3^2}=\dfrac{1}{9}\ \ \ [\because\ a^{-n}=\dfrac{1}{a^n}]](https://tex.z-dn.net/?f=3%5E%7B-2%7D%3D%5Cdfrac%7B1%7D%7B3%5E2%7D%3D%5Cdfrac%7B1%7D%7B9%7D%5C%20%5C%20%5C%20%5B%5Cbecause%5C%20a%5E%7B-n%7D%3D%5Cdfrac%7B1%7D%7Ba%5En%7D%5D)
At x= 1, we have
At x= 3
So, the values of for
Thus, the correct answer is B) 1/9, 3, 27
