Answer:
Step-by-step explanation:
(-4,-23) , (-2,-11)
slope = (-11 - (-23) / (-2 - (-4) = (-11 +23) / (-2 + 4) = 12/2 = 6
y = mx + b
slope(m) = 6
(-4,-23)...x = -4 and y = -23
now we sub and find b, the y int
-23 = 6(-4) + b
-23 = -24 + b
-23 + 24 = b
1 = b
so ur equation is : y = 6x + 1....with ur slope being 6 and ur y int being 1 or (0,1)
** just so you know, instead of working out the y= mx + b and finding ur y int, u could have just looked at ur points...ur y int is when x = 0...and u have a point (0,1)....meaning ur x is 0....making 1 ur y int.
Hello there!
To find the zeros or the roots of a function, you just need to set the function equal to 0 then solve for x.
f(x) = (x + 4)² - 9
Set function equal to 0
(x + 4)² - 9 = 0
x² + 8x + 7 = 0
Now we can factor the left side
(x + 1)(x + 7) = 0
Then set factors equal to 0
x + 1 = 0 or x + 7 = 0
x = 0 - 1 or x = 0 - 7
x = -1 or x = -7
Thus,
The zeroes of the function are -1 and -7
Let me know if you have any questions. As always, it is my pleasure to help students like you!
The answer is -2 I think haha
Answer:
6 more times
Step-by-step explanation:
First remember 75, 27 away from 102.
BUT hes getting more each day... 4.5 x 6 = 27
which means he will have to visit 6 more times!
:D
