Answer:
y=-1/4x-4
Step-by-step explanation:
it simple rise over run: -1 go down one over 4 right or the other way around go up 1 and left 4 either way would work your y intercept is -4 because that is the point crossing the y-axis hope i helped!
Answer: I believe its 138 inches, if 'wrong i'm sowwy.
Step-by-step explanation: It sates to find the height of the was 6 inches less than 12 feet tall, this means were subtracting 6 (less than) into 12 feet. We cant do that until we convert inches into feet. we know that 12 inches is equal to 1 foot.
Easier way to do this is to .. multiply 12 by 12 which is = 144
12 inch = 1 ft
24 inch = 2 ft
SO, 144 - 6 = 138
To convert this into feet we divide 12 into 138 which is 11.5 feet.
Hello there!
A C method : you multiply the A and C -> find the factors of AC that can add up to B. (a² + bx + c)
15a² + 14a - 8
you multiply 15 and -8 = -120
Find the two factors of -120 that adds up to 14.
We could used 20 and -6.
So we can split the original equation to this:
15a² + 20a - 6a - 8
Now, we use grouping method.
Let's group 15a² + 20a and -6a - 8.
15a² + 20a can be factored like this :
5a(3a + 4)
-6a - 8 can be factored like this :
-2(3a + 4)
So it is 5a(3a + 4) × -2(3a + 4)
We can simplify this into this :
(5a - 2)(3a + 4)
So your final answer is (5a - 2)(3a + 4).
Hope this helped! :)
