<span>ax + by + c = 0
by = - ax - c
y = -a/b (x) - c/b
so slope = </span>-a/b
answer
-a/b

- f (x) = 3x² + x
- Find f (-5).

Given,
Now, we have to find f (-5). To find this, we just need to substitute -5 in the place of x.
So,

Answer:
x= 2
z = 106
Step-by-step explanation:
By the definition of vertically opposite angles,
(10x + 54)° = 74° [Pair of opposite angles made by two intersecting lines]
10x = 74 - 54
10x = 20
x = 2
z° + 74° = 180° [Pair of supplementary angles]
z = 180 - 74
z = 106
The answer will be 19/100 . because the 19 is in the hundredths place
