Answer:
![$ y = 5x - 42 $](https://tex.z-dn.net/?f=%24%20y%20%3D%205x%20-%2042%20%24)
Step-by-step explanation:
The equation of parallel line differ only by their constant.
Hence, the equation of the line parallel to
is nothing but ![$ y = 5x + c $](https://tex.z-dn.net/?f=%24%20y%20%3D%205x%20%2B%20c%20%24)
When a point passing through this line is given we can substitute the point in this line and get the value for
.
The line passes through
.
Therefore, we have: ![$ -2 = 5(8) + c $](https://tex.z-dn.net/?f=%24%20-2%20%3D%205%288%29%20%2B%20c%20%24)
.
Substituting this we get the equation of the parallel line as
.
Answer:
332
Step-by-step explanation:
332 divided by 4 + 75 is 158
Hi
f(x) = g(x) if -x²+3x-2 - ( -x+1) = 0
-x² +3x-2 +x-1 = 0
-x² +4x -3 = 0
To solve, tou have to use the general method of resolution of a quadratic fonction.
To determine if it's has a solution in R, let's calculate Δ
Δ = (4)² - 4 * (1) *(-3)
Δ = 16 +12
Δ= 28
as Δ≥ 0 so the function allow two solution within R
so S 1 = ( -4 +√28) / 2 S 2 = (-4 -√28 ) /2
S1 = ( -4 + 2√7) /2 S2 = (-4 - 2√7) /2
S1 = (2 (-2 +√7) /2 S2 2 (-2 -√7) /2
S1 = -2 +√7 S2 = -2 -√7
So the two function are equal twice. one for x = -2 +√7 and second x = -2-√7
Answer:
Eather one of the answers above
Answer:
D: x < 20
Step-by-step explanation:
-4x + 16 > -64
subtract 16 from both sides because you must isolate x.
-4x + 16 - 16 > -64 - 16
-4x > -80
Then divide -4 on both sides... I believe that when you divide a number by a negative number you must flip the sign...
-4x/ -4 < -80/ -4
x < 20
(negative divided by a negative will result in a POSITIVE.)
Hope this helped... I truly apologize if this is wrong..
