Answer: c = \frac {d + ab} {a}
Step-by-step explanation:
For this case we have the following equation:
a (c - b) = d
We want to solve the equation for the letter c.
To do this, we apply the distributive property:
ac-ab = d
Then, applying addition property of equality we have:
ac = d + ab
Then applying division property of equality we have:
c = \frac {d + ab} {a}
Answer: y = 3x - 2
the equation is y = ax + b (a ≠ 0)
see in the picture, the line passes through (0;-2) and (2;4)
because the line passes through (0;-2) => b = -2
the line passes through (2;4) => 2a + b = 4
have: b = -2
2a + b = 4
⇔ a = 3
b = -2
=> the equation is y = 3x - 2
Step-by-step explanation:
Plug x = 3 into the first piece to get
2(x+1) = 2*(3+1) = 2*4 = 8
Do the same for the last piece
x^2 - 1 = 3^2 - 1 = 9-1 = 8
So as we approach x = 3 from either the left or right side, the limiting value is 8
The final answer is 8
Convert to slope / intercept form:-
4x + 5y = -2
5y = - 4x - 2
y = -4/5 x - 2/5
the slope of this line is -4/5 and slope of line perpendicular to it is - 1 / -4/5
= 5/4 answer
