You have to first subtract seven from five to get -2. your equation will now be x over four equals negative two. multiply the four by negative two and you'll get -8 equals x
Answer: the answer is 0.32
Step-by-step explanation: first then
Answer:
48
Step-by-step explanation:
You multiply by 2 each time
The first line equation: y = -2/7x - 5; m1 = -7/2
The second line passes through (2,4) and is perpendicular to the first line.
Therefore,
The gradient of first line = -1/m1 = -1/(-2/7) = 7/2
Then, the equation of the second line is;
y = 7/2x+b
Substituting for the coordinates given;
4 = 7/2(2)+b
4 = 7+b
b = 4-7 = -3
Therefore, the equation of the second line is;
y = 7/2x - 3
In standard form, the equation this equation can be written as:
y(2) = 7x - 3(2)
2y = 7x - 6
7x -2y - 6 = 0 -----> standard form.
