Hi there!
The equation of any line perpendicular to

is

Therefore, in this situation, the formula of the line would be

Given that the line passes through the point (6, 4) we get



Therefore, the equation of the line that is perpendicular to 3x + 9y = 7 and passes through (6, 4) is
Answer:
The 1st and the last options
Step-by-step explanation:
5:10 can be simplified to 1:2. Other figures that fit this ration are A, or 2:4, and D, or 4:8.
Answer: Tigers: Linear Function
Narwhals: Linear Function
X 3x+7 y (x, y)
1 3(1) +7 10 (1,10)
2 3(2) +7 13 (2,13)
3 3(3) +7 16 (3,16)
4 3(4) +7 19 (4,19)
According to the picture, you can assume that angle X is congruent to angle Y due to their triangle shape. Here is the work:
1. Set the equations equal to one another: 4x-8 = 2x
2. Move the variables to get the "x" values on one side: 2x = 8
3. Divide by 2 to get "x": x = 4
4. Plug in "x" into the Angle X equation: 4(4)-8 = angle x....16-8....8
Angle X is 8 degrees. Hope this helped :)
