We determine line m as follows:
*First, by theorem we have the following:

Here m1 & m2 are the slopes of two perpendicular lines. For all lines that are perpendicular that is true, so we calculate the slope of line m using the slope of the function given [Which has a slope of 7/4]:

So, the slope of line m is -4/7. Now, using this slope and the point (-1, 4) we replace in the following expression:

Here x1, y1 & m1 are the x-component of the point, the y-component of the point, and the slope of the line respectively, so we replace and solve for y:


And that last function of y is the line m.

Answer:
35
Step-by-step explanation:
70 × 0.5 = 35
or
50% = 1/2
so
70/2 = 35
Answer:
B
Step-by-step explanation:
Because 16 + 2.50 is less than 25 + 0.25x
Answer:
The only way of getting to 10 using 2x it should mean that x = 5
2 * 5 = 10
