Answer:

Step-by-step explanation:
1: find the perpendicular gradient - this is the negative reciprocal of the original gradient:

2: Substitute in the coordinate to find the value of c:

3: Put it all together:

You can divide it by 9 and get 231 so 231 times 9 equals 2079
Answer:
x = 24
Step-by-step explanation:
The triangle is split into two similar triangles. They have the same shape but not the same size. To solve, write a proportion.

Cross multiply to solve for x.
56(x+4) = 44.8(35)
56x + 224 = 1,568
56x = 1,344
x= 24
Answer:
<h2>B. i = √(−1)</h2>
Step-by-step explanation:
When (i) is multiplied to itself it = -1
The number (i)is used for imaginary numbers.
Ratio = 1/25
Let, the distance b/w cities on map = x
It would be: 1/25 = x/175
x = 175/25
x = 7
In short, Your Answer would be 7 in
Hope this helps!
