Answer:
a = 12m
Step-by-step explanation:
In order to solve this problem we will need to know the Pythagoras theorem that states that in a right angled triangle the square of the hypotenuse (the side opposite to the right angel) is equal to the sum of the squares of the other two sides. This theorem can be written as an equation....

Now we can see that we can easily find the missing value by using this theorem. We just have to substitute the values. And we get the following







Krista will have more money in 2 years time than Nick and she will get $14.05 more than Nick. Hope this helps.
Answer:
C. (1, -3)
Step-by-step explanation:
Plug in the x to get the y in the equation. The point must fit the formula.
Plug in C. (1, -3), in which x = 1, y = -3:
(-3) = 2(1) - 5
Simplify:
(-3) = 2(1) - 5
-3 = 2 - 5
-3 = -3 (True).
C is your answer.
~
(-1,1)(1,4)
slope = (4 - 1) / (1 - (-1) = 3/(1 + 1) = 3/2
y = mx + b
slope(m) = 3/2
use either of ur points....(1,4)...x = 1 and y = 4
now sub and find b, the y int
4 = 3/2(1) + b
4 = 3/2 + b
4 - 3/2 = b
8/2 - 3/2 = b
5/2 = b
equation is y = 3/2x + 5/2...but we need it in standard form
y = 3/2x + 5/2
-3/2x + y = 5/2.....multiply both sides by -2
3x - 2y = -5 <==== ur standard form equation
