Ac is 7 because it is a right angle
Answer:
x = 3, and y = 2
Step-by-step explanation:
2x + 3y = 12 -------- (1)
y = x - 1 ---------------(2)
Substitute value of Y in (2) in (1)
2x + 3(x-1) = 12
2x + 3x - 3 = 12
5x - 3 = 12
5x = 12 + 3
5x = 15
x = 15/5
x = 3
Put the value of x in equation 2
y = x-1
y = 3 - 1
y = 2
Therefore, x = 3, and y = 2

Answer:
5x+4y=85-
Slope = -2.500/2.000 = -1.250
x-intercept = 85/5 = 17
y-intercept = 85/4 = 21.25000
2x+3y=41-
Slope = -1.333/2.000 = -0.667
x-intercept = 41/2 = 20.50000
y-intercept = 41/3 = 13.66667
Answer:
k = 4
Step-by-step explanation:
In order for the claim to be true, (x-3) must be a factor of each of the terms in the first expression. That is, you must have that expression factor as ...
(x -3)(2x +5) +(x -3)(x +7)
Factoring out (x -3), we get ...
= (x -3)(2x +5 +x +7) = (x -3)(3x +12)
= 3(x -3)(x +4)
The value of k must be 4.
