Answer:
0
Step-by-step explanation:
slope= gradient
Gradient= Y2 - Y1 / X2 - X1
= -15-(-15)/-7-19 , = -15+15/-7-19
= 0
Answer:
Yea i think it is the first one
Step-by-step explanation:
Let 21 = Hypotenuse Let 15 = One leg on the y-axis.
Draw triangle. a^2+b^2 = c^2
a^2 = c^2 - b^2 a = sqrt(c^2-b^2)
sqrt(21^2 - 15^2) = ~14.7 ft

Answer:
the answer to your questions are below
Step-by-step explanation:
1.-
x = 3x - 60
3x - x = 60
2x = 60
x = 30
A = 30
2.-
- x + 26 = 2x - 10
2x + x = 26 + 10
3x = 36
x = 36/3
x = 12
D = 2(12) - 10
D = 24 - 10
D = 14
3.-
5x + 10 = 7x - 12
7x - 5x = 10 + 12
2x = 22
x = 22/2
x = 11
4.- 4x + 7 = 5(x - 4)
4x + 7 = 5x - 20
5x - 4x = 7 + 20
x = 27
5.- 6(x - 2) = 3x + 30
6x - 12 = 3x + 30
6x - 3x = 30 + 12
3x = 42
x = 14
DHG = 6(14 - 2)
DHG = 6(12)
DHG = 72
