Answer:
x = 6.7
Step-by-step explanation:
legs of a right triangle are 6,3 and hypotenuse be x
using pythagors theorem to find hypotenuse
a^2 + b^2 = c^2
6^2 + 3^3 = x^2
36 + 9 = x^2
45 = x^2
6.70 =x
6.7 =x
k=1 or 3k=3
2k-5k=-3k that's your first side
3*1=3 3*-2k=-6k 3-6k is now your second side you add 6k to both sides and your left with
3k=3 which simplifies down to k=1
Answer:
y = x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 1, thus
y = x + c ← is the partial equation
To find c substitute (5, 1) into the partial equation
1 = 5 + c ⇒ 1 - 5 = - 4
y = x - 4 ← equation of line
