Answer:
x = -4/7, y = 2/7
Step-by-step explanation:
Given: f(x) = 3x + 2 and g(x) = - 4x - 2
The point of intersection of the two functions is the point at which both functions intersect. We have to solve the functions simultaneously to get the solution.
f(x) = y = 3x + 2
y = 3x + 2 (1)
g(x) = y = -4x - 2
y = -4x - 2 (2)
Subtract equation 2 from equation 1:
0 = 7x + 4
7x = -4
x = -4/7
Put x = (-4/7) in y = 3x + 2:
y = 3(-4/7) + 2 = -12/7 + 2 = 2/7

in google just type "decimal to fraction calculator" and the first one should do it. hopefully it helped
Pythagorean theorem
x^2 + 5^2 = 10^2
x^2 + 25 = 100
x^2 = 75
x = +sqrt(75), -sqrt(75) = +5sqrt(3), -5sqrt(3)
Answer:
10cm
Step-by-step explanation:
Assuming the shape is a rectangle since it's already stated that it's a parallelogram, and the area is stated, we can use the Pythagorean theorem to find the length
, where c will be the length
isolate c
substitute for a and b
