Answer:
A
Step-by-step explanation:
Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.
Answer:
infinite number of solutions
Step-by-step explanation:
Given
8(x - 3) = 8x - 24 ← distribute left side
8x - 24 = 8x - 24
The expressions on both sides are equal
Hence any real value of x is a solution
That is there are an infinite number of solutions
Solve like a linear algebra equation
use for slope
the b is intersept
A = bh/2
40 = x(2x)/2
80 = 2x²
40 = x²
x = sqrt40
x = +/- 2sqrt10
Measurement cannot be negative therefore x = 2sqrt10
Height = 2x = 2(2sqrt10) = 4sqrt10
The height of the triangle is 4sqrt10 cm or approximately 12.65cm.
