Step-by-step explanation:
Question 1: Calculate the slope, x-intercept and y-intercept of a linear equation, f(x) = 5x + 4 ?
Solution:
Given,
f(x) = 5x + 4
The general form of a linear equation is,
f(x) = mx + c
So,
Slope = m = 5
Substitute f(x) = 0,
0 = 5x + 4
5x = -4
x = −45
The x-intercept is (−45, 0)
Substitute x = 0,
f(x) = 5(0) + 4
f(x) = 0 + 4
f(x) = 4
The y-intercept is (0,4)

Answer:
B)139.5
Step-by-step explanation:
Right-angled triangle formula A=ab/2 so find the area of both triangles left side: 2*9/2=9 right side 5*9/2= now find the area of the rectangle 9*12= add all them together 9+22.5+108=139.5
