Answer:
(-8, 2)
Step-by-step explanation:
set these equations equal to each other
1/2x + 6 = -3/4x -4
5/4 x = -10
x = -10x4/5 = -40/5 = -8
plug this x into one of the equations
y = 1/2 (-8) + 6
y = -4 + 6
y = 2
8 and 2: 8+8+2+2
7 and 3: 7+7+3+3
6 and 4: 6+6+4+4
=20
Answer:
y = x - 1 (third answer choice)
Step-by-step explanation:
From the given we see immediately that the slope of this line is -1. The slope of a line perpendicular to this one is +1, which is the negative reciprocal of -1. The slope-intercept form is y = mx + b. To find b, the y-intercept, we make the following substitutions: m = -1, y = -2, x = -2:
-2 = +1(-2) + b, or +1 = 2 + b, or b = -1
and so the desired equation is y = x - 1 (third answer choice)

Answer:
£103.70
Step-by-step explanation:
Payment per hour = £8.50
Overtime payment = 1.4 × 8.50
= £11.90
Ben worked for 11 hours.
Normal time = 8 hours
Overtime = 3 hours
Total earnings = (8 hours × 8.50) + (3 hours × 11.90)
= £68 + £35.7
= £103.70
Ben earned £103.70 for working for 11 hours
