Answer: 121
Step-by-step explanation:
Take half of the coefficient of x: It is 3, and half that is 3/2.
Then <span>x^2+3x=6 becomes:
</span><span> x^2+3x + (3/2)^2 =6 + (3/2)^2, and
(x+3/2)^2 = 6 + 9/4
You were not asked to solve the equation, but why not do it for the practice?
</span>Solve (x+3/2)^2 = 6 + 9/4 for x. There will be 2 values.
Im pretty sure the answer is c) 136
Answer:
Step-by-step explanation:
Put in the form of y = Ax + B
x + 2y = 10
2y = -x + 10
y = -½x + 5
has a slope of -½ and a y intercept of 5
-x + 4y = 8
4y = x + 8
y = ¼x + 2
has a slope of ¼ and a y intercept of 2
Answer:
Basic wage rate = $9.375 per hour
Step-by-step explanation:
Given :
Fortnight wage = $750
Basic week, hours worked per week = 40 hours
Weekly basic wage rate :
Fortnight = 2 weeks
Hence, weekly wage = fortnight wage / 2 = 750 /2 = $375
Weekly basic wage rate = $375 / Number of hours worked per week = $375 / 40 = $9.375 per hour
