Answer:
question 3 would be C. and question 4 would be A.
Step-by-step explanation:
Answer:
x= 5.55 and 0.45
Step-by-step explanation:
Quadratic Equation = (-b±√b²-4(a)(c))÷2(a)
Get equation = to 0 by subtracting the 3 on the right side of the = sign
2x² - 12x + 5
Identify the variables
a=2
b=-12
c=5
Put them into the quadratic equation
(-(-12)± √-12² - 4(2)(5))÷2(2)
Simplify
(12 ±√144 - 40)÷4
(12±√104)÷4
Now split into 2 equations (one with addition one with subtraction) because of the ± then continue simplifying
(12 - √104)÷4 (12 + √104)÷4
(12 - 10.198039)/4 (12 + 10.198039)/4
5.54950975 0.45049025
Round
5.55 0.45
Answer:
Step-by-step explanation:
7 = (y+2)/(x-1)
Parallel lines have equal slopes.
You can "massage" the form into any form you need.
Answer:
The expression y = 4.85g + 0.83s can be used to determine the total cost.
Step-by-step explanation:
Given that:
Cost per pound of granola bars = $4.85
Cost per pound of sugar = $0.83
Let,
y be the total cost.
According to given statement;
y = 4.85g + 0.83s
Hence,
The expression y = 4.85g + 0.83s can be used to determine the total cost.
