Factors of 3 that add up to 4:
(x + 3)(x + 1)
Set them to 0 and solve for x
<span>x = -3 </span>
<span>x = -1</span>
Answer:
$8 for 3 pounds
cost for p pounds: 3.50p - 2.50
Step-by-step explanation:
Cost of 3 pounds:
Original cost = Cost per pound x 3
= 3.50 x 3
= 10.50
Coupon = 2.50
Final cost = Original cost - Coupon
= 10.50 - 2.50
= $8
Cost of p pounds:
Original cost = Cost per pound x p
= 3.50 x p
= 3.50p
Coupon = 2.50
Final Cost = Original Cost - Coupon
= 3.50p - 2.50
Answer:
a) 10*10 inch, b)yes, c) 15
Step-by-step explanation:
a)
we need to calculate the Greatest Common Factor between 30 and 50

then, the square tiles will be 10 inch *10 inch
b) it will change because they don't need to have the largest slab possible so they will use any other comon factor with a size they consider correct for the cheese.
c)

15 squares of 10inch*10inch of cheese could be cut.
Using linear functions, it is found that the number of electronics that you need to sell for a larger income in option A is x > 200,000.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
Considering the <u>base salaries as the intercept and the commissions as the slope</u>, the functions are given by:
To produce a larger income in option A, it is needed that:
A(x) > B(x).
Hence:
10000 + 0.09x > 20000 + 0.04x
0.05x > 10000
x > 10000/0.05
x > 200,000
