f(x) = (x - 4 )(x - 6) = 0

because you can see when each factor is equal to zero

x - 4 = 0 ⇒ x = 4

x - 6 = 0 ⇒ x = 6

Naddik [55]
Well if you take the room being 20 x 24. Thats 480 feet. But you want how large in 1/2 inch. 1/2 inch is 1/24 of a foot. So if we take 480 feet being 1 and times it by 24. (480 x 24) You get 11,520 half inches. Brainliest would be much appreciated if you feel its deserved.

Yolanda's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Yolanda $5.20 per pound, and t
MAXImum [283]

Answer:

78 pounds

Step-by-step explanation:

Let's say Yolanda makes a pounds of Type A coffee and b pounds of Type B coffee. Since the total number of pounds is 130, we can write the equation:

a + b = 130

We know the cost of Type A coffee is $5.20/lb and the cost of Type B coffee is $4.05/lb, so since the total cost is $586.30, we can write:

5.20a + 4.05b = 586.30

We can now solve the system of equations:

a + b = 130

5.20a + 4.05b = 586.30

Manipulate the first equation by subtracting b from both sides:

a + b = 130

a = 130 - b

Substitute 130 - b for a in the second equation:

5.20a + 4.05b = 586.30

5.20 * (130 - b) + 4.05b = 586.30

676 - 5.20b + 4.05b = 586.30

Move the terms with b to one side:

1.15b = 89.70

b = 78

Thus, Yolanda used 78 pounds of Type B coffee.
