finlep [7]3 years ago
3 0

Answer:

Two

Step-by-step explanation:

x² + 4 = 4x + 1

x² - 4x + 3 = 0

x² - 3x - x + 3 = 0

x(x - 3) - (x - 3) = 0

(x - 3)(x - 1) = 0

x = 1, 3

y = 4(1) + 1 = 5

y = 4(3) + 1 = 13

Two solutions: (1,5) (3,13)

Phil is going to store to buy a hat and a coat. The coat cost 3 times as much as the hat. His mom tells him that he cannot spend
Oduvanchick [21]

Answer:

Step-by-step explanation:

Phil is going to store to buy a hat and a coat.

Let $x represent the cost of the cos of the hat. The coat cost 3 times as much as the hat. It means that the cost of the coat will be 3×x = $3x

His mom tells him that he cannot spend more than $120. Assuming he spends exactly $120. It means that

3x + x = 120

4x = 120

x = 120/ 4 = 30

The hat costs $30

The coat costs 30×3 = $90

The most he can spend on a coat is $90 since he cannot spend more than $120
