Answer:
y = x² - 10x + 41
Step-by-step explanation:
The standard form of a quadratic is ax² + bx + c : a ≠ 0
Given
y = (x - 5)² + 16 ← expand (x - 5)²
= x² - 10x + 25 + 16
= x² - 10x + 41 ← in standard form
Answer:
y = 3x - 4
Step-by-step explanation:
The line crosses the y-axis at -4. The line goes 3 down and 1 left.
If you square 3, you get 9, and if you "take the square root of 9", you get 3
Answer:
6 hot dogs, 2 drinks
Step-by-step explanation:
let y = number of hot dogs
let x = number of drinks
system:
y = 3x
4.5y + 2.25x = 31.50 (standard form: y = -1/2x + 7)
if you graph the system, lines intersect at (2, 6)
Answer:
D
Step-by-step explanation:
if you look at the chart. it goes up five and has a width of 2. multiply 5 x 2 = you get 10
