Answer:
The vertex form is y = (x + 4)² - 13
The minimum value of the function is -13
Step-by-step explanation:
∵ y = x² + 8x + 3
∵ 8x ÷ 2 = 4x ⇒ (x) × (4)
∴ We need ⇒ x² + 8x + 16 to be completed square
∴ y = (x² + 8x + 16) - 16 + 3 ⇒ we add 16 and subtract 16
∴ y = (x + 4)² - 13 ⇒ vertex form
∵ The vertex form is (x - a)² + b
Where a is the x-coordinate of the minimum point and b is y-coordinate of the minimum point (b is the minimum value of the function)
∴ The minimum value is -13
Answer: 6x +18x - 6= -12
24x - 6 = -12
+6= +6
24x = 6
X= 4
Answer:
answer is the first option
Step-by-step explanation:
double checked all and the first one is the correct one
Answer:
C. no real number solutions
Step-by-step explanation:
Subtract 10 from both sides.
Since the square of a number, x, equals a negative number, -1, the answer cannot be a real number because the square of a real number is always non-negative. Therefore, there is no real number solution to this equation.
Answer: B. no real number solutions
no real number solutions
1.5x + 4 (greater than or equal to) 7
It is greater than or equal to because she wants at least seven cm, which means that the length CAN be 7 cm, and it’s greater than because at least means a minimum of, so 7 cm or longer.
You add four because that’s how much hair she has already and you have 1.5x because that how much she growth per month. Plug in how many months for x and we’ll get a length in that amount of time
