Answer:
D hope this helps
Step-by-step explanation:
-y •2=-2
-2+2=0
4x+x=5x
6+3=9
5x=9
9 divided by 5
x=1.9
So there for I think the answer is 2 it’s closest to 1.9
£66 because 60/10=6 60+6= £66
Answer:
No real roots
Step-by-step explanation:
Given
7x² + 5x + 1 = 0 ← in standard form
with a = 7, b = 5, c = 1
To determine the nature of the roots use the discriminant
Δ = b² - 4ac
• If b² - 4ac > 0 then roots are real and distinct
• If b² - 4ac = 0 then roots are real and equal
• If b² - 4ac < 0 then the roots are not real
Here
b² - 4ac = 5² - (4 × 7 × 1) = 25 - 28 = - 3
Thus the 2 roots are not real
Answer:
-4 ≤ f (
) ≤ 4
Step-by-step explanation:
The range of a function is the allowed y-values of the function.
We can simply look at the periodic function below and see that the y-value ranges from a negative 4 to a positive 4. It oscillates betwen -4 and 4. That is the range.
We can say -4 ≤ f (
) ≤ 4
Last answer choice is right.
