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
X-intercept = -3
y- intercept = -6
Two parallel lines A and B are crossed by another
line as shown in the attached figure. Angle 2 and 3 are equal, because they are
opposite angles, while angle 3 and 7 are also equal, because they are
corresponding angles, thus it is deduced that
angle 2 = angle 3
angle 3 = angle 7
So angle 2 = angle 7

Down 5, right 2
If it's within the parentheses with the x, then it moves left/right. left if +, right if -
If it's outside the parentheses, you go up and down. up if +, down if -
The answer would be 16.
8+8=16
