Answer: B
Step-by-step explanation:
Solution:
<u>It should be noted:</u>
- If the starting point of the inequality is half shaded, the sign will be < or >.
- If the starting point of the inequality is fully shaded, the sign will be ≤ or ≥.
<u>We can tell that:</u>
- The inequality will either have an < or > sign.
- The blue line tells us that the value of x must be greater than -1.
This clearly tells us that the inequality is x > -1
<u>In conclusion:</u>
Option C is correct.
Answer:
y = 7
Step-by-step explanation:
calculate the slope m using the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 5, 10) and (x₂, y₂ ) = (3, y)
m = =
For this to equal -
since the denominators are equal, equate the numerators
y - 10 = - 3 ( add 10 to both sides )
y = 7
(x+2)(x+6)=0
x^2 +2x+6x+12=0
Answer: x^2+8x+12=0
