The correct answer is 40 which will be letter c
Answer:
Proportional
Step-by-step explanation:
Answer:
i think the point is (2, -5)
Step-by-step explanation:
m = slope
y - y1 = m(x - x1)
replace:
y - (-5) = 3(x - 2)
simplify:
y + 5 = 3(x-2)
point:
y1, x1
replace:
-5, 2
X² + 18x + 79 = 0
x = <u>-(18) +/- √((18)² - 4(1)(79))</u>
2(1)
x = <u>-18 +/- √(324 - 316)</u>
2
x = <u>-18 +/- √(8)
</u> 2<u>
</u>x = <u>-18 +/- 2√(2)
</u> 2<u>
<em /></u><em />x = -9 <u>+</u> √(2)
x = -9 + √(2) x = -9 - √(2)
