Answer:
Lesser = -
- 7 = -10.317
Greater = + - 7 = -3.683
Step-by-step explanation:
I am assuming you are asking for the lesser x solution and greater x solution.
(x + 7)^2 – 11 = 0
(x + 7)^2 = 11
x+7 = ±
x = ± - 7
Lesser = - - 7 = -10.317
Greater = + - 7 = -3.683
Answer:
30x + 15y
answer is d
Step-by-step explanation:
Answer:
(-1,6) ; (-2,11)
Step-by-step explanation:
y= x^2-2x +3
y= -5x + 1
the best way to proceed is substitute the value of y shows in the second equation in the first equation (general rule: substitute the value shows in the linear equation in the quadratic equation)
-5x + 1 = x^2-2x+3
x^2 +3x + 2 = 0
(x+2)(x+1) = 0
x = -2
x = -1
Solution 1
x = -1
y = 5 + 1 = 6
Solution 2
x = -2
y = 10 + 1 = 11
Answer:
8.55 inches tall
Step-by-step explanation:
equation: h = -0.75t +12. The slope is -0.75 because that's the rate of the candle burning, and the y intercept is 12 because that's how tall it is initially.
Now plug in 4.6 for t you get:
h = -0.75t + 12
h = -0.75(4.6) + 12
h = -3.45 +12
h = 8.55 inches tall
333+456=300+30+3=400+50+6=700+80+9=789
4³=64
5²=25
9³=729
64+25+729=
60+4+20+5+700+20+9=
100+18+700=
818
