Hello :
<span>Y=x²-2x-19 ...(1)
y+4x=5.....(2)
by (2) : y = 5-4x ....(*)
subsct in (1) : 5-4x</span>=x²-2x-19
x²+2x-24 =0
<span>Δ = 2²-4(1)(-24) = 100=10²
x1 = (-2-10)/2 =-6
x2= (-2+10)/2=4
if : x =-6 by(*) : y= 5-4(-6)=29
if x= 4 y = 5-4(4)=-11
</span><span>solution set system of equation is (-6,29) and (4,-11)______.</span>
60 is 40% of total trees.
total trees = 60 * 100/40 = 150
Answer is D.
Answer:
60^1/2 = 60^0.5 = sqrt 60 = 7.75
good luck :))) <3
Answer:
<h2>The answer is B </h2>
Step-by-step explanation:
The answer is B because
<u>9 </u>new light bulbs + <u>6</u> used light bulbs = <u>15 total</u> bulbs
Meredith <u>selected 2 light bulds</u>
So there's a probability of <u><em>(2/15)</em></u> that Meredith will select a new light bulb and then a used light bulb
