First find the determinant, Δ = b^2 - 4ac
<span>a = 1, b = 8 , c = -2 </span>
<span>Δ = 8^2 - 4*1*-2 </span>
<span>Δ = 64 + 8 </span>
<span>Δ = 72 > 0 </span>
<span>therefore there are two real roots!</span>
Answer:
The table that has a consistent proportionality between Y and X of 2 is choice 2.
Step-by-step explanation:
Because the proportionality between X and Y is 2, that means for each x value, the corresponding y value will be twice as big. The only option that meets this requirement is choice 2, so that is the correct answer.
Answer:
12dollars
Step-by-step explanation:
so to figure sells tax of 6percent on every dollar you take amount spent say take 20 ×.06 now . 06 is 6percent equals 1.2 so a dollar 20 cents is added to 20 making 21.20 so to find original price you always to opposite of the equation so if sells tax . 72 divide it by .06 and you get 12
Hey there!
Perimeter is the combination of all the sides.
side+side+side+side= P
We know that P, or perimeter, is 14 yards.
And we know that one side is 4 yards.
4 * 2= 8 (we know two sides have to be the same)
14-8= 6
Now we have 6 yards left and two sides. So, we should divide by two.
6/2=3
x=3
I hope this helps!
