Answer:

(3,-2) not given in the options.

Step-by-step explanation:

The points may be determined by solving the quadratic equation. This can be done through the factorization method with y equated to 0.

It means that

x^2 - x - 6 = 0

x^2 - 3x + 2x - 6 = 0

x(x - 3) +2 (x - 3) = 0

(x - 3)(x + 2) = 0

x = 3 or -2

The answer is (-2, -1), because when substituted in the expression is correct:
-1 < 4 - -2 - 6
-1 < 6 - 6
-1 < 0

I hope this helps!

Find angles EFG pleaseee
Bumek [7]

Answer:

50 degrees.

Step-by-step explanation:

Angle FGE = 180-(7x+18) because angles on a straight line add up to 180 degrees.

Angle EFG = 180-38-(180-(7x+18))=6x-10 (Angles in a triangle add up to 180)

180-38-\left(-7x+162\right)=6x-10

180-38+7x-162=6x-10

7x-20=6x-10

Add 20 to both sides:

7x-20+20=6x-10+20

7x=6x+10

Subtract 6x from both sides:

7x-6x=6x+10-6x

x=10

Angle EFG=6x-10=6(10)-10=60-10=50

What does the Principle of Superposition tell us about relative ages of the strata in the cross-sections you were looking at? Ol
iogann1982 [59]

Answer:

1. The Principle of superposition states that a strata of rock is younger than the one over which it is laid.

2. The intrusion of the younger rock by the principle of cross-cutting relationship

3. The intrusion igneous rock arrived after the rock it is found in had already been in place and is stable.

Step-by-step explanation:

In geology, the Principle of superposition states that, in its originally laid down state, a strata sequence consists of older rocks over which younger rocks are laid. That is, a stratum of rock is younger than the stratum upon which it rests.

The principle of cross cutting relationships in a geologic intrusion occurrence, the feature which intrudes or cut across another feature is always than the feature it cuts across.

The reason is that based on the geologic time frame, the rock 1 which ws cut across by rock 2 was already in the geologic zone in a more steady state than rock , therefore it is older than the cutting rock 2.

Find the slope of the line containing the pair of points.<br> ​(6​,5​) and ​(​0,​0)
GarryVolchara [31]

Answer: 5/6

Step-by-step explanation:

Use slope formula of y2-y1/x2-x1. So here it doesn’t matter which is which so I did (6,5) x1 and y1 and (0,0) x2 and y2

So plugging it in it would be 0-5/0-6 = -5/-6 which simplifies to 5/6
