ralph and edie each solved the equation (x-7)^2 - 100 = 0. ralph says the correct answer is x= -3. who is correct? how do you know?

Answers

Ralph is correct.
Explanation:
X = -3
(-3-7)^2-100 = 0
You do parentheses first according to PEMDAS so:
-3-7 = -10
(-10)^2-100 = 0
Next, you do exponents
-10^2 or -10 * -10 = 100
Finally, you subtract
100-100 = 0

x=

Answers

Answer:

We can fine x by using the pythagoras formula

a²+b² = c²

Which C is X

And

a= 17

b= 15

So

a² + b² = c²

(17)² + (15)² = c²

289 + 225 = c²

514 = c²

√514 = c

22.67 = c

So basically X is (22.671)

The missing side of the given right angled triangle is 8 units.

In the given right angled triangle, the hypotenuse side is 17 units, base is 15 units and the height is x units.

By using Pythagoras theorem, we get

17²=15²+x²

289=225+x²

x²=289-225

x²=64

x=√64

x=8 units.

Therefore, the missing side of the given right angled triangle is 8 units.

Which type of function is most likely to model these data?
A

O
B
linear function with negative rate of change.
non-linear function that decreases then increases
D
non-linear function that increases then decreases

Answers

Answer:

D

Step-by-step explanation:

I'm going to ponder a guess that the numbers shown, 0, 62, 1, 78, 2 ,etc. are part of a table. Having said that, the answers, when graphed, create a sort of parabola, meaning that the function itself is non-linear. This exterminates option A and B. Now its just a matter of seeing which way it goes, and since 78 is higher than 62, and 85 is higher than 78, it obviously increases, rather than decreases. This makes D our final answer.

All you do is pythagorean theorem. Which is A squared plus B squared equals C squared. Think of each graph as a right triangle.
