7 0

Answer:

12

Step-by-step explanation:

The number 144 can be factorized as = 2*2*2*2*3*3= (4^2)* (3^2)

Therefore, sqrt(144)= sqrt((4^2)* (3^2))= sqrt{(4*3)^2= sqrt{12^2}=12

Graphing/Slopes (Easy points!!) (ASAP) (URGENT) (Please check my other questions)<br><br>​
spin [16.1K]

Answer:

The statement is incorrect because an inverse relationship between y and x would imply that the graph would be a downward curved graph whose slope changes rather than linear which has constant slope  (see image).

Best to express this situation as:
There is a linear relationship between y and x with a negative constant slope. The keyword here is constant since the slope is the same in a linear relationship

Step-by-step explanation:

An inverse relationship exists between y and x when y is proportional to the reciprocal of y

This would be expressed in the form y ∝ \frac{1}{x}

As x decreases , y increases or vice-versa. It is often expressed in equation form as y=\frac{k}{x}  or y = kx^{-1}   where k is a constant and  whose graph is curved in nature. The slope is changing for the range of x values not constant as would be the case for a linear graph

All we can say about the data is that there is a linear relationship between y and x  with a negative constant slope

Given that QT is and altitude of triangle QRS and that m
iris [78.8K]

Hello from MrBillDoesMath!

Answer:

15

Discussion:

Given: measure angle STQ = 7x + 55.  But, as shown, STQ is a right angle so

7x + 55 = 90          => subtract 55 from each side

7x = 90 -55 = 35   => divide each side by 7

x = 35/7 = 5

Since RS = (x+1)    + (2x-1)  where x = 5.

     RS = (5 + 1) + (2*5 -1)

           = 6         + 9

           = 15

I don't know what choice the answer is as your diagram only shows Choice A

Thank you,

MrB
