Answer:
All three are rational numbers.
Step-by-step explanation:
I used Desmos (a graphing calculator online) and the roots were all able to be written with fractions.
Answer:
270
Step-by-step explanation:
Jones turns out 200 relays to Smith's 180. You set up that basic ratio and make a proportion out of it.
S/J = 180/200
Now you make your proportion
S/J = x/300
But the 2 ratios much remain the same.
180/200 = x / 300 Multiply both sides by 300
180*300/200 = x Multiply the numerator together.
54000/200 = x Do the division
270 = x
Smith will have turned out 270 relays.
The expression is undefined when C, x = 9.
The way that this expression can be undefined is if the denominator is 0 (dividing by 0 is undefined). To make the denominator 0, that means that 9 - x =0. That means that x = 9. So, when x = 9, the denominator is zero, meaning that the expression is undefined when C, x = 9.
Answer:
68
Step-by-step explanation:
180-112=68

Hi there!
Here is the step by step solving :
-19 = 5(x + 9)
Distribute the 5 to the entire parentheses
5 × x = 5x
5 × 9 = 45
-19 = 5x + 45
Subtract 45 from each side of the equation
-64 = 5x
Divide each side of the equation by 5
-64/5 = x
So your answer is : A. x = -64/5
There you go! I really hope this helped, if there's aything just let me know! :)
