Plugging this into wolfram alpha gives me:
18/5
The correct answer is A.
The independent variable is time and the dependent variable is distance; this means the slope tells us how far she goes per minute. Since the slope is negative and we are referring to her distance from her house, this means the distance from her house is decreasing, which means she is getting closer to her house.
You need to solve for x
12x2 - 13x + 3 = 0
24 - 13x + 3 = 0
27 - 13x = 0
27 = 13x
27/13 = x
your answer will be 27 over 13
Answer:
A) x = 12
B) = 154
Step-by-step explanation:
RVT is a straight line so it must have an angle of 180º. If we take the 26º from ST we know that RS is equal to 154º
So we should set the equation (15x-26) = 154
We should always keep the equation balanced so to do this we're going to add 26 to both sides to get x by itself.
Your equation should now look like this. 15x = 180
Then divide both sides by 15 to get x = 12
We know that UR is also 26º because RS is 154º That makes RU congruent to ST and RS congruent to UT
