ANSWER: x will equal 3 I hope this helps
This is the concept of relative speed; We are required to calculate the speed of the car and the bicycle.
Distance between the car and Bicycle=374 miles
Time they met=5.5 hr
Speed traveled by bicycle=x
Speed traveled by car=x+33.4334
Relative speed=x+(x+33.4334)=(2x+33.4334) mph
Distance=speed*time
374=(2x+33.4334)*5.5
374=11x+183.8837
collecting like term we get:
374-183.8837=11x
11x=190.1163
thus;
x=(190.1163)/(11)
x=17.2833 mph
thus the speed of the bicycle was x=17.2833 mph
The speed of the car was (x+33.4334)=(17.2833+33.4334)=50.7167 mph
The first choice if ()2 means to the power of two if not then it is none of them.
Hey!
-------------------------------------------------
Point Slope Form: y - 7 = -5/2(x + 4)
Slope-intercept Form: y = mx + b
m = slope
b = y-intercept
We can automatically eliminate Option A and B because they are both written in point slope form when the questions asks for slope-intercept form.
We can also eliminate option C because the slope in the equation doesn't match the slope in the equation above.
-------------------------------------------------
Answer:
y = -5/2x - 3

Hope This Helped! Good Luck!
The answer would be D. (3.25 for a burger, and 1.75 for a drink)
