Df/dx=3/2=1.5  so this line has a positive constant rate of change.  y increases by 1.5 for every 1 increase in x.

So B. is the only true statement as y values increase as x values increase.

Jeff's salary is 25% higher than Josh's. By how many percents is Josh's salary less than Jeff's?
Serggg [28]

Answer:

Josh's salary is 20% less than Jeff's.

Step-by-step explanation:

Let

x----> Jeff's salary

y----> Josh's salary

we know that

x=1.25y

Solve for y

y=(1/1.25)x

y=0.8x

therefore

Josh's salary is 80% of Jeff's salary

or

Josh's salary is 20% less than Jeff's.

Suppose two adjacent endpoint of a rotated square are located at (-4, -6) and (5, -1) on the coordinates axes. What is the lengt
kompoz [17]
To find the length of side of square, we have to use distance formula.
Points are (-4,-6) and (5,-1)
Formula for distance between two points.
d= \sqrt{( x_{2}-x_1 )^2+(y _2-y_1)^2 } \\ 
Put \ values \\
d= \sqrt{( 5+4)^2)+(-1+6)^2  } \\ 
d= \sqrt{( 9)^2)+(5)^2 } \\ 
d=\sqrt{106} \\ 
d=10.3 \ units

So length of side of square is 10.3 units.

Answer: 10.3 units

Brenda is making a dessert that takes 3.5 hours to prepare. If she wants to be finished by 1:15, at what time should she start??
dusya [7]
3.5 hours is 3 hours and 30 minutes.
1:15 is 1 hour and 15 minutes. 

The question is asking at what time does she want to start and end up at 1 hour and 15 minutes? SO you add the time it takes for her to make the dessert with the time at which she ends.

TLTR?? 4:45
