V=u+at
u= 2
a= -5
t=1/2
what is the value of v

Answers

at= -5(1/2)
at= -2.5
v= u + at
v= 2 + (-2.5)
v= -0.5

v=-8 if u equals 2 and a is -5 and t is 1/2 its 2 plus -5 divided by one half or 0.5. you first divide and get -10 plus 2 equals -8

A music school charges a registration fee in addition to a fee per lesson. Music lessons last 0.5 hour. The equation y = 40x + 30 represents the total cost y of x lessons. Find and interpret the slope and y-intercept of the line that represents this situation. Then find four points on the line.

Answers

y=mx+b   M is the slope.Therefore, 40 is slope.

To find Y intercept, you substitute X for 0
So it becomes, y=40(0)+30
Solve it,  y=0+30
y=30
If Y=30 x=0
Y intercept is (0,30)
                       x   y
To find four points, you use the slope. 

Final answer:

The slope of the line in the provided equation represents the cost of each music lesson, while the y-intercept represents the registration fee. These two components are used to calculate the total cost of taking 'x' number of music lessons. Examples of four points on this line include: (0,30), (1,70), (2,110) and (3,150).

Explanation:

In the equation y = 40x + 30, 'y' represents the total cost of music lessons, 'x' represents the number of lessons, 40 is the slope, and 30 is the y-intercept.

The slope, 40, means that each music lesson costs $40. This is a constant rate and doesn't change no matter how many lessons a student takes.

The y-intercept, 30, represents the registration fee that is charged in addition to the cost per lesson. This is a one-time fee that's added to the total cost of the lessons.

For example, four points on the line could be (0,30) when no classes are taken, (1,70) for one class, (2,110) for two classes, and (3,150) for three classes.

If one quadrant equals 90 degrees then 25m+22  plus 9m equals 90 degrees solve the equation for x  first combine like terms then subtract 22 from 90. (25m+22) + (9m)= 90    34m+22=90      34m=68 Divide 68 by 34 and m=2  You can also plug 2 back into both equations and add the results. ( to equal 90).  Angle HLG is 18
