30 in an online game you are rewarded with 20 points each day you log on and 5 dollars. you are trying to raise 1,420 points. you have 100 points. how many days would it take to raise 1,420 points?

 66

Step-by-step explanation:

20 points per day is the rate, 100 points is the intial amount, and 1420 points is the total.

Use the formula: y = mx + b  

1420 = 20x + 100   plugged the values into the equation

1320 = 20x             subtracted 100 from both sides

   66 = x                 divided both sides by 20

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
