Answer: B) y=2x+1
Step-by-step explanation:
These are in slope intercept form which is y=mx+b
where m is the slope and b is the value of the y intercept
Since the y-intercept is 1 on this line that leaves us with A, B, and C
Using the communitive property on the equation in C we can make the equation go from y=1-2x to y=-2x+1
This is the same answer as A and since there can't be two of the same answer leaves B as the only possible answer.
Answer:
78.5 units
Step-by-step explanation:
To find the area of a circle the formula is πr"2"
First we have to find the diameter the find the radius. We already know that the circumference is 31.4 what we have to do now is work backwards. ( 31.4 / 3.14=10) If the diameter of a circle is 10 the radius is 5. now we just have to follow πr"2" to find the area of a circle. (5"2"= 25 x 3.14= 78.5 units)
.6 *.6 (because each one is .4 off)= .36
.36 = 36% of the retail price
The value of a is 26 degrees
