6
Step-by-step explanation:
The radius of a circle does not change with direction, it stays constant. This, the radius of the bigger circle is 4, and of the smaller circle is 2. Thus, OP equals 4 + 2 = 6. You're correct! :)
Answer:2.6
Step-by-step explanation:
Use your graphing calculator of you have one and if you don't you can find one online and plug in the equation and find the intersection . If you get 2.5571 round it to the nearest tenth and you should get 2.6
Answer:
y = 1/2x +4
Step-by-step explanation:
You are given the slope (m) of the line and a point, and asked for slope-intercept form:
y = mx +b . . . . . . . line with slope m and y-intercept b
The value of the intercept, b, can be found from the point by rearranging this equation to ...
b = y -mx
b = 1 -1/2(-6) = 4 . . . . using x=-6, y=1
Then the equation of the line with m=1/2 and b=4 is ...
y = 1/2x +4
The equation would be y=32x+550. 32 an hour is represented by 32x since she earned 32 an hour. 550 is the extra amount she is getting paid.
I hope this helps.
