To find a y-intercept, you set x=0 and solve for y.
y = 16(0) + 41
y = 41
PS
If the equation is in slope-intercept form like this, the y-intercept is always the number at the end, the "b" from y=mx+b.
Answer:
60
Step-by-step explanation:
Because the diameter of this circle is 20 and the formula for the circumference (perimeter) of a circle is pi * the diameter, or πd, which, if π is 3, can be computed as 60.
A takeaway from this problem is that you should memorize basic equations like the circumference/area of a circle.
The vertical lines are absolute values, the number in between them, if negative turns positive.
There's no options but a coupon is a way of getting discounts on items that you buy. Unlike gift cards they are not free money but you do pay less for some tings, usually with purchase of more or another item.
By looking at the formula you can see that the quadratic part is 0 if you fill in x=3 (you know, 3-3 = 0). The outcome of the formula then becomes y= 0+5.
That gives us point (3,5) as the top of the parabola. So there you go, answer A.
