Answer:
from the question, the expression for the total amount of money from tickets sales will be T=4 × the number of children
The slope is this and that
Typically, the equation of a circle is given like this: (x-h)^2 + (y-k)^2 = r^2, where r is the radius of the circle and the point (h,k) is the center. To find the value k, you need to put the first equation you have into this form. Standard form requires that you only have the1 y variable, as seen in the parentheses, so you first need to complete the square.
x^2 + y^2 - 2y = 11
x^2 + y^2 - 2y +1 = 11 + 1
x^2 + (y - 1)^2 = 12
And that puts the equation in standard form. k = 1.
Answer: is C
Step-by-step explanation:
because > means open circle but it closed so its not A)
and its not D because the sign is opposite and
b and c both have the correct sign which shows which
direction the line is moving
so the answer is C because it has 4x and ends at 22 these statement are correct
Hope you understand :)
Answer: D. (0,10)
Why:
Your given equation is 5x+2y=20, so in order to find the y-intercept, we must put it in slope-intercept form, a.k.a. y=max+b.
To do this, subtract 5x from both sides. This will then give you 2y=-5x+20.
And to fully simply, divide both sides by 2. Finally, you get y=(-5/2)x+10. And since we know b in slope-intercept form is the y-intercept, and 10 is b in our final function/equation. We get the answer of y-intercept=(0,10)
