PLEASE HELP, 10 points :-3 MATH 8th grade QUESTION IS The Marcos family consists of 2 adults and 4 children. They spent a total of $40 on circus tickets. Let x represent the cost of an adult ticket, and let y represent the cost of a child’s ticket. Which graph represents the possible costs of the tickets?

Answers

(2y + 4x) - 4x = (40) - 4x
2y = -4x + 40
(2y) / 2 = (-4x + 40) / 2
y = -2x + 20
20 is the y intercept
(-2 / 1) is the slope

B

(Or whichever the one that has a y-intercept of 20 and an x-intercept of 10.)
the answer is B or the 2nd option

Answer:

Angle of depression from C to T measures approximately 20.52^o

Step-by-step explanation:

To start, we use triangle DTA to find the length of the side AT, making use of the tangent function:

tan(23^o)=(AT)/(28\,m) \nAT=tan(23^o)\,* 28\,m\nAT=11.89\,m

Now we need to find the size of the rectangular land diagonal:

diagonal=√(28^2+15^2)=31.76\,m

With this information, we can now find the measure of angle "C" (depression angle from C to T), using the triangle ACT:

tan(C)=(opposite)/(adjacent) \ntan(C)=(11.89)/(31.76)\nC=arctan((11.89)/(31.76))\nC=20.52^o
