Inequality / Linear Systems Help - 30 points!
Sholpan [36]

They did not include the constraint for y ≤x+3 on the graph.

See attached picture with added constraint.

Using the 4 points that are given as the solution on the graph, replace t he x and Y in the original equation to solve and see which is the greater value.

Point (0,3) P = -0 +3(3) = 0+9 = 9

Point (1,4) P = -1 + 3(4) = -1 +12 = 11

Point (0,0) P = -0 + 3(0) = 0 + 0 = 0

Point (3,0) P = -3 + 3(0) = -3 + 0 = -3

The correct solution to maximize P is (1,4)

14. Trick question, ignore the side.


Call the angle b.


34 + b + b = 180


2b = 146


b = 73


choice b


15. That's intersecting chords so the product of the segment lengths are equal:


5(22)=10 x


x = 5(22)/10 = 11


choice a


16. Intersecting tangent and secant;


x^2 = 5(19)


x = \sqrt{95} \approx 9.75


Choice a

The perimeter of a square is given as 8x+20. Write two different expressions for the perimeter. Use factoring to write one of th
sveticcg [70]

Answer:

P = 4(2x + 5)

P = (2x + 5)+(2x + 5)+(2x + 5)+(2x + 5)

Step-by-step explanation:

Given that:

Perimeter of square = 4 * s

Where s = side length

If perimeter, P = 8x + 20

Then,

4s = 8x + 20

Divide both sides by 4

4s / 4 = (8x + 20) / 4

s = 2x + 5

P = 4s

P = 4(2x + 5)

Or

P = 2x + 5 in 4 places

P = (2x + 5)+(2x + 5)+(2x + 5)+(2x + 5)
