The graph below shows the solution to a system of inequalities: Solid line joining ordered pairs 0, 3.75 and 15, 0. Shade the po

algol [13]

(0,3.75)(15,0)
slope(m) = (0 - 3.75) / (15 - 0) = -3.75/15 = - 0.25 or -1/4

y = mx + b
slope(m) = -1/4
(15,0)...x = 15 and y = 0
now we sub
0 = -1/4(15) + b
0 = -15/4 + b
15/4 = b

y = -1/4x + 15/4
1/4x + y = 15/4....multiply by 4
x + 4y = 15.....and since it is a solid line, it contains an equal sign...and since it is shaded above the line, it is greater.
so ur inequality is : x + 4y > = 15 (thats greater then or equal)

Triangle JKL is graphed on the coordinate plane below. On a coordinate plane, triangle J K L has points (1, 2), (4, 2), (3, 5).

lianna [129]

Given:

The coordinates of the triangle JKL are (1,2),(4,2) and (3,5)

We need to determine the coordinates of the triangle J'K'L' rotated 360° clockwise with the origin.

Coordinates of the triangle J'K'L':

The rule to rotate the triangle 360° clockwise with the origin is given by

$(x,y)\implies (x,y)$

The coordinates of the point J' is given by

$(1,2)\implies (1,2)$

The coordinates of the point K' is given by

$(4,2) \implies (4,2)$

The coordinates of the point L' is given by

$(3,5)\implies (3,5)$

Therefore, the coordinates of the triangle J'K'L' are (1,2), (4,2) and (3,5)

Hence, Option D is the correct answer.

Answer:

D. 8 units

Step-by-step explanation:

I chose that answer because -4 is 4 units away from 0 then you need to get to 4 so you add 4 more units and 4 + 4 is 8 so that means it's 8 units away
