Answer:

Step-by-step explanation:

This is a narrower-than-normal absolute value graph, which is a v-shaped graph. It's pointy part, the vertex, lies at (2, -3) and it opens upwards without bounds along both the positive and negative x axes. Therefore, as x approaches negative infinity, f(x) or y (same thing) approaches positive infinity. As x approaches positive infinity, f(x) approaches positive infinity.

Answer:

x = -2 , y = 4

Step-by-step explanation:

given:

5x + 2y = -2 *4

4x + 3y = 4 *5

Solving simultaneously,

20x + 8y = -8 ....eq 1

(-) 20x +15y = 20 ...eq 2

.............................................

-7y = -28

y = -28 / -7

y = 4

if y = 4

using equation 2,

20x +15(4) = 20

20x = -40

x = -2
