Answer:
1. 50
2. 16.6666666667=16.7
3. 5.55555555556=5.6
Step-by-step explanation:
1. 5/0.1=50
2. 5/0.3=16.6666666667=16.7
3. 5/0.9=5.55555555556=5.6
2x+3y=5
-3x+2y=-14
3( 2x+3y=5)
2 (-3x+2y=-14)
--------------------
13y=-13 ⇒y=-13/13=-1
2( 2x+3y=5)
-3(-3x+2y=-14)
---------------------
13x = 52 ⇒x=52/13=4
Answer: x=4; y=-1
To check:
2x+3y=5
2*4+3*(-1)=8-3=5
-3x+2y=-14
-3*4+2*-1=-12-2=-14

Answer:

Step-by-step explanation:
The left section of the function is a parabola with vertex (-3, 3) and a vertical scale factor of -1. You can tell that -1 is the scale factor because the parabola opens downward and 1 horizontal unit from the vertex, the function is 1 unit vertically different from the vertex. (The vertical difference is the scale factor.)
The right section is an absolute value function with a vertex at (0, -1) and a scale factor of 1/2. You can tell the scale factor is 1/2 because the rise/run of the lines is 1/2.
The left section is defined for x < -2; the right section is defined for x ≥ -2.
The vertex locations show the function translation, which is applied in the usual way:
f(x) translated to (h, k) is <em>f(x -h) +k</em>.
