Answer:
X-int= -2 and -4 Y-int= -8 Vertex= (-3,1)
Step-by-step explanation:
The y-int is the point where the graph goes through the Y-axis
The x-int is the point where the graph goes through the X-axis
The vertex is the point where the graph stops rising( in this case) and starts dropping (in this case). For a parabola that opens upwards the opposite is the vertex.
Answer:
4 + 5i
Step-by-step explanation:
To calculate this you have to combine the like terms until they cannot be combined any further:
7 + 10i + 4 - 10i - (7 - 5i)
11 + 0i - 7 - 5i
7 & 4 are liked terms so add them together + subtract 10i and 10i
4 + 5i <--- Final answer
Hope this helps!
Answer:
7 units down
Step-by-step explanation:
it goes from 0 as intercept to -7
Answer:
Y = -1/2x+4
Step-by-step explanation:
The Y intercept is 4, so that's where the +4 comes in.
The slope is rise over run, so you count how many up you go from a whole number, in this case one, and that goes on top. Then you count how many it goes over, in this case two, and that goes on the bottom. The negative comes from which way the slope is going; down or up.
