Answer:
1 zero: Answer C
Step-by-step explanation:
Keep in mind that the polynomial value is zero at any root. Therefore each point that is a root must lie precisely on the x-axis (where y = 0). In the graph given there is only one such point (Answer C)
To find the area of the shaded part we have to subtract the rectangle area from the triangle area :






And we're done

Answer:
x = -1
Step-by-step explanation:
The equation is -2x + 3 = 2x +7
Group the terms together. Don't forget to change the sign
-2x -2x = 7-3
-4x = 4
Divide both sides by 4
-x = 1
Flip it over
x = -1
Distribute 1/4 to all terms within the parenthesis
9 - 5 = 4
1/4(16x + 60) = (16x + 60)/4 = 4x + 15
4 = 4x + 15
Isolate the x. Note the equal sign. What you do to one side, you do to the other.
Subtract 15 from both sides
4 = 4x + 15
4 (-15) = 4x + 15 (-15)
4 - 15 = 4x
-11 = 4x
Isolate the x. Divide 4 from both sides
(-11)/4 = (4x)/4
x = -11/4
hope this helps
