Degree is the value of the highest power of the variable, and hence in this case is 8
Answer:
A
Step-by-step explanation:
theare are 5 part from 0 to -1
since, the value from 0 to -1 is -1 then if we break it to 5 part, each part has value of -1/5
so, to be -4/5, -1/5 must be multiplied by 4, so we need to go to the 4th part from 0, so it A
The equation for a parabola with directrix y = –p and focus (0, p)
The distance between vertex and directrix is P
Also the distance between vertex and focus is also P
Focus (0,p) so focus lies on y axis
Directrix line is paralled to focus point
So Directex crosses the x axis .
Hence line of symmetry lies is the y-axis.
The graph is attached below.
Y = -3/8x+ -2/4 the answer
Answer:
x = -1 and x = 4
Step-by-step explanation:
Step 1: Get everything to one side of the equation so it's set equal to zero..
-x² + 4x = x - 4 becomes...
-x² + 3x + 4 = 0 (subtract x and add 4 to both sides)
x² - 3x - 4 = 0 (divide both sides by -1, we want the x² term to be positive)
(x - 4)(x + 1) = 0 (factor)
so
x - 4 = 0, then x = 4
and
x + 1 = 0, then x = -1
