Answer:
True
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (- 4, - 9), thus
y = a(x + 4)² - 9
To find a substitute the coordinates of the zero (- 7, 0) into the equation.
0 = a(- 7 + 4)² - 9, that is
0 = 9a - 9 ( add 9 to both sides )
9a = 9 ( divide both sides by 9 )
a = 1, thus
y = (x + 4)² - 9 ← expand factor using FOIL
y = x² + 8x + 16 - 9
y = x² + 8x + 7
Answer: y+3 = 4( x + 1)
Step-by-step explanation:
The equation in point slope form is given as :
y -
= m ( x -
) , where m is the slope
slope = 4
point given : (-1,-3)
Using the formula :
y -
= m ( x -
)
and substituting the value , we have
y - (-3) = 4 (x -{-1} )
y+3 = 4( x + 1)

Answer:
61
Step-by-step explanation:
Let's write out what we know:
Noon temp: 54
Over the day, the temperature:
increased 8, decreased 3, increased 14, decreased 2, and decreased 10.
54+8-3+14-2-10 = 61
