We are asked to determine the opening of the graph of the given equation y² + 16y - 4x + 4= 0. To answer this problem, we need to transform the equation into the standard form where all variable y and variable x are in opposite side such as shown below:
y² + 16y - 4x + 4 = 0
y² + 16y = 4x - 4
y² + 16y + 64 = 4x - 4 +64
(y + 8)² = 4x + 60
Then, the graph opens to the right.
Answer:
2 doll dresses
Step-by-step explanation:
Kathy has 3/4 of a yard of fabric and she needs 3/10 for each doll. To determine the amount of doll dresses she can make we must divide the number of yard by the amount she needs per doll
She can make 2 doll dresses but needs more to complete the 3rd dress.
X=91 and x=8 is the answer
Answer:
x = - 4
Step-by-step explanation:
y = - 8 is the equation of a horizontal line parallel to the x- axis.
A perpendicular line must then be a vertical line parallel to the y- axis.
The equation of a vertical line is x = c
where c is the value of the x- coordinates it passes through.
The line passes through (- 4, - 2) with x- coordinate - 4, thus
x = - 4 ← equation of perpendicular line
B = A over 3 so put the three under the a and -c . a =3 (B+C) divide both sides by 3. A over 3 a equals B plus c subtract C from both sides. B = A over 3 - C I hope this helps so B = (A/3) - C remember divide both sides by 3 subtract C from both sides
