cause the answer of 63.56 +(-81.47)= -17.91
Answer:
y = (x + 9)² + 9
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
given a parabola in standard form : ax² + bx + c : a ≠ 0
the the x-coordinate of the vertex is
= - 
y = x² + 18x + 90 is in standard form
with a = 1, b= 18 and c = 90
= - 
= - 9
to find the corresponding y-coordinate substitute x = - 9 into the equation
y = (- 9)² + 18(- 9) + 90 = 81 - 162 + 90 = 9
⇒ y = (x + 9)² + 9 ← in vertex form
a) 3 1/4 pounds of apple costs $6.46
b) X pounds of apple costs $1.99X
c) Clare bought 2.59 pounds of apple
Step-by-step explanation:
Cost of apple per pound= $1.99
a) 3 1/4 pounds = 13/4 pound
Cost for 13/4 pounds of apple = 1.99(13/4)
= $6.46
b) cost for X pound = 1.99(X)
=$ 1.99X
c) money spent for apples = $5.17
Cost per pound = $1.99
Total weight of apple bought = 5.17/1.99
= 2.59 pounds of apple
Answer:
x = 27/5
Step-by-step explanation:
Step 1: Write equation
-12 = -5(x - 3)
Step 2: Solve for <em>x</em>
- Distribute -5: -12 = -5x + 15
- Subtract 15 on both sides: -27 = -5x
- Divide both sides by -5: x = 27/5
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
-12 = -5(27/5 - 3)
-12 = -5(12/5)
-12 = -12
