Mrs. Baker paid $2.50 for 5 pounds of bananas. Write an equation relating to the cost to the number of pounds of bananas. How mu

tensa zangetsu [6.8K]

The equation is 2.50÷5=x
2.50÷5=.50
Mrs. Baker paid $2.50 for 5 pounds of bananas
If x=.50 per banana
Then to get the cost of 8 bananas, you would do 8×.50=$4.00
Mrs. Baker paid $4.00 for 8 pounds of bananas
Each banana costs .50 cents per pound

I need help with this one I’m not sure if I got it right

Answer:

144 feet

Step-by-step explanation:

Since this is a quadratic equation, we simply need to find the vertex in order to determine the maximum height!

To solve the equation, follow these steps!:

$0 = 16t^2+96t\\\\\frac{-b}{2a} =x\\\\\frac{-96}{2(-16)}=3=x$

Now we insert x back into the equation...

$= -16(3)^2+96(3)\\ = -16(9)+288\\ =-144+288\\=144$

Answer: (-0.61, 5.85) and (-2.72, 3.04)

Step-by-step explanation:

y = 2x² + 8x + 10

y = -x² - 2x + 5

Use substitution method to get: 2x² + 8x + 10 = -x² - 2x + 5

Move everything to one side and 0 on the other: 3x² + 10x + 5 = 0

Use the quadratic formula to solve for x: $\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}$

$x=\dfrac{-(10)\pm \sqrt{(10)^2-4(3)(5)}}{2(3)}\\\\\\.\ =\dfrac{-10\pm \sqrt{100-60}}{6}\\\\\\.\ =\dfrac{-10\pm \sqrt{40}}{6}\\\\\\.\ =\dfrac{-10\pm 2\sqrt{10}}{6}\\\\\\.\ =\dfrac{-5\pm \sqrt{10}}{3}$
