$1.75

If 4 lemons altogether cost $7, you want to divide the price by 4 to find the price for one single lemon.

7/4 = $1.75

Now if you buy 4 lemons that cost $1.75, your total will add up to $7

Convert y = x^2 + 2x - 5 into the form y-k = a( x- h)^2

leva [86]

Answer:

$y+6=(x+1)^{2}$

Step-by-step explanation:

we have

$y=x^{2}+2x-5$

This is the equation of a vertical parabola open upward (because the leading coefficient is positive)

The vertex is a minimum

The equation of a vertical parabola into vertex form is

$y-k=a(x-h)^2$

where

(h,k) is the vertex of the parabola

Convert the equation into vertex form

Move the constant term to the left side

$y+5=x^{2}+2x$

Complete the square

$y+5+1=x^{2}+2x+1$

$y+6=x^{2}+2x+1$

Rewrite as perfect squares

$y+6=(x+1)^{2}$

therefore

$a=1\\h=-1\\k=-6$

The vertex is the point (-1,-6)

Volume of pyramid = 1/3 * height * area of the base

= 1/3 * volume of the cube

= 6 cm^3

4 - 3x = 8 - 4x Plz answer this question

timurjin [86]

Answer:x=4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4−3x=8−4x

4+−3x=8+−4x

−3x+4=−4x+8

Step 2: Add 4x to both sides.

−3x+4+4x=−4x+8+4x

x+4=8

Step 3: Subtract 4 from both sides.

x+4−4=8−4

x=4
