It helps to memorize the quadratic formula as a song. Try in the tune of pop goes the weasel. The quadratic formula is -b. Plus or minus the square root. Of b squared minus 4ac. All over 2a! Just plug in the numbers and you should get an answer. Let me know if you need more help :)

You haven't shared what you're supposed to do here. Instructions?

If you want to find the roots of 0 = x^2+5x - 6, identify the coefficients of the x terms as follows: a=1, b=5 and c= -6.

-5 plus or minus sqrt( 25-4(1)(-6) )
Then x = -------------------------------------------------
2
-5 plus or minus sqrt(49)
= ------------------------------------
2

Thus, there will be two unequal, real answers. Please finish the math and identify these answers.

To solve this problem, we have to use the area of both gauze or the dimensions on each gauze and compare them. we can see that the sheets are not similar as they have different areas.

<h3>Area of Rectangle</h3>

The area of a rectangle is given as the product between the length and it's width.

Data;

Length = 9in
Area = 45in^2
width = ?
length 2 = 4in
width 2 = 3in

$area = length * width$

In the first gauze, the area is given as 45in^2 and we have value of the length. To find the width of the first gauze can be calculated as

$A = length * width\\width = \frac{area}{length} \\width = \frac{45}{9} \\width = 5in$

We can see that the width are not equal so is their length.

But if we would truly compare them, the accurate way to do that is by their area

The area of the second gauze is given by

$a = 3 * 4 = 12in^2$

From the above calculations, we can see that the sheets are not similar as they have different areas.

On Monday, a localamburger shop said a combined total of 225 hamburgers and cheeseburgers. The number of cheeseburgers sold was

zheka24 [161]

Answer:

h = hamburgers sold

2h - 72 = 578

2h = 650

2 2

h = 325

There were 72 fewer cheeseburgers sold than hamburgers. That means cheeseburgers = 325 - 72

325 - 72 = 253

253 = cheeseburgers

325 = hamburgers

253 + 325 = 578

Hamburgers = 325

Hope this helps :)

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept (0, b)

$1.\ \text{Slope is}\ -2\to m=-2,\ \text{y-intercept is}\ -6\to b=-6\\\\\boxed{y=-2x-6}\\\\2.\ \text{Slope is}\ \dfrac{3}{7}\to m=\dfrac{3}{7},\ \text{y-intercept is}\ -1\to b=-1\\\\\boxed{y=\dfrac{3}{7}x-1}\\\\3.\ m=-8,\ b=11\\\\\boxed{y=-8x+11}\\\\4.\ m=0,\ b=-5\\\\\boxed{y=0x-5\to y=-5}\\\\5.\ m=-11,\ \text{y-intercept is}\ (0,\ 13)\to b=13\\\\\boxed{y=-11x+13}$
