A 5 pound bag of dog food costs $8.65 . what is the unit price?

inessss [21]

So it would be $8.65/ 5lbs. And divide the top and the bottom by 5 and you get $1.73/ 1 lbs. I hope this helps!

Can someone help with my homework?

USPshnik [31]

Step-by-step explanation:

To divide by a fraction, multiply by its reciprocal.

1) (m² / 9) / (n² / m)

(m² / 9) × (m / n²)

m³ / (9n²)

2) (4 / y) / (2 / (yx))

(4 / y) × (yx / 2)

3) (x² / y) / (1 / y)

(x² / y) × (y / 1)

x²

4) (3 / b) / (9 / a²)

(3 / b) × (a² / 9)

a² / (3b)

5) (x² / 16) / (16 / y²)

(x² / 16) × (y² / 16)

x²y² / 256

Use slope-intercept form, y = mx + b, to find the value for the y-intercept (b) of a line that has a slope of 6 and passes throu

stiks02 [169]

Answer:

-23, $y=6x-23$

Step-by-step explanation:

We need slope intercept form but do not have the needed information. We will gather this information by using point slope form. The point-slope formula is $y -y_{1} =m(x -x_{1})$ where we substitute a point (x,y) for $(x_{1},y_{1})$ .

We have slope represented as m=6 and (3, -5). We input m and $x_{1} =3\\y_{1}=-5$ .

$y-(-5)=6(x-3)\\y+5=6(x-3)$

We now simplify the parenthesis and solve for y to have slope intercept form.

$y+5=6(x-3)\\y+5=6x-18\\y+5-5=6x-18-5\\y=6x-23$

The y-intercept is b of slope intercept form y=mx+b. Here b=-23.
