up to = less than or equal  to

at least = greater than or equal to


The answer is correct

the max weight shall be 80

mass of small box = 5 lb. ( and there are x number of boxes )

Mass of big box = 12 lb. ( and there are y number of boxes )

adding them up shall be less than or equal to 80 ( as the shelf can withstand up to 80 lbs. )


And the minimum number of boxes shall be equal to 4

If we take the x as the number of boxes, then x would be greater than or equal to 4

Hope my answer helps!

Write the equation of the line in slope-intercept form that goes through the points (4, -2) and (8, -9)
LenaWriter [7]

Answer:

y = 17/6 x - 40/3

Step-by-step explanation:

Slope-intercept form: y = mx + b

First, let's find the slope:

slope formula: (y2-y1) divded by (x2-x1)

(4, -2) and (8, -9)

(-9 - 8) divded by (-2 - 4) = 17/6

We found m, now we have to find b.

The new equation: y = 17/6 x + b

Insert any of the two points, in this case, I'll insert (4, -2)

-2 = 17/6 (4) + b

-2 = 68/6 + b

b = -2 - 68/6

b = -40/3

Overall equation: y = 17/6 x - 40/3

A rectangular swimming pool measures 50 meters in length and 25 meters in width. Using a scale of 1 centimeter represents 5 mete
mrs_skeptik [129]

Answer:

Width is 5 cm

Step-by-step explanation:

Since we know that the width is 25 meters, and the scale we are using is 5 meters = 1 cm, we can divide 25 by 5 to find the scaled measurement.

25/5 = 5cm

I hope this helps!

R varies directly as s. Find r when s=10 and k=4
nadezda [96]

Step-by-step explanation:

Since, r varies directly as s

\therefore \: r \:  \:  \alpha \:  \: s \\  \therefore \: r  = k s..(1) \:  \\ (k =  \: constant \: of \: proportionality ) \\ plug \: s = 10 \: and \: k = 4 \:  in \: equation \: (1) \\ r = 4 \times 10 \\ \huge \red{ \boxed{ \therefore \: r  =40}}
