<h2>Hi ☘</h2>

1-A 2-A 3-B

- 104 \geqslant  - 8b - 8

put -8 near -104

- 104 + 8 \geqslant  - 8b

- 96 \geqslant  - 8b

b will be alone.

\frac{ - 96}{ - 8}   \geqslant   \frac{ - 8b}{ - 8}

b  \geqslant 12

Answer A

3m - 7 >  - 4

3m >  - 4 + 7

3m > 3

\frac{3m}{3}  >  \frac{3}{3}

m > 1

Answer A

İf

m \geqslant 1

The answer would be D

But answer A

- 4x + 4 >  - 16

16 + 4  >  + 4x

20 > 4x

\frac{20}{4}  >  \frac{4x}{4}

x < 5

Answer B

A 17-inch candle is lit and burns at a constant rate of 1.3 inches per hour. Let t represent the number of hours since the candl
pshichka [43]

Answer

Since the lyla deleted it actually for a good reason let me explain. But you dont just delete random answers, you can give a comment. I can report you for doing that.

So since it burns at 1.3 per hour. Notice that since it gets removed per hour. so it would be 1.3t so it multiplies per hour. Then we need to subtract. Thats because it lowers the length of the candle. So we get the original length - 17 and get the function

f(t) = 17-1.3t

fenix001 [56]

Answer:

between 222 and 223 days

Step-by-step explanation:

This relation includes the point (0, 2).

A proportional relation must include the point (0, 0).

This is not proportional, but it may be linear.

Points: (0, 2), (2, 20)

y = mx + b

20 = (20 - 2)/(2 - 0) × 2 + b

20 = 18/2 × 2 + b

b = 2

y = 18x + 2

When 4000 people know, y = 4000.

y = 18x + 2

4000 = 18x + 2

3998 = 18x

x = 3998/18

x = 222.111...

Answer: between 222 and 223 days

Samuel is looking at the floor plan of his house to determine how much carpet he needs to buy for his basement. Based on the flo
DerKrebs [107]

Answer:

B) First, find two areas using (4m x 10m = 40m2) and (8m x 3m = 24m2). Next, add (40m2 + 24m2 = 64m2).

Step-by-step explanation:

Samuel should is looking to find the area of his basement in order to cover it with carpet.

An area is calculated by multiplying two dimensions (so answers A and D are not it).

Best solution is to divide the area into two large rectangles then ADD them together to get the total area.

The only scenario where he could have subtracted something based on his plan is if he would have multiplied the 10m by the 12m then subtracted the area that is not part of his basement (7mx8m).  He would have achieved the same result of course, but by going a different way.
