Answer:

x > 22

Step-by-step explanation:

Deena has already taken 126 calls

She takes 7 calls per hour ( think slope)

y = mx+b

y = 7x+126

She needs to take at least 280 calls. So what she does must be greater than 280

280 <7x+126

We need to isolate x. The first step is to subtract 126 from each side

280-126 < 7x + 126 -126

154 < 7x

Next, we divide by 7 on each side

154/7 < 7x/7

22 < x

Answer:

Step-by-step explanation:

$10a-25+5b\\\\-2(-5a-25+5b)=(-2)(-5a)+(-2)(-25)+(-2)(5b)\\=10a+50-10b\qquad NOT\\\\(2a-5+b)(5)=(2a)(5)+(-5)(5)+(b)(5)=10a-25+5b\qquad YES\\\\10(a-2.5+0.5b)=(10)(a)+(10)(-2.5)+(10)(0.5b)\\=10a-25+5b\qquad YES\\\\(-2a+5-b)(-5)=(-2a)(-5)+(5)(-5)+(-b)(-5)\\=10a-25+5b\qquad YES\\\\-10(-a-2.5-0.5b)=(-10)(-a)+(-10)(-2.5)+(-10)(-0.5b)\\=10a+25+5b\qquad NOT$
