Answer:

ok so i am going to give you a litle saying to help you remember the way it goes ok. this problem is in slope-intercept form

"y=mx+b,,b is my y-intercept you'll see,m is my slope which is rise over run"

so if -4 is your slope it will go where the m is in the formula y=mx+b so it would now be y=-4x+b and then the b is your y-intercept so 3 would go where the b is in the formula now now since we plugged in all the parts.

the answer is y=-4x+3

Damm [24]

4 feet 8 inches
______________________________________________________________

First find how many inches are in 4 feet + 8 inches. There are 12 inches in 1 foot. Multiply 4 x 12 = 48. Add 8 to 48 = 56. Laney's height in inches is 56 inches.

Today Robbie is carrying his history textbook and his lunch in his backpack. If the history textbook weighs 2 5/6 pounds and his

Brut [27]

Weight in Robbie backpack is $\frac{27}{6}$ pounds or 4.5 pounds

Solution:

Given that Today Robbie is carrying his history textbook and his lunch in his backpack.

To find: weight in Robbie's backpack

From given,

Weight of history book = $2\frac{5}{6}$ pounds

Weight of lunch = $1\frac{2}{3}$ pounds

weight in Robbie's backpack = Weight of history book + Weight of lunch

$\rightarrow 2\frac{5}{6} + 1\frac{2}{3}$

Convert the mixed fractions

$\rightarrow \frac{6 \times 2 + 5}{6} + \frac{3 \times 1 + 2}{3}\\\\\rightarrow \frac{17}{6} + \frac{5}{3}\\\\\rightarrow \frac{17+10}{6}\\\\\rightarrow \frac{27}{6}$

Thus weight in Robbie backpack is $\frac{27}{6}$ pounds or 4.5 pounds
