For 2, 3, 10, 11, 12, "intercept form" works nicely.
.. x/(x-intercept) +y/(y-intercept) = 1

2) x/4 +y/4 = 1 . . . . . an equation
.. x + y = 4 . . . . . . . . the equation in standard form

3) x/-3 +y/1 = 1 . . . . an equation
.. x -3y = -3 . . . . . . . the equation in standard form

10) x/4 +y/2 = 1
.. x +2y = 4 . . . . . . . in standard form

11) x/-3 +y/5 = 1
.. 5x -3y = -15 . . . . . in standard form

12) x/-10 +y/16 = 1
.. 8x -5y = -80 . . . . . in standard form


For the rest, the 2-point form of the equation of a line will work.
For points (x1, y1) and (x2, y2), the line through them can be written as
.. y = (y2 -y1)/(x2 -x1)*(x -x1) +y1

1) y = (1 -(-3))/(1 -0)*(x -0) +(-3)
.. y = 4x -3

Jeff reads 5/7 of a book in 4 hours. At this rate, how much did he read in 1 hour? Please answer this correctly. Don't put a lin
leonid [27]

Answer:

Jeff read 5/28 of a book in 1 hour.

Step-by-step explanation:

The rate given is 5/7 of a book read in 4 hours.

If the questions asks how much he read in 1 hour, it means the answer needed is a unit rate.

A unit rate is a rate per unit. In this case, a rate per hour.

Let’s find how much Jeff read in 1 hour:

5/7 in 4 hours is the rate given so:

5/7 ÷ 4

= 5/7 x 1/4

= 5/28 (already simplified/final answer)

SO, Jeff read 5/28 of the book in 1 hour.

nirvana33 [79]

Answer:

1152

Step-by-step explanation:

4 boys and 4 girls be arranged in a row such that no two boys and no two girls are next to each other.

Two boys and two girls are not next to each other. so one boy and one girl are next to each other in two ways.

BGBGBGBG, GBGBGBGB

4 boys are arranged in 4! ways and 4 girls are arranged in 4! ways

So number of ways = 2 \cdot 4! \cdot 4!=2 \cdot 24 \cdot 24=1152
