Answer:

D 2x+7

Step-by-step explanation:

f(x) = 2x+5

replace x with x+1

f(x+1) = 2(x+1) +5

Distribute the 2

f(x+1) = 2x+2 +5

= 2x+7

Answer:

Option A

Step-by-step explanation:

At Step 2 you subtract 1/2 from both sides of the equation:

1/2r = - 2/7r - 29/7 - 1/2
1/2r = - 2/7r - 58/14 - 7/14
1/2r = - 2/7r - 65/14

Its justification is therefore is:

A) The subtraction property of equality

The "given" information should be considered as true. True False

dalvyx [7]

Unless refuted later in the equation, this statement would be True because they are normally giving you the data to work with to save you the time of finding it yourself.

Helen’s house is located on a rectangular lot that is 1 1/8 miles by 9/10 mile.Estimate the distance around the lot

RUDIKE [14]

Answer:

The distance around the lot is 4.05 miles .

Step-by-step explanation:

Formula

$Perimeter\ of\ rectangle = 2 (Length + Breadth)$

As given

$Helen’s\ house\ is\ located\ on\ a\ rectangular\ lot\ that\ is\ 1 \frac{1}{8}\ miles\ by\ \frac{9}{10}\ mile.$

i.e

$Helen’s\ house\ is\ located\ on\ a\ rectangular\ lot\ that\ is\ \frac{9}{8}\ miles\ by\ \frac{9}{10}\ mile.$

Here

$Length = \frac{9}{8}\ miles$

$Breadth = \frac{9}{10}\ miles$

Put in the formula

$Perimeter\ of\ rectangle = 2(\frac{9}{8}+\frac{9}{10})$

L.C.M of (8,10) = 40

$Perimeter\ of\ rectangle = \frac{2\times (9\times 5+9\times 4)}{40}$

$Perimeter\ of\ rectangle = \frac{2\times (45+36)}{40}$

$Perimeter\ of\ rectangle = \frac{2\times 81}{40}$

$Perimeter\ of\ rectangle = \frac{81}{20}$

Perimeter of rectangle = 4.05 miles

Therefore the distance around the lot is 4.05 miles .
