Step-by-step explanation:

– x2 + 4x + 1 = x + 1

-x^2 + 3x = 0

x(-x - 3)

x = 0 or -x - 3 = 0 which gives x = 3.

Answer:

x = 0 or x = 3

Step-by-step explanation:

if f(x) = g(x) then – x2 + 4x + 1 = x + 1

add the like terms

-x^2 +3x = 0

-x (x-3) = 0 then x is either 0 or 3

mr Goodwill [35]

Answer:

2 batches

Step-by-step explanation:

(72 lb)/(34 lb/bat) = 2 2/17 bat

___

72 ÷ 34 = 2 remainder 4.

Mateo can make 2 full batches, and will have 4 pounds of apples remaining.

The fraction 4/34 can be reduced to 2/17. That is the fraction of a batch that Mateo could make with the extra 4 lbs. of apples.

Find the distance between each set of points. Round to the nearest tenth, when necessary. (-3, 2) and (1, -6)

vovangra [49]

Answer:

<h2>The answer is 8.9 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

$d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-3, 2) and (1, -6)

The distance between them is

$d = \sqrt{ ({ - 3 - 1})^{2} + ({2 + 6})^{2} } \\ = \sqrt{ ({ - 4})^{2} + {8}^{2} } \\ = \sqrt{16 + 64} \\ = \sqrt{80} \: \: \: \: \: \: \: \: \: \: \\ = 4 \sqrt{5} \: \: \: \: \: \: \: \: \: \: \\ = 8.9442719...$

We have the final answer as

8.9 units to the nearest tenth
