Answer:
-x + y = 0 or x - y = 0
Step-by-step explanation:
The line passes through points (0, 0) and (4,4), then its slope is:
m = (4 - 0)/(4 - 0) = 1
Given that the line passes through (0, 0), its y-intercept is
b = 0
Using slope and y-intercept form:
y = mx + b
y = x
The standard form of a line is:
Ax + By = C
So, we have to put all variables on the left side, as follows:
-x + y = 0
Multiplying by (-1) at both sides:
x - y = 0
Answer:
y=25x
where x is hours traveled and y is kilometers traveled
Step-by-step explanation:
2/8 and 4/16 are equivalent to 1/4
Answer:
1. A resposta é a opção C.
2. ( a +b )² = a² + 2ab + b² Verdade
( a - b )² = a² - 2ab + b² Verdade
( a + b ) .( a – b) = a² + b² Falso
( a +b)³ = a³ + 3a²b + 3ab² + b³ Verdade
( a -b)³ = a³ - 3a²b + 3ab² - b³ Verdade
3. a.) m² - 14am + 49a² = ( m - 7a)²
b) m2 – 9n² = m² - (3n)² = (m + 3n)(m - 3n)
c) 30+ 5xy + 12a +2axy = (6 + xy)(5 + 2a)
d) 8a²b + 10ab² = 2ab( 4a + 5b)

The answer is: [D]: "42" .
_______________________________
Explanation:
________________________________________________________
Consider the "1/9" to be close to "1/10" ; (that is; "0.1" ; since "0.1 = 1/10" ) .
Note that a "negative value" multiplied by a "negative value" equals a "positive value".
Round the "14.1" to "14" ; and the "2.9" to "3" ;
_______________________________________
-14.1 * -2.9 ≈ 14* 3 = 42 .
