Answer:
A. moving forward for 10m at a steady pace of 2m/s
B. moving backwards 8m at a steady pace of 2.67m/s
C. staying in the same spot for 4 seconds
D. moving 9m at a steady pace of 4.5m/s
E. moving 4.5m with an <u><em>average</em></u><em> </em>pace of 1.5m/s
The correct answer is: " 10 " .

→ " f(-3) = 10 " .

Explanation:
___________________________________________
Given:
___________________________________________
f(x) = 7 − x ; if: x ≤ -3 ;
f(x) = x + 4 ; if: x > -3 ;
_________________________________________
Find: " f(-3) " :
_________________________________________
Note: " f(x) = f(-3) " ; → " x = - 3 " ;
Since " x = - =3 " ; → x is NOT greater than "-3" ;
→ So; " f(x) does NOT equal " x + 4" ;
_________________________________________
Consider our other option given:
We have "x = -3 " .
We our given: If " x ≤ -3 " ; {that is; if "x" is less than or equal to "-3" };
→ then: " f(x) = 7 − x " .
______________________________________________
Since: " x = - 3 " ;
→ then " x ≤ -3 " ; and:
→ f(x) = 7 − x ;
THEN:
→ f(-3) = 7 − (-3) ; → Note: Plug in "-3" for the value(s) of "x" in the equation;
and solve:
→ = 7 + 3 ;
= 10 .
___________________________________________________→ f(-3) = 10 .
_____________________________________The answer is: " 10 " .

It is B
Step-by-step explanation:
Answer:
Step-by-step explanation:
10+100=1000
20+100=2000
The size of the largest square is 36m². To find for the measures of the squares, use the common factors of 42 and 60. Among the common factors, choose the greatest.
Find the factors of 42 using the listing method.
42 - 1, 2, 3, 6, 7, 14, 21, 42
Find the factors of 60 using the listing method also.
60 - 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
Identify the common factors of 42 and 60.
42 - 1, 2, 3, 6, 7, 14, 21, 42
60 - 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
Common Factors: 1, 2, 3, 6
Therefore, the size of the largest square is 36m² since 6m x 6m is equals to 36m².
