J/-2+7 = -12
j/5 = -12
j/5 • 5 = -12 • 5
j = -60
Answer:
D) y = 4x + 2
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given ( 0, 2) ( -1 , -2 )
Given in equalities y = 4x + 2
put point (0,2) in equation y = 4x +2
2 = 4(0) +2
2 = 2
Therefore satisfies the point (0,2) equation y = 4x +2
put point (-1,-2) in equation y = 4x +2
-2 = 4(-1)+2
-2 = -2
Therefore satisfies the point (-1,-2) equation y = 4x +2
Answer: 16
Step-by-step explanation:
Total number of laptops ordered= 650
Number of laptops tested= 40
Number of laptops that takes more than 30 seconds to start up= 1
To get the number of laptops that will take 30 seconds to start in the whole shipment goes thus:
Let the number of laptops that will take more than 30 seconds be represented by y.
1 : 40 = y : 650
1/40 = y/650
Cross multiply
40y = 650
y= 650/40
y= 16.25 which approximately gives 16.
There are expected to be 26 laptops that takes more than 30 seconds to start.
