X + 5y = -2 2x + y = 5 The point of intersection of the lines has a y-coordinate of . 1 3 -1

Y =-1

Step-by-step explanation:

There is an easy way to find the answer. Basically you want x + 5y = -2 and then you subtract that from 2x + y = 5. What can you do to one of these equations so that when you add them together they will get rid of the x so you just have the y period so the way I did it was double the 2x plus 5y period so now we have 2X plus 10y equals -4. Subtract that from 2x plus y equals 5. The answer is -9y = 9 so y = -1

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
