3x - 4y = -12 Find the x and y intercepts

ixgj

Y=3 and X=-4

Step-by-step explanation:

How you find the Intercepts is by placing a zero is the X place when you trying to find the Y intercept and the other way around to find X.

3(0) - 4y=-12, -4y=-12, y=3

3x - 4(0)=-12, 3x=-12, X=-4

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
