Answer:
0.5x + 2
Step-by-step explanation:
You switch x and y and then solve for x to find the inverse.
Sonia represented by x. Sophia represented by x+15. x+x+15 = 63
2x + 15 =;63
2x = 48
x =;24. Sonia
x+15 = 39. Sophia
Answer:
(3,5)
Step-by-step explanation:
Here we are asked to find the reflection of Point P(-1,5) along the line represented by x=1
Please refer to the image attached with answer.
We have point P (-1,5) , the line x=1 and the Point R which is the reflection of P across x=1
now we can see that P is 2 units towards left of the line x=1. hence its reflection across x=1 will be 2 units away towards right of line. 2 units away , the x coordinate will be 1+2 = 3
Hence the x coordinate is 3 and y coordinate remains the same. Hence the coordinates of R will be (3,5)
Answer:
The probability of seeing a person wearing black shoes before seeing a person wearing white ones = 60%
Step-by-step explanation:
People watched walking down the street = 100%
People wearing black shoes = 1/2 = 50%
People wearing white shoes = 1/3 = 33.33%
People wearing red shoes = 1/6 = 16.67%
Probability of black shoes to white shoes = percentage of persons wearing black shoes/sum of the percentages of people wearing black and white shoes)
= 50% : 33.33%
= 60% (50%/83.33%)
When expressed in ratio terms, it means that you will see 1.5 (50%/33.33% or 1.5 : 1) persons wearing black shoes before you see a person wearing white shoes.
