Answer:
B) (x,y) -> (-x,y)
Step-by-step explanation:
By reflecting across the y axis, all y values stay the same, therefore no matter what happens to the x, the second half will be y -> y
Because of the reflection across the y axis, you are simply taking all x values and multiplying by -1 to get x -> -x.
Thus, (x,y) -> (-x,y)
B is the answer
p=j+7/100*j=j+0,07j=1,07 j
Total length of all ribbons = 12 * 3 = 36 inch
Then, number of ribbons = 36/4 = 9
In short, Your Answer would be: 9 sections
Hope this helps!
So, you know that any number with 100 as the denominator will be a fraction. All you have to do is change the 10 you have now to 100. To do that, you have to multiply BOTH numerator and denominator (top and bottom) by 10. That results in 70/100, which is equal to 70%.
The equivalent percent for 7/10 is 70%.
