Answer:
15 and a half
Step-by-step explanation:
Bud=17
17-(2/3 x 2)=? 2/3=0.67%, 0.67% of 2=1.34
17- 1.34= 15.66
Answer:
B is right. A is 50 km/h B is 55 km/h and C is 45 km/h
Answer:
(53, -17/2)
Step-by-step explanation:
When you have transformatons a * f(b(x-c)) + d there are two steps to transform.
Step 1, multiply x by 1/b and multiply y by a pay attention to posities and negatives.
Step 2 add c (keep in mind if you have -c you add c and if you have +c you subtract) to x and d to y.
In your example the transformation is 1/2 f(-1/3 (x+4)) - 7 so
a = 1/2
b = -1/3
c = 4
d = -7
and the point is initially (-19, -3)
Now lets do the two steps
multiply x by 1/b and multiply y by a pay attention to posities and negatives.
b = -1/3 so 1/3 = -3 and a = 1/2 x = -19 and y = -3 So we do -19 * -3 and -3 * 1/2. This gives us the new point (57, -3/2)
Now step 2 add c (keep in mind if you have -c you add c and if you have +c you subtract) to x and d to y.
Now our point is (57, -3/2) and c = 4 and d = -7 so we do 57-4 and -3/2 - 7
This gets us (53, -17/2)
Let me know if there is anything you don't understand.
Yes, percent is a number.
You have to add all of those fractions up since they are asking for the total weight.
so you do 2 1/2 + 3/8 + 1 1/4 = 4 1/8
