Answer:
(2,8)
Step-by-step explanation:
When you reflect over the y-axis, you change the x to the opposite sign
y reflection → (-x,y)
Answer: x = 20
Step-by-step explanation:
So the figures are the same, except the bigger one is bigger. It's equally bigger on all sides, so basically 6 * y = 15 to find what it is enlarged by. Then multiple 8 by y to find the missing length.
6*y = 15
/6
y = 2.5
8 * 2.5 = 20
We can also check this by:
4 * 2.5 = 10
6 * 2.5 = 15
8 * 2.5 = 20
Answer:
Step-by-step explanation:
a. 2x + 36
2. 6a + 15b
3. 35x + 15y
4. 3p + 2q
5. 3a + 8
Hmm, there are 5 letters
if you cannot repeat the letters
hmm, let's find how many for 4 letters
there are 4! or 4*3*2*1=24
that's how many ways there are to arrange a,b,c, d
now we can multiply it by 4 because there are 4 choices for the last place (e is not included0
24*4=56
answer is 56 different arrangements
