Answer:
Step-by-step explanation:
if you modify the parent function to go <u>up and down</u>
for example parent function is y=|x| to go <u>down</u> 3 you do y=|x|-3
if you modify the parent function to go <u>left and right</u>
for example parent function is y=|x| to go <u>right </u>3 you do y=|x-3|
a.goes down 3, and 2 to the right
y=|x-2|-3
b. 3 down and 1 to the left
y=(x+1)²-3
c. 5 up and 2 to the right
d. 1 up and 5 to the right
A quick way to answer all 1-10 is to multiply the starting price by 1.##. So for number 1 the equation would be 18 x 1.07 which equals $19.26. Question 2 would be
14 x 1.20 which equals $16.80. I think you got it from here.
Answer:
257 is prime.
Step-by-step explanation:
To evaluate if a number is prime, we just need to evaluate it for the prime numbers that are equal or lesser than the said number's square root.
In this case, √257 = 16.03 so we just need to see if 257 is divisible by <u>2, 3, 5, 7, 11 and 13</u> (the prime numbers that come before 16)
- 257 is odd, so it is not divisible by 2.
- The sum of its digits is 14, therefore, it is not divisible by 3.
- 257 ends in 7, therefore it's not divisible by 5.
- 257/ 7 = 36.71 so it's not divisible by 7.
- 257/ 11 = 23.36 so it's not divisible by 11
- Finally 257 / 13= 19.76 so it's not divisible by 13.
Therefore, 257 is prime.
He bought 3 small notebooks (3*7=21) and 3 large notebooks (3*10=30)
21+30=51
Answer:
x=21
Step-by-step explanation:
subtract 6 from both sides get -1/3x=-7
multiply -1/3 or -1/3 as decimal times -7
and get x=21
If brainiest is earned its greatly appreciated. :)
