3 < 2x + 1 < 9 How do I solve this?

Mathematics
1 answer:
Vitek1552 [10]3 years ago
5 0

Answer:

(1,4) or 1 < x < 4

Step-by-step explanation:

3 = less than 2x + 1 and 2x + 1 is less than 9

we can split the two parts of the equation

3< 2x + 1 and 2x + 1 < 9

for 3< 2x + 1 x has to be greater than 1

for 2x+ 1 < 9 x has to be less than 4 so the answer is (1,4) or 1 < x < 4

h(n)=-13nh(n)=−13nh, left parenthesis, n, right parenthesis, equals, minus, 13, n Complete the recursive formula of h(n)h(n)h, l
mr Goodwill [35]

Answer:

h(1)=-13

h(n)=h(n-1)-13, n\geq 2

Step-by-step explanation:

We are given that

h(n)=-13n

We have to find the recursive formula of h(n).

Substitute n=1

h(1)=-13

n=2

h(2)=-13-13=-26=h(1)-13

n=3

h(3)=-13(3)=-39=-26-13=h(2)-13

h(4)=-13(4)=-52=-39-13=h(3)-13

:

:

:

h(n)=h(n-1)-13

Therefore, the recursive formula is given by

h(1)=-13

h(n)=h(n-1)-13, n\geq 2

3. How many gallons of ice-cream are produced each<br>week?​
andrezito [222]

Answer:

Each week 26,849,315 Gallons of ice cream is produced each week

Step-by-step explanation:

To find this we see how much is made in a year which is 1.4 billion gallons in the U.S.

To see how much is in a day we divide 1.4 billion by 365. Which is 3835616 Then we multiply it by 7 because there is 7 days in a week and the answer is 26849315
