Answer:

s+g ≥ 4

s > g/2 + 1

Step-by-step explanation:

Hi, you want to study at least 4 hours.

So, the social studies hours of study (5) plus the English hours of study (e) must be higher or equal to 4 (hours)

s+e≥ 4

The time spent studying social studies(s) must be higher than half the time spent studying English (e/2) plus 1 hour.

s > e/2 + 1

So, the system of inequalities is:

s+e ≥ 4

s > e/2 + 1

The functions f and g are defined as follows.
Troyanec [42]

Answer:

f(-5)= 90, g(7)= -3x+4

Step-by-step explanation:

First Solve f(x)

f(x)= 3×^2-3x

Plug in -5 to the x

3(5)^2-3(-5)

f(x)= 90

Then Solve g(x)

g(x)=-3x+4

Plug in the 7 in the x

g(x)=-3x+4

g(x)=17

Jamie's older brother and his three friends want to split the cost of lunch they also want to leave a 15% tip how much should ea
goldfiish [28.3K]
Answer:
$22.43

Explanation:
We can start by finding the amount that they should tip. The total bill is $78, so we should take 15% of 78 and add it to the total.
0.15 * 78 = 11.7
78 + 11.7 = 89.7
This means that the total cost of the bill, with a tip, is $89.70.
Since there are 4 people, we have to split this total into 4 if they all want to pay equally.
89.70 / 4 = 22.425 = $22.43 !

Hope this helps
