In order to find the value of g(4)+f(-3), we must substitute those values into the functions first.

Substitute -3 into f(x).

f(x)=x²

f(-3)=(-3)²

f(-3)=9

Substitute 4 into g(x).

g(x)=2x-3

g(4)=2(4)-3

Using the rules of PEMDAS, multiply first then subtract.

g(4)=8-3

g(4)=5

Therefore, if f(-3) is 9 and g(4) is 5, we must add the two values together.

5+9=14

<u>The value of g(4)+f(-3) is 14.</u>

Elena L [17]

Answer:

1: 2003

2: 1425

3: 2018

Step-by-step explanation:

1: 875 = 275x + 50.

875 - 50 = 275x + 50 - 50.

825 = 275x

825 ÷ 275 = 275x ÷ 275.

x = 3

2: y = 275(5) + 50.

y = 1425

3: 5,000 = 275x + 50.

5,000 - 50 = 275x + 50 - 50.

4,950 = 275x.

4,950 ÷ 275 = 275x ÷ 275.

x = 18.

I hope this helped and if it did I would appreciate it if you marked me Brainliest Thank you and have a nice day!

The sum of two numbers is 30. If three times the smaller number is equal to two times the bigger one, find the numbers. ​
MAVERICK [17]
  • Let the smaller number be x and the bigger number be y.
  • Therefore, 3x = 2y =  > x =  \frac{2y}{3}x + y = 30 \\  =  >  \frac{2y}{3}  + y = 30 \\  =  >  \frac{2y + 3y}{3}  = 30 \\  =  >  \frac{5y}{3}  = 30 \\  =  > y =  \frac{30 \times 3}{5}  \\  =  > y = 18
  • Therefore, the smaller number = 30 - 18 = 12

Solve the system 2x + 2y = −6 and 3x − 2y = 11 by using graph paper or graphing technology. What is the solution to the system?
n200080 [17]
In equation 1, When x = 0, y = -3 ( 0, -3) And when y = 0, x = -3....( 3,0) In equation 2, when x = 1, y = -4(1,-4) and when y = 2, x = 5....(5,2) You have to plot the points on graph paper and the solutions are where the two lines intersect. You can use any points for x and y.
