Answer:
The answer to this question is -21.
Step-by-step explanation:
f(g(-3)) says "f at g at -3".
"Evaluating the value of g if x is -3, Then put the value of x into the f function".
g(x) = x - 4
g(-3) = 3x +5
g(-3)=3*(-3)+5
g(-3)=-15+5
g(-3)=-10.
put -10 into the f.
f(x)=2x-1
f(-10)=2*(-10)-1
f(-10)=-20-1
f(-10)=-21.
so f(g(-3))=-21.
Answer:
x = 9/2 y = 0
Step-by-step explanation:
2/3x + 5y = 3 5y = -2/3x + 3 y = -2/15x + 3/5
4/3x - 2(-2/15x + 3/5) = 6
4/3x + 4/15x - 6/5 = 6
8/5x - 6/5 = 6
8/5x = 36/5
x = 9/2
2/3(9/2) + 5y = 3
3 + 5y = 3
5y = 0
y = 0
Answer:
Step-by-step explanation:
A rectangular prism's surface area is 
.
2·(10·5+2·5+2·10)=160.
They both can be divided by 2 to make it 7: 28. Then, it can be divided by 7 to make it 1:4
840 = 70% (100% - 30%)
840 : 70 * 100 =
1200$ is your answer
-----------------------------------
1200 - 30% = 840%
