Step-by-step explanation:
f(x)=5x-3
g(x)=5x-4
f(g(x))
f(5x-4)=5(5x-4)-3
25x-20-3
=25x-23
I would appreciate if my answer is chosen as a brainliest answer
Jessica got $0.43. Because 2.89 - 2.46 = 0.43. Hope this helps.
Answer:
12 feet.
Step-by-step explanation:
1 inch = 4 feet.
Multiply 3 by 4.
3×4=12
I multiplied 3 by 4 because 1-inch equals 4 feet, which means if we multiply both terms by 3, you will get 3 inch = 12 feet.
Hope this helps!
2nd equation:
8 x-y=10 ⇒ y= 8 x-10
We will switch that in 1st equation:
8 x-10=x²+12 x+30, or:
x² + 4 x +40 = 0, a=1,B=4, c=40
Discriminant : D= b² - 4 ac= 16 - 160 = -144 and because it is negative there are no real solutions.
Answer: D)
Answer:
