Answer:
f(g(x)) = 5(3x + 7)
Step-by-step explanation:
f(x) = 5x + 11g(x) = 3x + 2Solving f(g(x))
f(g(x))f(3x + 2)f(3x + 2) = 5(3x + 2) + 11f(3x + 2) = 15x + 10 + 11f(3x + 2) = 15x + 21f(3x + 2) = 5(3x + 7)f(g(x)) = 5(3x + 7)Answer:
[tex]f(g(x)) = 3(5x + 7)[/tex]
Step-by-step explanation:
Step 1: State the eqautions
[tex]f(x) = 5x + 11[/tex]
[tex]g(x) = 3x + 2[/tex]
Step 2: Insert the equation and solve
[tex]f(g(x)) = 5(g(x)) + 11[/tex]
[tex]f(3x + 2) = 5(3x + 2) + 11[/tex]
[tex]f(3x + 2) = 15x + 10 + 11[/tex]
[tex]f(3x + 2) = 15x + 21[/tex]
[tex]f(g(x)) = 15x + 21[/tex]
Step 3: Simplify completely
[tex]f(g(x)) = 15x + 21[/tex]
[tex]f(g(x)) = 3(5x + 7)[/tex]
Answer: [tex]f(g(x)) = 3(5x + 7)[/tex]

Answer: A
Step-by-step explanation:
anthony scored 8 goals in the second round. this made his total score 39. how many points did he score in the first round
Answer:
He had 31 points in the first round.
Step-by-step explanation:
Answer:
39-8= 31
Step-by-step explanation:
let the first round be x
second round =8
first round + the second round = 39
therefore, x+8=39
collect like terms
x= 39-8= 31.
so the answer is 31

Renee is buying Halloween candy. She wants to buy candy bars and lollipops and spend no more than $28. Each candy bar costs $0.45 and each lollipop costs $0.25. Which inequality represents the possible combinations of x, the number of candy bars, and y, the number of lollipops Renee can buy?
The inequality that represents the possible combinations of candy bars and lollipops that he can buy is given by:
[tex]0.45x + 0.25y \leq 28[/tex]
What is the inequality that models this situation?The total price can be no more than $28, hence:
[tex]T \leq 28[/tex]
Each candy bar costs $0.45 and each lollipop costs $0.25. x is the number of candy bars and y of lollipops. Hence, the total price is given by:
T = 0.45x + 0.25y.
Hence, the inequality that models the situation is:
[tex]0.45x + 0.25y \leq 28[/tex]

What is the solution of 4+ 5x+66 = x+ 10? O x = -10 Ox=3 O x=-10 or x = 3 O no solution
Hey there!
4 + 5x + 66 = x + 10
70 + 5x = x + 10
5x + 70 = x + 10
SUBTRACT x to BOTH SIDES
5x + 70 - x = x + 10 - x
5x + 70 - 1x = 1x + 10 - 1x
SIMPLIFY IT!
4x + 70 = 10
SUBTRACT 70 to BOTH SIDES
4x + 70 - 70 = 10 - 70
SIMPLIFY IT!
4x = -60
DIVIDE 4 to BOTH SIDES
4x/4 = -60/4
SIMPLIFY IT!
x = -60/4
x = -15
Therefore, your answer is: x = -15
Good luck on your assignment & enjoy your day!
~Amphitrite1040:)
Answer:
x = -15Step-by-step explanation:
Given :
4 + 5x + 66 = x + 10#1 : Combine like terms on each side.
4 + 5x + 66 = x + 105x + 70 = x + 10#2 : Subtract x from each side.
5x + 70 - x = x + 10 - x4x + 70 = 10#3) Subtract 70 from each side.
4x + 70 - 70 = 10 - 704x = -60#4) Divide 4 from each side.
4x/4 = -60/4x = -15Solution : x = -15

You have a coin and a bag of marbles. The bag of marbles has 5 marbles of each color: Red, yellow, blue and green. What is the probability of flipping a head and then selecting a blue marble?
Answer:
[tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Since there are a total of 4 colors, and there are 5 of each colors, the total marbles in the bad would be;
5 x 4 = 20
If a color is selected at random the probability would be
[tex]\frac{part}{whole}[/tex]
our part is 5
our whole is 20
so the probability would be;
[tex]\frac{5}{20}[/tex] or [tex]\frac{1}{4}[/tex] when reduced

1st q pls help i dont under stand how the answer is 12000
Answer:
See below
Step-by-step explanation:
1/3 (300000) = 100 000 80% of this = 80 000
2/5 (300000) = 120000 125% of this = 150 000 total so far = 230 000
Overall 10% profit would yield 300000(1.1) = 330 000
the remaining land needs to sell for
330 000 - 230000 = 100 000

5/14 x 7/30Solving
This can easily be solved by using cross-multiplicationIf we are given a fraction a/b, it can be rewritten as a x 1/b⇒ 5 x 1/14 x 7 x 1/30Now combine (7 and 1/14) and (5 and 1/30)⇒ 7 x 1/14 x 5 x 1/30⇒ 7/14 x 5/30⇒ 1/2 x 1/6⇒ 1/12Answer:
[tex]\dfrac{1}{12}[/tex]
Step-by-step explanation:
Rewrite the denominators as products of factors, then cancel the common factors.
[tex]\begin{aligned}\dfrac{5}{14} \times \dfrac{7}{30} & =\dfrac{5}{2 \cdot 7} \times \dfrac{7}{6 \cdot5}\\\\ & = \dfrac{5 \cdot 7}{2 \cdot 7 \cdot 6 \cdot 5}\\\\ & = \dfrac{1}{2 \cdot 6}\\\\ & = \dfrac{1}{12}{\end{aligned}[/tex]

Fractions are sometimes the same as dividing, for this case, that rule applies.
[tex]\frac{50}{6}\\\\\frac{11}{5}[/tex]
↑ These improper fractions translate to...
[tex]\frac{50}{6} = 8\frac{1}{3} -- > 8\frac{2}{6} \\\\ \frac{11}{5} = 2\frac{1}{5}[/tex]
Answer:
1) D. 8 2/6 hotdogs
2) B. 2 1/5 cakes
Step-by-step explanation:
1) If she's dividing 50 hotdogs equally among 6 people, then you would divide 50 by 6 to find how many each person gets.
note: 50 ÷ 6 is the same as [tex]\frac{50}{6}[/tex].
[tex]\frac{50}{6}[/tex] = [tex]8\frac{2}{6}[/tex]
6 can go into fifty 8 times, so there is a whole number of 8. There is 2/6 left over, so the final result is [tex]8\frac{2}{6}[/tex].
2) If Sako makes 11 cakes and wants to share it equally among 5 people, we can divide 11 by 5 to find how many each person gets.
[tex]\frac{11}{5} =2\frac{1}{5}[/tex]
5 can go into eleven 2 times, so there is a whole number of 2. There is 1/5 leftover, so the final result is [tex]2\frac{1}{5}[/tex].
Hence, the answers are D, and B.
hope this helps!
