Answer:
[tex]f(x) = x + 4[/tex]
[tex]g(x) = 3x^2 - 5[/tex]
Step-by-step explanation:
Given
[tex]g(f(x)) = 3(x + 4)^2 - 5[/tex]
Required
Find g(x) and f(x)
Replace all expression in bracket with x
[tex]g(x) = 3(x)^2 - 5[/tex]
[tex]g(x) = 3x^2 - 5[/tex]
The expression removed from bracket are:
f(x) and x + 4
So:
[tex]f(x) = x + 4[/tex]

Answer:
x=16º
Step-by-step explanation:
The sum of angles in a triangle is 180º.
So,
39 + 125 + x = 180

164 + x = 180
x = 180-164
x= 16
5. Alan and Alice play a game of noughts and crosses. From looking at previous games,
the probability of Alan winning is 0.31, the probability Alice will win is 0.45. What is
the probability of a draw?
Answer:
0.24
Step-by-step explanation:
Then the probability of a draw = 1- (p
Pr(Alan) = the probability of Alan winning = 0.31,
Pr(Alice) = the probability Alice will win = 0.45.
We are required to give probability of a draw.
= 1-(pr(alan) + pr(alice)
= 1-0.45+0.31
= 1 - 0.76
= 0.24
We have 24% probability of having a draw.

One computer industry expert reported that there were about 600 million computers in use worldwide in 2001 and that the number was increasing at an annual rate of about 10%. How many computers would there have been worldwide in 2009?
Answer:
In 2009 there would be 1,286,153,286 computers.
Step-by-step explanation:
Given that a computer industry expert reported that there were about 600 million computers in use worldwide in 2001 and that the number was increasing at an annual rate of about 10%, to determine how many computers would there have been worldwide in 2009, the following calculation must be done:
2002 = 600 x 1.1 = 660
2003 = 660 x 1.1 = 726
2004 = 726 x 1.1 = 798.6
2005 = 798.6 x 1.1 = 878.46
2006 = 878.46 x 1.1 = 966.306
2007 = 966.3 x 1.1 = 1,062.9366
2008 = 1,062.93 x 1.1 = 1,169.23026
2009 = 1,169.23026 x 1.1 = 1,286.153286
1,286.153286 x 1,000,000 = 1,286,153,286
Thus, in 2009 there would be 1,286,153,286 computers.

A school group is planning a trip to New York City. There
are 29 people going on the trip. They spent a total of
$19,111. They agreed to share the total cost of the trip
equally. Let "s" equal each person's share of the cost.
What is each person's share of the cost?
Answer:
$659
Step-by-step explanation:
This a basic algebra question with set up.
The total cost is 19,111 with 29 people going and s being each person's cost.
19,111 = 29s
[tex]\frac{19111} {29}[/tex][tex]=s\\[/tex]
so
$659
Answer:
S=$659
Step-by-step explanation:
You have to divide 29 by 29 which give you 1 so cross that out, then do 19111 divided by 29 which is 659, so s=659.
Hope this helps:)

-24d⁵z⁴/ 18d-⁵z⁴
write your answer with only positive exponents
Answer:
-24d^10/18
Step-by-step explanation:
-24d⁵z⁴/ 18d-⁵z⁴
The two z⁴ cancel out, and when dividing exponents you subract them.
d⁵-d-⁵=d^10
Put it all together and you get
-24d^10/18

Changs gas tank is 1/5 full. After he buys 13 gallons of gas, it is 7/10 full. How many gallons can Changs tank hold?
Answer:
26 gallons
Step-by-step explanation:
Set up an equation to represent this problem. Parameter (x) represents the gas tank when it is filled. Based on the problem;
[tex]\frac{1}{5}x + 13 = \frac{7}{10}x[/tex]
Inverse operations;
[tex]\frac{1}{5}x + 13 = \frac{7}{10}x\\-\frac{1}{5}x\\\\13 = \frac{7}{10}x - \frac{1}{5}x\\\\[/tex]
Convert to combine denominator, and simplify,
[tex]13 = \frac{7}{10}x - \frac{1}{5}x\\\\13 = \frac{7}{10}x - \frac{2}{10}x\\\\13 = \frac{5}{10}x\\\\13 = \frac{1}{2}x[/tex]
Inverse operations,
[tex]13 = \frac{1}{2}x\\*2\\\\26 = x[/tex]
26 gallons

Step-by-step explanation:
The parabola is facing upwards and the vertex is (0,1) so the range would be [tex]y \geq 1[/tex].
if the rule is y=2x+3 and the x is 21 what is y
Answer:
45
Step-by-step explanation:
To solve first, plug in 21 for x in the rule, y=2x+3. This makes the rule y=2(21)+3. Then simplify to find y.
Multiply 2 and 21, y=42+3. Next, add, y=45.
[tex]\huge\text{Hey there!}[/tex]
[tex]\large\text{If x = 21}[/tex]
[tex]\large\text{y = 2(21) + 3}\\\large\text{2(21) = 42}\\\large\text{y = 21 + 3}\\\large\text{45 = 42 + 3}\\\large\text{= \bf{\underline{y = 45}}}\\\\\boxed{\boxed{\large\text{Answer: \bf{y = 45}}}}\huge\checkmark[/tex]

solve for t
–9.96 + 9.9t = 1.54 + 7.7t + 7.2t
Answer: -2.3
Step-by-step explanation:
–9.96 + 9.9t = 1.54 + 7.7t + 7.2t
–9.96 + 9.9t = 1.54 + 14.9t
-9.96 - 5t = 1.54
-5t = 11.5
t = -2.3
