Answer:
1) -43 2)-10
Step-by-step explanation:
so for the first one you would enter -9 into all of the x's
g(x)=4x-7
g(-9)=4(-9)-7 ( you would get -36, then you would minus y. so the answer is -43!)
g(-9)=-43
second one would be the same thing
g(x)=x^2-4x+11
g(-4)=-7^2-4(-7)+11
g(-4)=-10

Why is 64 a perfect square, but 60 is not?
Answer:
Step-by-step explanation:
because it needs to be a number times itself to be be a perfect square
Answer:
The square root of 64 gives the original number. If you square 8, you get 64, making it a perfect square. However, 60's square root is only approximate to 60 and very close to it when squared. Therefore, it cannot be a perfect square.

3. use the diagram shown to calculate m
Answer: 131
Step-by-step explanation:
The angle A inside the triangle is
180-162 = 18 degrees
The measure of angle N inside the triangle is
180 - 149 = 31 degrees
Now, since we have the inside angles we can find ang P
Inside Ang A + Inside Ang N + Ang P = 180
18 + 31 + P = 180
49 + P = 180
P = 180 - 49
P = 131 degrees

CAN SOMEONE PLEAEE HELP ????!!!!!! I will mark Brianliest !!!!!!!!!!!!!!!!!!
Answer:
I don't know if I'm correct but the answer is 6.
Step-by-step explanation:
I'm not 100% correct, but you set the other two angles to add to each other then set it equal to angle QRS and i got x=6.
Your equation should be like this: 3x + 17 + 2x +21 = 10x -1
than you solve form there
I;m not sure that this is the correct answer and maybe i'm wrong, but hope this helps
Answer:
59°
Step-by-step explanation:
According to the given description, [tex] \angle QRS[/tex] is the exterior angle of [tex] \triangle PQR[/tex]
So, by exterior angle property of a triangle, we have:
[tex] m\angle QRS=m\angle RPQ+m\angle PQR\\\\
(10x - 1)\degree = (3x +17)\degree+(2x +12)\degree\\\\
(10x - 1)\degree = (3x +17+2x +12)\degree\\\\
(10x - 1)\degree = (5x +29)\degree\\\\
(10x - 1)= (5x +29)\\\\
10x - 5x = 29 + 1\\\\
5x = 30\\\\
x = \frac{30}{5}\\\\
x = 6\\\\
\because m\angle QRS = (10x - 1)\degree \\\\
\therefore m\angle QRS = (10\times 6- 1)\degree \\\\
\therefore m\angle QRS = (60- 1)\degree \\\\
\huge\orange{\boxed{\therefore m\angle QRS = 59\degree }}\\

choose the number that is larger than: 1.11 x 10 a.90,000,000,000 b.5.66 x 10 c.1.01 x 10 d.1.01 x 10
This number is greater than our solution to 1.11 * 10^12.
What are exponent and examples of them?
The number of times a number has been multiplied by itself is referred to as an exponent. For instance, the expression 2 to the third (written as 23) signifies 2 x 2 x 2 = 8. 23 and 2 x 3 = 6 are not equivalent. Keep in mind that any number is itself when raised to the power of 1.First we need to find the value of 1.11 * 10^12.
We need to solve the exponent first.
10^12 = 1000000000000
Next, we will multiply this by 1.11.
1,000,000,000,000 * 1.11 = 1,110,000,000,000
The value of 1.11*10^12 is equal to 1,110,000,000,000.
We can immediately rule out a), 90,000,000,000 as an answer. We can easily tell that out solution is greater than this answer.
Now we will find the value of option b).
5.66 * 10^11.
We need to solve the exponent first.
10^11 = 100000000000
Next, we will multiply this by 5.66.
100,000,000,000 * 5.66 = 566,000,000,000
This number is not greater than our solution to 1.11 * 10^12. Therefore, option b) is not your answer.
Now we will find the value of option c).
1.01 * 10^13.
We need to solve the exponent first.
10^13 = 10,000,000,000,000
Next, we will multiply this by 1.01.
10,000,000,000,000 * 1.01 = 10,100,000,000,000
This number is greater than our solution to 1.11 * 10^12. Therefore, option c) is your answer.

Choose the number that is larger than: 1.11 x 10 to the 12 power A. 90,000,000,000 B. 5.66 x 10 to the 11th power C. 1.01 x 10 to the 13th power D. 1.01 x 10 to the 12 power
A swimming pool can be filled with water in 16 hours using 2 pumps. How many hours would it take if 8 pumps were used?
Which equation has 1 solution.
A. 10x + 2x = (10 + 2)x - 2
B. 10x + 2 = (10 + 2)x - 2x
C. 10x + 2x = (10 + 2)x
D. 10x + 2 = (10 + 2)x
Answer:
We conclude that 10x + 2 = (10 + 2)x has only 1 solution.
Hence, option (D) is correct.
Step-by-step explanation:
A.
10x + 2x = (10 + 2)x - 2
Checking the equation in Part A
10x + 2x = (10 + 2)x - 2
10x + 2x = 10x+2x-2
10x + 2x - 10x - 2x = -2
0 = -2
The sides are not equal.
Hence, NO SOLUTION!
B.
10x + 2 = (10 + 2)x - 2x
Checking the equation in Part B
10x + 2 = 10x+2x - 2x
10x + 2 - 10x - 2x + 2x = 0
2 = 0
The sides are not equal.
Hence, NO SOLUTION!
C.
10x + 2x = (10 + 2)x
Checking the equation in Part C
10x + 2x = 10x+2x
10x + 2x - 10x - 2x = 0
0 = 0
Both sides are equal.
It is true for all x.
D.
10x + 2 = (10 + 2)x
Checking the equation in Part D
10x + 2 = 10x+2x
10x - 10x - 2x = -2
-2x = -2
Divide both sides by -2
x = 1
Hence, 10x + 2 = (10 + 2)x has only 1 solution.
Therefore, we conclude that 10x + 2 = (10 + 2)x has only 1 solution.
Hence, option (D) is correct.

Three different coins are tossed. What is P(tail, head or tail, head, or tail)
Answers:
Probability of landing all three coins on head: [tex]\frac{1}{8}[/tex]
Probability of landing all three coins on tail: [tex]\frac{1}{8}[/tex]
Probability of landing two coins on head and one on tail: [tex]\frac{3}{8}[/tex]
Probability of landing two coins on tails and one on head: [tex]\frac{3}{8}[/tex]
Step-by-step explanation (Read Carefully):
-How to calculate this is that there are three possible outcomes when tossing the three coins. So, if you group all the possible outcomes of heads and tails when tossing the three coins in one event, you’ll get eight events. Let’s take a look at it:
-A way to organize this is to have:
H = heads
T = tails
-Total of eight events, where each event is the probability of the three coins being tossed (possible events with equal probability, and order matters):
HHH
HHT
HTH
HTT
THH
THT
TTH
TTT
Now, let’s apply some questions:
⇒ Probability of landing all three coins on heads: [tex]\frac{1}{8}[/tex]
Explanation: Look at the events above. How many times (out of the eight events) that all three coins land on heads? Well, you can see that there is only one possible event that has HHH. So, the probability of landing all three coins on heads (out of the eight events) is [tex]\frac{1}{8}[/tex].
⇒ Probability of landing all three coins on tails: [tex]\frac{1}{8}[/tex]
Explanation: Look at the events above. How many times (out of the eight events) that all three coins land on tails? Well, you can see that there is only one possible event that has TTT. So, the probability of landing all three coins on tails (out of the eight events) is [tex]\frac{1}{8}[/tex].
⇒ Probability of landing two coins on heads and one on tails: [tex]\frac{3}{8}[/tex]
Explanation: Look at the events above. How many times (out of the eight events) where two coins land on heads and one on tails? Well, you can see that there are three possible events that include HHT, HTH, THH. So, the probability of landing two coins on heads and one on tails (out of the eight events) is [tex]\frac{3}{8}[/tex].
⇒ Probability of landing two coins on tails and one on heads: [tex]\frac{3}{8}[/tex]
Explanation: Look at the events above. How many times (out of the eight events) where two coins land on tails the one on heads? Well, you can see that there are three possible events that include HTT, THT, TTH. So, the probability of landing two coins on tails and one on heads (out of the eight events) is [tex]\frac{3}{8}[/tex].

The location of Sam's house, the library, and the gas station are shown on the map below.
Based on the map, what is the shortest distance, to the nearest tenth, from the Library to the Gas Station if each unit represents one mile?
It is found that location of Sam's house is at a distance of approximately 8.062 meters far from the gas station.
What is the distance between two points ( p,q) and (x,y)?The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:
D = √[(x-p)² + (y-q)²]
Sam's house S(x, y) = (2, -4)
Library L(x, y) = (-5 , 2)
Gas station G(x, y) = (3, 4)
The distance d, in miles, is determined by the line segment distance formula:
D = √[(x-p)² + (y-q)²]
It is used in an operation known as dot product.
Then the distance between Sam's house and the Gas station is:
D = √[(2 - 3)² + (-4 -4)²]
D = 8.062 meters
Hence, The location of Sam's house, is at a distance of approximately 8.062 meters far from the gas station.
