Give your answer as an ordered triple.
Answer:
(1, 0, 2)
Step-by-step explanation:
[3 -1 2 | 7 ]
|6 -10 3 | 12|
[1 -1 4 | 9 ]
To the first row, add -3 times the values of the third row
To the second row, add -6 times the values of the third row
[0 2 -10 | -20 ]
|0 -4 -21 | -42 |
[1 -1 4 | 9 ]
To the second row, add 2 times the values in the first row
[0 2 -10 | -20 ]
|0 0 -41 | -82 |
[1 -1 4 | 9 ]
z = -82 / -41
z = 2
2y - 10(2) = -20
y = 0
x - 0 + 4(2) = 9

Brent needs to paint a logo made using two right triangles. The dimensions of the logo are shown below. What is the difference between the area of the large triangle and the area of the small triangle?
Two right triangles are attached along their longest side. The smaller triangle has height 6 cm and base 2 cm. The height of the larger triangle is 9 cm and its base is 5 cm.
4.5 cm2
8.5 cm2
16.5 cm2
33.0 cm2
9514 1404 393
Answer:
(c) 16.5 cm^2
Step-by-step explanation:
The area of each triangle is given by the formula ...
A = 1/2bh
Smaller triangle area = (1/2)(2 cm)(6 cm) = 6 cm^2
Larger triangle area = (1/2)(5 cm)(9 cm) = 22.5 cm^2
The difference in area is ...
22.5 cm^2 -6 cm^2 = 16.5 cm^2

what is the average rate of change from 2 to 9 of the function represented by the graph?
Answer:
-3/7
Step-by-step explanation:
It is asking to find the slope of the secant line going through points (2,f(2)) and (9,f(9)).
We must find f(2) by looking at the curve at x=2. We should see that y=2 there so f(2)=2.
We must find f(9) by looking at the curve at x=9. We should see that y=-1 there so f(9)=-1.
The slope of a line is calculated by finding the ratio of the change of y to the change of x.
(-1-2)/(9-2)
(-3)/(7)
-3/7

Which expression is equivalent?
On edge
Answer: Choice B
[tex]x^{1/8}y^{8}[/tex]
======================================================
Explanation:
The two rules we use are
[tex](a*b)^c = a^c*b^c[/tex]
[tex](a^b)^c = a^{b*c}[/tex]
When applying the first rule to the expression your teacher gave you, we can say that:
[tex]\left(x^{1/4}y^{16}\right)^{1/2} = \left(x^{1/4}\right)^{1/2}*\left(y^{16}\right)^{1/2}[/tex]
Then applying the second rule lets us say
[tex]\left(x^{1/4}\right)^{1/2}*\left(y^{16}\right)^{1/2} = x^{1/4*1/2}*y^{16*1/2} = x^{1/8}y^{8}[/tex]
Therefore,
[tex]\left(x^{1/4}y^{16}\right)^{1/2} = x^{1/8}y^{8}[/tex]
-------------
In short, we just multiplied each exponent inside by the outer exponent 1/2.
So that explains why the exponents go from {1/4,16} to {1/8,8} for x and y in that exact order.
if x^3+ax^2+bx=6 is exactly divisible by (x-1), prove that a+b=5.
Step-by-step explanation:
x-1=0
x=1
subtitute value of x
p(x)=x^3+ax^2+bx
p(1)=(1)^3+a(1)^2+b(1)
p(1)=1+a+b
as p(x) =6. (given)
1+a+b=6
a+b=6-1
a+b=5

Jenna has

131131 dog biscuits. She wants to give them as gifts to each of her
4
44 poodles.
Hi! I'm happy to help!
To solve for how many biscuits each poodle gets, we have to split or divide the amount of biscuits by the amount of poodles. (We will use division)
131,131,131÷444
295,340.3851... rounded to 295,340
So, each poodle will receive 295,340 dog biscuits. (A LOT)

Round this number to the nearest 100,000
927,545
Answer:
900,000
Step-by-step explanation:
rounding is quite simple, the number 927,545, like all numbers, has different number places/values. the number 9 is in the 100,000th place and to round you look at the number in the place to the right of it which is 2. the number 2 is is less than 5 so it can't raise the number 9 to a ten. because of this, it reduces all of the other numbers to 0. leaving you with the number 900,000

Answer:
It should be 12, but x wasn't defined. My condition could be wrong though.
If the area of the square above is 144. The value of x is the length of the side of the square which is 12 units.
What is the area of a square?The area of a square can be calculated as the square of the sides of a given figure.
The area of a square = side x side
We have given the area of the square above is 144.
Let x be the side of the given square.
The area of a square = side x side
[tex]144 = x \times x\\\\144 = x^2\\\\x =\sqrt{144} \\\\x = 12[/tex]
Hence, the length of the side is 12 units.

36. What number shows a temperature of 9° below zero?
Answer:
-9*
Step-by-step explanation:
1. anything below zero is negative
2.if you say a positive temperature such as this example (9) then say below zero it is is always going to be a negative temperature
A temperature of 9° below zero is represented by the number -9.
The negative sign indicates that the temperature is below zero on the Celsius or Fahrenheit scale. It means that the actual temperature is 9 degrees lower than the freezing point of water. For example, if the freezing point is 0°C, a temperature of -9°C would indicate that it is 9 degrees below freezing.
Similarly, on the Fahrenheit scale, a temperature of -9°F would indicate that it is 9 degrees below the freezing point of 32°F. Negative temperatures signify colder conditions than the reference point of zero degrees.
Therefore, a temperature of 9° below zero is represented by the number -9.
