-6x - 4y = -32
-2x + 7y = 6
A. (5, 3)
B. (5, 2)
C. (4, 3)
D. (4, 2)
Answers
Answer:
D
Step-by-step explanation:
-6x=4y-32
x=(2(2y-16))/-6
x=(2y-16)/-3
x=(-2/3)*y+16/3
solve for y:
-2((-2/3)*y+16/3)+7y=6
(4/3)y+21/3y+(-32/3)=18/3
(25/3)y=(18+32)/3
(25/3)y=50/3
25y=50
y = 2
solve for x:
-6x - 4y = -32
-6x - 8 = -32
-6x = -24
x = 4
answer: (4, 2)

Answer:
Im pretty sure its C... Step-by-step explanation: what im seeing here is 10 with the small numbers in front so it looks like scientific notation, Maria has 1 million because 1 x a number = that number, 10 multiplied by itself 6 times equals 1 million, 10 x10 = 100 x 10 = 1000 x 10 = 10,000 x 10 = 100,000 x 10 = 1,000,000. so from this we know what Larry's 10 to the power of 5 is, we need to know what 100,000 x whatever equals. If im doing this right, Larry's number is 1 million 2 hundred thousand which is greater than 1 million. (sorry if the explanation is wanky and sorry if it was wrong, im new to brainly.)

Select all the expressions that show the distance between points A and B
Answers
Answer:
I believe the answer is D, but im not quite certain, let me know if im wrong. Hope this helps!
Step-by-step explanation:
The expressions, that show the distance between points A and B, are 8 -1 and |-8| -|-1|.
What is distance?The separation between two points the coordinates of two points in space are used in the formula. In coordinate geometry, a two-dimensional or three-dimensional space can be used to calculate the distance between two points using the distance formula. The Pythagoras theorem is sometimes used to calculate the distance between two places.
The length of the line segment bridging two points on a plane is known as the distance between the points.
In the given line:
Position of point A is -8.
Position of point B is -1.
Hence, distance between A and B is = | -1 - (-8) | unit = 7 unit.
Expression 8 -1 = 7
and |-8| -|-1|. = 7.
Hence, these two expressions how the distance between points A and B.

Answers
Answer:
See below.
Step-by-step explanation:
a) $81235 - $15405 = $65830
b)
1) The graph uses cubes to represent the amount of sales.
2) I wonder if the amount of sales is proportional to the length of the side of the cube or to the volume of the cube.
c)
Using a ruler, the Year 1 cube has side length 5 units.
Using the same ruler, the Year 5 cube has side length 18 units.
The volume of the Year 5 cube is 5832 units³. The volume of the Year 1 cube is 125 units³.
The ratio of the volumes of Year 5 cube to the Year 1 cube is
5832/125 = 47:1
The ratio of sales of Year 5 to Year 1 is
81235/15405 = 5:1
The sales of Year 5 are approximately 5 times the sales of Year 1, tbut the cube of Year 5 has approximately 47 times the volume of the cube of Year 1. The graph is misleading because the volumes of the cubes are not proportional to the amounts of sales.
d) 47 times in volume

Answer:
Y= mx + b
so Y = 1/3x + 2
just substitute
Now, we shall use points (3,2) as the substitutes for the solution for b, which 3 would be the input and 2 would be y.
Therefore, 2 = 1/3(3) + b
2 = 1 + b, therefore, one would be subtracted from 2 which would give us the answer of b equaling to one. Thus, y = 1/3x + 1

Answer:
[ 2] − | −5 + 7 |
Step-by-step explanation:
Since we know that | −5 + 7 | is an absolute value, we know that the answer will be positive no matter what.
Step 1) Solve. | −5 + 7 | = 2.
Step 2) Find which other absolute value is equal to -2.
After solving [2], − | −5 + 7 | = -2, we know that the answer is choice 2.
We know this because | −5 + 7 | = 2, however, since it is multiplied by (-), it becomes -2. And 2 + (-2) = 0
We start by simplifying | −5 + 7 |:
| −5 + 7 | = | 2 | = 2
Now we can simplify each of the answer choices:
[2] | +5 − 7 | = | −2 | = 2
[3] | −( −5 + 7 ) | = | 2 | = 2
[4] | 7 − 5 | = | 2 | = 2
We see that only choice [2], when added to | −5 + 7 |, will equal zero:
2 + (−2) = 0
Therefore, the answer is [2] | +5 − 7 |.
Mrs. Summers polled the students in her 7th and 8th grade classes to determine the number of pets each student has at home. The results for both classes are shown in the dot plots below. Calculate the mean and mean absolute deviation of each sample. Then, complete the following question.

A. higher, lower?
B. same as, twice, half?
Answers
Answer: A
Step-by-step explanation: mean in math terms mean everything added together on a graph we now have an 8th grade class and a 7th grade class the 7th-grade class has 67 pets 6+14+15+16+10+6=67 and the 8th-grade class has 121 pets 3+8+21+36+35+18=121 so it would be A.
the mean number of pets for the 8th-grade class is about 1.4 pets higher than the mean number of pets for the 7th grade class. This different is about lower the mean absolute deviation of either group.

Step-by-step explanation:
By observation, we can see very clearly that NR and QS are neither parallel nor perpendicular. Hence we can ignore A and B.
We notice that VT and VU are the same length.
Hence we can conclude that NR and QS must also be the same length (i.e they are congruent)
Therefore C is the answer.

A right rectangular prism has length 3 1/3 , width 2 1/3 , and height 1 1/3 . You use cubes with fractional edge length 1/3 to find the volume. How many cubes are there for each of the length, width, and height of the prism? Find the volume.
Answers
For the length, we have:
3 1/3 ÷ 1/3 = 10
So there are 10 cubes along the length of the prism.
For the width, we have:
2 1/3 ÷ 1/3 = 7
So there are 7 cubes along the width of the prism.
For the height, we have:
1 1/3 ÷ 1/3 = 4
So there are 4 cubes along the height of the prism.
To find the volume of the prism, we can multiply the number of cubes along each dimension.
Volume = length × width × height
Volume = 10 × 7 × 4
Volume = 280 cubic units
So the volume of the prism is 280 cubic units.
