ANSWER
[tex]- 5x - 3y = 0[/tex]
EXPLANATION
The line that passes through the origin has equation of the form:
y=mx
Where m is the slope.
Since the line is parallel to the line through A(-3, 0) and B(-6, 5), they have the same slope.
The slope is given by:
[tex]m = \frac{y_2-y_1}{x_2-x_1} [/tex]
[tex]m = \frac{5 - 0}{ - 6 - - 3} = - \frac{5}{3} [/tex]
Hence the required equation is:
[tex]y = - \frac{5}{3} x[/tex]
Multiply through by 3,
[tex]3y = - 5x[/tex]
In standard form, the equation is
[tex] - 5x - 3y = 0[/tex]
Answer:
The answer is C. -5x - 3y = 0

Solve for m. 7m + 8 = 8m
Answer:
8
Step-by-step explanation:
7m+8=8m
7m-8m= -8
Whenever you move a number for the opposite side , you change the sign. For example, the number is 6 , then you move it to the other side. The sign becomes negative 6.
-m=-8
The m cannot be a negative sign. So you multiply it by -1 and for -8.
-1(-m)= -1(-8)
m= 8
Double check answer if you want to:
7m+8=8m
Substitute the answer for m.
7(8)+8=8(8)
64=64
So the answer is correct. m=8

If the volume of a sphere is 288πcm3, what is the radius of the sphere in centimeters?
Giving brainliest and 30 points!
The formula for volume of a sphere is 4/3 x PI x r^3
Solve for r:
288PI = 4/3 x PI x r^3
Divide both sides by PI:
288 = 4/3 x r^3
Divide both sides by 4/3:
216 = r^3
Take the cubic root of 216 for r:
r = ∛216
r = 6
The radius is 6 cm.

From the question, we have the following parameters that can be used in our computation:
The graph
A linear equation is represented as
y = mx + c
Where
m = slope
c = y-intercept
From the graph, we have the point (0, 4)
This means that
c = 4
So, we have
y = mx + 4
Using the point (-2, 0) on the graph, we have
-2m + 4 = 0
This gives
2m = 4
m = 2
Recall that
y = mx + 4
So, we have
y = 2x + 4
Hence. the equation is y = 2x + 4

Which equation represents the line that passes through (-8,11) and (4,7/2)?
Answer:
y = -5/8x +6
Step-by-step explanation:
First we need to find the slope
m = (y2-y1)/ (x2-x1)
= (7/2 -11)/(4--8)
= (7/2 - 22/2)/(4+8)
= (-15/2)/(12)
= -15/24
Divide top and bottom by 3
-5/8
Then we can use point slope form to write the equation
y-y1 = m (x-x1)
y- 11 =-5/8(x--8)
y- 11 =-5/8(x+8)
Distribute
y-11 =-5/8 x -5
Add 11 to each side
y-11 = -5/8x -5+11
y = -5/8x +6

answer for this question is 3.85 units squared
Answer:
[tex]\boxed{\text{38.5 units}^{2}}[/tex]
Step-by-step explanation:
The polygon is a trapezoid on its side.
The formula for the area of a trapezoid is
A = ½(a + b)h,
where a and b are the lengths of the parallel sides and h is the distance between them.
AD = a = 2 – (-2) = 2 + 2 = 4 units
BC = b = 2 – (-5) = 2 + 5 = 7 units
AB = h = 3 – (-4) = 3 + 4 = 7 units
A = ½(4 + 7) × 7 = ½ × 11 × 7 = 38.5 units²

2x - 9y=14
[tex]2x - 9y = 14 [/tex]
Answer:
Step-by-step explanation:
first draw you line down on the equal sign take 2x and devide itso it should be 14/2 you should get 7 2x is no longer there then bring down 9y and add d to 14 thats 23 so its x =23
We need to solve for x.
2x - 9y = 14
Move the 9y to the right side and use inverse operations.
2x = 14 + 9y
Divide both sides of the equation by 2.
x = 7 + 9/2y or x = 7 + 4.5y

My assumption is that you'd graph this as a horizontal line at (0,-2) but PLEASE double check with your teacher/instructor because I'm not sure if I'm right.
Hope this helped!
Step-by-step explanation:
Answer:
Step-by-step explanation:
You'll need to share the graphs mentioned in this problem statement.
One can solve 2y + 4 = 0 for y and thus obtain an equation which is easy to graph:
2y + 4 = 0 becomes
2y = -4, or
y = -2
The graph of this function is the horizontal line y = -2. Find (0, -2) on your set of coordinate axes and plot a dark dot there. Then draw a horizontal line thru it. This line has a slope of zero (0) and a y-intercept of -2.

The number of commuters to number of paelinf spots at a given station.
The Metro-North Station of Greenwich, CT, has 2804 commuters. Find the predicted number of parking spots at the Metro-North Station.
A.) 1057 spots
B.) 2894 spots
C.) 6637 spots
D.) 1237 spots
Answer:
D.) 1237 spots
Step-by-step explanation:
We have been given the following regression line;
y= 89.5 + 0.409x
It is reasonable to argue that the number of commuters determines the number of parking spots and as such commuters is our explanatory variable (x). On the other hand, the number of parking spots is our response or dependent variable (y).
We are required to predict the number of parking spots at the Metro-North Station of Greenwich which has 2804 commuters. We are simply asked to determine the value of y when x is 2804 using the regression line;
y = 89.5 + 0.409(2804)
y = 1236.336
y = 1237

A triangle ABC is inscribed in a circle, such that AB is a diameter. What are the measures of angles of this triangle if: measure of arc AC = 70°.
Answer:
Part 1) The measure of angle C is 90°
Part 2) The measure of angle B is 35°
Part 3) The measure of angle A is 55°
Step-by-step explanation:
we know that
The inscribed angle is half that of the arc it comprises.
step 1
Find the measure of angle C
The diameter divide the circle into two equal parts
so
If AB is a diameter
arc AB=180°
∠C=(1/2)[arc AB]
∠C=(1/2)[180°]=90°
step 2
Find the measure of angle B
arc AC=70°
∠B=(1/2)[arc AC]
∠B=(1/2)[70°]=35°
step 3
Find the measure of angle A
The sum of the internal angles of a triangle must be equal to 180 degrees
so
∠A+∠B+∠C=180°
substitute
∠A+35°+90°=180°
∠A=180°-(35°+90°)
∠A=55°
a parallelogram has one side that is 9 millimeters and one side that is 13 millimeters. What is the perimeter of the parallelogram?
Answer: The answer would be 44 millimeters.
Step-by-step explanation: A parallelogram has to sets of congruent sides. One set has two sides that are 9 millimeters and the other set has two sides that are 13 millimeters. 9+9 = 18, 13+13= 26 and 18+26= 44!
Final answer:
To calculate the perimeter of the parallelogram with sides of 9 millimeters and 13 millimeters, you add the lengths of opposite sides and multiply by 2. The perimeter is 44 millimeters.
Explanation:
The perimeter of a parallelogram is calculated by adding the length of all four sides. Since a parallelogram has opposite sides that are equal in length, if one side is 9 millimeters and another side is 13 millimeters, the other two sides will also be 9 millimeters and 13 millimeters respectively. The formula to find the perimeter (P) is P = 2(a + b), where a and b are the lengths of the sides.
Using this formula:
Let a = 9 mm and b = 13 mm.
Then, P = 2(9 mm + 13 mm).
P = 2 × 22 mm.
P = 44 mm.
Therefore, the perimeter of the parallelogram is 44 millimeters.

A rectangular solid has sides of 10 cm, 6.5 cm, and 8.3 cm. What is its volume and surface area? Volume (to the nearest tenth) = cm3 Surface area (to the nearest tenth) = cm2
Answer:
V = 539.5 cm³SA = 403.9 cm²Step-by-step explanation:
The formula of a volume of a rectangular prism:
V = lwh
The fomula of a surface area of a rectangular prism:
SA = 2(lw + lh + wh)
l - length
w - width
h - height
We have l = 10cm, w = 6.5cm and h = 8.3cm. Substitute:
V = (10)(6.5)(8.3) = 539.5 cm³
SA = 2[(10)(6.5) + (10)(8.3) + (6.5)(8.3)] = 2(65 + 83 + 53.95)
= 2(201.95) = 403.9 cm²

if random samples (of size n) students are taken from a specific school district Michigan and asked about their school involvement what conclusions can we expect to draw from samples?
A we can use the sampling distribution to infer about the behavior of all students in the specific district
B we can use a sampling distribution to infer about the behavior of all students in the Michigan
C we can use the sampling distribution to infer about the behavior of all students in the neighboring school district
D we can use the sampling distribution to infer about the behavior of our students in the US
Answer:
A we can use the sampling distribution to infer about the behavior of all students in the specific district
Step-by-step explanation:
A sample is usually studied or analyzed in order to make inference about the population. It will be more time consuming and costly to study the entire population due to the large number of participants.
In our case, the samples are obtained from a specific school district Michigan. This implies that the researcher is interested in this particular school district and is thus our population of interest. Therefore, we can use the sampling distribution to infer about the behavior of all students in the specific district
We can use the sampling distribution to infer about the behavior of all students in the specific district

What can he conclude about the distributions?
They are similar.
They are different.
They are identical.
They are somewhat similar.
Answer:
"They are similar"
Step-by-step explanation:
The means-to-MAD ratio tells how similar two distributions are to each other.
If the ratio is
< 1, this means they are similar
between 1 and 2.5, they are somewhat similar
> 2.5, this means they are different
We see the ratio given is 0.8, which is < 1, so the distributions are similar.
