Where do the slope and y-intercept show up in the tables and graphs?
Answer:
Solution: The general form of the line on a graph is y = mx+c,
where y is the coordinate of the point along the y-axis,
x is the coordinate of the point along the x-axis,
m is the slope of the line or arc tan of the angle the line makes with the x-axis, and
c is the intercept the line makes on the y-axis.
Suppose we want a line having a slope of 45º with the x-axis and passes through point P (4,6), the equation of the line is
y = mx + c
6 = tan 45 * 4 + c, or
6 = 4 + c, or
c = 6–4 = 2.

Determine whether each sequence is a geometric sequence. If yes, then state the common ratio.
5, 10, 15, 20,...
Answer:
Step-by-step explanation:
it is not a geometric sequence
Answer:
no
Step-by-step explanation:
Take the second term and divide it by the first term
10/5 = 2
Take the third term and divide it by the second term
15/10 = 3/2
The ratio is not the same so it is not a geometric sequence
What is the value of the independent variable at point A on the graph?
Answer:
6
Step-by-step explanation:
The independent value refers to the x values of a graph. Point A is located at (6, 3). Therefore, the value of the independent variable is 6.
The value of the independent variable at point A on the graph is 6.
What is Independent Variable?The cause is the independent variable. Its value is unaffected by the other study variables.
In an experimental study, an independent variable is one that you change or alter to examine its effects. It is named "independent" because it is unaffected by any other study variables.
Given:
We have two quantities from the graph one is mass in grams and another is time.
as, the masses totally depends on growth of bay with time.
So, the dependent variable is Mass and independent variable is Time.
Now, the coordinates for Point A is (6, 3).
Hence, the value of point A is 6.

POINTS IF HELP!!! Please help me?
PLEASE HEEELPPP 15 POINTS PLESSEE
Can someone help me with this two because I am very confused
Answer:
Let the height of the larger box = h
and length and width of the larger box = l and w , repectively
Now , Let find the volume of the larger box
Volume = length * width * height
So Volume of the larger box = l*w*h = lwh
Now the question says
the height of the smaller box is 80% of the height of the larger box
It means
Height of the smaller box = 80% of h = 0.80*h = 0.80h
and the other two dimensions are same so it means length and width of the smaller box = l and w
so, Volume of the smaller box = l*w*0.80h = 0.80lwh
So the Difference in the volume of the two boxes = Volume of larger box - Volume of smaller box
therefore , Difference in the Volume of two boxes = lwh - 0.80 lwh = 0.20lwh

Rewrite using a negative exponent.
1/3^2
Answer:
1/9 or 3^-2
Step-by-step explanation:
Ignore the value of 1/3 for now and just focus on the 3^2.
Find 3^2:
3*3 = 9
Now 9 is the denominator, therefore our answer would be 1/9 once you reassemble the fraction.
Because 1/9 is our new fraction, we can use a negative exponent to create the same result. This is because the negative exponent rule tells us that a number with a negative exponent should be put to the denominator. Therefore we can then use 3^-2.
Answer:
3^-2

Find the arc length of the partial circle.
Either enter an exact answer in terms of π or use 3.14 π and enter your answer as a decimal.
Answer:
1/2 pi
Step-by-step explanation:
This is 1/4 of a circle
Find the circumference and multiply by 1/4
1/4 C
1/4 ( 2*pi*r) where r is the radius
The radius is 1
1/2 pi*1
1/2 pi
Answer:
Step-by-step explanation:
A full circle has a circumference of 2*pi * r
r = 1
so Full Circle = 2 * PI
1/4 Circle = 2*pi / 4 = 1/2 pi
The length of the arc length = 1/2 pi
Just in case you prefer the more numerical answer, 1/2 * 3.14 = 1.57
1. Rút gọn biểu thức A(x) = (x+2)(x+3)(x+5) - (x-1)(x+4)(x+7). Từ đó tìm tất cả các giá trị x sao cho A(x) = 0.
x = -29/7
Step-by-step explanation:
A(x) = (x^2 + 5x + 6)(x + 5) - (x^2 + 3x - 4)(x + 7)
= (x^3 + 10x^2 + 31x + 30) - (x^3 + 10x^2 + 17x - 28) = 14x + 58
A(x) = 0 => 14x + 58 =0 => x = -58/14 = -29/7

On the set of axes below, draw the graph of the equation y = -3/4x + 3. Is the point (3, 2) a solution to the equation? Explain your answer based on the graph drawn
(3,2) isn’t a solution because it doesn't satisfy the equation also, the line on the graph doesn’t go through it .
How can we find the solution to an equation?We do same operations on both the sides so that equality of both expressions doesn't get disturbed.
Solving equations generally means finding the values of the variables used in it for which the considered equation is true.
The graph of the equation is given as y = -3/4x + 3.
We have to find if the point (3, 2) a solution to the equation.
So, we will subtitute the point to to satify the equation;
y = -3/4x + 3.
y = -3/4(3) + 3
y = -9 / 4 + 3
y = 3/3 = 1
Thus, (3,2) isn’t a solution because it doesn't satisfy the equation also, the line on the graph doesn’t go through it .

Quadrilateral ABCD is a parallelogram. Let E be a point on AB, and let F$\ be the intersection of lines DE and BC The area of triangle EBF is 1, and the area of triangle EAD is 9. Find the area of parallelogram ABCD.
Answer:
24
Step-by-step explanation:
If x is an integer, what is the least possible value for x that satisfies the inequality?
-5x - 12 < 33
A. -10
B. -9
C. -8
D. 9
E. 10
Answer:
C. -8
Step-by-step explanation:
We have to solve the inequality by isolating x.
-5x - 12 < 33
Add 12 to both sides.
-5x < 45
Divide both sides by -5 (remember to flip the sign when dividing by a negative).
x > -9
The least possible value for x that satisfies this inequality is -8.
1. 4 < 7 Multiply both sides by 3, then by 2, then by 4, then by 9
2. 11 > -2 Add 3 to both sides, then add 3, then add (-4)
3. -2 < -2 Subtract 6 from both sides, then 8, and then 2
4. -4 < 8 Divide both sides by -4, then by -2
5. Write a short explanation of the effects of the above operations. Did this affect the inequality sign? Was it still true? Why or why not?
Answer:
1. 864 < 1512
2. 12 > 0
3. question 3 is wrong -2 = -2
4. -0.5 < 1
5. In the above operations, they did not effect the inequality sign because the same operation is being done to both sides, therefore the inequality sentences all remained true.
Step-by-step explanation:
1. (3)(4) < (7)(3)
(2)12 < 21(2)
(4)24 < 42(4)
(9)96 < 168(9)
= 864 < 1512
2. 3+11 > -2+3
3+ 13 > 1 + 3
-4+16 > 4-4
= 12 > 0
3. -2 = -2 (question 3 is wrong)
4. -4/-4 < 8/-4
1/-2 > -2/-2
= -0.5 < 1
