11. Find the slope of the line that passes through
the points (-1, -3) and (-9, 7).
Answer:
y=-2/11x-7/11
Step-by-step explanation:
Answer:
[tex](-10,8)[/tex] or [tex]\frac{-10}{8}[/tex]
Step-by-step explanation:
In order to find the answer to this question you must put the coordinates into the slope formula and solve.
[tex]slope=\frac{y^2-y^1}{x^2-x^1}[/tex]
[tex](x^1,x^2)=(-1,-9)[/tex]
[tex](y^2-y^1)=(-3,7)[/tex]
Substitute:
[tex]\frac{-3-7}{-1--9}[/tex]
Solve using KCC:
[tex]-3-7=-3+-7=-10[/tex]
[tex]-1--9=-1+9=8[/tex]
[tex]slope=(-10,8)[/tex]
Hope this helps.

What is the solution to the inequality 7x - 26>3 (3x-2)
Answer:
the solution to the inequality is x<-10
Answer:
x<−10
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
7x−26>9x−6
Step 2: Subtract 9x from both sides.
7x−26−9x>9x−6−9x
−2x−26>−6
Step 3: Add 26 to both sides.
−2x−26+26>−6+26
−2x>20
Step 4: Divide both sides by -2.
-2x/-2 > 20/-2
x<−10

in 2016 5200 parking permits were issued in a city the number of parking permits increased by 5% every year but y represent the number of parking permits issued X years since 2016
A) the situation represents an arithmetic sequence because the successive y-values have a common difference of 1.05.
B) the situation represents a geometric sequence because the successive y values have a common ratio of 1.5.
C) the situation represents a geometric sequence because the successive y values have a common ratio of 1.05.
D) the situation represents an arithmetic sequence because of the successive y values have a common difference of 1.5.
Answer:
C) the situation represents a geometric sequence because the successive y values have a common ratio of 1.05.Step-by-step explanation:
Initial number is 5200
Every year the number increases by 5%
It can be represented as:
y = 5200*(1 + 0.05)^x = 5200*1.05^x, this is a GP with common ratio of 1.05Correct choice is C

Mr. Fowler's science class grew two different varieties of
plants as part of an experiment. When the plant samples
were fully grown, they compared their heights.
Pls help
Option D is the correct option.
What is Mean Absolute Deviation?'The mean absolute deviation (MAD) is the mean (average) distance between each data value and the mean of the data set.'
According to the given problem,
The mean height Variety A = 19 [ from the table ]
The mean height of variety B = 13 [ from the table ]
The spread is given by the mean absolute deviation, which 1.2 for Variety A and 2.4 for Variety B. So we can see that, the spread in Variety A is lesser than the spread in Variety B, which shows that the average height of Variety A varies less than the average height of Variety B.
We can see from the table that the average height of a variety A is indeed greater than that of Variety B. Also we can see that the Mean Absolute deviation of Variety A is 1.2 which is lesser than the Mean Absolute deviation of Variety B.
Hence, option D is correct since the average height of Variety A is greater than Variety B, and also the mean varies lesser in Variety A than in Variety B.

How do i find the slope of this line?
Answer:
slope is 1
Step-by-step explanation:
rise / run = 5 / 5
the slope is 1
Answer: Well I can tell you that your answer is right, the answer is one.
Step-by-step explanation:
Pick two points on the line and determine their coordinates.
Determine the difference in y-coordinates of these two points (rise).
Determine the difference in x-coordinates for these two points (run).
Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).

1) x < -14
please help i don’t know how to do this
Answer: See the diagram below.
This diagram shows a closed filled in circle at -14 on the number line. Also, the shaded region is to the left of the closed circle. This visually represents values that are smaller than -14, or equal to -14.
The filled in circle is used to indicate "include this endpoint". In contrast, an open hole indicates "do not include this endpoint" which is only used if the inequality was [tex]x < -14[/tex] instead of [tex]x \le -14[/tex]. The "or equal to" portion is why we include the endpoint.

finding x - cicrle theorems
Answer:
x = 30
Step-by-step explanation:
AB is a tangent to the circle so ∠ ABO = 90°
The sum of the 3 angles in a triangle = 180° , then
x + 2x + 90 = 180
3x + 90 = 180 ( subtract 90 from both sides )
3x = 90 ( divide both sides by 3 )
x = 30
Answer: x = 30
OA cuts the circle (O) at C
because ∠ABC is the angle created by tangent rays and chord
=> ∠ABC = 1/2.∠AOB = 1/2.2x = x
ΔOBC has OB = OC (are both radii)
=> ΔOBC is the isosceles triangle at O
=> ∠OCB = (180° - ∠COB)/2 = (180° - 2x)/2 = 90° - x
because ∠OCB is the outer angle of ΔABC
=> ∠OCB = ∠ABC + ∠CAB
⇔ 90° - x = x + x
⇔ 90 = 3x
⇔ x = 30
