Explanation:
The equation y = (2/9)x is in the form y = kx
In this case, k = 2/9.
The value of k is the constant of proportionality.
All direct proportion equations are in the form y = kx. Their graphs go through the origin. The slope of the line is the same as the constant of proportionality.

Solve the inequality.
8+k≤−3
The solution is
.
Answer: k [tex]\leq[/tex] -11
Step-by-step explanation:
8 + k [tex]\leq[/tex] -3 Subtract 8 from both sides
-8 -8
k [tex]\leq[/tex] -11
The solution to the given inequality 8 + k ≤ -3 is k ≤ -11 which represents all values of k that are less than or equal to -11.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
The given inequality is given in the question:
8 + k ≤ -3
To solve the inequality 8 + k ≤ -3, you can start by subtracting 8 from both sides to isolate the variable:
k ≤ -3 - 8
k ≤ -11
The solution to this inequality is all values of k that are less than or equal to -11. This includes all negative numbers less than or equal to -11, as well as -11 itself.
Therefore, the solution to the given inequality is k ≤ -11.

85/1
Step-by-step explanation:
because both numbers are divisible by 16
Answer:
85
Step-by-step explanation:
1360 and 16 both have 16 in common. So...
1,360 ÷ 16 = 85
16 ÷ 16 = 1

Why do scientists use models?
A)
Models are unreliable.
B)
Models waste natural resources.
Models predict not just describe events.
Models are based on scientific laws and principals so they are more
reliable than the real thing.

Step-by-step explanation:
The formula C=5/9(F−32) can be used to convert temperature from Celsius (C) to Fahrenheit (F). The highest temperature ever recorded in the United States was 134 ∘F in Death Valley on July 10, 1913. What was the temperature that day in Celsius, rounded to the nearest degree?
Answer:
57 °C.
Step-by-step explanation:
The formula that is used to convert temperature from Celsius (C) to Fahrenheit (F) is given by :
[tex]C=\dfrac{5}{9}(F-32)[/tex] ...(1)
If T = 134° F, we need to convert the temperature in Celsius.
Put F = 134, in equation (1)
[tex]C=\dfrac{5}{9}(134-32)\\\\=\dfrac{5}{9}\times 102\\\\=56.66^{\circ} C\\\\\text{or}\\\\T=57^{\circ} C[/tex]
So, the temperature on that day is 57 °C.

Find the slope of the line through each pair of points (-17, 11) , (-12, 9) 
Answer:
M = -2/5
Step-by-step explanation:
To find the slope of a line when you know two points, use the following formula.
M = y₂ - y₁ ÷ x₂ - x₁
M = 9 - 11 ÷ -12 - (-17)
M = -2 ÷ 5
M = -2/5

Find x:
[tex]S=\frac{1}{sin2x}+\frac{1}{sin4x}+\frac{1}{sin8x}+...+\frac{1}{sin2^{n}x }[/tex]
Answer:
cotx - cot2ⁿxStep-by-step explanation:
Note: finding the sum not xFirst rewrite the first term as:
1/sin2x = sinx / (sinxsin2x) = sin(2x-x) / (sinxsin2x) =(sin2xcosx - cosxsinx) / (sinxsin2x) = (sin2xcosx)/(sinxsin2x) - (cos2xsinx)/(sinxsin2x) = cosx/sinx - cos2x/sin2x = cotx - cot2xNow the sum is:
S = cotx - cot2x + cot2x - cot4x +... + cot2ⁿ⁻²x - cot2ⁿx =cotx - cot2ⁿx4x - 3y + 9x + (-2) - 10y + 12

At Charles School, 1/5 of the 75 students in seventh grade play in the jazz band. how many seventh graders play in the jazz band?
Answer:
15
Explanation
1/5x75=75/5 =15
15 seventh graders play in the jazz band as per the given ratio.
What is the ratio?One quantity can be expressed as a fraction of other quantities using a ratio, which is a number. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
Given At Charles School, 1/5 of the 75 students in seventh-grade play in the jazz band.
In the form of a ratio
1/5 the students out of 75 play in the jazz band
Total students play in the jazz band = 75* 1/5
Total students play in the jazz band = 15

A cheetah's speed was timed overa
100-yard distance. The cheetah was
(PLEASE HELP ME)clocked running 70 miles per hour. Which
equation shows the relationship between
the distance, y, and time, x, the cheetah
runs?
Answer:
y = 70x
Step-by-step explanation:
Note that d = rt where d is the distance, r is the rate/speed, and t is the time. Since we are given that the variable x is the time, 70mph is the speed, and the variable y is the distance, we can substitute these into d = rt, which we get y = 70x.

On Monday Matty worked for 450 minuites in his office on Tuesday he worked half the numbers of minute he worked on Monday on wends day he worked only 1/2 day Wichita was 300 minute how many more minutes did he work on wensday then thursday
Answer:
The answer is 75 minutes.
Explanation :
Wednesday is 300 minutes & Tuesday is 225 minutes because 450 ÷ 2 = 225.
Wednesday is 300 minutes & Tuesday is 225 minutes because 450 ÷ 2 = 225. SO 300 - 225 = 75.
CAN YOU PLS GIVE ME BRAINLIST? THANK YOU! :))
Answer:
He worked for 75 more minutes on Wednesday then on Tuesday.
Step-by-step explanation:
So since we know that Matty worked for 450 minutes in his office on Monday, we can find out for how long he was working on Tuesday since we know that.......
Let "y" be the number of minutes Matty will work on Tuesday
Let "x" be the number of minutes Matty worked on Monday
[tex]y = \frac{x}{2}[/tex]
Substitute the values we have and get......
[tex]y = \frac{450}{2}[/tex]
[tex]y = 225[/tex]
So now we can find out how much more he worked on Wednesday then on Tuesday by doing the following......
Let "w" be the number of minutes Matty worked on Wednesday, then.......
The answer = [tex]w - y[/tex]
The answer = 300 - 225
The answer = 75
