Find three consecutive ODD integers such that the sum of 7 times the smallest and twice the largest is -91. Name the smallest integer..
Answer:
-11, -9, -7the smallest: 2x+1 = -11Step-by-step explanation:
{z - some integer}
2z+1 - the smallest number
7(2z+1) - seven times the smallest number
2z+1+2=2z+3 - the middle number
2z+3+2 = 2z+5 - the largest number
2(2z+5) - twice the largest number
7(2z+1) + 2(2z+5) - the sum of 7 times the smallest and twice the largest
7(2z+1) + 2(2z+5) = -91
14z + 7 + 4z + 10 = -91
-17 -17
18z = -108
÷18 ÷18
z = -6
2z+1 = 2(-6)+1 = -12 + 1 = -11
2z+3 = 2(-6)+3 = -12 + 3 = -9
2z+5 = 2(-6)+5 = -12 + 5 = -7

The sum of two numbers is 82. The larger number is eight less then five times the smaller number. What are the numbers?
Answer:
The smaller Number = 15
The larger number = 67
Step-by-step explanation:
Let
The smaller number = x
The larger number = 5x - 8
The sum = 82
(5x - 8) + x = 82
5x - 8 + x = 82
6x - 8 = 82
Add eight to both sides
6x - 8 + 8 = 82 + 8
6x = 90
Divide both sides by 6
x = 90/6
= 15
Therefore,
The smaller number = x = 15
The larger number = 5x - 8
= 5(15) - 8
= 75 - 8
= 67

14x - 2> 20x + 10
please help!
Answer:
x < -2
Step-by-step explanation:
So if you want to find x we want to simplify the equation first:
14x - 2 > 20x + 10
We should subtract 10 on both sides first:
14x - 12 > 20x
And then subtract 14x from both sides:
- 12 > 6x
Then we want to divide 6 from both sides:
-2 > x
There ya go:
x is less than -2; x < -2

Solve the equation for r. s=7r-33.
Answer: [tex]r=\frac{s+33}{7}[/tex]
Step-by-step explanation:
s = 7r -33. add 33 to both sides +33 -33 =0 ."cancels"
s + 33 = 7r divide both sides by 7 7r/7 7/7 = 1 'cancels' and leaves r
(s + 33) / 7 = r
[tex]r=\frac{s+33}{7}[/tex]
Find the average velocity (in m/s) of a cyclist that starts 200 meters North of town and is 1400 meters North of town after cycling for 20 minutes
Answer:
The average speed is 1 meter per second
Step-by-step explanation:
Here, we want to calculate average speed
Mathematically;
Average speed = Total distance/Total time
In this case, the total distance traveled = 1400-200 = 1,200 meters
Total time taken = 20 minutes
Since 60 seconds = 1 minute; 20 minutes is 20 * 60 = 1200 seconds
So average speed = 1200 meters/1200 seconds = 1 meter/second
solve y/3 +1 = 7/15
Answer:

What is the effect on the graph of f(x)=1/x when it is transformed to g(x)=1/x+9?
A. The graph of f(x) is shifted 9 units up.
B. The graph of f(x) is shifted 9 units to the right.
C. The graph of f(x) is shifted 9 units to the left.
D. The graph of f(x) is shifted 9 units down.
The effect on the graph of f(x) when it transformed to g(x) is the graph of f(x) is shifted 9 units up.
The correct answer is an option (A)
What is function?"It defines a relation between input and output values.""In function, for each input there is exactly one output."What is graph of a function?"It is a set of points which satisfies given function."
For given question,
We have been given two functions [tex]f(x)=\frac{1}{x}[/tex] and [tex]g(x)=\frac{1}{x}+9[/tex]
We know that if function f(x) is transformed to f(x) + k where k > 0, then it translates upward k units.
The function g(x) is f(x) + 9
This means, the graph of function g(x) is the graph of function f(x) shifted 9 units up.
Therefore, the effect on the graph of f(x) when it transformed to g(x) is the graph of f(x) is shifted 9 units up.

The bamboo grows at a rate of 3.75 centimeters per hour.
What is Division?A division is a process of splitting a specific amount into equal parts.
To find the rate at which the bamboo grows, we can use the formula:
rate = distance/time
Here, the distance is 30 centimeters, and the time is 1/3 of a day, which is equivalent to 8 hours. Therefore, we have:
rate = 30 centimeters / 8 hours
Simplifying, we get:
rate = 3.75 centimeters per hour
Therefore, the bamboo grows at a rate of 3.75 centimeters per hour.

Write the equation of the line, in standard form, that has an x-intercept of 2 and is parallel to 2x + y = -5.
Answer:
y = -2x + 2
Step-by-step explanation:
I need the equation of the line, in standard form, that has an x-intercept of 2 and is parallel to 2x + y = -5.
Write the equation of the line, in standard form, that has an x-intercept of 2 and is parallel to 2x + y = -5. Include your work in your final answer.
"parallel"means "same slope".
let's find, first, the slope of the given line: rewrite the equation in standard form,
that is -
y=-2x-0.5
This means the slope of the required line is "-2"
Now, just plugin the numbers into standard equation:
y=slope*x+intercept
you'll end up with
y=-2x+2
