The first number is 7 greater than a second number. Twice the first number is 4 more than three times the second. Find the two numbers.
Answers
Step-by-step explanation and answer:
Setting up a system of equations would be the easiest method for this question. The first number will be x. The second number will be y. According to the question:
x+1=y
2x-4=5y
Since the first equation is already solved for y, you can plug the whole first equation in for y in the second equation, then solve for x.
2x-4=5(x+1) Distribute the 5
2x-4=5x+5 Subtract 5x from 2x
-3x-4=5 Subtract -4 from 5 (add 4 to 5)
-3x=9 Divide to get the x by itself
-3=x
Now that you have x solved for, you can plug it into the first equation (or second, if you prefer) to solve for y.
x+1=y
-3+1=y
-2=y
An astronomer knows that a satellite orbits the Earth in a period that is an exact multiple of 1 hour that is less than 1 day. If the astronomer notes that the satellite completes 11 orbits in an interval that starts when a 24-hour clock reads 0 hours and ends the clock reads 17 hours, how long is the orbital period of the satellite?
Answers
Answer: The Satellites Orbits the Earth every 19 hours!
Step-by-step explanation:
Okay, I went to go re-searching for this question hopefully this helps love, from below! You should write this down, so it's easier for you to remember.
The total orbital period of the satellite is 1.54 hours and this can be determined by using the given data.
Given :
An astronomer knows that a satellite orbits the Earth in a period that is an exact multiple of 1 hour that is less than 1 day.The astronomer notes that the satellite completes 11 orbits in an interval that starts when a 24-hour clock reads 0 hours and ends the clock reads 17 hours.The following steps can be used in order to determine the total orbital period of the satellite:
Step 1 - Let the number of hours to complete one orbit be 'x'.
Step 2 - According to the given data, the astronomer notes that the satellite completes 11 orbits in an interval that starts when a 24-hour clock reads 0 hours and ends the clock reads 17 hours.
Step 3 - So, the linear equation that represents the given situation is:
11x = 17
x = 17/11
x = 1.54 hours

Answer:
Read below for each answer! (^-^)
Step-by-step explanation:
1: You got the first one right. The explanation does explain why but think about 0 as the surface of the water to better understand.
2: -3; it is between 2 and 4 with only one line through it meaning that it is -3.
3: 7. That's the greatest number both can divide into it.
4: The last one. Any positive number is greater than a negative one and peanut butter's freezing point is positive while the other one's is not.
5: You got it right again! -(-1) has two negatives. Two negatives (mostly) make a positive. So positive 1! Now describe that on a number line.

Answers
Answer:
0 ,1,2,3,/ is range/ y is the independent varibal/ x is the dependent varible/ /the equation is the domain
Step-by-step explanation:
The domain and independent variables are 0, 1, 2, and 3.
The range and dependent variables are 8, 10, 12, and 14.
What is a function?A function is defined as a relation between a set of inputs having one output each.
Inputs are called the domain and independent variables.
Outputs are called the range and dependent variables.
We have,
y = 2x + 8
y = cost of pizza in dollar
x = toppings on pizza
x = 0, 1, 2, or 3
y = 2 x 0 + 8 = 8
y = 2 x 1 + 8 = 2 + 8 = 10
y = 2 x 2 + 8 = 4 + 8 = 12
y = 2 x 3 + 8 = 6 + 8 = 14
Thus,
The domain and independent variables are 0, 1, 2, and 3.
The range and dependent variables are 8, 10, 12, and 14.

Given that the equation y=mx + b where m is 12 and the line passes through the point (-2,8), what would be the value of b?
a. b = -16
b. b = -8
c. b = 16
d. b = 32
Answers
Answer:
d
Step-by-step explanation:
The answer would be D. We can continue the line from the point (-2,8) because we know the slope so we will continue it forward by two on the x axis. Since we go forward by two we are going up by 24 (12*2) on the y axis so the y intercept (b) would be 8 + 24 which is 32. Sorry if it is hard to understand.

Plzzzz help ASAP. What is an equation of the line that passes through the point (1,6) and is perpendicular to the line x+3y=27
Answers
Answer:
y = 3x + 3
Step-by-step explanation:
x + 3y = 27
3y = -x + 27
y = [tex]\frac{-1}{3}x +\frac{27}{3}[/tex]
y = [tex]\frac{-1}{3}x + 9[/tex]
m₁ = -1/3
the slope of the line perpendicular to x + 3y = 27 is m₂ = -1/m₁
m₂ = [tex]-1 * \frac{-3}{1}[/tex] = 3 , Point (1 , 6)
y - y1 = m (x -x1)
y -6 = 3(x - 1)
y - 6= 3x - 3
y = 3x - 3 +6
y = 3x + 3
Answer:
3x-y=27
Step-by-step explanation:
perpendicular is making a 90 degree angle, so it would need to be a slope of 3 if the other is -1/3.
y=9, x=27
3x-y=27 is the polar opposite, and should work, sorry if wrong. hard to do in my head without a graph to help.
