Solve the system of linear equations by graphing
y=1/3x+5
y=2/3x+5
What is the solution
Answers
Answer:
We have the system of equations:
y=1/3x+5
y=2/3x+5
To solve it graphically, we need to graph both lines and see in which point the lines intersect.
You can see the graph below, and you can see that the lines intersect in the point (0, 5)
Now, we can also solve this analytically.
We can use the fact that for the solution, we need y = y.
Then we can write:
(1/3)*x + 5 = (2/3)*x + 5
First, we can subtract 5 in both equations to get:
(1/3)*x = (2/3)*x
This only has a solution when x = 0.
Replacing x = 0 in one of the equations, we get:
y = (1/3)*0 + 5 = 5
Then the solution is x = 0, and y = 5, as we already could see in the graph.

Your grandmother is worried about the heat during the family reunion picnic yesterday between 10 am and noon the temperature rose 6 degrees then between noon and 3pm it rose 4 degrees what was the average rate of increase in temperature between 10am and 3pm
Answers
Answer:
Average rate of temperature increase is 2 degrees per hour
Step-by-step explanation:
Here, we want to calculate the average rate of increase in temperature
From what we have above, we can calculate this by dividing the total temperature rise by the number of hours
The total temperature rise is 6 + 4 = 10 degrees
This means that the temperature rose by 10 degrees between 10 am and 3 pm
The number of hours between 10 am and 3 pm is 5 hours
So the average rate of temperature increase is 10 degrees/ 5 hours = 2 degree per hour

write the equation. the output of a function is 6 more than 2 times the input.
Answers
Answer:
y = 2x+6
Step-by-step explanation:
Let the output value be y
Let the input value be x
the output of a function is 6 more than 2 times the input
2 times the input is expressed as 2x
6 more than 2 times the input is expressed as 2x + 6
Since the output of a function is 6 more than 2 times the input, we will equate y to the resulting equation to have;
y = 2x + 6
Hence the required equation is y = 2x+6

xoxo, your highness...What is the solution to 0.3(12x - 16) = 0.4(12 - 3x)?
Answers
Step-by-step explanation:
The solution is one-solution
.3(12x-16)=.4(12-3x) (you do the distributive property)
3.6x-4.8=4.8-.12x (you add 1.2 to both sides)
3.6x-3.6=4.8 (You add 3.6 to both sides)
3.6x=8.4 ( You divide 3.6 both numbers)
x=0.4285...
Its a one-solution

3 3/4 = r + 1/8
Answers
Answer:
r = 29/8 or 3 5/8
Step-by-step explanation:
so you need to make them have the same denominator so you multiply 3/4 by 2/2 to get that
this equals 6/8
add 3 so 24/8
then you subtract 1/8 from both sides
r = 29/8
simplify so 29/8 = 3 5/8
