Answer:
The coordinates of the science lab is:
x = -14/3 , y = 1
Step-by-step explanation:
∵ P is (-8 , -1) and Q is (2 , 5)
∵ The point of the science lab is (x , y)
∵ The science lab point divided PQ at ratio 2 : 1 from Q (two thirds PQ)
∴ 
∴ 
∴ 
∴ 
∴ The point of science lab = (-14/3 , 1)
Answer:
x = 91/11
Step-by-step explanation:
1. x - 3/11 = 8
2. add 3/11 to both sides of the equation
3. x = 91/11
The answer is 248!grains I think this one I think is easy
Using linear equations, the number of minutes that both would read for them to read equal number of pages is: 30 minutes.
<h3>What is the Equation of a Linear Graph?</h3>
Equation of a linear graph is given as, y = mx + b, where m and b are the slope and y-intercept of the graph respectively.
Equation for Emily's graph:
Slope (m) = rise/run = 1/3
y-intercept (b) = 2
Substitute m = 1/3 and b = 2 into y = mx + b
y = 1/3x + 2
Equation for Serena's graph:
Slope (m) = rise/run = 2/5
y-intercept (b) = 0
Substitute m = 2/5 and b = 0 into y = mx + b
y = 2/5x + 0
y = 2/5x
To find how many minutes for both of them to read the same number of pages, make both equations equal to each other.
2/5x = 1/3x + 2
2/5x - 1/3x = 2
1/15x = 2
Multiply both sides by 15
x = (2)(15)
x = 30
The answer is 30 minutes for both to read the same number of pages.

Answer:
(4y/3, 0) or if there are no options, it's probably (0, 0)
Step-by-step explanation:
2x + 3y = 5x - y
So we are trying to find the missing value in the solution (_, 0)
We are looking for the x-intercept/root if the coordinate is in this way: (_, 0)
So to find the root, We are solving for x
2x + 3y = 5x - y
First, subtract 5x from bth sides
2x + 3y - 5x = 5x - y - 5x
2x + 3y - 5x = -y
Add like terms
-3x + 3y = -y
Now, subtract 3y from both sides
-3x + 3y - 3y = -y - 3y
-3x = -4y
Divide both sides by -3
-3x/-3 = -4y/-3
x = -4y/-3
We are not done yet because the answer above is not quite right. A negative number divided by a negative number results in a positive number.
So x = 4y/3
Now that we found x, we can input it to the coordinate
(4y/3, 0)
I put it on Sesmos graphing calculator and the answer seems to be (0, 0)
