Solve for y 2/5x + y = 3
Answer:
y=-2/5x +3
Step-by-step explanation:
You get the y to be alone on it's side of the equal sign.
So you subtract 2/5 x from that side and what you do to one side you have to do to the other.
You get: y=-2/5x +3
Two expressions with equal sign is Equation. y= 3-2/5x is the solution for y if equation is 2/5x + y = 3.
What is Equation?Two expressions with equal sign is called as Equations.
Given Equation is 2/5x + y = 3, we need to solve for y.
You get the y to be alone on it's side of the equal sign.
So you subtract 2/5 x from that side and what you do to one side you have to do to the other.
2/5x + y = 3
y = 3-2/5x
Therefore y=3-2/5x is the solution for 2/5x + y = 3 equation.

1. Two students conducted similar experiments. The results of their experiments are
very different. What is the best step for the students to take next?
A. Change the experiment that is not correct.
B. Determine that both students are in correct.
C. Assume that both students' results are reliable,
D. Replicate the experiment to see whose results are more reliable.
Answer: D. Replicate the experiment to see whose results are more reliable.
Step-by-step explanation:
The experiments are similar, then we should expect to see similar results.
Now, we know that they get different results, let's analyze the options:
A) With the given information we can not conclude which is the incorrect experiment, then this is discarded.
B) We can not really determine that both students are in correct only knowing the experiment and the results, so this is also discarded.
C) You can not assume things.
D) This is the correct option, an experiment must be repeatable. This means that, with the same conditions, the result must be always the same.
Then we can replicate both experiments and see if the results are the same as before to determine if the results are reliable.

What is Equation of line?The equation of line in point-slope form passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is,
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (- 1, 0) and (0, 1).
Now,
Since, The equation of line passes through the points (- 1, 0) and (0, 1).
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (1 - 0) / (0 - (-1))
m = 1 / 1
m = 1
Thus, The slope of the line in the graph is,
⇒ m = 1

Write rate as a untit rate for240 miles in 6 hrs
Answer:
40 mph or 40 miles per hour
Step-by-step explanation:
If there is 240 miles in 6 hours, so you can divide the 240 by 6 to get the unit rate of miles per hour.
240 divided by 6 is 40
Answer: 240 miles in 6 hours as a unit rate would be 240 over 6. This is because with unit rates to find how many miles in one hour you would divide 240 by 6. (This would give you 40.)

The functions f(x) and g(x) are described below.
f(x) = 7x + 9
g(x) = 7x - 4
The graph of g(x) is obtained by shifting down the graph of f(x) by _____ units.
Answer:
13 units
Step-by-step explanation:
Because the c term (9 for f(x)) represents the y intercept. The y only moves the graph up or down. Since we are trying to get from 9 to -4 move down by 13 units.
What is the equation of a line that is parallel to y=4 that passes through (1, -5)
Answer:
y = - 5
Step-by-step explanation:
y = 4 is a horizontal line parallel to the x- axis
A parallel line must therefore be a horizontal line with equation
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (1, - 5) with y- coordinate - 5, thus
y = - 5 ← equation of parallel line

Step-by-step explanation:
If you divide the fractions to decimals 1/6 equals .16 which is closest to 0
Answer:
to acuratly measure the value of each fraction to determine which fraction is closest to 0 we need to get a common denom:
1/6---->2/12
11/12
5/6---->10/12
10/12
Now that we hahve a common denom we just need to find the smallest numerator value of these fractions.

which line is perpendicular to y=2x+4?
a. y=2x-6
b. y=-1/2x+7
c. y=-1/4x+2
d. y=-4x+3
Answer:
B
In the equation y=mx+b m is the slope of the line.
Therefore the coefficient in each of these equations is the slope.
A line with a perpendicular slope must have the inverse opposite of the actual line. For example if a line has a slope of 5, a perpendicular line to that line must have a slope of -1/5. If a line has a slope of 10, the perpendicular line has a slope of -1/10. If a line has a slope of 2 then the inverse opposite is -1/2 and that is the slope of the perpendicular line.
B is the only answer with the correct slope so B is the answer.

showed a profit of $5000. Assuming the profitloss is linear, write the equation of the line, in slope-intercept form, that represents the profit/loss for each month x. Use
this result to predict the profit/loss after 60 months
Hint: Use the ordered pairs (5. - 3) and (25,5).

(Type an equation using x and y as the variable. Type your answer in slope-intercept form. Use integers or fractions for any numbers in the equation.)
..There would be a of safter 60 months
Answer:
Step-by-step explanation: slope is (9-(-3))/(25-5)

A random sample of online music video views and number of guitar sales was measured, and the computer output for regression was obtained: Coefficients Standard Error t Stat P-value Intercept 7.856710924 1.316226455 5.969118 0.001889 Music Video Views 0.094781123 0.027926367 3.393965 0.019378 R-sq. = 69.73%R-sq. (adj) = 63.68% Part A: Use the computer output to determine the LSRL. Identify all the variables used in the equation. Part B: What proportion of the variation of guitar sales is explained by its linear relationship to music video views? Explain. Part C: Determine if increased guitar sales were caused by online music video views. Explain your reasoning.
Answer:
Explained below.
Step-by-step explanation:
The regression analysis output is as follows:
Coefficients Standard Error t Stat P-value
Intercept 7.856710924 1.316226455 5.969118 0.001889
Music Video 0.094781123 0.027926367 3.393965 0.019378
Views
R-sq. = 69.73%
R-sq. (adj) = 63.68%
A
There are two variables used in this study, the independent and the dependent variable.
The independent variable is the number of online music video views and the dependent variable is the number of guitar sales.
B
The coefficient of determination R² specifies the percentage of the variation in the dependent variable (Y) that is forecasted or explained by linear regression and the forecaster variable (X, also recognized as the independent-variable).
Thus, the proportion of the variation of guitar sales that is explained by its linear relationship to music video views is 69.73%.
C
The least square regression line is:
[tex]y=7.856710924+0.094781123\cdot x[/tex]
The least square regression line implies that there is a positive relationship between the guitar sales and music video views. That is as the number of music video views increases the guitar sales increases. And vice-versa.
Thus, increased guitar sales were caused by online music video views.
