Veronica tried to solve an equation step by step.

No steps are wrong. To solve this equation, you need to isolate the y. So, you would add 4.6 to both sides to cancel out the 4.6 on the right side and isolate the y.

What is the meaning of the variable x in terms of 2.25+0.5x=3.75?

Eddi Din [679]

You have to do 3.75-2.25=1.5 then 1.5/0.5 which means that x=3.

Answer:

m=0.5 b=1

Step-by-step explanation:

M is the increase in value by one square point via b.

B is the y axis beginning position.

I could be wrong, though.

If f(x) is a linear function, what is the value of n? x f(x) –4 –25 –1 –10 n 20

12345 [234]

Answer:

The value of n is 5.

Step-by-step explanation:

We have been given that f(x) is a linear function and we are asked to find the value of n from the provided table.

x f(x)

-4 -25

-1 -10

n 20

First of all we will find the slope of the given using our given points (-4,-25) and (-1,-10) in slope formula.

$m=\frac{y_2-y_1}{x_2-x_1}$

Upon substituting coordinates of our given points we will get,

$m=\frac{-10--25}{-1--4}$

$m=\frac{-10+25}{-1+4}$

$m=\frac{15}{3}$

$m=5$

Since we know that the equation of a line in slope-intercept form is: $y=mx+b$ , where, m= Slope and b= y-intercept.

Upon substituting m = 5 in slope-intercept form of equation we will get,

$y=5x+b$

Now let us find y-intercept by substituting coordinates of one point in our given line.

$-10=5(-1)+b$

$-10=-5+b$

$-10+5=-5+5+b$

$-5=b$

So the equation of given line will be,

$y=5x-5$

Now let us find value of n by substituting x = n and y = 20 in our equation.

$20=5*n-5$

$20+5=5*n-5+5$

$25=5*n$

$\frac{25}{5}=\frac{5*n}{5}$

$5=n$

Therefore, the value of n is 5.
