Answer:

5y = 4x + 10

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

So we change 4x + 5y = 10 to the form in the answer.

What are the x-intercepts of x^2– 3x = 4?

Sindrei [870]

Answer:

x^2-3x=4

x^2-3x-4=0

x^2-4x+x-4=0

x(x-4)+1(x-4)=0

(x+1)(x-4)=0

x=-1,4

x- intercepts in the point (-1,0) and (4,0)

Enter numbers to evaluate ‐13−23.

Nana76 [90]

Answer:

- 13 - 23 = - 13 + (-23)

= -36

- 13 - (- 23) = - 13 + 23

= 10

Step-by-step explanation:

In any order of operation (i.e. addition, subtraction, multiplication, devision) the following rules apply for two values for instance a and b where a > b :

→ If +a and +b then the final sign will be + (positive)

→ If +a and -b then the final sign will be + (positive) since a>b

→ If -a and +b then the final sign will be - (negative) since a>b

→ If -a and -b then the final sign will be - (negative)

In the given question we have two cases.

Case 1:

- 13 - 23 = - 13 + (-23) → since it is given that we add a negative value of -23, therefore it keeps its sign (so this would be a negative addition i.e. adding two negative values)

Thus we have:

- 13 - 23 = - 13 + (-23)

= -36

Case 2:

- 13 - (- 23) = - 13 + 23 → since we stated earlier that - and - gives positive sign (i.e. we subtract two negative values)

Thus we have:

- 13 - (- 23) = - 13 + 23

= 10

So we can see that:

Adding two Negative values gives a Negative value (Case 1)

Subtracting two Negative values gives a Positive value (Case 2)

What is the equation of the line that is perpendicular to y = one-fifth x + 4 and that passes through (5,–4)?

zysi [14]

Answer:

y= -5x + 21

Step-by-step explanation:

The equation of the line that passes through (5, -4) and is perpendicular to line y = 1/5x + 4 is y= -5x + 21

The slope that is perpendicular to the slope 1/5x is -5x.

To find a perpendicular slope, you take the negative reciprocal. (so you change the signs (1/5x is positive so now it would be negative) and -5/1 is basically -5)

However, y = -5x + 4 does NOT pass through (5, -4)

But we still have to write the equation in slope intercept form or the equation of the line

The formula for slope- intercept form is : y= mx + b

So we must plug in (m) which is our -5x and for y we look at the coordinates they gave us ----- (5, -4). -4 is our y. In the coordinates we also have x listed which is 5, so we all plug that in.

y = -5x + b (as you can see -5x is plugged in here)

-4 = -5x + b (as you can see -4 is plugged in here)

4 = -5(5) + b (as you can see 5 is plugged in here)

NOW WE MUST SOLVE!

<h3>Isolate B</h3>

-4 = -25 + b

Add 25 from both sides.

-4 = -25 + b

+25 25

----------------

21 = b

We can now plug this into our slope intercept formula---y= mx+ b---to find the equation of the line.

<h2>Therefore, y = -5 x +21</h2>
