Write the slope-intercept form of the equation through (-5, -4) perpendicular to y=5x+1

Mathematics
1 answer:
inna [77]3 years ago
8 0

Answer:

Ah! This brings me back to Coordinate Geometry!

Step-by-step explanation:

First, we need to find the slope of our line. We can't do this using the single point we are given, so we are going to have to use the other line for reference.

Now, if you did not know, the equation to find the slope of one line perpendicular to another line is:

m_{1} =-\frac{1}{m_{2} }

Where m1 is the slope of one line, and m2 is the slope of the other.

So, we input it!

m_{1} =-\frac{1}{5}

See? Easy! (m1 is the slope of the line we are trying to find)

Thus,

y=-\frac{1}{5}x+b\\

Gotta go!

Then we input the point into this equation to find the y-intercept!

Thus,

y=-\frac{1}{5}x+b\\\\-4=1+b\\-5=b

So there's your line: y=-\frac{1}{5} x-5

Hope this helps!

Gotta Go!

P.S. Stay Safe!

The model of a trinomial is shown.
galben [10]

The factors of the trinomial based on the information given include:

C. x – 7

E. x + 2

<h3>What is a trinomial?</h3>

It should be noted that a trinomial is an algebraic expression that has three non-zero terms. Here, the examples of a trinomial expression: x + y + z is a trinomial in three variables x, y and z. Also, 2a² + 5a + 7 is a trinomial in one variables.

In this case, the algebra tile configuration has 0 tiles are in the Factor 1 spot and 0 tiles are in the Factor 2 spot. 24 tiles are in the Product spot: 1 is labeled + x squared, 7 are labeled negative x. Here, the trinomial is x² - 5x - 14.

The factors will be:

x² - 5x - 14.

x² + 2x - 7x - 14

x(x + 2) - 7(x + 2)

= (x + 2)(x - 7)

A polynomial with three terms is called a trinomial.

In conclusion, the correct options are C and E.

Does anyone know how to do this ??
Mashcka [7]
2(3 exponent 2) + 4(3)(5) follow my equation and you should get your answer. all you have to do is replace the letters in the formula in the needed numbers. For instance s= 3 and h=5 , therefore you replace the s in the formula to a 3 and the h in the formula to a 5

Tavon has a $50 gift card that loses $2 for each 30-day period it is not used. He also has a $40 gift card that loses $1.50 for
svp [43]

Answer:

20

Step-by-step explanation:

The first equation is 50 - 2x (because you start with $50 and subtract 2 for each 30 day period)

 

The second equation is 40-1.5x

 

Set them equal to each other:  50 - 2x = 40 - 1.5x

Solve for x:

 

50 - 2x = 40 - 1.5 x

    +2x         +2x

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

 

50 = 40 + 0.5 x

-40   -40

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

10 = 0.5 x

20 = x

 

So there will be 20 30-day periods until the cards will be equal in value.

 

Check:  After 20 periods, 50 - 2(20) = $10 left

 

40 - 1.5(20) = also $10 left
