Answer:
y=5/4x-11
Step-by-step explanation:
tenemos un punto (4,-6) y una pendiente equal a 5/4.
usa la ecuación y=mx+b (m es la pendiente, b es el y interceptar)
porque sabemos la pendiente es 5/4, ahora mismo la ecuación es:
y=5/4x+b
en el punto, x=4, y=-6
podemos sustituir los números en la fómula para resolver b
-6=4(5/4)+b
-6=5+b
-11=b
entonces,
la ecuación de la recta es y=5/4x-11
(¡lo siento mi español no es perfecto!)
The equation for the first part would be 4.50p+40=112.
This is because he earns 40 dollars in wages which doesn't change but the number of shoes he commissions, which would be 4.50 per pair. varies based on how many he commissions.
The answer to your second part would be 16.
To find the number, you subtract 40 from each side which gets you 4.50 = 72. From there you just divide which gets you 16.
Another easy way to do it would just be substituting until you find the right number like on a calculator but if you don't have a calculator on hand (let's say for a test), than the first way would be more effective.
Answer:
2472 students
Step-by-step explanation:
<u>What we know:</u>
- There are 6 schools
- Each school has 412 students
<u>What we're trying to solve:</u>
How many students are there altogether?
To find this, we multiply 412 by 6. Doing this is essentially the same as adding 412 to itself 6 times for each school there is in the district.
412 students × 6 schools
= 2472 students
Therefore, there are 2472 students in the district.
I hope this helps!
