You can isolate y and you know that the slope is the number in front of x (the one that multiplies it)
You know that the y-intercept is the value of y when x=0, therefore you can find y by replacing x with 0 in the equation
1-equation
5x-8y=3
5x=3+8y
5x-3=8y
(5x-3)/8=y
y=(5/8)x -3/8
(Slope = 5/8)
2- y-intecept (x=0)
y=(5/8)(0)-3/8
y=-3/8
let y be the horizontal distance and x the vertical
y/400 = cos 20
y=400 cos20
y=376m
x/400 =sin20
x=400sin20
x=137m
Question:
Three students were working on 630,000÷700 in math class.
a. Desiree finds the quotient is 9,000 and Micah finds the quotient is 900.
Determine which student found the correct quotient.
b. Delilah finds her answer is 90, but she copied the expression incorrectly from the board. If her reasoning and answer for the expression she copied are correct, what expression might she have written?
Answer:
a. Micah is correct
b.


Step-by-step explanation:
Given



Solving (a): Who is correct?
To do this, we first calculate the quotient of the expression.

Divide 630000 by 700

Hence:
Micah is correct
Solving (b): What Delilah must have copied?
We have:

There are no options to pick from. So, we just need to work out expressions that equals 0.
Possible expressions are:


Factored form:
(x-8)(x-5)
Proof:
-8-5=-13
-8*-5=40
Final answer: A
Xm-2m
(-2)(-3)-2(-3)
12
The equation can be simplified to 12. I'm not sure how you got 0, but at a guess, you messed up your signs when multiplying. Hope this helps!
