If you would like to solve the equation 4/5 * x = 2/5, you can calculate this using the following steps:
4/5 * x = 2/5 /*5
4 * x = 2 /4
x = 2/4
x = 1/2
The correct result would be 1/2.
Answer:
K would equal to:
K= 50
Hope that helps! :)
Step-by-step explanation:
Answer: y= 3x-1
Step-by-step explanation:
Equation of a straight line:
y = mx + b ------(i)
Step by Step Solution:
Step 1: Calculating Slope (m).
m =
y2-y1
x2-x1
m =
2--1
1-0
m =
3
1
m = 3
Now putting value of m in equation (i)
y = 3x + b -----(ii)
Step 2: Calculating Y-intercept (b).
Lets choose the first point, (0,-1) for calculating y-intercept:
y = mx + b
-1 = 3(0) + b
-1 = 0 + b
-1 = b
b = -1
Problem 1: Plug in the given value into the function and evaluate.

Problem 2: Solve the equation for y.

add 7x to both sides to move it to the right side of the equation.

Divide both sides of the equation by 2 to get a single y variable on the left hand side.

Simplify the terms to get the the equation into slope-intercept form.
The slope of the line is 
I'm a unsure what Problem 3 is asking for sorry I hope the rest is helpful.
