Answer:
Step-by-step explanation:
"Four times a number" in symbols is "4n."
Convert all fractions to have the same denominator.
To convert, we must find the least common multiple of the two denominators of the fractions:
Multiples of 4: {4,8,12,16,20}
Multiples of 5: {5,10,15,20}
The least common multiple of 4 and 5 is 20.
Multiply the fractions by a number that will result in the denominator being 20:


The equation should now look like this:

Subtract both sides by 8/20 to get w by itself:


The value of w is 7/20.
Answer:
x-intercept(s) = (-2,0)
y-intercept(s) = (0, - 5/2)
Step-by-step explanation:
the x-intercept, substitute in 0 for y and solve for x
. To find the y-intercept, substitute in 0 for x and solve for y
.
x-intercept(s) = (-2,0)
y-intercept(s) = (0, - 5/2)
