Determine the ratio of defective telephones
ratio = 9/30
ratio = 3/10
3 of 10 telephones are defective
Determine the number of defective telephones each day
def telephone = ratio of defective × total production
def telephone = 3/10 × 1000
def telephone = 300
There are 300 defective telephones each day
Answer:
-21/5 or -4.2
Step-by-step explanation:
y = 2x + 6
3y - x + 3 = 0
Substitute the value for y from the first equation into the second equation. Solve for x.
3y - x + 3 = 0
3(2x + 6) - x + 3= 0
6x + 18 - x + 3 = 0
5x + 18 + 3 = 0
5x + 21 = 0
5x + 21 - 21 = 0 - 21
5x = -21
x = -21/5 or -4.2
Answer:
y = 4x - 9
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
rearrange y - 4x = - 9 into this form
add 4x to both sides
y = 4x - 9 ← in slope-intercept form
The answer would be log62...
