First get it into slope intercept form: y=mx+b m is slope and b is the y intercept
-4x-3y=-7
get y by it’s self
-3y=4x-7
divide by -3
y=-4/3x-7/3
so the of the original line is -4/3
the parallel line has the same slope so the parallel slope is -4/3
the perpendicular slope is opposite reciprocal of the original so it is 3/4
Answer:
Step-by-step explanation:
The average number is given by :
[m + (m - 1200) + (m - 1200)(1.30 ] / 3 =
[ 2m + 1.30m - 1200 - 1560] / 3 =
[3.3m - 2760] / 3 =
[1.1 m - 920 ]
Answer:
The correct answer is D) she needs to save 108 more quarters.
Step-by-step explanation:
We know this because the variable is being multiplied by .25, which shows that it is showing a number of quarters.
Answer:
Step-by-step explanation:
Given
--- not more than
spending
Solving (a): Represent as an inequality
Not more than means <
So, the inequality is:
Solving (b): The first two possible solutions
These are the numbers closest to 150 i.e. 149 and 148
Hence,
