Answer:
-7
Step-by-step explanation:
-4(2)=-8
-8+1=-7........
Y=mx+b is the slope formula
In order to Sherman a line that is either parallel or perpendicular to another line, you first have to put the equation into slope intercept form. This means you have to solve for y.
3x+4y = 7
4y = -3x + 7
y = (-3/4)x + (7/4)
The slope of the line is -3/4. Online which is perpendicular would have a slope of 4/3, The negative reciprocal.
Now that you know the slope, you can write many different equations that would be perpendicular to the original.
y = (3/4)x + any y-intercept....Pick a number, any number... 7. ... y=(3/4)x+7
... -2 ...y = (3/4)x - 2. Literally you can pick any number.
2000 / 4 = 500
500 + 5% = 25
1500 + 1%= 15
Total cash back = 40$
Let x=number
14-5x=3x
5x to other side
14=8x
Divide 8
14/8=x
1 6/8=x
1 3/4=x
1.75=x
