What is the slope of the line perpendicular to the line with equation 4x-5y+13=0
motikmotik

Answer:

m = - 5/4

Step-by-step explanation:

If two lines are perpendicular, their slopes are negative reciprocals, which means that their product is -1

We can write the equation

4*x - 5*y + 13  = 0

as:      5*y  =  4*x  + 13      or    

y  = (4/5)*x  + 13        (1)

Equation (1) is the equation of a straight line in its slope point form, 4/5 is the slope, according to this  the slope of a perpendicular line is

-5/4

Irina-Kira [14]

Answer: x=-1

Step-by-step explanation:

the x value of the vertex = -b/2a if the equation is in "ax^2+bx+c" for

you are in luck

x value of the vertex = -4/4 = -1

the line of symmetry is a vertical line, and since it must pass through the vertex

line of symmetry: x=-1

2x+5y=-21 , -2x+3y+-27
Elis [28]

Answer:

x=4.5 and y=  -6

Step-by-step explanation:

2x+5y= -21

-2x+3y= -27

add the two equations: 8y= -48

y=-48/8= -6

sub for y in 2x+5y= -21

2x + 5(-6)=-21, 2x-30= -21

2x= -21+30= 9

x= 9/2=4.5

Maxwell is taking out a loan for $8,750 for 2 years at an APR of 9.75%. What would be the finance charge to the nearest whole do
Sladkaya [172]

Answer:

Step-by-step explanation:

Using the formula for calculating simple interest

SI = principal × rate × time/100

Given

Principal = $8750

Rate = 9.75%

Time = 2years

Substitute

Interest = 8750×9.75×2/100

Interest = 87.59×19.5

Interest = 1,706.25

Hence the finance charge to the nearest whole dollar is $1706
