Digiron [165]2 years ago
6 0

Answer:

associative

combining

commutative

Step-by-step explanation:

1. <em>associative property of addition</em> since the grouping is changed

2. <em>combining like terms</em> since it's the addition of 4 and 6

3. <em>commutative property of addition</em> since it's a change of order

Write the equation of a line that is perpendicular to y=2/7x +9 and that passes through the point (4,-6).
Allisa [31]

Answer:

y=-\frac{7}{2}x+8

Step-by-step explanation:

Given the equation

y\:=\:\frac{2}{7}x+9

comparing the equation with the slope-intercept form

y =mx+b            

Here,

  • m is the slope
  • y is the intercept

so the slope of the line is 2/7

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so

the slope of the perpendicular line will be: -7/2

Therefore, the point-slope form of the equation of the perpendicular line that goes through (4,-6) is:

y-y_1=m\left(x-x_1\right)

y-\left(-6\right)=\frac{-7}{2}\left(x-4\right)

y+6=\frac{-7}{2}\left(x-4\right)

y+6-6=\frac{-7}{2}\left(x-4\right)-6

y=-\frac{7}{2}x+8

aleksandr82 [10.1K]
The formula is
A=p (1-r)^t
A future value?
P current value 42000
R rate of decreases 0.08
T time 6 years
A=42,000×(1−0.08)^(6)
A=42000 (0.92)^6
A=25,466.91 round your answer to get 25467

Hope it helps!
