Write an equation that is perpendicular to y = 2x + 5 and passes through (3 , -2)

1 answer:

3 0

To find the perpendicular line, we need to find the negative inverse slope.

y = -1/2x - 2

This line also passes through the point since both have the y intercept / value of -2.

Hope this helps!

0.7 (3s + 4)-1.1s = 7.9

vichka [17]

Answer:

s = 5.1

Step-by-step explanation:

$0.7 (3s + 4)-1.1s = 7.9\\$

Multiply both sides of the equation by 10

$0.7\left(3s+4\right)\cdot \:10-1.1s\cdot \:10=7.9\cdot \:10\\\\= 7\left(3s+4\right)-11s=79\\$

Expand

$\mathrm{Expand\:}7\left(3s+4\right)-11s:\\\quad 10s+28$

Subtract 28 from both sides

$10s+28-28=79-28$

Simplify

$10s=51$

Divide both sides of the equation by 10

$\frac{10s}{10}=\frac{51}{10}$

Simplify

$s=\frac{51}{10}\\\\Decimal = 5.1$

Answer:

1. The sum of interior angles of a pentagon is 180 but here the sum of angles of this pentagon is 550 . So it is wrong.

2. Angle 145 is equal to the corresponding of angle y. So angle y is 145 degree.So according to opposite angle theorem, angle x is also 145 degree.

Sorry I do not know next question solutions.
