$(2a + 4b)/(2b) = 3.9 \n (a)/(b) = what$
with full explanation please

Answers

Answer 1

Answer:

Answer: 1.9

Work Shown:

$(2a+4b)/(2b) = 3.9\n\n(2a)/(2b)+(4b)/(2b) = 3.9\n\n(a)/(b)+2 = 3.9\n\n(a)/(b) = 3.9-2\n\n(a)/(b) = 1.9\n\n$

Select the equation of the line that passes through the point (5, 7) and is perpendicular to the line x = 4.y = 4
x = 5
y = 7
x = 7

Answers

Answer:

y = 7

Step-by-step explanation:

x=4 is a vertical line that goes through the point x=4. y value of this graph changes while x value will be 4 at every point of the graph.

A line perpendicular to this will be a horizontal line with a fixed y value and the x value will change.

The coordinates of the point of which the line has to pass is given as (5,7). Which means the y coordinate of this line is 7.

As we have established that this line has to have same y value at each point just like x=4 has same x value at each point, we can say the equation of the line is y=7.

Solution:

Equation of line perpendicular to , x=4 is

y +k=0

As, keep in mind , the equation of line perpendicular to , ax + by +c=0 is b x - a y +c=0

As, given the line perpendicular to, x =4, passes through the point (5,7).

So, y+k =0, passes through (5,7).

→ 7 +k=0

→ k= -7

So, line perpendicular to x=4, which passes through the point (5,7) is →y-7=0 that is y=7.

Option (C) →y=7

What are some differences and similarities between a trapezoid and a square?

Answers

The difference between a square and a trapezoid is that first a square has equal sides while trapezoid does not have. The angles inside the square are perpendicular while trapezoid has not. A trapezoid also has one pair of non-parallel sides.

They both have 4 sides and 4 angles.
Trapezoid has 4 different length & angles, square has all same length and angles.
