Find the value of x

Answer:

y = -(5/2)x + 3 is a line perpendicular to y = (2/5)x + 2. This line is also perpendicular to y = (2/5)x + 9 because it has the same slope.

Step-by-step explanation:

A) So the line you are given is written in slope intercept form y = mx + b meaning that the slope of the line is  m = 2/5 and the intercept  b = 9 (so the line hits the y axis at 0,9). A line that is parallel has to have the same  slope so we know our m is the same. So we have y = (2/5)x + b. We need b. It passes (0, 2) since the x coordinate is 0 you know the y intercept is 2 but you can verify this using the point slope formula:

y - y1 = m(x - x1) plug in values

y - 2 = (2/5)(x - 0) now simplify

y - 2 = (2.5)x  last solve

y = (2/5)x + 2 see how when the x coordinate is 0 you can automatically use the point slope intercept formula? Neato!

B) Now we want a line perpendicular to y = (2/5)x + 2 and that passes through 0,3. What are the properties of a line perpendicular to a line of the form y = mx + b and passes through (0, 3)?  We know that the slope of this new line will be the reciprocal and have the opposite sign of m. So the new slope we will call it mnew = -(1/m) so plug in for m and you get mnew = -(1/[2/5]) if you simplify you get that the mnew = -(5/2). So we have half of our equation for the perpendicular: y = -(5/2)x + b. If you look at (0, 3) you see that the y intercept is 3 so b = 3. So:

The equation of the line that passes through given point and is parallel to the line with the given is y = 2x-1

An equation is a mathematical statement that shows that two mathematical expressions are equal.

Given that, we need to find the equation of a line passing through the point (3, 5) and is parallel to y = 2x-6,

Comparing the given equation with the general equation of line y = mx+c

m = 2 (the slope)

We know that the two parallel lines have equal slope.

Therefore, the required equation is =

y = 2x+c

To find the value of c, put x = 3 and y = 5,

5 = 2(3) + c

c = -1

Therefore,

The required equation is =

y = 2x-1

Hence, the equation of the line that passes through given point and is parallel to the line with the given is y = 2x-1

Answer:

[tex]\frac{A-2wh}{2(w+h)}=l[/tex]

Step-by-step explanation:

We have to find the formula for the value of 'l'.

So, we will isolate 'l' on one side of the formula.

A = 2lw + 2lh + 2wh

A = 2l(w + h) + 2wh

A - 2wh = 2l(w + h) + 2wh - 2wh

A - 2wh = 2l(w + h)

[tex]\frac{A-2wh}{2(w+h)}=\frac{2l(w+h)}{2(w+h)}[/tex]

[tex]\frac{A-2wh}{2(w+h)}=l[/tex]

Therefore, formula for 'l' will be,

[tex]\frac{A-2wh}{2(w+h)}=l[/tex]

Answer:

[tex]x=\frac{20}{3} =6.67[/tex]

Step-by-step explanation:

[tex]x=15*\frac{4}{9}=\frac{20}{3} =6.67[/tex]

Answer:

6 2/3 or 20/3 or 6.6667

Step-by-step explanation:

Since the figures are similar, you can find x through comparing ratios. To get from 9 to 4, multiply 9 by 4/9. To find x, you must then multiply 15 by 4/9.

15 x 4/9 = 6 2/3 or 20/3 or 6.6667

Answer:

Since there are two angles which are equal in the triangle we can make our equation as-

2x+60=180

(180 cuz the sum of all angles in a triangle will ALWAYS be 180)

so if we solve,

2x=120

x=120/2

x=60

thus x=60

Answer

60

Explanation:

So a given shape will always have a degree of 180.

We know one of the degrees is 60, so we can subtract that to find the missing degree angles: 180 - 60 = 120

We can divide 120 by 2 to spilt that into two degrees: 120 ➗ 2 = 60

(If you have math sense, you can tell that they all have the same angle, so same angle means same degree)
