Solve for a. Show your work (ALL steps must be shown): 3(a+3)+6=30

Answers

Answer 1

Answer:

a = 5

Step-by-step explanation:

3(a+3)+6 = 30

subtract 6 from both sides

3(a+3) = 24

divide both sides by 3

a+3 = 8

subtract 3 from both sides

a = 5

Step-by-step explanation:

From the picture attached,

lines 'l' ad 'm' are the parallel lines and line 't' is a transversal intersecting each line at two different points.

From the angles formed at the points of intersection,

∠5 ≅ ∠8 [Vertical angles]

∠5 ≅ ∠4 [Alternate interior angles]

∠5 ≅ ∠1 [Corresponding angles]

Therefore, Options A, D and F will be the correct options.

Write an equation that is parallel to y=4/5x+1?

Answers

Answer:

y=4/5×

Step-by-step explanation:

its parallel. U just have to leave the slope alone but find a different y intercept.

When parallel lines passes through origin (0,0) the the equation of line parallel to [tex]y=\frac{4}{5}x+1[/tex] is

[tex]y=\frac{4}{5}(x)[/tex]

Given :

Given the equation is [tex]y=\frac{4}{5}x+1[/tex]

the given equation is in the form of y=mx +b

where m is the slope and b is the y intercept

[tex]y=\frac{4}{5}x+1\\slope =\frac{4}{5}[/tex]

when two lines are parallel to each other then the slopes are equal

slope of parallel line = slope of given line

slope of parallel line =[tex]\frac{4}{5}[/tex]

When parallel lines passes through origin (0,0) the the equation of line parallel to [tex]y=\frac{4}{5}x+1[/tex] is

[tex]y-0=\frac{4}{5}(x-0)\\\y=\frac{4}{5}(x)[/tex]
