========================================================

Explanation:

6)

Let's solve for y to get the equation in slope intercept form y = mx+b

[tex]5x+3y = 15\\\\3y = -5x+15\\\\y = \frac{-5x+15}{3}\\\\y = \frac{-5x}{3}+\frac{15}{3}\\\\y = -\frac{5}{3}x+5\\\\[/tex]

That last equation matches with y = mx+b to get

m = -5/3 = slope

b = 5 = y intercept

To graph this, we plot the y intercept at (0,5). Then move down 5 and to the right 3 to arrive at (3,0) as the second point. This movement is directly tied to the slope. We only need two points to graph a straight line.

---------------------------------

7)

The equation y = -x+2, aka y = -1x+2, is already in slope intercept form

m = -1 = slope

b = 2 = y intercept

Start at (0,2) which is the location of the y intercept. Move down 1 and to the right 1 due to the slope -1/1 = -1. This should move us to the point (1,1). Connect the two points (0,2) and (1,1) with a straight line to finish up the graph.

---------------------------------

8)

We start with the origin (0,0) because the y intercept of y = 3x is 0. It might help to think of y = 3x as y = 3x+0

Then we move up 3 units and to the right 1 unit to get to (1,3) as our next point. Connect the two points with a straight line

slope = 3

y intercept = 0

Once again, the graphs are shown below.

Answer:

Step-by-step explanation:

a1 = -  13

an = a_(n - 1) + 6

a2 = a_(2 -1) + 6

a2 = a1 + 6

a2 = - 13 + 6

a2 = - 7

a3 = a2 + 6

a3 = - 7  + 6

a3 = - 1

a4 = a3 + 6

a4 = - 1 + 6

a4 = 5

a5 = a4 + 6

a5 = 5 + 6

a5 = 11

a_n=a_{n-1}+6

Therefore, you will get the answer $2925

PS: for the formula: I = PRT, I represents the money you earn when you deposit money in the bank for several years. P is the principal which is also the money you deposit into the bank at the beginning. R represents the rate of interest, which is the percent of interest of your principal. Last but not least, T represents the time you deposit ur money into the bank. But notice that the time is years. Which means 1 year is 1, 5 years are 5, and 9 months are 9/12 year.

Answer:

2/3, 5/6, 2/9, 11/18

Step-by-step explanation:

Answer:

2/9, 11/18, 2/3, 5/6

Step-by-step explanation:

multipy all the denominators and numerators by what it takes to get 18

ie. 2/3 *6 =12/18

etc.

We want to find parallel lines to the given lines, such that also meet some given restrictions.

The solutions are:

A) y = 0.5*x - 6

B) two solutions:

    y = 0.5*x + 4

    y = 0.5*x

Before start answering, a general line is given by:

y = a*x + b

Where a is the slope and b is the y-intercept.

Another line will be parallel this if and only if it has the same slope and a different y-intercept.

A) We want to find a line that is parallel to y = 0.5*x + 10 and that intersects y = -1.5*x

So we want another line with a slope of 0.5, then the correct option is:

y = 0.5*x - 6

How do we know that this intercepts the other line?

Because if two lines have different slopes, then the lines are not parallel, meaning that at some given point the lines intercept.

B) Similarly, now we want a line parallel to:

y = 0.5*x + 10

And that intersects:

y = -1.5*x

The correct options are the ones with slope equal to 0.5, then we have two correct options:

y = 0.5*x + 4

y = 0.5*x

  (b)  Transitive property of congruence

Step-by-step explanation:

The relations involved are all congruence relations, eliminating choices A and C.

The symmetric property tells you ...

  if A ≅ B, then B ≅ A

It is not applicable in this case.

Step-by-step explanation:

a parallelogram's area is represented by the equation l * h where l is the length and h is the height

the length is 10 the height is h and area is 40 so we can do this

10h = 40

h = 4

Answer:

  55°

Step-by-step explanation:

Let x represent the measure of the smaller angle. Then the larger angle is ...

  3x -50

and the sum of the angles is ...

  x + (3x -50) = 90

  4x = 140 . . . . . . . . . add 50 and simplify

  x = 35 . . . . . . divide by 4 -- the smaller angle

  90 -35 = 55 . . . . the larger angle

The larger angle measures 55°.

Answer:

[tex]f(x)=\frac{4}{3}x+1[/tex]

Step-by-step explanation:

The graphed function is:

[tex]f(x)=\frac{4}{3} x-2[/tex]

Now, a system of linear equations with no solution means 2 lines that never intersect at any point. The only way that can be true is if both lines are parallel, or have the same slope.

You can write any equation that has the same slope, I'll do this one:

[tex]f(x)=\frac{4}{3}x+1[/tex]

You can confirm that they are parallel in the attached image.

The reason they cannot intersect is because the point at which 2 lines intersect is the solution. If they intersect at any point, there is a solution, and that solution is that point.
