Answer:

y= -3x+1

Step-by-step explanation:

Let's start with the y-intercept (initial value). The y-intercept is where the line intersects the y-axis, so the x value should be 0. Here, the y-intercept is (0,1).

The slope is equivalent to the rise over run. We rise three and go to the left 1 which gives us a slope of negative 3 since we went to the left instead of the right.

Equation for a line:

y=mx+b where m is the slope and b is the y-intercept.

We plug in the slope and y-intercept in and get...

y= -3x+1

Answer:

  • slope: -3
  • initial value: 1
  • equation: y = -3x +1
  • partial variation

Step-by-step explanation:

<u>Slope</u>

To find the slope of the line, it is useful to find two grid intersections that the line passes through. If one of those is on the y-axis, that is a good place to start. Here, that one is (0, 1).

Another can be see up and to the left, at (-1, 4).

The slope formula can be used to find the slope between these points:

  m = (y2 -y1)/(x2 -x1)

  m = (4 -1)/(-1 -0) = 3/-1 = -3

The slope of the line is -3.

__

<u>Initial value</u>:

This is the value that the function has when x=0. It is the y-intercept. We identified that value in the previous section as 1.

The initial value is 1.

__

<u>Equation</u>:

The slope-intercept equation of the line is of the form ...

  y = mx + b . . . . . . . where m is the slope (-3) and b is the y-intercept (1).

Filling in the values we know, the equation is ...

  y = -3x +1

__

<u>Variation</u>:

The line represents "direct variation" only if the y-intercept is zero. That is, the equation will be of the form ...

  y = kx

with no added constant. The value "k" is called the constant of proportionality, or "rate of change."

You will notice the equation for the line on this graph has a y-intercept of 1, so <em>does not represent direct variation</em>. Of the two answer choices, the appropriate one is ...

  Partial Variation

Order six and three tenths repeating, negative six and four ninths, 630%, and −6.1 from least to greatest.
NNADVOKAT [17]

The order of six and three tenths repeating, negative six and four ninths, 630%, and −6.1 from least to greatest is negative six and four ninths, −6.1, 630%, six and three tenths repeating. option D

<h3>Ascending order</h3>

This is the arrangements of numbers from the least to the greatest, that is, from lower value to higher value.

six and three tenths repeating

= 6.333

negative six and four ninths

= -6 4/9

= -6.444

630%

= 630/100

= 6.3

−6.1

From least to greatest:

  • negative six and four ninths
  • −6.1
  • 630%
  • six and three tenths repeating

Therefore, the order six and three tenths repeating, negative six and four ninths, 630%, and −6.1 from least to greatest is negative six and four ninths, −6.1, 630%, six and three tenths repeating. option D

The areas of two similar triangles are 72dm2 and 50dm2. The sum of their perimeters is 226dm. What is the perimeter of each of t
zloy xaker [14]

Answer:

103=  p small

plarge = 123

Step-by-step explanation:

We know that the the ratio of the areas is the scale factor squared/

Larger triangle over smaller triangle

72

----- = scale factor ^2

50

simplify by dividing by 2 on top and bottom

36

----- = scale factor ^2

25

Take the square root of each side

sqrt(36)

-------------- = sqrt(scale factor ^2)

sqrt(25)

6

-------------- = scale factor

5

The ratio of the perimeters is the scale factor

p large             6

-------------- = ----------------

 p small                5

Using cross products

6 p large = 5 p small

We know the sum is 226

p large + p small = 226

p large = 226 - p small

We have 2 equation and 2 unknowns

6 p large = 5 p small

Substitute for p large

6 (226 - p small) = 5 p small

1356 - 6 p small = 5 p small

Add 6 p small to each side

1356 = 11 p small

divide by 11

1356/11 =  p small

P large = 226-1356/11

p large = 2486/11-1356/11

plarge = 1130/11

The solution requires whole number answers so

1356/11 =  p small

123.27 which rounds to 123

plarge = 1130/11

plarge = 102.7272 = 103
