Answer:

x = 1, y =   46\3

y-intercept = 2

slope(m) =  

7 - 2 \3 - 0 =  5 \3

thus,

y =  5 \3 x + 2

then, plug in values

Answer:

B) x = 1, y = 46/3

Step-by-step explanation:

The general equation for a straight line is

y = mx + b

Step 1. Find the <em>slope of the line </em>

The slope m is

m =(y₂ -y₁)/(x₂/x₁)

Two of your points are (0, 2) and (3, 7).

m = (7 – 2)/(3 – 0)

m  = 5/3

Step 2. Find the <em>equation of the line</em>

Use point (0, 2).

2 = ⁵/₃ × 0 + b

2 = 0 + b

b = 2

The equation of the line is

y = ⁵/₃x + 2

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

Step 3.Find the coordinates of the <em>first missing point</em>.

(x, 11/3)

11/3 = ⁵/₃x + 2     Multiply each side by 3

  11 = 5x + 6       Subtract 6 from each side

  5 = 5x              Divide each side by 5

  x = 1

The missing value is x = 1.

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

Step 4. Find the coordinates of the <em>second missing point </em>

(8, y)

  y = ⁵/₃ × 8 + 2   Multiply each side by 3

3y  = 40 + 6        Combine like terms

3y = 46               Divide each side by 3

y = 46/3

The missing value is y = 46/3.

Your three known points give the green line in the graph below.

The orange dot represents the first missing point at (1, 11/3).

The red dot represents the second missing point at (8, 46/3).

Answer:

15, 6 and - 3

Step-by-step explanation:

Given x - y = 3 , then

(a)

5(x - y) = 5(3) = 15

(b)

2x - 2y ← factor out 2 from each term

= 2(x - y) = 2(3) = 6

(c)

y - x ← factor out - 1 from each term

= - 1(x - y) = - 1(3) = - 3

A line of best fit is drawn for the set of points shown on the graph. Which point is an approximate extrapolation for x = 30 fro
Goshia [24]

Answer with explanation:

Equation of Linear Regression line is

 y=1.14 x + 3.805

A line of regression is that line which passes through none of the points, few points or all the points in the two dimensional coordinate plane.It tells value of one variable when another variable is known.

for, x=30

y=1.14 × 30 +3.805

y=34.20 +3.805

y=38.005

y=38 (approx)

So, Ordered pair is , (30,38)

How many cubes with side length of 1/3 cm does it take to fill the prism?​
Vladimir [108]

9514 1404 393

Answer:

  120

Step-by-step explanation:

The dimension across the front in terms of cubes is ...

  5/3 cm = 5×(1/3 cm) = 5 cubes

The front-to-back dimension in terms of cubes is ...

  4/3 cm = 4×(1/3 cm) = 4 cubes

The height in terms of cubes is ...

  2 cm = 6×(1/3 cm) = 6 cubes

Then the volume in terms of cubes is ...

  V = LWH = 5×4×6 = 120 cubes

It will take 120 cubes to fill the prism.
