Which equation best represents the line? (10 Points)

Mathematics
1 answer:
son4ous [18]3 years ago

Answer: D. y = 3x − 1

Step-by-step explanation:

The equation of a straight line can be represented in the slope-intercept form, y = mx + c

Where c = intercept

Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis

change in the value of y = y2 - y1

Change in value of x = x2 -x1

y2 = final value of y

y 1 = initial value of y

x2 = final value of x

x1 = initial value of x

From the graph,

y2 = 2

y1 = - 1

x2 = 1

x1 = 0

Slope,m = (2 - - 1)/(1 - 0) = 3/1 = 3

To determine the intercept, we would substitute x = 1, y = 2 and m= 3 into y = mx + c

y = mx + c. It becomes

2 = 3 × 1 + c = 3 + c

c = 2 - 3 = - 1

The equation becomes

y = 3x - 1

Answer:

(-3/2, 6)

Step-by-step explanation:

(-3,8) (6,-4)

As we move along the line segment with endpoints (-3,8) and (6,-4) from  (-3,8) to (6,-4) x increases by 9 units (from -3 to 6) and y decreases by -12 units (from 8 to -4).

for ratio of 1:5

Since 1+5=6, the point we are looking for is 1/6 of the way from (-3,8) to (6,-4).  

So, the desired point is

(-3 + (1/6)(9), 8 - (1/6)(12) )

= (-3 + 3/2 , 8 - 2)

= ( (-6 + 3)/2, 6)

= (-3/2, 6)

oksian1 [2.3K]
<h3>I'll teach you how to solve 15x ^2 −4x−4</h3>

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

15x ^2 −4x−4

Break the expressions into groups:

(15x^2+6x) + (-10x-4)

Factor out 3x from 15x^2+6x:

3x(5x+2)

Factor out -2 from -10x-4:

-2(5x+2)

3x(5x+2) -2(5x+2)

Factor out common term 5x+2:

(5x+2)(3x-2)

Your Answer Is (5x+2)(3x-2)

plz mark me as brainliest :)

A 3-ply core/sheath yarn consists of a 30/1 (core) yarn, and two 20/1 (sheath) yarns. Analysis of the plied yarn showed that 1 m
Alex

Answer:

0.000462

Step-by-step explanation:

From the given information:

The cotton count of the piled yarn is the ratio of the simple weight in (g) with the length by the simple length with weight.

Mathematically:

Cotton count = \dfrac{simple \ weight \ in (g) \times \ length }{simple \ length \times unit \ weight }

Cotton count = \dfrac{1 \times 0.001 }{0.108 \times 20}

\mathbf{ Cotton \  count = 0.000462}

What value of c is needed to complete the square?<br><br> X2 + 10x + c = -3+ c
Vikentia [17]

Answer:

Step-by-step explanation:Let's solve for c.

x2+10x+c=−3+c

Step 1: Add -c to both sides.

x2+c+10x+−c=c−3+−c

x2+10x=−3

Step 2: Add -x^2 to both sides.

x2+10x+−x2=−3+−x2

10x=−x2−3

Step 3: Add -10x to both sides.

10x+−10x=−x2−3+−10x

0=−x2−10x−3

Step 4: Divide both sides by 0.

0

0

=

−x2−10x−3

0

c=

−x2−10x−3

0

Answer:

c=

−x2−10x−3/0

hope it helps :D
