Answer:

From the points, the x coordinates are the same. With this similarity, the slope of the line would be undefined and it would result as an error to the point-slop formula of the line.

$\bf (\stackrel{x_1}{-3}~,~\stackrel{y_1}{-1})~\hspace{10em} slope = m\implies 4 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-(-1)=4[x-(-3)] \\\\\\ y+1=4(x+3)\implies y+1=4x+12\implies y=4x+11$

Five pounds is equal to 2.268 kilograms. How many kilograms is 2 pounds?

Tema [17]

Given:

5 pounds = 2.268 kilograms

To find:

The number of kilograms in 2 pounds.

Solution:

We have,

5 pounds = 2.268 kilograms

Divide both sides by 5.

1 pounds = $\dfrac{2.268}{5}$ kilograms

1 pounds = 0.4536 kilograms

Multiply both sides by 2.

2 pounds = 2×0.4536 kilograms

2 pounds = 0.9072 kilograms

Therefore, the correct option is B.

You could interpret them as system of equation and answer the question easily

from A

-4x + y + x + w =1

write in same form from A

as this system has five variables and four of them are unknowns it means the unique solution is not possible

So, det (A) = 0

Katie wants to create a rectangular frame for a picture. She has 60 inches of material. If she wants the length to be 3 more tha

Fofino [41]

Answer:

Largest possible length is <em>21 inches</em>.

Step-by-step explanation:

Given:

Total material available = 60 inches

Length to be 3 more than twice of width.

To find:

Largest possible length = ?

Solution:

As it is rectangular shaped frame.

Let length = $l$ inches and

Width = $w$ inches

As per given condition:

$l = 2w+3$ ..... (1)

Total frame available = 60 inches.

i.e. it will be the perimeter of the rectangle.

Formula for perimeter of rectangle is given as:

$P = 2 \times (Width + Length)$

Putting the given values and conditions as per equation (1):

$60 = 2 \times (w+ l)\\\Rightarrow 60 = 2 \times (w+ 2w+3)\\\Rightarrow 60 = 2 \times (3w+3)\\\Rightarrow 30 = 3w+3\\\Rightarrow 3w = 27\\\Rightarrow w = 9 \ inch$

Putting in equation (1):

$l = 2\times 9+3\\\Rightarrow l = 21\ inch$

So, the answer is:

Largest possible length is <em>21 inches</em>.
