Answer:

B. (3,0)(0 ,-6)

Step-by-step explanation:

What is intercept.?

Intercept are those points where a given line cuts across a given axis.

So for the equation y = 2x - 6

To find the intercept we will bear in mind that we are looking for two points.

The point where the line cuts both the x axis and the y axis .

And to determine that, we will set both x and y to be equal to zero and then solve for both.

So let x = 0

Y = 2x -6

Y = 2(0) -6

Y = -6

One point = (0 ,-6)

Let y = 0

Y = 2x -6

0 = 2x -6

6 = 2x

X = 3

One point = (3,0)

The two points are

(3,0)(0 ,-6)

Why is substitution a higher level of thinking?

zhuklara [117]

Advocates replacing foreign imports with domestic production. It is based on the premise that a country should attempt to reduce its foreign dependency through the local production of industrialized products. The term primarily refers to 20th-century development economics policies, although it has been advocated since the 18th century by economists such as Fredrick List and Alexander Hamilton.

A car dealership earns a portion of its profit on the accessories sold with a car. The dealer sold a Toyota Camry loaded with ac

lina2011 [118]

Answer:

y = 2666.67

Step-by-step explanation:

Well to solve this we can make a system of equations.

x = cost of car alone

y = cost of accesories,

$\left \{ {{x+y=24000} \atop {x=8y}} \right.$

So now we plug in 8y for x in x + y = 24000.

(8y) + y = 24000

9y = 24000

Divide both sides by 9

y = 2666.666666

or 2666.67 rounded to the nearest hundredth.

Now that we have y we can plug that in for y in x=8y.

x = 8(2.666.67)

x = 21,333.33 rounded to the nearest hundredth.

Thus,

accessories "y" cost around 2666.67.

Hope this helps :)

What two numbers add up two 40 but multiply to get 100

DerKrebs [107]

The two numbers are illustrations of system of equations

The two numbers are 2.7 and 37.3

<h3>How to determine the two numbers?</h3>

Let the numbers be x and y.

So, we have the following equations

x + y = 40

xy = 100

To determine the value of the variables, we simply plot the graph of both equations

From the graph, we have the following result

(x,y) = (2.7, 37.3)

Hence, the two numbers are 2.7 and 37.3

The length of a photograph is 3cm less than twice the width. The area is 54cm^2. Find the dimensions of the photograph.

REY [17]

W= width
l= length= 2w-3

Area= length * width
A= lw
substitute l=2w-3 for l
54= (2w-3)(w)
54= 2w^2 - 3w
subtract 54 from both sides
0= 2w^2 - 3w - 54
factor the polynomial
0= (2w + 9)(w - 6)

Set each set of parentheses equal
to 0 and solve for width.

0=2w+9
-9=2w
-4.5= w NEGATIVE VALUE

0=w-6
6 cm=w

-4.5 is not the answer because it has a negative value. You cannot have a negative side of a photograph. So substitute 6 in to find length.

length= 2w-3
l= 2(6)-3
l= 12-3
l= 9 cm

CHECK:
w= 6cm
l= 9cm
Area= length * width
54= 6*9
54= 54

ANSWER: width= 6cm; length= 9cm

Hope this helps! :)
