The solution of the system of inequalities is the intersection region of all the solutions in the system. Example 1: Solve the system of inequalities by graphing: y≤x−2y>−3x+5. First, graph the inequality y≤x−2 .

Answer:

It would be a quadratic function

Step-by-step explanation:

If you plot all the points, you will see that it forms a parabola, since quadratic equations will form a parabola on a coordinate plane, that would be the correct answer.

Answer:

quadratic

I had this question as well it's right for plato

Answer:

B. 2 years

Step-by-step explanation:

use y = mx + b

y = total number of sell outs = 168

m = sell outs per month = 7

x = months

b is not needed for this

168 = 7x

divide both sides by 7

x = 24

divide 24 by 12 to get the number of years

years = 2

Answer:

the answer to this question is B. 2 years

Answer:

A) -8/5

Step-by-step explanation:

First, convert -8/5 and -5/8 to decimals

-8/5 = -1.6

-5/8 = -0.625

-0.5 is greater than -0.625 because it is closer to 0.

So, the only number less than -0.625 is -8/5, which is equivalent to -1.6

So, the correct answer is A) -8/5

Answer:

5026.55

Step-by-step explanation:

A=πr2=π·402≈5026.54825

Answer:

A

Step-by-step explanation:

We have the equation:

[tex]x^2-2x-2=0[/tex]

We can use the quadratic formula. In this case, a = 1, b = -2, and c = -2. Hence:

[tex]\displaystyle x=\frac{-(-2)\pm\sqrt{(-2)^2-4(1)(-2)}}{2(1)}[/tex]

Evaluate:

[tex]\displaystyle x=\frac{2\pm\sqrt{12}}{2}[/tex]

Simplify:

[tex]\sqrt{12}=\sqrt{4}\cdot\sqrt{3}=2\sqrt{3}[/tex]

Hence:

[tex]\displaystyle x=\frac{2\pm2\sqrt{3}}{2}[/tex]

Divide:

[tex]x=1\pm\sqrt3[/tex]

The correct answer is A.

Answer:

The ordered pair (15, 12) means that 15 pounds of beans cost $12.

Step-by-step explanation:

(20, 16)

(x, y)

x is along the x-axis and y is along the y-axis.

x = 20 = 20 pounds of beans

y = 16 = 16 is the cost of the beans

(15, 12)

x = 15 is 15 pounds of beans

y = 12 is 12 for the cost of the beans

Answer: 15 pounds of beans costs 12 dollars

Step-by-step explanation:

if the x-axis represents the pounds of beans, then any x-coordinate will be beans.

Answer:

uhh... that is impossible to know since we don't know the value 'y'

Step-by-step explanation:

Answer:

y = - 3

Step-by-step explanation:

Given the 2 equations

6x + 11y = - 3 → (1)

4x + y = = 17 → (2)

Multiplying (1) by 4 and (2) by - 6, then adding will eliminate the term in x

24x + 44y = - 12 → (3)

- 24x - 6y = - 102 → (4)

add (3) and (4) term by term to eliminate x

0 + 38y = - 114

38y = - 114 ( divide both sides by 38 )

y = - 3

Answer:

[tex]120x^4\sqrt{2}[/tex]

Step-by-step explanation:

First we need to break down the numbers in the radicals into its factors

so

12= 3*2*2

x³=x*x*x

Which means we have

[tex]10\sqrt{3*2*2*x*x*x}=20x\sqrt{3x}[/tex]

and

[tex]2\sqrt{2*3*x*x*x*x*x} =2x^{2} \sqrt{6x}[/tex]

Because the radicand (the small number that goes up top) are the same we can just mulitply the two from here

which means we have

[tex](20x*2x^2)\sqrt{3x*6x}=40x^3\sqrt{18x^2} \\\sqrt{18x^2}=\sqrt{2*3*3*x*x} =3x\sqrt{2} \\=120x^4\sqrt{2}[/tex]

Answer:

Step-by-step explanation:

i cant give you an exact answer but look up the formula for trapezoid and look up the formula for triangle and you will get your answer.

Answer:  Area 89m^2

Step-by-step explanation:

To find the area of the rectangle we multiply

Base * Height = Area

8 * 13 = 104

Now we find the area that isn't shaded

I inference that the base of the triangle is 5m  

5 * 6 = 30

Now divide that by 2

30/2 = 15

Subtract 15 from 104

104 - 15 = 89m^2

Answer:

about 48 miles a week

Step-by-step explanation:

2500 divided by 52 (number of weeks in a year)=

625 divided by 13=  48.076923

about 48 miles

Answer:

The answer is is 48.1 miles Every week

Step-by-step explanation:

We know that there are 52 weeks in the year and beyond 2500 mpt now we can calculate the number of miles that are conducted every week through

[tex] \frac{2500}{52} = 48.1 \:[/tex]

b one root is negative of the other root

Answer:

x = 53

Step-by-step explanation:

Similar means that the corresponding angles are congruent (the same) - basically what this means is that ∠L ≅ ∠G, ∠M ≅ ∠J, and ∠N ≅ ∠H.

Since we know that the angle measures in a triangle should add up to 180 and we know the measures of ∠L and ∠M already, we can do

180 =  67 + 60 + N

So, N = 180 - (67 + 60) = 180 - 127 = 53.

Since ∠N ≅ ∠H, ∠H = 53.
