can you help me with this please​

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

Explanation:

We'll plug x = -10 into each equation shown. If we get y = 4 as an output, then it is one of the answers.

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

A)

y = -x^2 + 6

y = -(-10)^2 + 6

y = -100 + 6

y = -94

We don't get y = 4, so we cross choice A off the list.

The point (-10,4) is not on y = -x^2+6. Instead, the point (-10,-94) is.

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

B)

y = (-1/2)*x - 1

y = (-1/2)*(-10) - 1

y = 5 - 1

y = 4

We can see that x = -10 leads to y = 4. The point (x,y) = (-10,4) is on the line. Choice B is one of the answers.

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

C)

y = (-1/10)*x - 3

y = (-1/10)*(-10) - 3

y = 1 - 3

y = -2

Choice C is not one of the answers since we want y = 4 as an output. So we can cross choice C off the list.

The point (-10,-2) is on the line instead of (-10,4)

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

D)

y = (1/10)x + 5

y = (1/10)*(-10) + 5

y = -1 + 5

y = 4

Choice D is one of the answers

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

E)

y = (1/5)*x^2 - 16

y = (1/5)*(-10)^2 - 16

y = (1/5)*(100) - 16

y = 20 - 16

y = 4

Choice E is one of the answers

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

An alternative method is to graph each equation and see if (-10,4) is on the curve or not. See the diagram below. Only choices B, D and E have (-10,4) on their respective curves.

Answer:

Find "f(6)" __-8__

Find x when "f(x)=2" __x=1__

Step-by-step explanation:

For the first part, we will substitute 6 into the f(x) to get "-2(6)+4" When simplified further, you get "-12+4" which is "-8"

For the second part we will substitute the two as the answer of f(x) "-2x+4=2" Simplifying this further we get "-2x=-2" This means that x=1

Answer:

-3/7, -2/8, -0.2

Step-by-step explanation:

-0.2 = -1/5

We have -3/7, -2/8 and -1/5

For positive b and d:

a/b < c/d if and only if a*d < c*b

-3/7 < -2/8 if and only if -3*8 < -2*7; obviously true

-2/8 < -1/5 if and only if -2*5 < -1*8; -10 < -8; true

so we get -3/7 < -2/8 < -0.2

Step-by-step explanation:

Given:

The system of equation is

[tex]2x+y=8[/tex]

[tex]x-y=10[/tex]

To find:

The value of the system determinant.

Solution:

If two equations of a system of equations are [tex]a_1x+b_1y=c_1[/tex] and [tex]a_2x+b_2y=c_2[/tex], then the system determinant is

[tex]D=\left|\begin{matrix}a_1&b_1\\a_2&b_2\end{matrix}\right|[/tex]

[tex]D=a_1b_2-b_1a_2[/tex]

The given two equations are [tex]2x+y=8[/tex] and [tex]x-y=10[/tex].

Here, [tex]a_1=2,b_1=1,c_1=8, a_2=1,b_2=-1,c_2=10[/tex].

[tex]D=\left|\begin{matrix}2&1\\1&-1\end{matrix}\right|[/tex]

[tex]D=(2)(-1)-(1)(1)[/tex]

[tex]D=-2-1[/tex]

[tex]D=-3[/tex]

The value of the system determinant is -3. Therefore, the correct option is C.

-3

There are a total of 6 x 6 = 36 possible outcomes when a fair die is rolled twice. Of the 36 possible outcomes, there are 6 doubles: 1-1, 2-2, 3-3, 4-4, 5-5, and 6-6. Thus, the probability of getting a double is 6/36 = 1/6.

Answer:

Step-by-step explanation:

1. The area of a circle is given by the formula ...

  A = πr² . . . . . where r is the radius

The radius is shown as 6 cm, so the area is ...

  A = (3.14)(6 cm)² = 113.0 cm²

__

2. The radius is shown as 28 in. We note that this is a number divisible by 7, so we choose 22/7 for π.

  A = (22/7)(28 in)² = 2464 in² . . . . see comment

__

3. The radius is half the diameter, so is 11/2 = 5.5 ft. Then the area is ...

  A = (3.14)(5.5 ft)² = 95.0 ft²

_____

Additional comment

If you use a more exact value of π for problem 2, the area is 2463.0 in². If you use 3.14 as the value of π, the area rounds to 2461.8 in². For these values of pi (3.14 or 22/7), the answer is only good to about 3 significant digits. 2464 has more significant digits, so digits beyond the first 3 may be in error.

Step-by-step explanation:

Inverse of 1/3 = 3

3 x 6 = 18

18 flowerpots can be filled with these 6 bags.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

We have,

Brianna has 6 bags of soil.

Filling one flowerpot requires 1/3 of a bag of soil.

So, the number of flowerpots filled using 6 bags

=  6 / (1/3)

= 6 x 3

= 18 pots

Much like when you divide by a negative number, the sign of the inequality must flip! ... When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side!
