Step-by-step explanation:

Answer:

(-1,1),(-3,-19)

Step-by-step explanation:

y=−3x²−2x+2     (1)

10x−y=−11

y=10x+11    (2)

−3x²−2x+2 = 10x+11

3x² + 12x + 9 = 0

x²  + 4x + 3 = 0

(x + 1)(x+3) = 0

x= -1 or x = -3

y = 1 or y = -19

The solutions of the equations y = −3x² − 2x + 2 and 10x − y = −11 will be (-1, 1) and (-3, -19).

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The equations are given below.

y = −3x² − 2x + 2         ...1

10x − y = −11                ...2

From equations 1 and 2, then we have

10x + 11 = −3x² − 2x + 2

3x² + 12x + 9 = 0

x² + 4x + 3 = 0

x² + 3x + x + 3 = 0

x(x + 3) + 1(x + 3) = 0

(x + 3)(x + 1) = 0

x = -1, -3

The value of y at x = - 1 is given as,

y = 10(-1)  + 11

y = 1

The value of y at x = -3 is given as,

y = 10(-3)  + 11

y = - 19

The solutions of the equations y = −3x² − 2x + 2 and 10x − y = −11 will be (-1, 1) and (-3, -19).

Answer:

119

Step-by-step explanation:

151 is the outside of the angle so you do 180-151 which is 29 and that plus 32 which is 61 and then 180-61 which is 119

Answer:

x = 119°

Step-by-step explanation:

180° - 151° = 29°

so now we have two angles: 29° and 32°.

32° + 29° + x = 180°

61° + x = 180°

x = 119°

Given:

The equation is:

[tex]8x^3=(-2x)A[/tex]

To find:

The missing factor AAA that makes the equality true.

Solution:

We have,

[tex]8x^3=(-2x)A[/tex]

Divide both sides by -2x to isolate A.

[tex]\dfrac{8x^3}{-2x}=A[/tex]

[tex]-4x^2=A[/tex]

Therefore, the value of A is [tex]-4x^2[/tex].

Answer:

-2/3

Step-by-step explanation:

h(x)=2x-6/4x^2+8

You know that h is equal to -1 so you have to plug that into x.

2(-1)-6/4(-1)^2+8. Simplify this to get -2-6/4+8 which is equal to -8/12. The GCM of 8 and 12 is 4 so you have to divide both sides by 4. This will make the fraction -2/3.

Answer: [tex]h(-1) = \frac{-2}{3}[/tex]

Step-by-step explanation:

You simply substitute -1 for x

h (-1) = 2 (-1) - 6 ÷ (4 × -1² + 8)

h (-1) = (-2 - 6) ÷ (4 × 1 + 8)

h (-1) = (-2 -6) ÷ (4 + 8)

h (-1) = -8 ÷ 12 = -2 ÷ 3

h (-1) = ⁻²/₃

Answer:2444(new price after discount)

Step-by-step explanation:looked it up

2600-156

156(discount amount)

Answer:

Step-by-step explanation:

For the first, simply plug in the value of x given (x = 2) into the equation: [tex]\left\frac{3}{4}x^2 + 5\right.|_{x=2} = \frac{3}{4}\left ( 2^2 \right )+5 = 8.[/tex]

So, 8 would be your answer.

For the second, the sum of x and 2 would be expressed as x + 2. Twice this sum would be written as 2(x+2). Finally, 8 less than twice that sum would be written as 2(x+2) - 8, which would be your expression.

For the last question, the coefficient refers to the number directly in front of the variable, x. So you need only to check what the x would simplify to in each equation and look for the expression where x has no coefficient (i.e., its coefficient is 1). For Hunter, the coefficient would be 15 (5 × 3x = 15x); for Michael, the coefficient would be 11 (6x + 5x = 11x); for Nate, the coefficient would be 1 (x = 1x); and for Spencer, the coefficient would be 2 (2x = 2x). Thus, Nate's expression has a coefficient of 1 when simplified.

Answer:

1.sector 2. chords

Step-by-step explanation:

chord of a circle is a straight line segment whose endpoints both lie on a circular arc. ... More generally, a chord is a line segment joining two points on any curve, for instance, an ellipse. A chord that passes through a circle's center point is the circle's diameter.

Mean = 28.3 , Median = 28.5, Mode = 35, Standard deviation = 5.2

(All of the above are rounded off to one decimal place)

The given data are : 20, 22, 26, 27, 30, 31, 35, 35

We know that, mean = (sum of samples)/(no. of samples)

                                   = (20+22+26+27+30+31+35+35)/8

                                   = 226/8 = 28.25 = 28.3 (approx)

Here, median = (sum of 4th & 5th sample)/2

                       = (27+30)/2 = 57/2 = 28.5

Since 35 appears highest number of times, i.e. 2 times, then we can say that mode is equals to 35

Standard deviation = √{(20-28.3)²+(22-28.3)²+(26-28.3)²+(27-28.3)²+(30-28.3)²+(31-28.3)²+(35-28.3)²+(35-28.3)²}/8

= √{68.89+39.69+5.29+1.69+2.89+7.29+44.89+44.89}/8

= √(215.52/8) = √(26.94) = 5.190 = 5.2 (approx)
