Step-by-step explanation:

Try this option:

1) for the given function 'f': the the axis of its symmetry is x= -2;

2) for the function 'g':

g(x)=4x²-16x+12; ⇔ g(x)=4(x²-4x+3); ⇔ g(x)=4(x-1)(x-3).

It means the axis of its symmetry is x=2.

Answer:other number is 11,4

Step-by-step explanation:

Answer:

SMALLER NUMBER = 14

BIGGER NUMNER = 34

Step-by-step explanation:

Two equations can be derived from the question

a + 2b = 62 equation 1

3a - b = 116  equation 2

a = bigger number

b = smaller number

multiply equation 1 by 3

3a + 6b = 186 equation 3

subtract equation 2 from 3

5b = 70

b = 14

substitute for b in equation 1

a + 28 = 62

a = 34

Answer:

(x - 3)² + (y + 5)² = 10

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k) = (3, - 5 ) , then

(x - 3)² + (y - (- 5) )² = r² , that is

(x - 3)² + (y + 5)² = r²

r is the distance from the centre to a point on the line

Calculate r using the distance formula

r = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (3, - 5) and (x₂, y₂ ) = (6, - 4)

r = [tex]\sqrt{(6-3)^2+(-4+5)^2}[/tex]

  = [tex]\sqrt{3^2+1^2}[/tex]

  = [tex]\sqrt{9+1}[/tex]

   = [tex]\sqrt{10}[/tex] ⇒ r² = ([tex]\sqrt{10}[/tex] )² = 10

(x - 3)² + (y + 5)² = 10 ← equation of circle

Answer:

i dont know

Step-by-step explanation:

Answer:

D.

Step-by-step explanation:

3b = 5$

3b = 6a

3b = 3 bags

6a = 6 apples

A. It costs 3.60 for 1 bag of apples

3.60 + 3.60 = 60 + 60 = 120 + 3 = 123 + 3 = 126

Meaning it would cost 126 for 3 bags of apples making this a incorrect option

B. It costs 3.60 for 1 apple

B is wrong because its one apple and if we were to subtract the apple would probably only cost a few change not 3$ and 60 cents.

C. The cost of 9 bags of apples is 30$

9b = 21a, its either c or d but I'm pretty sure its D!

D. The cost of 108 apples is 30$

D is correct

Answer:

isosceles right

Step-by-step explanation:

It is an isosceles right angled triangle because according to the figure it's two sides are equal which means it is isosceles triangle and there is 90 degree symbol which denotes right angle.

An Isosceles Right Triangle is a right triangle that consists of two equal length legs. Since the two legs of the right triangle are equal in length, the corresponding angles would also be congruent. Thus, in an isosceles right triangle, two legs and the two acute angles are congruent.

Answer:

it is a right angled triangle

Step-by-step explanation:

Answer:

35

Step-by-step explanation:

Cause they both add up to a right angle which is 90 degrees. so 90-55=35

∠angle, a and ∠angle, b are complementary angles. ∠ an ∠angle, a measures 5 5 ∘ 55 ∘ 55, degrees. so we can conclude that ∠b = 35.

The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.

∠angle, a and ∠angle, b are complementary angles.

∠ an ∠angle, a measures 5 5 ∘ 55 ∘ 55, degrees.

we want to measure ∠ b

We know that the sum of Complementary angles is equal to 90 degrees.

so to find the measure of angle B we subtract the given angle from 90

∠ b + ∠ a = 90

∠ b + 55 = 90

∠ b = 90-55

∠ b =35

so we can conclude that ∠b = 35.

Point on ray PQ

A ray is a line with a starting point, and  extends infinitely in the other direction.

So;

Ray PQ implies that.

P is the starting point, and it extends towards Q direction (however, it is endless).

Towards the direction of Q, we have points R and S.

This implies that R and S are on ray PQ.

Answer:

[tex](a)\ x = 3y - 2[/tex]

Equations that can create consistent and independent systems

For a pair of equation to have consistent and independent systems, the equations must have different slopes.

An equation of the form [tex]y = mx + c[/tex] has m has its slope.

In [tex]y =3x -2[/tex]

[tex]m = 3[/tex] --- slope

Considering the options

[tex](a)\ x = 3y - 2[/tex]

Make y the subject

[tex]x = 3y - 2[/tex]

[tex]3y = x+2[/tex]

Divide by 3

[tex]y = \frac{1}{3}x+\frac{2}{3}[/tex]

The slope is:

[tex]m_1 = \frac{1}{3}[/tex]

Hence, (a) can make a consistent and independent system with [tex]y =3x -2[/tex]

[tex](b)\ y = -3x - 2[/tex]

The slope is:

[tex]m= -3[/tex]

Hence, (b) can make a consistent and independent system with [tex]y =3x -2[/tex]

[tex](c)\ y = 3x + 2[/tex]

The slope is:

[tex]m=3[/tex]

Hence, (c) cannot make a consistent and independent system with [tex]y =3x -2[/tex]

[tex](d)\ 6x - 2y = 4[/tex]

Make y the subject

[tex]2y = 6x -4[/tex]

Divide by 2

[tex]y = 3x -2[/tex]

The slope is

[tex]m =3[/tex]

Hence, (d) cannot make a consistent and independent system with [tex]y =3x -2[/tex]

[tex](e)\ 3y - x = -2[/tex]

Make y the subject

[tex]3y = x -2[/tex]

Divide by 3

[tex]y = \frac{1}{3}x -\frac{2}{3}[/tex]

The slope is:

[tex]m = \frac{1}{3}[/tex]

Hence, (e) can make a consistent and independent system with [tex]y =3x -2[/tex]

Replace x and y in the equation with what they tell you x and y equal.

Answer:

The series 64, 16, 4, 1 is convergent.

Step-by-step explanation:

Let be [tex]\{x_{1}, x_{2},...,x_{n}\}[/tex] the set of values of the series. A series is convergent if and only if:

[tex]\frac{x_{i + 1}}{x_{i}} < 1, \, \forall\,i\in \mathbb{N}[/tex] (1)

If we know that [tex]x_{1} = 64[/tex], [tex]x_{2} = 16[/tex], [tex]x_{3} = 4[/tex] and [tex]x_{4} = 1[/tex], then the convergence ratio of each pair of consecutive values are, respectively:

[tex]\frac{x_{2}}{x_{1}} = \frac{1}{4}[/tex], [tex]\frac{x_{3}}{x_{2}} = \frac{1}{4}[/tex], [tex]\frac{x_{4}}{x_{3}} = \frac{1}{4}[/tex]

Hence, the series 64, 16, 4, 1 is convergent.

Answer: a. x=4 b. x=17.5

Step-by-step explanation:

a. 5x/2+1=11

subtract 1 from both sides : 5x/2=10

multiply both sides by 2 : 5x=20

divide both sides by 4 : x=4

b. 2x/7-3=2

add 3 to both sides : 2x/7=5

multiply both sides by 7 : 2x=35

divide both sides by 2 : x=17.5

Answer:

15 ≤ w ≤ 19

Step-by-step explanation:

Given that :

Length of garden = 14 feets

Perimeter must be atleast 58 but no more than 66

The range of value for the width ;

Perimeter = 2 length + 2 width

Perimeter = 2(14) + 2w

If perimeter = 58

58 = 28 + 2w

58 - 28 = 2w

30 /2 = w

w = 15

If perimeter = 66

66 = 28 + 2w

66 - 28 = 2w

38 = 2w

w = 38 / 2

w = 19

Range of the width should be atleast 15 and not more Than 19

Hence,

15 ≤ w ≤ 19

Answer: [tex]15\ ft,6\ ft[/tex]

Step-by-step explanation:

Given

The area of a rectangular wall of a barn is [tex]135\ ft^2[/tex]

Suppose the width of the wall is [tex]x[/tex]

So, the length of the wall is [tex]6+x[/tex]

Area can be written as the product of length and width

[tex]\Rightarrow (6+x)x=135\\\Rightarrow 6x+x^2=135\\\Rightarrow x^2+6x-135=0\\\Rightarrow x=\dfrac{-6\pm \sqrt{6^2-4(1)(-135)}}{2(1)}\\\\\Rightarrow x=\dfrac{-6\pm 24}{2}\\\\\Rightarrow x=-15,9[/tex]

neglecting the negative value, width of the wall is [tex]9\ ft[/tex]

So, the length of the wall is [tex]9+6=15\ ft[/tex]

Answer:

lesser x = -6

greater x  = 6

Step-by-step explanation:

-5x² + 180 = 0

5x² = 180

x² = 36

x = ±6

Answer:

x = - 6, x = 6

Step-by-step explanation:

Given

h(x) = - 5x² + 180

To find the zeros let h(x) = 0 , that is

- 5x² + 180 = 0 ( subtract 180 from both sides )

- 5x² = - 180 ( divide both sides by - 5 )

x² = 36 ( take the square root of both sides )

x = ± [tex]\sqrt{36}[/tex] = ± 6 , then

lesser x = - 6

greater x = + 6
