infinite solutions because 2(x-2) it equals 2x-4 and that is the first euqation

making 2x-4=2x-4 which is right

Answer:

x=1 and x=3

Step-by-step explanation:

When you factor it you get (x-1) and (x-3) then you subtract the 1 and 3 to the other side which is why the answer is positive.  

Answer:

x = 1, x = 3

Step-by-step explanation:

Equate the expression to zero, that is

x² - 4x + 3 = 0 ← in standard form

(x - 1)(x - 3) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

x - 3 = 0 ⇒ x = 3

The scale factor used is {k} = 164.4.

Scale factor is the ratio of original dimensions to the scaled dimensions.

Given is that Eiffel Tower is 986 feet tall. Caroline built a scale model that is 6 inches tall.

We can write the scale factor as -

{k} = 986/6

{k} = 164.4

Therefore, the scale factor used is {k} = 164.4.

Answer:

slope = -1

Step-by-step explanation:

When you put the equation into slope-intercept form (y=mx+b), where m is the slope of the line, you can see that -1 is the slope.

The slope of the line represented by the given equation is -1.

Given the following equation:

To determine the slope of the line represented by the given equation:

Mathematically, the standard form of an equation of line is given by the formula;

[tex]y=mx+b[/tex]   ....equation 2.

Where:

Equating the two equations, we have:

[tex]y = mx+b = 7-x[/tex]

Comparing eqn 1 and eqn 2, we can deduce that the slope is -1.

Answer:

C

Step-by-step explanation:

Given:

The function is:

[tex]f(x)=10x^5+8x^4-15x^3+2x^2-2[/tex]

To find:

All the possible rational zeros for the given function by using the Rational Zero Theorem.

Solution:

According to the rational root theorem, all the rational roots are of the form [tex]\dfrac{p}{q},q\neq 0[/tex], where p is a factor of constant term and q is a factor of leading coefficient.

We have,

[tex]f(x)=10x^5+8x^4-15x^3+2x^2-2[/tex]

Here,

Constant term = -2

Leading coefficient = 10

Factors of -2 are ±1, ±2.

Factors of 10 are ±1, ±2, ±5, ±10.

Using the rational root theorem, all the possible rational roots are:

[tex]x=\pm 1,\pm 2,\pm \dfrac{1}{2}, \pm \dfrac{1}{5},\pm \dfrac{2}{5},\pm \dfrac{1}{10}[/tex].

Therefore, all the possible rational roots of the given function are [tex]\pm 1,\pm 2,\pm \dfrac{1}{2}, \pm \dfrac{1}{5},\pm \dfrac{2}{5},\pm \dfrac{1}{10}[/tex].

Answer:

208 cm

Step-by-step explanation:

Surface Area = 2(wl+hl+hw)

2(6 × 8 + 4 × 8 + 4 × 6)

2(48 + 32 + 24)

2(104) = 2 × 104

= 208 cm

Answer:

sin62=BD/AB

BD=Sin62×AB

BD=Sin62×15

BD=13.24

ALSO,

Tan C = BD/BC

Tan C = 13.24/24

Tan C = 5.51 / 10

C = Tan^-1 ( 5.51 / 10 )

Answer:

∠BCD = 29°

Step-by-step explanation:

sin 62 = BD/15

0.8829 = BD/15

BD = 13.24

tan ∠BCD = 13.24/24 = 0.5517

∠BCD = 29°

Answer:

Find the gcf, greatest common factor, of 12 and 18 and solve

Step-by-step explanation:

12: 1, 2, 3, 4, 6, 12

18: 1, 2, 3, 6, 9, 18

The gcf is 6, so divide the numerator and denominator by 6.

12 / 6 = 2

18 / 6 = 3

Therefore, 12/18, when relatively prime, is 2/3

Answer:

the principal and the amount is 1,800 and 13,800 respectively

Step-by-step explanation:

The computation of the simple interest and amount for the end of the 3rd year is shown below:

Simple interest is

= Principal × rate of interest × time period

= 12,000 × 5% × 3 years

= 1,800

Now the amount is

= 12,000 + 1,800

= 13,800

hence, the principal and the amount is 1,800 and 13,800 respectively

Answer:

530.66

Step-by-step explanation:

The computation of the area of the cross section is shown below

Given that

Volume = 9208 m^3

Now let us assume the radius be r

So volume = 4 ÷ 3 πr^3

9202.8 × 3 ÷ 4π = r^3

27,608.4 ÷ 4 × 3.14 = r^3

27,608.4 ÷ 12.56 = r^3

2,198.12 = r^3

r = 13

Now the area of the cross section is

= πr^2

= 3.14 × (13)^2

= 530.66
