The length of a rectangle is 10 more than 10 twice the width , if the perimeter is 80inches find the length the width

Answer: m < 1

x² - 2x + m = 0 (*)

a = 1   b = -2    c = m

Δ = b² - 4ac = 4 - 4m

(*) has 2 district real solutions => Δ > 0

⇔ 4 - 4m > 0

⇔ 4m < 4

⇔ m < 1

Given:

[tex]y=-\dfrac{3}{2}x+2[/tex]

To find:

The set of points that includes all of the solutions for the given equation.

Solution:

From the given equation, it is clear that y-values depend on the x-values.

If x is a real number, then y-values are real numbers such that [tex]y=-\dfrac{3}{2}x+2[/tex].

So, the set of points that includes all of the solutions for the given equation is defined as [tex]\left(x,-\dfrac{3}{2}x+2\right)[/tex]  for all real numbers.

Therefore, the correct option is B.

Answer:

The rental costs $2 per mile (third from top answer)

Reasoning:

The graph on the side follows the slops of y=2x (rise of 2, run of 1) , therefore at x=1, we know that the y value must be 2.

Meaning The third option (The rental costs $2 per mile) is the only

correct answer

I hope this helps you and good luck!

Answer:

Y = [tex]x^{2}[/tex] - x - 42

Step-by-step explanation:

You can use the foil method

first, outside, inside, last

multiply the x’s together, the x times -7, the 6 times x, and then 6 times -7

Y = [tex]x^{2}[/tex] - x - 42

Answer:

80.6%

Step-by-step explanation:

Given that :

Total construction crew = 36

Number present in a certain day = 29

Percentage present on that day :

(Number present / total number) * 100%

(29 / 36) * 100%

0.8055555 * 100%

80.555%

= 80.6%

Answer:

Step-by-step explanation:

y = 0.25x + 8

(0, 8) are coordinates of y=intercept

y = 0.25 × 2 + 8 = 8.50

(2, 8.50)

The last table represnts the given equation.

The fourth table among all the options contains values that satisfy the equation y = 0.25x + 8.

An equation is a combination of two or more expressions, all equal to each other.

Let's check every table if every point in them satisfies the equation y = 0.25x + 8,

Table 1:

To check if (0, 8) satisfies the given equation,

RHS: 0.25 × 0 + 8 = 0 + 8 = 8

LHS: 8 = RHS

This point satisfies the equation.

To check if (2, 8.25) satisfies the given equation,

RHS: 0.25 × 2 + 8 = 0.50 + 8 = 8.50

LHS: 8.25 ≠ RHS

This point does not satisfy the equation.

Table 2:

To check if (0, 0) satisfies the given equation,

RHS: 0.25 × 0 + 8 = 0 + 8 = 8

LHS: 0 ≠ RHS

This point does not satisfy the equation.

Table 3:

To check if (0, 8.25) satisfies the given equation,

RHS: 0.25 × 0 + 8 = 0 + 8 = 8

LHS: 8.25 ≠ RHS

This point does not satisfy the equation.

Table 4:

To check if (0, 8) satisfies the given equation,

RHS: 0.25 × 0 + 8 = 0 + 8 = 8

LHS: 8 = RHS

This point satisfies the equation.

Similarly, all the points can be verified that they satisfy the equation.

Thus, all values in Table 4 satisfy the given equation.

Answer:

  [tex]\dfrac{20+5\sqrt{3}}{13}[/tex]

Step-by-step explanation:

Multiply numerator and denominator by the "conjugate" of the denominator.

  [tex]\dfrac{5}{4-\sqrt{3}}=\dfrac{5(4+\sqrt{3})}{(4-\sqrt{3})(4+\sqrt{3})}=\dfrac{20+5\sqrt{3}}{4^2-(\sqrt{3})^2}=\boxed{\dfrac{20+5\sqrt{3}}{13}}[/tex]

Answer:

The answer is the first option x(x-4)(x-1)/2(x+4).

Step-by-step explanation:

because when you simplify after multiplying the denominator is 2x+8 when you simplify that its 2(x+4) and for the numerator after multiplying you get x^3−5x^2+4x when you simply that you get x(x-4)(x-1). Answer would be x(x-4)(x-1)/2(x+4).

Answer:

1.55

Step-by-step explanation:

[tex]2(x + 0.7) = 6(x – 0.8)​[/tex]

Using the distributive property of addition over multiplication we get

[tex]2x+1.4=6x-4.8[/tex]

Take the like terms to one side and change their signs accordingly

[tex]1.4+4.8=6x-2x[/tex]

[tex]\Rightarrow 6.2=4x[/tex]

[tex]\Rightarrow x=\dfrac{6.2}{4}[/tex]

[tex]\Rightarrow x=1.55[/tex]

The value of [tex]x[/tex] is 1.55.

In order to make sure this value is correct we can substitute the value of x in the equation

[tex]2(1.55+0.7)=6(1.55-0.8)\\\Rightarrow 2\times 2.25=6\times 0.75\\\Rightarrow 4.5=4.5[/tex]

So, both sides are equal hence the value of [tex]x [/tex]is 1.55.
