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:

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:

109 is the 22nd term

Step-by-step explanation:

Answer:

109

Step-by-step explanation:

a = 4

d = 5

[tex]a_{22} = a + 21d[/tex]

[tex]a_{22} = 4 + 21(5)\\[/tex]

[tex]a_{22} = 4 + 105[/tex]

[tex]a_{22} = 109[/tex]

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.

You should be able to solve this easily just by drawing the tunnel and the bus (you may use 1cm for 1m). Notice how the bottom of the tunnel, the side of the bus, and a radius of the tunnel form a right-angled triangle. All you need to do is to find the sides of the triangle.

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:

wait what are the two lines in the middle of A and B are the = signs?

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

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

Step-by-step explanation:

I searched for a complex plane graph and put in each answer and this was the closest.

Cube root of [tex]1+i[/tex] is represented by expression [tex]\sqrt[3]{1+i}[/tex] .

The nth root of number m is represented by, =  [tex]\sqrt[n]{m}[/tex]

Here, we have to find expression for cube root of 1 + i

So, substitute n = 3 and m = 1 + i

We get,  

Cube root of , [tex]1 + i[/tex]  =   [tex]\sqrt[3]{1+i}[/tex]

Thus, Cube root of [tex]1+i[/tex] is represented by expression [tex]\sqrt[3]{1+i}[/tex] .
