Which table contains only values that satisfy the equation
y = 0.25x + 8?
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.

2(x + 0.7) = 6(x – 0.8) well what i got for this is 2x + 1.4 = 6x - 4.8 -2 -2 1.4 = 4x - 4.8 +4.8 +4.8 so i do i finish this equation i need the answer how do i finish this Equation?
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.
this is due in an hour so i’d appreciate any help. :))

A tunnel has a semicircular cross-section
and a diameter of 10 m. If the roof of a bus
just touches the roof of the tunnel when
the bus is 2 m from one side, how high is
the bus?
Answer:
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.

Which expression represents a cube root of 1 + I?
Answer:
D (I think!!)
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] .

Here are 36 carpenters on a construction crew. On a certain day, 29 carpenters were present. Which proportion can be used to determine the percent of carpenters that were present?
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%

Which set of points includes all of the solutions for y = negative three halves times x plus two?
line going through 0 co
(x, y) for all real numbers
(x, negative three halves times x plus two) for all real numbers
(−2, 5), (0, 2), and (4, −4)
(−4, 8), (−2, 5), (0, 2), (2, −1), (4, −4)
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.

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).
