Answer:
2x - 4 = 16
Step-by-step explanation:
'the difference' shows that its subtraction so u have to put a - in the equation
'double' means 2 and since you dont know the value of 'a number' you replace it with a variable like x. combine them and you get 2x
so far it should look like 2x -
4 is equal to 4 so just put a 4 in front of the subtraction sign
it'll look like 2x - 4 now
'is 16' basically means is equal to 16 so now ur equation should look like:
2x - 4 = 16
if you wanted to solve that u could add 4 to both sides then divide both sides by 2 and get x = 10
Answer:
x = 10
Step-by-step explanation:
2x - 4 = 16
2x = 20
x = 10

the graph below represents a linear function. which of the following equations models the linear graph above? please answer and explain why you chose the answer. i will mark you brainliest
D. Y= 4/3 (x)+4
The first step i did was finding C for the standard form equation of a linear function which is:
y=mx+c
Finding C is easy because C is simply the y-intercept(The point that crosses the y axis) which we can see from the graph is 4.
That allowed me to isolate possible answers of B and D because they contain a C which is equal to 4.
To determine which equation it was, i substituted an X coordinate to see if i got the correct Y coordinate from the graph.
Lets try B first and substitute the coordinate -3:
3/4 ×(-3)+4=1.75
As we see thats incorrect because the coordinate on the graph is (-3;0).
So we can conclude it is not b, however lets try D.
4/3 (-3)+4=0.
We see that this equation gives us the correct answer.
So therefore the correct equation is D
4/3 (x)+4
WHICH EXPRESSION IS EQUIVALENT TO 3(x-2)
The expression 3(x-2) is equivalent to 3x - 6.
When you distribute the 3 to the term inside the parentheses, you multiply 3 by x and by -2, resulting in 3x - 6.
This is because the distributive property states that for any real numbers a, b, and c, the expression a(b+c) is equivalent to ab + ac. In this case, we have a = 3, b = x, and c = -2, so we can apply the distributive property and get 3x - 6.
You can also think of it as 3 multiplied by (x-2)
3x - 32 = 3x - 6

1) Evaluate the integral taking omega is the triangle formed by the x-axis 2y=x and x=2 (6e^(x^2))
2) Find the volue of the solid bounded by the coordinate planes and (1/3)x+(1/2)y+(1/4)z=1
The volume of the solid is 4π([tex]\frac{19}{6}[/tex]) and the integral of the f(x) , the line 2y=x, and x=2 is 3([tex]e^{4}[/tex] -1).
What is integral ?
An integral is a mathematical concept that is used to calculate the area under a curve or the total amount of change in a variable over a certain interval.
1)The first step is to find the intersection of the lines 2y=x and x=2. They will intersect at (2,1).
The second step is to find the intersection of the lines 2y=x and x=0. They will intersect at (0,0).
The third step is to find the integral over the region.
∫∫ (6e^(x^2))dxdy = ∫[0,2] (6e^(x^2))dx ∫[0,x/2] dy = ∫[0,2] (6e^(x^2))dx (x/2) = [3e^(x^2)] at [0,2] = 3e^(4) - 3e^(0) = 3(e^4 -1).
2)To find the volume of this solid, we can use the method of cylindrical shells.
we can find the function of the surface (1/3)x+(1/2)y+(1/4)z=1
by using cylindrical coordinates:
x = rcosθ , y = rsinθ , z = z
and substitute them in the equation (1/3)x+(1/2)y+(1/4)z=1
(1/3)rcosθ+(1/2)rsinθ+(1/4)z=1
(1/3)r(cosθ+2sinθ)+(1/4)z=1
z = 4(1-(1/3)r(cosθ+2sinθ))
V = ∫∫∫ 4(1-(1/3)r(cosθ+2sinθ)) rdrdθdz = 4π ∫[0,3] (1-(1/3)r(cosθ+2sinθ)) r^2 dr = 4π ∫[0,3] (1-r+(2/3)r^2) dr = 4π(3 - (3/2) + (2/3)) = 4π(19/6).
Hence , The volume of the solid is 4π([tex]\frac{19}{6}[/tex]) and the integral of the f(x) , the line 2y=x, and x=2 is 3([tex]e^{4}[/tex] -1).

find f
f '(t) =20/1+t^2 f(1) = 0
If f '(t) =20/1 + t2 f(1) = 0, f is f(x) = 20tan⁻¹(t) - 5π.
Integrals are the values of the function seen by the process of integration.
The procedure of getting f(x) from F (x) is called integration.
Given f '(t) = 20/ 1 + t2 and f(1) = 0
We know that by definition of the integral of tan⁻¹(x) = 1/1 + t2
f '(t) = 20 / 1 + t2 = 20(1/ 1 + t2)
Integrate on both sides, we get
f(t) = 20tan⁻¹(t) + c
f(1) = 0; f(1) = 20tan⁻¹(1) + c = 0
c = -20(π/4) = -5π.
Therefore, f(x) = 20tan⁻¹(t) -5π.
If f '(t) =20/1 + t2 f(1) = 0, f is f(x) = 20tan⁻¹(t) - 5π.

Decrease 120% by 15%
By simply dividing the reduced value by 12, the value of 120 decreases by 12%, yielding a percentage drop of 102.
what is percentage ?In mathematics, a ratio or number expressed as a fraction of 100 is called a percentage. Also occasionally used are the acronyms "pct.," "pct," and "pc." However, the percentage symbol "%" is widely used to represent it. The % quantity is dimensionally empty. Basically, percentages are fractions when the denominator is 100. A percent symbol (%) should be placed next to a number to indicate that it is a percentage. For instance, you score a 75% on a test if you properly answer 75 out of 100 questions (75/100). When calculating percentages, multiply the result by 100 after dividing the amount by the total. By multiplying (value/total) by 100%, the percentage is determined.
given
The value of the percentage decrease
= · 120 - (15% × 120)
= 120 - 15% × 120
= 85 ÷ 100 × 120
= 85 × 120 ÷ 100 = 102
You may calculate the percentage drop by simply dividing the lowered value by the original value and multiplying the result by 100.
In this case, Reduced Value equals Original Value - New Value.
By simply dividing the reduced value by 12, the value of 120 decreases by 12%, yielding a percentage drop of 102.

_____ 1 _____
The missing coordinates of given vectors a, b, c, d, and e are 0,0,0, -0.8, and 0. Then, the vectors are [tex]\vec{u}=\left[\begin{array}{ccc}-0.6\\0.8\\0\end{array}\right][/tex], [tex]\vec{v}=\left[\begin{array}{ccc}0\\0\\1\end{array}\right][/tex], and [tex]\vec{w}=\left[\begin{array}{ccc}-0.8\\-0.6\\0\end{array}\right][/tex]
We refer to two vectors as being orthogonal if they are perpendicular to one another. So these vectors' dot product will be zero. Let the given three vectors be [tex]\vec{u}[/tex], [tex]\vec{v}[/tex], and [tex]\vec{w}[/tex]. And the unknowns be a, b, c, d, and e.
Then, the vectors are written as
[tex]\vec{u}=\left[\begin{array}{ccc}-0.6\\0.8\\a\end{array}\right][/tex], [tex]\vec{v}=\left[\begin{array}{ccc}b\\c\\1\end{array}\right][/tex], and [tex]\vec{w}=\left[\begin{array}{ccc}d\\-0.6\\e\end{array}\right][/tex]
First, take [tex]\vec{u}[/tex] and consider unit length, we get,
[tex]1=\sqrt{(-0.6)^2+(0.8)^2+a^2}\\1=1+a^2\\a=0[/tex]
For [tex]\vec{v}[/tex], we get,
[tex]1=\sqrt{(b)^2+(c)^2+1^2}\\1=1+b^2+c^2\\b=0\;\text{and}\;c=0[/tex]
We know that [tex]\vec{w}[/tex] is orthogonal to both vectors, then,[tex]\vect{w}\cdot{\vec{v}=0[/tex]. Substituting, the values of [tex]\vec{v}[/tex] and [tex]\vec{w}[/tex], we get,
[tex]\begin{aligned}\langle d, -0.6, e\rangle \;\cdot\;\langle 0, 0, 1\rangle&=0\\e&=0\end{aligned}[/tex]
Also, [tex]\vect{u}\cdot{\vec{w}=0[/tex], Substituting, the values of [tex]\vec{u}[/tex] and [tex]\vec{w}[/tex], we get,
[tex]\begin{aligned}\langle -0.6, 0.8, 0\rangle \;\cdot\;\langle d, -0.6, e\rangle&=0\\-0.6d-0.48+0&=0\\-0.6d&=0.48\\d&=-0.8\end{aligned}[/tex]

The value of a and b for the given quadrilateral to be a parallelogram is a = 16 and b = 4.
What is parallelogram?A quadrilateral having two sets of parallel sides is referred to as a parallelogram. In a parallelogram, the opposing sides are of equal length, and the opposing angles are of equal size. Additionally, the interior angles that are additional to the transversal on the same side. 360 degrees is the sum of all interior angles.
A parallelepiped is a three-dimensional shape with parallelogram-shaped faces.
We know that the opposite sides of a parallelogram are equal in length so we can equate the two sides as follows:
For a:
2a + 6 = 3a -10
Isolate the value of a by moving all the values having a to one side:
2a + 6 = 3a -10
3a - 2a = 6 + 10
a = 16
For b:
6b - 3 = 5b + 1
Isolate the value of b by moving all the values having b to one side:
6b - 3 = 5b + 1
6b - 5b = 1 + 3
