If (x+42)+3x = 90 what is x
Answer:
X=12
Step-by-step explanation:
First, take the term out parenthesis being careful to manage the sign of individual term carefully :
x+42+3x=90
Next , subtract 42 from each side of the equation to isolate the x term while keeping equation balance :
x+42-42+3x=90-42
x+0+3x=48
x+3x=48
(1+3)x=48
4x=48
Now, Divide both side of equations by 4 to slove of x while keeping equation balance :
4x/4=48/4
x=12
Here,
(12+42)+3*12=90
54+36
90

Describe the transformations necessary to transform the graph of f(x) into that of g(x).
Using translation concepts, it is found that the transformations necessary to transform the graph of f(x) into that of g(x) are given as follows:
Reflection over the y-axis. Horizontal stretch by a factor of 2.Shift left 3 units.Reflection over the x-axis.Shift down 1 unit.What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
The original function f(x) is given by:
[tex]f(x) = \sqrt{x}[/tex]
The transformations are as follows:
Inside the domain, the function was multiplied by -1/2 and 3 was added. Hence the function was reflected over the y-axis, horizontally stretched by a factor of 2 and shifted left 3 units.Outside the domain, in the range, the function was multiplied by -1 and 1 was subtracted, hence the function was reflected over the x-axis and shifted down one unit.More can be learned about translation concepts at https://brainly.com/question/4521517

• How can you check whether a point is the solution to a system?
Answer:
In other words, the solution is the point where the two lines intersect. To verify whether a point is a solution to a system or not, we will either determine whether it is the point of intersection of two lines on a graph or we will determine whether or not the point lies on both lines algebraically

Answer:
141°
Step-by-step explanation:
An octagon has 8 sides and 8angles so the sum of its interior angles is: (8-2)×180= 1080°
5x+133+16+126+162-12+30=1080°
5x=625
x=125°
x+16=141°
Use the wave equation to find the speed of a wave given by y(x, t) = (2. 00 mm)[(20 m−1)x − (4. 0 s−1)t] 0. 5
The speed of the wave whose wave equation :
y(x,t) =[tex](2.00 mm)[(20 m^{-1} )x - (4.0 s^{-1} ) t]^{0.5}[/tex] is 0.20 m/s
speed = 0.20 m/s
What is the speed of wave?
The wave equation is a linear second-order partial differential equation which describes the propagation of oscillations at a fixed speed in some quantity y.
The wave equation is given by:
y(x,t) =[tex](2.00 mm)[(20 m^{-1} )x - (4.0 s^{-1} ) t]^{0.5}[/tex] .......................(1)
As we know that the standard form of wave equation is of the form is
On Comparing it with equation (1)
we have,
angular number, k=20
and, angular frequency, ω=4.0 rad/s.
Thus, the speed of the wave is
v=[tex]\frac{\omega}{K}[/tex]
=[tex]\frac{(4.0 rad/s) }{(20 m^{-1}) }[/tex]
=0.20 m/s
The speed of the wave of the wave equation
y(x,t) =[tex](2.00 mm)[(20 m^{-1} )x - (4.0 s^{-1} ) t]^{0.5}[/tex] is 0.20 m/s

What is the vertex of the quadratic function f(x) = (x-8)(x - 2)?
Answer:
The vertex is (5, -9).
Step-by-step explanation:
One way of approaching this problem consists of finding the roots. Seet the quadratic equal to zero and solve for x: {2, 8}.
The axis of symmetry is exactly halfway between 2 and 8: x = 5.
Now find the y-component of the vertex by evaluating f(5):
f(5) = (5 - 8)(5 - 2) = -9
The vertex is (5, -9). This is the minimum value of the function. The graph of this quadratic opens up.

Answer:
4π
Step-by-step explanation:
the area (A) of each shaded sector is calculated as
A = area of circle × fraction of circle
the angle subtended at the centre of each sector = 180° - 160° = 20°
then area of 2 sectors

The slope of the line containing the points (-2, 3) and (-3,1) is
a.02 b.1/2 c.0 -2/5
Step-by-step explanation:
the slope is always the ratio "y coordinate change / x coordinate change" when going from one point of the line to another.
so, when going from (-2, 3) to (-3, 1)
x changes by -1 (from -2 to -3).
y changes by -2 (from 3 to 1).
therefore, the slope is
-2/-1 = 2/1 = 2

One angle of an isosceles triangle measures 80°. What measures are possible for the other two angles?
Answer:
80 degrees and 20 degrees.
Step-by-step explanation:
Isosceles means two angles are the same. If one angle is 80 degrees that means another angle is 80 degrees. The sum of all angles is 180 degrees. 80 degrees + 80 degrees = 160 degrees. After you do that you subtract 160 from 180 to get 20 degrees.
