2x + 8 = 4x - 10 Given
2x + 8 - 2x = 4x - 10 - 2x Subtraction property of equality
8 = 2x - 10
8 + 10 = 2x - 10 + 10 Addition property of equality

Solution of the given equation 2x+8=4x-10 is x=9.
Solution of an equation are the values to the unknown variables that makes the equality in the equation true
Given equation is :
2x+8=4x-10, consider it as equation (1)
To solve this equation firstly, we isolate the terms which contain x in the LHS and the constant terms in RHS.
Then, the equation will become:
2x-4x = -10-8
Solving the LHS and RHS:
-2x = -18
Divide both the sides by -2, we get:
x = -18/(-2)
x = 9
That means x=9 satisfies the given equation.
Hence, x=9 is the solution of the given equation.

The vertex of this parabola is at -5, -2. when the x-value is 4, the y-value is 2. What is the coefficient of the squared expression in the parabola's equation
Answer:
4/81 = a
Step-by-step explanation:
The vertex form of a parabola is
y = a (x-h)^2 +k where (h,k) is the is the vertex
y = a (x- -5)^2 -2
y = a (x+5)^2 -2
Substituting the point into the equation
2 = a( 4+5)^2 -2
2 = a( 9)^2 -2
2 = a (81) -2
Add 2 to each side
4 = 81 a
Divide each side by 81
4/81 = a
Answer:
a=4/81

Enter the numerical coordinates of the vertices of quadrilateral ABCD in the table. (Point A has been done for you.) Then predict the numerical
coordinates of the vertices of quadrilateral A'B'C'D' as the figure translates four different ways: 7 units up, 1 unit down, 4 units to the right, and 3
units to the left.
9514 1404 393
Answer:
up: (-3, 5); down: (-3, -3); right: (1, -2); left: (-6, -2)
Step-by-step explanation:
As you know, the coordinates of a given point tell you the distance ...
(right, up)
So, a displacement 7 units up adds 7 to the second coordinate value:
A(-3, -2) ⇒ A'(-3, -2+7) = A'(-3, 5) . . . . 7 units up
Likewise, 1 unit down subtracts 1 unit from the second coordinate value:
A(-3, -2) ⇒ A'(-3, -3) . . . . 1 unit down
__
Similarly, left-right changes affect only the first coordinate. Displacements right are added; displacements left are subtracted.
A(-3, -2) ⇒ A'(-3+4, -2) = A'(1, -2) . . . . 4 units right
A(-3, -2) ⇒ A'(-6, -2) . . . . 3 units left

(20 points)
Answer:
option B
Step-by-step explanation:
7 sq rt 3 cannot be simplified
4 sq rt 6 cannot be simplified
sq rt 48 = (sq rt 12 · sq rt 4) = (sq rt 4 · sq rt 4 · sq rt 3) = 4 sq rt 3
sq rt 54 = (sq rt 9 · sq rt 6) = 3 · sq rt 6
combine each pair of like terms: (7 sq rt 3 + 4 sq rt 3) = 11 sq rt 3
(-4 sq rt 6 - 3 · sq rt 6) = -7 sq rt 6

3/10 x ? = 21/10
Answer:
7 , or 7/1
Step-by-step explanation:
Let ? = x. Set the equation:
(3/10)x = 21/10
Isolate the variable, x. Multiply 10/3 to both sides of the equation:
x * (3/10) * (10/3) = (21/10) * (10/3)
x = 21/10 * 10/3
Simplify the equation. Divide common factors from both the numerator and denominator, and then simplify:
x = (21 * 10)/(10 * 3)
x = (21/3) = 7/1 = 7
x = 7

Calculate the marked price of a sweater purchased at Rs. 1075 allowing 14% discount. ( please do proper answer )
Answer:
Rs. 1250
Step-by-step explanation:
The sweater is purchased at Rs. 1075
The discount is 14%
Let y represent the marked price of the sweater
y × 14% = 1075
y × (100-14)/100= 1075
y × 86/100= 1075
y ×0.86= 1075
0.86y= 1075
Divide both sides by the coefficient of y which is 0.86
0.86y/0.86 = 1075/0.86
y = 1250
Hence the marked price is Rs. 1250

2 triangles are shown. The first triangle has side lengths x, x, 50. The second triangle has side lengths 45, 45, 75. What value of x will make the triangles similar by the SSS similarity theorem? 1.5 20 30 67.5
Answer:
30
Step-by-step explanation:
yes I can tell what it is
The value of x that will make the two triangles similar by the SSS similarity theorem is: C. 30.
What is the SSS Similarity Theorem?According to the SSS similarity theorem, if all the three corresponding sides of two triangles are proportional or have the same ratio, then both triangles are similar.
If the two triangles are similar we would have:
75/50 = 45/x
Cross multiply and find x
x = (45 × 50)/75
x = 30
Thus, the value of x would be: C. 30.

Answer:
Answer:
Domain : R
Range : R
Step-by-step explanation:
The given function is or it can be written as y = 15x.
So, the function is valid for all real values of x and we will get the real value of y for each real value od x.
Hence, all the real numbers or R is the domain of the function.
And all the real numbers or R is the range of the given function. (Answer)
the domain is the set of x -values, the range is the set of y-values. I would have to say the domain is : R [ negative intinity, to infinity]. Equally, I would have to say the range is R [ Negative infinity, to infinity]
Step-by-step explanation:
Why, because no set is defined for either x or y.

Abby's curtain company is making curtains for a local hotel. She wants each curtain to be 48 inches long. At the fabric store, fabric is sold by the foot. If Abby's curtain company wants to make 55 curtains, how many feet of fabric will she need? 1 inch = 1 12 foot
Answer:
220 ft
Step-by-step explanation:
Given that:
Length of each curtain = 48 inches
Number of curtains required for Abby's curtain company = 55
Fabric of curtains is sold by the fabric store foot by foot.
Unit for conversion:
1 inch = [tex]\frac{1}{12}[/tex] foot
To find:
The fabric (in feet) needed by Abby.
Solution:
First of all, let us convert the length of each curtain (which is given in inches) to feet.
As per given hint:
1 inch = [tex]\frac{1}{12}[/tex] foot
48 inches = [tex]\frac{1}{12}[/tex] [tex]\times[/tex] 48 ft = 4 ft
So, length of one curtain is 4 ft.
Now, number of curtains required are 55.
Therefore, total length of curtains required can be found by multiplying the number of curtains with the length of one curtain.
Total length of curtain required = 55 [tex]\times[/tex] 4 = 220 ft
