What real value or values of x satisfy the equation x−2=√x
Answer:
[tex]x=1,\:x=4[/tex]
Step-by-step explanation:
[tex]x-2=\sqrt{x}\\\\(x-2)^2=x\\\\x^2-4x+4=x\\\\x^2-5x+4=0\\\\(x-1)(x-4)=0\\\\x=1,\:x=4[/tex]
x=1 and x=4 are real value or values of x satisfy the equation x−2=√x
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
Equation is x−2=√x
We need to find for which values of x satisfy the equation.
x−2=√x
Take square on both the sides
(x-2)²=√x²
We know the algebraic identity
(a-b)²=a²+b²-2ab
(x-2)²=√x²
x²+2²-2(2)x=x
x²+4-4x=x
x²+4-4x-x=0
x²-5x+4=0
x²-4x-x+4=0
x(x-4)-(x-4)=0
(x-1)(x-4)=0
x-1=0
x=1
x-4=0
x=4
Hence, x=1 and x=4 are real value or values of x satisfy the equation x−2=√x

At the movies, Fred and his five friends bought some snacks. They each bought a small popcorn for $3.25. They bought 3 bags of candy to share for $2.50. 2 of the boys bought a soda for $3. Write the expression that you can use to find out how much money they spent at the movies on snacks.
3.25 • 5 + 2.50 • 3 + 2 • 3 = x
16.25 + 7.50 + 6 = x
29.75 = how much they spent all-together

The midpoint of AB is M(2, 0) If the coordinates of A are (-3, 3) what are the coordinates of B
Answer:
(7, -3)
Step-by-step explanation:
If M is the midpoint you can use the same translation from A to M as M to B.
The movement from A to M is 5 units up and 3 units left, or (x+5, y-3). If we do the same movement to point M (Which is (2) +5, (0) -3) we will get (7, -3).
Answer:
the coordinates of B is B(7,-3)
Step-by-step explanation:
Solution,
Here, M(2,0) is the midpoint of a line segment joining the points A(-3,3)
and B(a,b)
Let,
(x,y)=(2,0)
(x1,y1)=(-3,3)
(x2,y2)=(a,b)
Now,
Using midpoint formula

The figure shows a rectangle ABCD where the diagonals AC and BD intersect at E.
Given that BEC = 52°, find
(I) ADB
(ii) ACD
Answer:
(i) 64°
(ii) 26°
Step-by-step explanation:
Answer:
(i) m<ADB = 64°
(ii) m<ACD = 26°
Step-by-step explanation:
I use this to mean the measure of angle ADC: m<ADC
(i)
m<BEC = 52°
<DEA and <BEC are vertical angles, so they are congruent.
m<DEA = m<BEC = 52°
Polygon ABCD is a rectangle. When the diagonals, AC and BD, of a rectangle are drawn, 4 triangles are formed. Each two opposite triangles are congruent, and all 4 triangles are isosceles.
Triangle ADE is an isosceles triangle with congruent sides ED and EA. That makes opposite angles ADB and DAC congruent. Also the sum of the measures of the angles of a triangle is 180°.
m<ADB + m<DAC + m<DEA = 180°
m<ADB = m<DAC; m<DEA = 52°
2m<ADB + 52° = 180°
2m<ADB = 128°
m<ADB = 64°
(ii)
Angles DEC and BEC form a linear pair. That means the angles are supplementary, and the sum of their measures is 180°.
m<DEC + m<BEC = 180°
m<DEC + 52° = 180°
m<DEC = 128°
Triangle DEC is an isosceles triangle with congruent sides ED and EC. That makes opposite angles ACD and BDC congruent.
m<ACD + m<BDC + m<DEC = 180°
2m<ACD + 128° = 180°
2m<ACD = 52°
m<ACD = 26°

The stock of Company A gained 3.5% today to $16.56 . What was the opening price of the stock in the beginning of the day?
well, the opening price was "x", which oddly enough is the 100%, however during the trading of the day the company gained 3.5%, so that'd be 100% + 3.5% = 103.5%, and we know that that is 16.56, so
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} x&100\\ 16.56&103.5 \end{array}\implies \cfrac{x}{16.56}=\cfrac{100}{103.5}\implies 103.5x=1656 \\\\\\ x=\cfrac{1656}{103.5}\implies x=16[/tex]

Which step could be used to help isolate the variable in the following equation? 5. 6j – 0. 12 = 4 1. 1j.
For the expression 5.6j - 0.12 = 4 + 1.1j, the value of variable j is 0.92.
What is the property of equality?
The operations of addition, subtraction, multiplication, and division do not change the truth value of any equation is called the property of equality.
The given expression is 5.6j - 0.12 = 4 + 1.1j.
To solve the above expression, we will use the following steps.
Step 1:
By the subtraction property of equality, subtract 1.1j on both sides. We get the expression,
[tex]5.6j - 0.12 -1.1j = 4 + 1.1 j - 1.1 j[/tex]
[tex]4.5 j -0.12 = 4[/tex]
Step 2:
By the addition property of equality, add 0.12 on both sides. We get the expression,
[tex]4.5j -0.12 + 0.12 = 4 + 0.12[/tex]
[tex]4.5 j = 4.12[/tex]
Step 3:
By the division property of equality, divide the above expression by 4.5. We get the expression,
[tex]\dfrac {4.5j}{4.5 }= \dfrac {4.12}{4.5}[/tex]
[tex]j = \dfrac {4.12}{4.5}[/tex]
[tex]j = 0.92[/tex]
Hence we can conclude that the value of variable j is 0.92.

Answer:
Constant of proportionality: [tex]\frac{1}{3}[/tex]
Equation: [tex]y=\frac{1}{3}x[/tex]
Step-by-step explanation:
The constant of proportionality is the ratio between y and x, according to the following formula
constant of proportionality = k = y/x
Take the given pairs and replace the data.
1.
[tex]k=\frac{\frac{2}{3}}{2}[/tex]
[tex]k = \frac{1}{3}[/tex]
2.
[tex]k = \frac{1}{3}[/tex]
3.
[tex]k=\frac{\frac{10}{3}}{10}[/tex]
[tex]k = \frac{1}{3}[/tex]
4.
[tex]k = \frac{4}{12}[/tex]
[tex]k = \frac{1}{3}[/tex]
As you can see, the constant is the same for all the pairs.
constant of proportionality = [tex]\frac{1}{3}[/tex]
Now, in order to know the equation make a graph of the given data.
The graph is in the picture
Since it is a line, use the equation of the line in point slope form
[tex]y- { y }_{ 1 } = m \left( x- { x }_{ 1 } \right)[/tex]
where (x1, y1) = any pair of the data
m = slope = constant of proportionality
Replace the data in the equation
[tex]y-1 = \dfrac{ 1 }{ 3 } \left( x-3 \right)[/tex]
Use the distributive property to multiply [tex]\frac{1}{3}[/tex] by x - 3
[tex]y-1=\frac{1}{3}x-1[/tex]
Add 1 to both sides
[tex]y = \dfrac{ 1 }{ 3 } x-1+1[/tex]
Add −1 and 1 to get 0
[tex]y=\frac{1}{3}x[/tex]
or
[tex]y=\frac{x}{3}[/tex]
