Solve the equation, 2x + 1 = 3, for x. Which of the following properties of equality did you apply? Question 11 options: A) Addition and division B) Addition and multiplication C) Subtraction and multiplication D) Subtraction and division
Answer:
D
Step-by-step explanation:
2x+1=3
-1 on both sides: 2x=2, then divide by two. You get x=1
For this you would use D, subtraction and division
Answer:
x = 1
D) Subtraction and Division
Step-by-step explanation:
2x + 1 = 3
(2x + 1) - 1) = (3) - 1 ←
2x = 2
(2x)/2 = (2)/2 ←
x = 1
In the places where I put the arrows is where I applied the properties. I used subtraction and division to solve.

An isosceles triangle has two angle measurements of 80 and 50 degrees. Could more than one triangle be drawn that fits these conditions? Explain.
Answer:
Step-by-step explanation:
In an isosceles triangle, the base angles are equal. This also means that two sides of the triangle are equal in length. Since the sum of the angles in a triangle is 180 degrees, it means that the third angle of the given triangle is
180 - (80 + 50) = 50 degrees
Therefore, the base angles of the isosceles triangle are 50 degrees each. For more triangles with these conditions to be drawn, only the lengths of the equal sides can be increased or decreased. This would in turn increase the length of the third side. Therefore, isosceles triangles of the same angles but different sizes can be drawn.

TABLE BELOW USED FOR QUESTION (1st pic)
Find the relative frequencies of students by COLUMN for the previous table. Round to the nearest hundredth if necessary. (2nd pic)
Answer:
like fishing dislike fishing
male 0.62 0.38
female 0.38 0.62
Step-by-step explanation:
To compute column relative frequencies you have to divide the value of each column by the total of each column, as follows:
like fishing dislike fishing
male 35/56 = 0.62 15/39 = 0.38
female 21/56 = 0.38 24/39 = 0.62

The product of 4 and the difference of x and 3 is 54
Answer:
x = 16.5
Step-by-step explanation:
the original equation is: 4(x - 3) = 54
first divide both sides by 4: x - 3 = 13.5
finally add both sides by 3: x = 16.5

Answer:
You would need $23.87.
Step-by-step explanation:
Divide $20.46 by 6 which equals $3.41. Multiply $3.41 by 7 and you get $23.87.
Answer:
You would need $23.87
Step-by-step explanation:
Cost for 6 books is 20.46
Finding the unit cost:
the cost of one single book will be amount for 6books ÷ 6
= 20.46 ÷ 6
= 3.41
We need to find the cost of 7 books so now that we know it for one book, we multiply that amount by 7
Therefore,
3.41 x 7
= 23.87 dollars
Find the domain of the function.
y = [tex]\sqrt{x} + 1[/tex]
Answer:
[0, infinity)
Step-by-step explanation:
A square root can only use positive numbers, otherwise it becomes imaginary. A function needs to be real to output real values. Therefore, the domain is everything from 0 onwards.

Step-by-step explanation:
Given the expression: [tex]x^3 \cdot x^5[/tex]
We are required to express it in simplified exponential notation.
We apply the addition law of indices below.
Given two expressions [tex]a^x$ and a^y[/tex] with same base a, then: [tex]a^x \cdot a^y=a^{x+y}[/tex]

Step-by-step explanation:
Identify the equivalent expressions of 4(2x + x – 3) – 3x + 3 by substituting x = 2 and x = 3.
Answer:
9
18
Step-by-step explanation:
x = 2:
4(4 + 2 - 3) - 6 + 3 = 12 - 6 + 3 = 9
x = 3:
4(6 + 3 - 3) - 9 + 3 = 24 - 9 + 3 = 18
Answer:
9x -9
9(x - 1)
4(3x-3) - 3x + 3
Step-by-step explanation:
4(2x + x-3) - 3x + 3
Combine like terms
4(3x-3) - 3x + 3
Distribute
12x -12 -3x+3
Combine like terms
9x -9
Factor out 9

In circle A shown below, the measure of ∠BAD is 148°: Circle A with angle BAD measuring 148 degrees; points B, C, D lie on Circle A. If m Arc BC is 96°, what is m Arc CD ?
Answer:
52°
Step-by-step explanation:
In the figure attached, Circle A is shown. There we can see that:
∠BC + ∠CD = ∠BAD
We know that Arc BC measures 96° and arc BAD measures 148°. Replacing this data into the equation and solving for Arc CD, we get:
96° + ∠CD = 148°
∠CD = 148° - 96°
∠CD = 52°
Answer:
The answer is 52

Simplify 8x^4/x^3+7x^4 and Find the excluded values
So first what we do is we need to get the excluded values. So to get them we have: 8x^4/x^3+7x^4.
Lets factor out the second part. x^3+7x^4 = (x^(3/4)+7x))^4
So then we get 8x^4/(x^(3/4)+7x)^4
8x^4/(x^(3/4)+7x)^4
Work this out for me
Answer:
x = 129
Step-by-step explanation:
x and 51 are same- side exterior angles and supplementary, thus
x = 180 - 51 = 129
Answer:
19degree I think
Step-by-step explanation:
the sum of each angle on the straight line is 180 degree so if you want to find x you needed to subtract 180degree-51 degree then you will get the answer

What are the coordinates of the vertex of a parabola whose equation is y−4=2(x+7)2 ?
Question 5 options:
a) (7, -4)
b) (-7, 4)
c) (4, -7)
b) (-4, 7)
The coordinate of the vertex of the parabola y - 4 = 2(x+7)² is (-7,4)
The coordinate of the vertex?The equation of the parabola is given as:
y - 4 = 2(x+7)²
Add 4 to both sides
y = 2(x+7)² + 4
A parabola is represented as:
y = a(x- h)² + k
Where, the vertex is:
vertex = (h,k)
By comparison, we have:
Vertex = (-7,4)
Hence, the coordinate of the vertex is (-7,4)
