Answer:
A
Step-by-step explanation:
Given
x = y² + 6y + 1
To complete the square
add/subtract ( half the coefficient of the y- term )² to y² + 6y
x = y² + 2(3)y + 9 - 9 + 1
= (y + 3)² - 8
The vertex form of the equation of a parabola is,
⇒ x = (y + 3)² - 8
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The standard form of the equation of a parabola is,
⇒ x = y² + 6y + 1.
Now, We can simplify as;
⇒ x = y² + 6y + 1
⇒ x = y² + 6y + 9 - 9 + 1
⇒ x = (y + 3)² - 8
Thus, The vertex form of the equation of a parabola is,
⇒ x = (y + 3)² - 8

Is the following equation Linear, Non-linear, or neither
5x +2(x3 - 9) = 132 + 8x?
Answer:
x = 50
Step-by-step explanation:
5x + 2(3x - 9) = 132 + 8x
5x + 6x - 18 = 132 + 8x
11x - 18 = 132 + 8x
11x - 18 = 8x + 132
11x - 18 + 18 = 8x + 132 + 18
11x = 8x + 150
11x - 8x = 8x - 8x + 150
3x = 150
3x ÷ 3 = 150 ÷ 3
x = 50

Step-by-step explanation:
The measure of two consecutive angles of a parallelogram are in the ration of 7:5. What is the measure of the obtuse angle of the parallelogram.
Consecutive angles in a parallelogram are supplementary angles which when added together equal 180 degrees.
The ratio is 7:5 so we would have:
7x + 5x = 180
Simplify:
12x = 180
Divide both sides by 12:
X = 15
So one angle is 7 x 15 = 105 degrees
The other angle is 5 x 15 = 75 degrees
An obtuse angle is an angle greater than 90 degrees.
The obtuse angle would be 105 degrees.

George is reading a book.On Monday he read 1/3 of the book. On Tuesday he reads three-tenths of the remaining pages. He has 35 pages left to read. How many pages are in the book
Answer:
Step-by-step explanation:
m=p/3
t=(3/10)(1-1/3)
t=(3/10)(2/3)=p/5
p-p/3-p/5=35
(15p-5p-3p)/15=35
7p/15=35
7p=525
p=75
So the book has 75 pages.
Find the area (in square feet) of a trapezoid with height h and bases b_1 and b_2. h = 6 in b_1 = 9 in b_2 = 12 in The area is _ square feet
Answer:
Area of the trapezoid = 90 square feet
Step-by-step explanation:
Area of a trapezoid with bases b₁, b₂ and height h is given by the formula,
Area of a trapezoid = [tex]\frac{1}{2}(b_1+b_2)h[/tex]
By substituting the given values in the formula,
Area = [tex]\frac{1}{2}(6+9)12[/tex]
= [tex]\frac{180}{2}[/tex]
= 90 square feet
Therefore, area of the trapezoid = 90 square feet

6⋅10 −2 6, dot, 10, start superscript, minus, 2, end superscript is how many times as large as 2 ⋅ 1 0 − 8 2⋅10 −8 2, dot, 10, start superscript, minus, 8, end superscript?
Answer:
6⋅10^ −2 is 3* 10^6 greater than 2 ⋅ 10^− 8
Step-by-step explanation:
Given the following expression
6⋅10^ −2 and 2 ⋅ 10^− 8
Taking their ratio
k = 6⋅10^ −2/2 ⋅ 10^− 8
k = 6/2 * 10^-2/10^-8
k = 3 * 10^{-2+8}
k = 3* 10^6
Hence 6⋅10^ −2 is 3* 10^6 greater than 2 ⋅ 10^− 8

Answer:
x = 35 , y = 72.5
Step-by-step explanation:
(a)
x and 35° are vertical angles and are congruent, then
x = 35
(b)
y. y and 35 lie on a straight line and sum to 180°, that is
y + y + 35 = 180
2y + 35 = 180 ( subtract 35 from both sides )
2y = 145 ( divide both sides by 2 )
y = 72.5
Answer:
y = 72.5 degrees
X = 35 degrees
Step-by-step explanation: A straight line is 180 degrees. The line with the two y degrees and the 35 degrees is a straight line, which is = 180 degrees. Because the y degrees are the same variable (y) they are equal degrees. All you need to do to find y is 180-35 =145. Divide that by 2 to find both y’s. 145 / 2 = 72.5. You can do the same for x, or realize that x and 35 are alternate interior angles, meaning they are the same measure: 35 degrees.
