Write x^2 + 6x -7 in the form (x+a)^2 +b where a and b are integers please
Answer:
[tex](x + 3) {}^{2} - 16[/tex]
Step-by-step explanation:
[tex] {x}^{2} + 6x - 7 = (x + 3) {}^{2} - (3) {}^{2} - 7 \\ = (x + 3) {}^{2} - 16[/tex]
The equation x^2 + 6x - 7 can be written in the form (x+a)^2 + b as (x + 3)^2 - 16 by completing the square.
Explanation:To solve this, we will complete the square for the polynomial x^2 + 6x - 7. The equation (x+a)^2 + b involves squaring a binomial (x+a) and adding a constant. Completing the square can convert x^2 + 6x - 7 to this form.
Step 1: Half of the coefficient of x is (6/2)=3 so a=3. Then we square a to get a^2 = 9.
Step 2: We adjust the original equation by subtracting and adding a^2 within it: (x^2 + 6x + 9) - 9 - 7.
Step 3: Simplify the equation to get (x + 3)^2 - 16, which is the form we desired.

Find the common ratio for the following sequence. 1/2, -1/4, 1/8, -1/16, ... - 2 - 2
Answer:
The common ratio for the given geometric sequence is -1/2.
Step-by-step explanation:
The common ratio in a geometric sequence is simply the number that multiplies one term to arrive at the next term. From the sequence given, we can let the common ratio be x and determine its value using any of the following set of equations;
1/2 * x = -1/4
-1/4 * x = 1/8
1/8 * x = -1/16
using the first equation;
1/2 * x = -1/4
we divide both sides by 1/2 to solve for x.
x = (-1/4)/(1/2)
x = -1/4 * 2
x = -1/2
Thus, the common ratio for the given geometric sequence is -1/2.
Answer:
Common ratio is -1/2
Step-by-step explanation:
Common ratio is the amount between each number in a geometric sequence.
It is called the common ratio because it is the same to each number.
Common ratio is the ratio between two successive numbers in a geometric sequence.
Common is a gotten by either division or multiplication.
Therefore in the case above
1/2 x -1/2 = -1/4 ......
-1/4 x -1/2 = 1/8 ......
1/8 x -1/2 = -1/16 ....etc
Therefore our common ratio is -1/2

The square of a number is three times the number itself. What is the number?
x^2 = x3
x^2 - 3x = 0
x(x - 3) = 0
x = 0 and x -3 = 0 or x = 3
x cannot equal zero, therefore the answer is three
The numbers that when squared equal to three times themselves are 0 and 3. This is found by solving the quadratic equation x² = 3x, which factors to x(x - 3) = 0.
To express this mathematically, we let 'x' represent the number, so the equation becomes x² = 3x. This is a quadratic equation that can be solved by rearranging the terms and factoring, resulting in x(x - 3) = 0. Applying the Zero Product Property, we have two potential solutions for x: 0 or 3. Therefore, the numbers that fit the condition are 0 and 3.
Write the point-slope form of the line that passes through (6, 1) and is perpendicular to a line with a slope of -3. Include all of your work in your final answer. Type your answer in the box provided or use the upload option to submit your solution
ANSWER
[tex]y-1= \frac{1}{3} (x- 6)[/tex]
EXPLANATION
We want to write the point-slope form of the line that passes through (6, 1) and is perpendicular to a line with a slope of -3.
The slope of this line is negative reciprocal of -3.
[tex]m = - \frac{1}{ - 3} = \frac{1}{3} [/tex]
The point-slope form is given by:
[tex]y-y_1=m(x-x_1)[/tex]
We substitute the point and the slope to get;
[tex]y-1= \frac{1}{3} (x- 6)[/tex]
Answer:
y - 1 = 1/3*(x - 6)
Step-by-step explanation:
point-slope form of a line:
y - y1 = m*(x - x1)
where x1 and y1 are the coordinates of the point included in the line and m is its slope.
Two lines are perpendicular when the multiplication of their slopes is equal to -1. In this case,
m*(-3) = -1
m = 1/3
Replacing this slope and the coordinates of point (6, 1) we get:
y - 1 = 1/3*(x - 6)

Find the measure of angle 1
Answer:
38°
Step-by-step explanation:
Angles in a triangle add up to 180° and opposite angles are equal, therefore 180°-104°=76°
76°÷2=38°
I think this is correct :)
Answer:
The correct answer is <1 = 38°
Step-by-step explanation:
From the figure we can see a parallelogram.
Opposite angles of a parallelogram are equal.
To find the measure of <1
From the figure we get <1 + <2 = <3 + <4
<1 = <2
<1 + <2 + <3 + <4 = 360 - (2 * 104)
= 360 - 208 = 152
<1 + <2 = 152/2 = 76°
<1 = <2 = 76/2 = 38°
Therefore measure of <1 = 38°

D.
15.97°, 81.89°, 82.14°
Answer:
A. 48.35°, 94.94°, 36.71°
Step-by-step explanation:
Given,
ABC is a triangle,
In which AB = 12 miles, BC = 15 miles and AC = 20 miles,
By the cosine law,
[tex]BC^2 = AC^2 +AB^2 -2\times AC\times AB\times cos A[/tex]
[tex]2(AC)(AB)cos A=AC^2+AB^2-BC^2[/tex]
[tex]\implies cos A = \frac{AC^2+AB^2-BC^2}{2(AC)(AB)}----(1)[/tex]
Similarly,
[tex]cos B = \frac{BC^2+AB^2-AC^2}{2(BC)(AB)}----(2)[/tex]
[tex]cos C = \frac{BC^2+AC^2-AB^2}{2(AC)(BC)}----(3)[/tex]
By substituting the values in equation (1),
[tex]cos A=\frac{20^2+12^2-15^2}{2(20(12)}=0.66458[/tex]
[tex]\implies m\angle A\approx 48.35^{\circ}[/tex]
Similarly, from equation (2) and (3),
[tex]m\angle B\approx 94.94^{\circ}[/tex]
[tex]m\angle C\approx 36.71^{\circ}[/tex]
Hence, Option 'A' is correct.

Mike biked 6 3/4 miles, and Noah biked 4 1/2 miles. How many times the length of Noah's bike ride was mike's bike ride? Please show the steps.
Thank you,
Answer:
1.5 times
Step-by-step explanation:
6.75/4.5 = 1.5
To find out how many times longer Mike's ride was than Noah's, you first need to convert the mixed fractions to improper fractions. Then you divide the length of Mike's ride by Noah's ride length. The result is 1.5, meaning Mike’s bike ride was 1.5 times longer than Noah’s.
Explanation:This problem falls under the category of division of fractions. The question is asking for how many times longer Mike's ride was than Noah's. In order to do this, we must divide the length of Mike's ride by the length of Noah's ride.
First, we convert the mixed fractions to improper fractions. Mike biked 6 3/4 = 27/4 miles, and Noah biked 4 1/2 = 9/2 miles.
To find how many times longer Mike's ride was than Noah's, we divide 27/4 by 9/2. This is equivalent to multiplying 27/4 by the reciprocal of 9/2 (which is 2/9).
When we perform this multiplication, we get (27/4) * (2/9) = (27 * 2) / (4 * 9) = 54 / 36. The result is 1.5, so this means Mike’s bike ride was 1.5 times longer than Noah’s bike ride.

For all values of x, which expression is equivalent to 9(2x+9)+2(2x+9)
Answer:
22x + 99
Step-by-step explanation:
Given
9(2x + 9) + 2(2x +9) ← factor out (2x + 9) from each term
= (2x + 9)(9 + 2)
= 11(2x + 9) ← distribute parenthesis
= 22x + 99
Here's two ways you can solve this exercise: you can expand the multiplications and sum like terms:
[tex]9(2x+9)+2(2x+9) = 18x+81+4x+18 = 22x+99[/tex]
Or you can factor the parenthesis:
[tex]9(2x+9)+2(2x+9) = (2x+9)(9+2) = 11(2x+9) = 22x+99[/tex]
The length of a rectangle is the width minus 5 units. The area of the rectangle is 36 units. What is the width, in units, of the rectangle
Answer:
The width of the rectangle is [tex]9\ units[/tex]
Step-by-step explanation:
Let
x----> the length of rectangle
y----> the width of rectangle
we know that
The area of rectangle is equal to
[tex]A=xy[/tex]
[tex]A=36\ units^{2}[/tex]
so
[tex]36=xy[/tex] ------> equation A
[tex]x=y-5[/tex] -----> equation B
substitute equation B in equation A and solve for y
[tex]36=(y-5)y[/tex]
[tex]y^{2}-5y-36=0[/tex]
Solve the quadratic equation by graphing
The solution is [tex]y=9\ units[/tex]
see the attached figure
therefore
The width of the rectangle is [tex]9\ units[/tex]
Answer: 9 units.
Step-by-step explanation:
Let x be the width of the rectangle .
Then, the length would be x-5.
Area of rectangle = Length x Breadth
[tex]=(x-5)x=x^2-5x[/tex]
Since , The area of the rectangle is 36 units.
[tex]\Rightarrow\ x^2-5x=36\\\\\Rightarrow\ x^2-5x-36=0\\\\\Rightarrow\ x^2-9x+4x-36=0\\\\\Rigtarrow\ x(x-9)+4(x-9)=0\\\\\Rightarrow\ (x-9)(x+4)=0\\\\\Rightarrow\ x=9 , -4[/tex]
But width cannot be negative , so width = x= 9 units
Hence, the width of the rectangle = 9 units.
