Solve, by completing the square, x^2=22x-5, leave your answer in surd form
Answer:
a) The complete square form = ( x-11)² = 116
b) x = 11 + 2√29
Step-by-step explanation:
Step(i):-
Given equation x² = 22x -5
⇒ x² - 22x + 5 =0
⇒ x² - 2× 11 x + (11)² -(11)² + 5=0
⇒ ( x- 11)² -121 +5 =0
⇒ ( x-11)² = 116
The complete square form = ( x-11)² = 116
Step(ii):-
⇒ (x-11) = √116 = √29 ×√4
⇒ x-11 = 2√29
⇒ x = 11 + 2√29

Angel is saving all of his money for a ticket to Grad Bash. Before he started working, he had $7.50 in his bank account On Saturday, he works 5 hours and earns $42.50 On Sunday, he works 8 hours and earns $68,00
Which of the following functions models Angels savings?
Answer:
The second choice is correct. (f(x) = 8.50x+7.50)
Angel had +7.50 dollars to start off with and then worked 5 hours to get 42.50 dollars. This means, she earns 8 dollars 50 cents per hour, meaning that 8.50x would represent the total amount of money that she would earn from her job.

Answer:

Step-by-step explanation:
we know both triangles are congruent, so we can make an equation
3x+7=10x-7
take 3x from both sides
7=7x-7
14=7x
x=2
20-7=CAD
m<CAD is 13
The value of the angle CAD in the figure given is 13°.
So, the correct option is 1.
Given is a figure, we need to find the measure of the angle CAD,
To find the required measurement we will show the triangles ABD and ACD are congruent,
So, considering the Δ ABD and Δ ACD,
BD ≅ DC [marked in the figure]
∠B ≅ ∠C [all the right angles are ≅]
DA = DA [common in the both Δs]
Hence, Δ ABD ≅ Δ ACD by SSA rule.
We get, ∠CAD ≅ BAD by CPCTC.
Therefore,
3x + 7 = 10x - 7
Combining the like terms,
10x - 3x = 7 + 7
7x = 14
x = 2
Put x = 2 in ∠CAD = 3x + 7,
∠CAD = 3(2) + 7
∠CAD = 6 + 7
∠CAD = 13°
Hence, ∠CAD = 13°.

Isabelle wants to become an astronaut! She has decided that she will
spend 20% of her day studying. If she is awake for 15 hours each day, how
long is she spending studying?
Answer:
3 hours
Step-by-step explanation:
Assuming that when the problem says "day" it refers to the hours of wakeness. The problem is essentially asking to find 20% of 15.
First, convert 20% to decimal form. To do this, divide (20) by 100, this is because a percent is out of 100.
20 / 100 = 0.2
Now multiply the hours of wakeness by the percent as a decimal;
15 * 0.2 = 3
Isabelle spends 3 hours studying.
2x - 3y = 2, 4x + 7y = -9.
Step-by-step explanation:if you like it press thank you ❤❤❤

2x=2+3y
2x=2+3y

4x-7= -9
4x = -2 now lets check,4(-1) + 7(-1)= -9 or 2(-1)-3(-1)=2

Triangle QRS is rotated 180° about the origin. On a coordinate plane, triangle Q R S has points (negative 4, 1), (negative 4, 4), (2, 1). What are the coordinates of point S'?
Answer:
D. (2, -1)
Step-by-step explanation:
I took the test and got it right.
Triangle QRS is rotated 180° about the origin. On a coordinate plane, triangle Q R S has points (-4, 1), (-4, 4), (2, 1). So, the coordinates of point S will be (2, -1).
How does rotation by 90 degrees changes coordinates of a point if rotation is with respect to origin?Let the point be having coordinates (x,y).
If the point is in first quadrant:
Subcase: Clockwise rotation:
Then (x,y) → (y, -x)
Subcase: Counterclockwise rotation:
Then (x,y) → (-y, x)
If the point is in the second quadrant:
Subcase: Clockwise rotation:
Then (x,y) → (y, -x)
Subcase: Counterclockwise rotation:
Then (x,y) → (-y, x)
Triangle QRS is rotated 180° about the origin.
On a coordinate plane, triangle Q R S has points (-4, 1), (-4, 4), (2, 1).
So, the coordinates of point S will be (2, -1).

Write an
equation that represents the line.
Use exact numbers.
Given:
The graph of a line.
To find:
The equation of the line.
Solution:
From the given graph it is clear that the line passes through the points (0,2) and (3,-2). So, the equation of the line is:
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-2=\dfrac{-2-2}{3-0}(x-0)[/tex]
[tex]y-2=\dfrac{-4}{3}x[/tex]
Adding 2 on both sides, we get
[tex]y=-\dfrac{4}{3}x+2[/tex]
Therefore, the equation for the given line is [tex]y=-\dfrac{4}{3}x+2[/tex].
