Answer:
(- 2, 1 ) and (1, 4 )
Step-by-step explanation:
Given the 2 equations
y = - x² + 5 → (1)
- x + y = 3 → (2)
Rearrange (2) expressing y in terms of x by adding x to both sides
y = x + 3 → (3)
Substitute y = x + 3 into (1)
x + 3 = - x² + 5 ( subtract - x² + 5 from both sides )
x² + x - 2 = 0 ← in standard form
(x + 2)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 1 = 0 ⇒ x = 1
Substitute these values into (3) for corresponding values of y
x = - 2 : y = - 2 + 3 = 1 ⇒ (- 2, 1 )
x = 1 : y = 1 + 3 = 4 ⇒ (1, 4 )

A gaming
console costs
$300 and has
8% tax. How
much is the tax?
$30 or $24?
Answer:
24
Step-by-step explanation:
8 percent of 300 is 24.
that should be right
Answer:
$24
Step-by-step explanation:
The tax is how much more you have to pay based on a percentage of the initial cost. The tax percent in this case is 8%. Since the console costs $300, we take 8% of $300 and charge it as the tax.
$300 * 8% = $300 * 0.08 = $24
If done by hand, move the decimal place on 0.08 to the left 2 times
0.08
00.8
008
This will give you 8. Multiply 8 by $300 which will give you $2400, next move the decimal to the right 2 times.
$2400.
$240.0
$24.00
Now you have $24

Answer
[tex]y = 28 \sin(\frac{\pi}{6} - \frac{2\pi}{3}) + 49[/tex]
Step by Step Explanation
Given
See attachment for table
Required
Determine the sinusoidal function
The sinusoidal function is represented as:
[tex]y = A \sin(Bx + C) + D[/tex]
Where
[tex]|A| = Amplitude[/tex]
And it is calculated as:
[tex]A = \frac{1}{2}[Highest - Least][/tex]
From the table:
Highest = 77 and Least = 21
So:
[tex]A = \frac{1}{2}[77 - 21][/tex]
[tex]A = \frac{1}{2}[56][/tex]
[tex]A = 28[/tex]
B is calculated as:
[tex]Period = \frac{2\pi}{B}[/tex]
The period is 12 i.e. 12 months
So:
[tex]\frac{2\pi}{B} = 12[/tex]
[tex]B = \frac{2\pi}{12}[/tex]
[tex]B = \frac{\pi}{6}[/tex]
C is calculated as:
[tex]\frac{C}{B} = -4[/tex]
[tex]C = -4 * B[/tex]
[tex]C = -4 * \frac{\pi}{6}[/tex]
[tex]C = -2 * \frac{\pi}{3}[/tex]
[tex]C = -\frac{2\pi}{3}[/tex]
Lastly, D is calculated as:
[tex]D = Least + A[/tex]
So:
[tex]D =21 + 28[/tex]
[tex]D=49[/tex]
So, the function is:
[tex]y = A \sin(Bx + C) + D[/tex]
[tex]y = 28 \sin(\frac{\pi}{6} - \frac{2\pi}{3}) + 49[/tex]
Answer:
y=28 sin (pi/6 t - 7pi/6)+49

rigid transformations that will map the copied triangle to your original triangle. In the table, note the angles of rotation, lines of reflection, and
distances moved.
Answer:
Step
1 | Translate △DEF 7 units up.
2 | Translate △DEF 6 units to the left.
This is word by word so you may want to change it up a bit. Have a great day.
Step-by-step explanation: On PLATO, you may provide and record fewer steps. The answer will vary but may resemble an answer based off the mapping of △DEF to △ABC.

an electrician charges a $25 fee for a repair plus $15 per hour. Write an equation to model the total cost Y of a repair that takes X hours
find value of X in cos(3x-30°)=sin(7x+50°)
Answer:
7
Step-by-step explanation:
Given the expression
cos(3x-30°)=sin(7x+50°)
In trigonometry cosx = sin(90-x)
Hence
Cos(3x-30) = sin(90-(3x-30))
Cos (3x-30) = sin(90-3x+30)
Cos (3x-30) = sin(120-3x)
Substitute into the expression above
Sin(120-3x) = sin(7x+50)
120-3x = 7x+50
Collect like terms
-3x-7x = 50-120
-10x = -70.
x = 70/10
x = 7
Hence the value of x is 7

Sammy made her uncle a garden. The width is 6 5 7 ft and the length is 7 3 5 ft. What is the area of the garden?
Answer:
482895ft^2
Step-by-step explanation:
Given data
Width= 657ft
Length= 735ft
We know that area A
A= Length* Width
A=657*735
A= 482895ft^2
Hence the area is 482895ft^2

2x + 3y = -6
2x + 3y = 6
y= -2/3x - 2
v= 2/3x - 2
Answer:
A. 2x + 3y = -6
Step-by-step explanation:
[tex](-3,0) (0,-2)[/tex]
[tex]slope:\frac{-2-0}{0+3} =\frac{-2}{3}[/tex]
[tex]y-0=\frac{-2}{3} (x+3)[/tex]
[tex]3y=-2x-6[/tex]
[tex]3y+2x+6=0[/tex]
[tex]2x+3y=-6[/tex]

Ms. Smith and Mr. Roberts are running a race. Ms. Smith runs 8, 305 feet. Mr. Roberts runs 2 miles. How many feet further does Mr. Roberts run? (Reminder: 1 mile = 5,280 feet)
Answer:
Mr. Roberts runs 2,255 more feet then Ms. Smith.
Step-by-step explanation:
So I took 5,280 + 5,280 = 10,560 so now I can just take Ms. Smith's 8,305 and subtract it from 10,560 which gave me 2,255 so Mr. Roberts runs 2,255 more feet then Ms. Smith.
