HINT: Try graphing your equations or multiplying the cost equation by 4.
I NEED HELP FOR ALL 4 OF THOSE! THAT’S IT! PLZZZZ AND TY
Answer:
Step-by-step explanation:
Given equation of a straight line is,
y = -4 - 2x
Domain of the line (x) → {-3, -2, -1, 0, 1}
Therefore, range for the given set of domain will be,
Range (y) → {2, 0, -2, -4, -6}
[By substituting the value of x in the given equation we get the value of y]
Set of scatter points are,
(-3, 2), (-2, 0), (-1, -2), (0, -4), (1, -6)
Now we plot these points to get the discrete graph as attached.

Morning Donuts has 92 donuts for sale, including 8 jelly-filled donuts. What is the probability that a randomly selected donut will be a jelly-filled donut? Write your answer as a fraction or whole number.
Answer:
Probability [selected donuts a jelly-filled donut] = 2 / 23
Step-by-step explanation:
Given:
Total number of donuts = 92
Number of jelly-filled donuts = 8
Find:
Probability [selected donuts a jelly-filled donut]
Computation:
Probability [selected donuts a jelly-filled donut] = Number of jelly-filled donuts / Total number of donuts
Probability [selected donuts a jelly-filled donut] = 8 / 92
Probability [selected donuts a jelly-filled donut] = 2 / 23

Naomi used a rectangle, a square, and a right triangle to form the following figure.
What is the area of the shaded region of the figure in
eters?
A-120 cm2
B-102 cm2
C-18 cm2
D-9 cm2
Answer:
102 cm2
Step-by-step explanation:
First you want to find the area of the entire rectangle by multiplying the 2 sides.
20cm x 6cm = 120
Then you want to find the area of the other two shapes (in this case the square and triangle). Also use the other sides to find the lengths of the triangle.
Square = 3 x 3 = 9
triangle = 6 x 3 = 18 / 2 = 9
So then all you have to do is subtract the squares and triangles area from the total rectangle.
120 - (9 + 9)
120 - 18
102 cm2

Answer:
The amount of money they will spend at the restaurant is $35.16
Step-by-step explanation:
From the information given in the question, we have;
The amount Jessica, Genesis, and Violet received as bill at the restaurant, X = $29.30
The amount they wished to leave as tip, T = 20% (of the bill)
Therefore, the amount of money they will spend at the restaurant, 'A', is given as follows;
A = X + T
T = 20% of X = 20/100 × X = 0.2·X
∴ A = X + 0.2·X = 1.2·X
X = $29.30
A = 1.2·X = 1.2 × $29.30 = $35.16
The amount of money they will spend at the restaurant, A = $35.16

what the slope and the y intercept for-12x+4y=-8
Answer:
slope is -3
y-intercept is -2
Step-by-step explanation:
put into slope-intercept form which is y = mx + b where 'm' is slope and 'b' is the y-intercept
12x + 4y = -8
4y = -12x - 8
y = -12/4x - 8/4
y = -3x - 2 (simplified)
The length of rectangle is represented by 8x - 3. The width of the rectangle is represented by 2x. The perimeter is 34 inches. Which equations represent the perimeter? Choose all of the correct answers.
Answer: 20x-6 = 34
Step-by-step explanation:
Given: The length of rectangle is represented by 8x - 3.
The width of the rectangle is represented by 2x.
The perimeter is 34 inches.
Perimeter of rectangle = 2 (length + width)
Perimeter of rectangle = 2 (8x-3+2x)
Perimeter of rectangle = 2 (10x-3)
Perimeter of rectangle = 20x-6
Thus , the required equation that represent the perimeter: 20x-6 = 34

A cosine function has a period of 4, a maximum value of 20, and a minimum value of 0. The function is not a reflection of its parent function over the x-axis.
Which function could be the function described?
Answer:
○ [tex]\displaystyle f(x) = 10cos\:\frac{\pi}{2}x + 10[/tex]
Step-by-step explanation:
[tex]\displaystyle \boxed{f(x) = 10sin\:(\frac{\pi}{2}x + \frac{\pi}{2}) + 10} \\ \\ y = Asin(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow 10 \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \hookrightarrow \boxed{-1} \hookrightarrow \frac{-\frac{\pi}{2}}{\frac{\pi}{2}} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{4} \hookrightarrow \frac{2}{\frac{\pi}{2}}\pi \\ Amplitude \hookrightarrow 10[/tex]
OR
[tex]\displaystyle y = Acos(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow 10 \\ Horisontal\:[Phase]\:Shift \hookrightarrow 0 \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{4} \hookrightarrow \frac{2}{\frac{\pi}{2}}\pi \\ Amplitude \hookrightarrow 10[/tex]
The cosine graph in the photograph on the right is the OPPOCITE of the cosine graph in the photograph on the left, and the reason for this is because of the negative inserted in front of the amplitude value. Whenever you insert a negative in front of the amplitude value of any trigonometric equation, the whole graph reflects over the midline. Keep this in mind moving forward. Now, with all that being said, no matter how far the graph shifts vertically, the midline will ALWAYS follow.
**Moreover, both graphs have the same maximum and minimum value, but we are looking for the equation that will not reflect over the midline of [tex]\displaystyle y = 10,[/tex]which means we do NOT want a negative in front of the amplitude value, therefore we have this equation:
[tex]\displaystyle f(x) = 10cos\:\frac{\pi}{2}x + 10[/tex]
If you are having trouble figuring out which graph is which, just remember that the parent function of [tex]\displaystyle y = cos\:x[/tex]never touches the origin unless it shifts one unit south or gets reflected from somewhere. In this case, the photograph on the left touches the origin because of a reflection [negative symbol], therefore the photograph on the right matches the equation selected.
I am delighted to assist you at any time.
The correct function is,
⇒ y = 10 cos (π/2x) + 10
What is Function?A relation between a set of inputs having one output each is called a function.
Given that;
A cosine function has a period of 4.
Since, The period is 4.
Hence, The relationship between period and b (the coefficient of the independent variable of the cosine function) is, (period) =(2π/b).
Hence, We get;
⇒ 4b = 2π
⇒ b = 2π/4
⇒ b = π/2
So, Now our equation y = a cos (bx) + c becomes as;
⇒ y = 10 cos (π/2x) + 10
Thus, The horizontal center line of this cosine curve is y = 10. The maximum value of the curve is 20, which is 10 + 10, and the minimum value is 0, which is 10 - 10.

Step-by-step explanation:
Sum of angles in a quadrilateral = 360°
360° - 128° - 40° - 82° = 110°
Answer:
x = 110
Step-by-step explanation
The sum of the interior angles of a quadrilateral = 360°
Sum the given angles and equate to 360
82 + 40 + 128 + x = 360
250 + x = 360 ( subtract 250 from both sides )
x = 110
