The slope of Consider the line whose equation is 3x + y - 3 = 0. The slope of any line that is parallel to this line is any line that is perpendicular to this line is
Answer:
parallel : y = -3x + 3
perpendicular : y = 1/3x + 3
Step-by-step explanation:
rewrite 3x + y - 3 = 0
y = -3x + 3
parallel has the same slope
so
parallel : y = -3x + 3
perpendicular is negative reciprocal of the slope
so
-3x becomes 1/3x
so
perpendicular : y = 1/3x + 3

Write the equation of the parabola in vertex form.
vertex (3,3), point (2, - 1)
Step-by-step explanation:
The vertex form of a parabola is given by
[tex]y = a(x - h)^2 + k[/tex]
where (h, k) are the coordinates of the vertex of the parabola. So we can write our parabola as
[tex]y = a(x - 3)^2 + 3[/tex]
We know that our curve goes through the point (2, -1) so we can solve for the constant a as follows:
[tex]-1 = a(2 - 3)^2 + 3 \Rightarrow -1 = a + 3[/tex]
or
[tex]a = -4[/tex]
Therefore, the vertex form of the equation for the parabola is
[tex]y = -4(x - 3)^2 + 3[/tex]

A scale drawing of an office space uses a scale of 1 in : 4 yd. The scale drawing has an area of 12 square inches.The area of the office space is ____ square yards
The scale factor of area of the drawing to the area of the office is the
square of the scale factor of the length of the drawing.
The area of the office space is 192 square yards.Reasons:
The given parameters are;
1 inch in the scale drawing = 4 yd. in actual dimension
4 yd. = 144 inches
Therefore;
1 inch in the scale drawing = 144 inches in actual dimension
The scale factor of length of the drawing, s = 1:144
The scale factor of area = s²
Therefore, we have;
[tex]\dfrac{Drawing \ area}{Actual \ area} =s^2[/tex]Therefore, we have;
[tex]\dfrac{Drawing \ area}{Actual \ area} =\dfrac{12}{A} = s^2 = \left( \dfrac{1}{144} \right)^2[/tex]Where;
A = The actual office space area
There fore;
12 × 144² = A × 1²
A = 12 × 144² = 248,832 in.²
1 yd.² = 1,296 in.²
[tex]248,832 \, in.^2 = \dfrac{248,832}{1,296} \, yd.^2 = 192 \, yd.^2[/tex]The area of the office space is 192 square yards.

The table shows the cost of taking a rideshare trip. Which description correctly reflects the way the charges are calculated?
A)
The ride requires a $14 initial fee, plus 50 cents per mile driven
B
The ride requires a $14 initial fee, plus 51.90 per mile driven
The ride requires a $14 Initial fee, plus 52.15 per mile driven
D
The ride requires a 514 initial fee, plus 52.50 per mile driven
The table is an illustration of a linear function.
The description of the charges is: A) The ride requires a $14 initial fee, plus 50 cents per mile driven
The base fee is the charges, when the number of miles is 0
From the table;
y = $14, when x = 0
So, the base fee is $14
Next, we calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
From the table, we have:
[tex]m = \frac{16.5 - 14}{5-0}[/tex]
[tex]m = \frac{2.5}{5}[/tex]
[tex]m = 0.5[/tex]
The above means that:
The cost per mile is $0.5 (i.e. 50 cents)
Hence, the description of the charges is: A) The ride requires a $14 initial fee, plus 50 cents per mile driven

Find the surface area and volume of the basketball. Round your answer to the nearest hundredth.
Answer:
Surface area: 277.59 in^2
Volume: 434.89 in^3
Step-by-step explanation:
Radius = C/(2*pi)
29.5/3.14 = 9.39
Radius = 9.39/2 = 4.7 in
A = 4 pi r^2
A = (4) (3.14) (4.7)^2
A = 277.59 in^2
Volume = (4/3) (pi)(r)^3
(4/3)(3.14)(4.7)^3
= 434.89 in^3
Answer:
Surface area: [tex]277.59[/tex] in^[tex]2[/tex]
Volume: [tex]434.89[/tex] in^[tex]3[/tex]
Explanation:
Radius = C/([tex]2[/tex]*[tex]Pi[/tex])
[tex]29.5/3.14[/tex] = [tex]9.39[/tex]
Radius = [tex]9.39/2[/tex] = [tex]4.7[/tex] in

What is the inequality shown?
The Inequality shown here is :
[tex] - 3 \leqslant x < 2[/tex]In the standard (x,y) coordinate plane, point A has coordinates (–9,–1). Point A is translated 9 units to the right and 1 unit up, and that point is labeled A′. What are the coordinates of A′ ?
A.(-18,-2)
B.(-10,-10)
C.(-9,-2)
D.(0,0)
E.18,2)
Translation involves changing the position of a point in the coordinate plane.
The coordinate of the translated point A' is (D) (0,0)
The coordinate of the point is given as:
[tex]A = (-9,-1)[/tex]
The rule of translation 9 units right, and 1 unit up is:
[tex](x,y) \to (x+9,y+1)[/tex]
So, we have:
[tex]A' = (-9+9,-1+1)[/tex]
Simplify the expression
[tex]A' = (0,0)[/tex]
Hence, the coordinate of the translated point A' is (D) (0,0)

https://brainly.com/question/18549175
If the coordinate is translated 9 units right and 1 units up, the resulting coordinate will be at (-9 + 9, -1 + 1) which is A'(0, 0). Option D is correct
Given the coordinate point A (x, y), if the coordinate is translated a unit right and b units up, the resulting coordinate will be at (x + a, y + b)
Note that both values are added to the coordinate points.
Given the coordinate point A (-9, -1), if the coordinate is translated 9 units right and 1 units up, the resulting coordinate will be at (-9 + 9, -1 + 1) which is A'(0, 0)

i need step by step explaniton. judy has $3,024 dollars in her bank account she is planning to spend this money on buying tickets to disney world for her and 11 of her friends. two of judy's friends decided to help but the tickets and offered her $1,00 each. how munch did each ticket cost. (round the answer to the nearest whole number) this is a long divison problem.
Answer:
uhh judy has $3.024 in her bank acc
She is buying tickets for 11 friends and including herself too that means 12
Two friends decided help to buy the tickets and offered $100 each i.e $200
So I'm guessing that the cost price of one ticket is $100
Now than since 2 people paid their ticket cost than that means only 10 people left
Than for buying tickets for 10 people would cost (10×100=1000)
So I guess buying the tickets cost 1000 or if we add other two people's cost than that makes 1200
