Mrs. Clarke saved $60 by buying a dress at a 30% discount. The original price of the dress was
Answer:
$200Step-by-step explanation:
Step one:
given
let the original price of the be x
discount = 30%
30 of x is $60
Step two:
Mathematically
30/100*x=60
0.3x=60
divide both sides by 0.3
x=60/0.3
x=200
Hence the original price of the dress is $200

The transformation formula of a horizontal-facing parabola is:
x = ±a(b(y - k)) + h, where the vertex is at (h, k).
Looking at the graph, we can see a vertex at (-2, -3) with a stretch of 2. The graph is also pointed towards the RIGHT, which means that the coefficient "a" must be positive. Therefore:
The only logical answer choice is B, or x = 2(y + 3)² - 2.
The formula indicates that:
* Vertex at (-2, -3)
* Stretch of 2
* Right-facing parabola

Step-by-step explanation:
See attached Screenshot using Desmos to write equation.
solve the inequality
7y+2<5y+12
Answer:
y < 5
Step by step:Step 1: Subtract 5y from both sides.
7y+2−5y<5y+12−5y
2y+2<12
Step 2: Subtract 2 from both sides.
2y+2−2<12−2
2y<10
Step 3: Divide both sides by 2.
[tex]\frac{2y}{2}[/tex] < [tex]\frac{10}{2}[/tex]
= y < 5

Answer:h
Step-by-step explanation:
Please help! Only if you KNOw, I’m confused
Answer:
40
Step-by-step explanation:
1.Kknow the following information;
Remember, the sum of degrees of angles in a triangle is 180.
So say if a traingle contained;
<1, <2, <3,
Then:
<1 + <2 + <3 = 180
2. State the given, and set up an equation;
In this case, it is given that;
<1 = 115
<2 = 25
Therefore, set up the equation;
115 + 25 + <3 = 180
3. Solve the equation;
115 + 25 + <3 = 180
Simplify,
140 + <3 = 180
Inverse operations,
140 + <3 = 180
-140 -140
<3 = 40

Answer:
(tan(theta)-1)^3
= (tan(theta)-1)(tan(theta)-1)(tan(theta)-1)
= (tan^2(theta)-2tan(theta)+1)(tan(theta)-1)
= tan^3(theta)-2tan^2(theta)+tan(theta)-tan^2(theta)+2tan(theta)-1
= tan^3(theta)-3tan^2(theta)+3tan(theta)-1

what is the slope and y-intercept of this graph?
Answer:
Slope is 2
Y-intercept is 7
Step-by-step explanation:
To find the slope we take any two points from the table
and use it in the formula :
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\[/tex]
we take the points (0,7) and (1,9)
now we put these points in the formula and it becomes
[tex]m=\frac{9-7}{1-0}[/tex]
[tex]m=2[/tex]
so our slope which is m is 2 and now for the y-intercept we use the standard equation
[tex]y=mx+c[/tex]
where c is the y-intercept
we use the value of m which is 2 and use any point from the table lets take (0,7)
[tex]y=mx+c\\7=(2)(0)+c\\7=c[/tex]
our y-intercept which is c is 7
so finally our slope is 2 and y-intercept is 7

Answer:
Number & Cost($)
Feet & Yards
Step-by-step explanation:
Number & Cost:
(2, 38), (4, 76) <====== pick any two point to find constant
constant = (y₂ - y₁) / (x₂ - x₁)
= (76 - 38) / (4 - 2)
= 38 / 2
= 19 <====== k the constant
y = kx
y = 19x
point (2, 38): 38 = 19(2) ===> 38 = 38
point (4, 76): 76 = 19(4) ===> 76 = 76
point (7, 133): 133 = 19(7) ===> 133 = 133
point (9, 171): 171 = 19(9) ===> 171 = 171
Feet & Yards:
(27, 9), (75, 25) <====== pick any two point to find constant
constant = (y₂ - y₁) / (x₂ - x₁)
= (25 - 9) / (75 - 27)
= 16 / 48
= 1/3 <====== k the constant
y = kx
y = 1/3x
point (3, 1): 1 = 1/3(3) ===> 1 = 1
point (12, 4): 4 = 1/3(12) ===> 4 = 4
point (27, 9): 9 = 1/3(27) ===> 9 = 9
point (75, 25): 25 = 1/3(75) ===> 25 = 25
