Answer:100$
Step-by-step explanation: since the violin was 50 % off, that just means that the price it is is half of what it normally was , so you just multiple the fifty by 2 to get your answer which is that the violin cost 100$
Answer:
$100
Step-by-step explanation:
The price we are given already has the discount on it, so we know that
50% × original price = $50
50% fraction wise is [tex]\frac{1}{2}[/tex] or in decimal 0.5
So: 0.5 × original price = $50
original price = [tex]\frac{50}{0.5}[/tex] = $100

The sum of two numbers is –11. The difference of the two numbers is –7. What is the product of the two numbers?
Answer:
18
Step-by-step explanation:
According to the numbers the both numbers have to be negative
subtracting a negative will be the same as addition and so thats why the difference is bigger.
now its time for guess and check.
-6+-5
-11
but -6-(-5)=-1
so lets try
-9+(-2)=-11
-9-(-2)=-7
yay
so the product is
(-9)*(-2)=18
7x + 2y=-12
Y=-3x-4
Answer:
x=-4
Step-by-step explanation:
X would be -4 because if you distribute 2 to (-3x-4) it would give you (-6x-8) and then collecting like terms you would get (x-8=-12) then you would add 8 to -12 whih would equal -4.
A natural number is less than the sum of its opposite and 8. find all such numbers
Answer:
If 0 is included in the natural numbers: 0,1,2,3
If 0 is not included in the natural numbers: 1,2,3
Step-by-step explanation:
Let n denote the natural number.
Its opposite is -n
The sum of its opposite and 8 is
-n+8
This is greater than the natural number
n<-n+8
Solve for n
2n<8
n<4
The numbers are numbers that are less than 4
Let the natural number be nThe opposite of the number will be -nIf a natural number is less than the sum of its opposite and 8, this is expressed as:
n < -n + 8
n+ n < 8
2n < 8
n < 8/2
n < 4
Hence all the numbers are numbers that are less than 4

Answer:
YES

∆EFJ ≅ ∆HFG
Step-by-step explanation:
Side EF in ∆EFJ ≅ side HF in ∆HFG (corresponding sides)
Side FJ in ∆EFJ ≅ side FG in ∆HFG (corresponding sides)
Also,
<F in ∆EFJ ≅ <F in ∆HFG (vertical angles are congruent)
Thus, two sides and one included angle of ∆EFJ are congruent to two corresponding sides and an included angle of ∆HFG.
Therefore, by the SAS Congruence Theorem, ∆EFJ ≅ ∆HFG.

1. m<C = 48°.
2. <X = <Y.
Explanation :<ABD = <CDB = 62°
<BDA = <DBC = 70°
<DBC + <BCD + <CDB = 180°
70° + <BCD + 62° = 180°
132° + <BCD = 180°
<BCD = 180° - 132°
<BCD = 48°
m<C = 48°

Answer:
8 up, 6 left
Step-by-step explanation:
Locate any point from triangle A and go up 8 steps to get on the same level as triangle A'. Then, move to the left 6 steps.
The graph translated 6 unit left and 8 unit upward.
What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
Given, A figure "A" that translated at different position in cartesian plane.
Since, A translation is when a geometric figure slides up, down, left or right on the coordinate plane. The figure moves its location, but doesn't change its orientation. It also doesn't change its size or shape.
Thus, we can observe only one point on the figure and calculate the movement of the figure.
Lets focus on the left bottom corner of the figure.
It moves from the coordinates (1, -5) to the coordinates ( -5, 3)
Since Horizontally translating a graph is equivalent to shifting the base graph left or right in the direction of the x-axis
So, we can say it translated to the lefty by 6 unit.
Same it goes with vertical translation.
Therefore, The graph translated 6 unit left and 8 unit upward.

Find the vertex of the function given below.
y= 2x2 + 4x + 1
Answer:
vertex is (-1,-1)
Step-by-step explanation:
2 ways
1. get into vertex form y=a(x-h)^2+k
2. use math hacks
1.
vertex is (h,k) in y=a(x-h)^2+k
complete square
y=(2x^2+4x)+1
y=2(x^2+2x)+1
y=2(x^2+2x+1-1)+1
y=2((x+1)^2-1)+1
y=2(x+1)^2-2+1
y=2(x+1)^2-1
y=2(x-(-1))^2+(-1)
vertex is (-1,-1)
2.hack way
in form y=ax^2+bx+c
x value of vvertex is -b/2a
given
y=2x^2+4x+1
b=4, a=2
xvaluevertex=-4/(2*2)
xvaluevertex=-4/4=-1
sub back to find y value
y=2(-1)^2+4(-1)+1
y=2(1)-4+1
y=2-4+1
y=-1
y value is -1
Answer:
(-1,-1)
Step-by-step explanation:
To find the x coordinate, we use the formular x = -b/2a where b=4 and a = 2 from the given function.
hence x = -(4)/2(2) = -1
then to get the y coordinate we substitute the value of x into the given function, so y = 2(-1)^2+4(-1)+1 = -1
therefore, the vertex is (-1,-1)
