∆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.

(Part A) I know the mean of x will be 1.35

Step-by-step explanation:

Just do 9 percent of 15, I nessecarly dont know how to do that math but I looked it up and gave me 1.35. and you got the mean. here is the homework my teacher gave me : I hope this helps

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

Answer:

x = 79 y = 22

Step-by-step explanation:

x would be the same as the other side so 79 * 2 would be 158. A whole triangle is 180. 180 - 158 = 22

Answer: y= 6x-4

Step-by-step explanation:

I wrote it in y=mx+b format. m is the slope and b is the y-intercept.

The slope is 6 because 12/2=6

Answer:

x < 7

Step-by-step explanation:

3x - 9 < 12     add 9 for both sides.

3x < 21      divide both sides by 3.

x < 7.

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)

Answer:

either 56.52 or 113.04

Step-by-step explanation:

if 18 is the diameter: C= 56.52 feet

if 18 is the radius: C= 113.04

Answer:

A

Step-by-step explanation:

[tex]\frac{5}{6}\cdot \frac{1}{2}=\frac{5}{12}[/tex]

Multiply top and bottom, on the top we get 5*1 which is 5 and on the bottom we get 6*2 which is 12.

Answer:

The answer for this would be B.

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.

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.

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.

1. m<C = 48°.

2. <X = <Y.

<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°

The triangle is a right triangle. If ZX = ZY then <X = <Y

Step-by-step explanation:

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

If 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
