is y = 1 3 x a proportional relationship

Answer:

The 1st and the 3rd one

Step-by-step explanation:

2.3+(-2.3) ➡ 2.3 -2.3 = 0 ,so this option is correct

-3.7+(-4.1) ➡ -3.7 - 4.1 = -7.8 so this option isn't correct

-2.6-(-12/4) ➡-2.6 + 3 = 0.4 this option is also correct

(5/2)+(-2.5) ➡ 5/2 -5/2 = 0 this  would be undefined because we can't divide 0 by 2 or any other rational numbers

E.72-(-100) ➡72+100= 172  this option is incorrect because 172 is positive

5x + 6

Step-by-step explanation:

last one is the answer:D. X=12 and X=1

step by step:

d=b2-4ac=169-48=121

x1=(-b+√d)2a=(13+11)2=12

x2=(-b-√d)2a=(13-11)/2=1

X1=12 and X2=1

Answer:

I believe the measure of the sum of interior angles of  square is 360 degrees, and we know that all the angles are equal to 3x. You'd set up the equation to look like 3x+3x+3x+3x=360

simplify that, and you get 12x=360

this means x= 30

Answer:

5

Step-by-step explanation:

√((5-2)^2 + (-3-1)^2) = √(9+16) = 5

Answer:

5 units

Step-by-step explanation:

To Find :-

Solution :-

Using Distance Formula ,

> d = √[ ( 1 +3)²+ ( 2-5)² ]

> d = √[ 4² + 3² ]

> d = √ [ 16 + 9 ]

> d = √25

> d = 5

Answer:

The girls played 20 games.

Step-by-step explanation:

To fins how many games played. Divide the percentage lost by the number of games lost. Then divide the quotient from 100% to find how many games were played.

15% ÷ 3 = 5

100% ÷ 5 = 20 games

Answer:

-5 4/5

Step by Step:

-15.6 - 3.2 = -5.8

-5.8 > -5 4/5

Answer:

C

Step-by-step explanation:

The line goes right 2 up 3 so the slope must be 3/2. You can track the point (-3,-2) on the line in the graph.

=========================================================

Explanation:

Point Q is located at (0,w). We see that x = 0 and y = w.

So we'll replace x with 0 and y with w. Then we solve for w.

2x+3y = -12

2(0)+3(w) = -12

0+3w = -12

3w = -12

3w/3 = -12/3

w = -4

In the second to last step, I divided both sides by 3 to undo the multiplication of 3. Saying 3w means "3 times w".

Side note: The point Q is the y intercept as this is the location where the diagonal line 2x+3y=-12 crosses the vertical y axis.

Answer:

Step-by-step explanation:

Simplifying

5(4x + p) = w

Reorder the terms:

5(p + 4x) = w

(p * 5 + 4x * 5) = w

(5p + 20x) = w

Solving

5p + 20x = w

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Add '-20x' to each side of the equation.

5p + 20x + -20x = w + -20x

Combine like terms: 20x + -20x = 0

5p + 0 = w + -20x

5p = w + -20x

Divide each side by '5'.

p = 0.2w + -4x

Simplifying

p = 0.2w + -4x

Answer:

d = 101

Step-by-step explanation:

t = 11

11 x 11 = 121

-20 + 121 = 101

check: 101- 121 = -20 (correct)

Answer:

See Below.

Step-by-step explanation:

In the given figure, AP = BP = PC.

And we want to prove that ∠ABC is a right angle.

Since AP = BP and BP = PC, we can create two isosceles triangles: ΔAPB and ΔCPB.

By the definition of isosceles triangles, in ΔAPB, ∠PAB and ∠PBA are equivalent. Let the measure of each of them be x°.

Likewise, in ΔCPB, ∠PCB and ∠PBC are equivalent.

And since AP = BP = PC, each of the angles∠PCB and ∠PBC will also be equivalent to x°.

And since the sum of the interior angles of a triangle total 180°, we acquire:

[tex]\angle PAB+\angle PBA+\angle PCB+\angle PBC=180[/tex]

Since they are all equivalent:

[tex]4x=180[/tex]

Hence:

[tex]x=45^\circ[/tex]

∠ABC is the sum of ∠PBA and ∠PBC, each of which measures 45°. Hence:

[tex]\angle ABC=\angle PBA+\angle PBC=45+45=90^\circ[/tex]

Answer:

A

Step-by-step explanation:

A is equal to 5d-5

I just went through all eh choices

It can’t be b or c becuase when distributed, it automatically is -5d+25 or vice versa with a different sign so their out

D is impossible becuase you can’t jsut flip a subtraction problem

And A is possible because adding a negative basically means subtracting so if flipped The signs have to change

Answer:

it will be b
