Explain why an inverse variation function is not the best model for the data set?

ser-zykov [4K]

Answer:

Step-by-step explanation:

- The products of corresponding x- and y- values of an inverse variation function are constant.

- As x increases, y also increases.

-The product of the coordinate pairs are not equal: (165)(198)=32,670 and (170)(204)=34,680

77 prime or composite

Ludmilka [50]

<u><em>Seventy-seven is a composite number. </em></u>

Because you had to divide by eleven or seven. Then you can multiply by seven or eleven its equal to seventy-seven.

$77/11=7$

$11*7=77$

$77/7=11$

$7*11=77$

Final answer: $\boxed{=77}$

Hope this helps!

Which statement is true about the equations-3x 4y 12 and tx 1?

nydimaria [60]

We need to solve -3x+4y=12 for x

Let's start by adding -4y to both sides

-3x+4y-4y=12-4y

-3x=-4y+12

x = (-4y+12)/-3

x= 4/3 y -4

Now substitute 4/3 y -4 for x in 1/4 x - 1/3 y =1

1/4 x -1/3 y =1

1/4 (4/3 y -4) -1/3 y =1

Use the distributive property

(1/4)(4/3 y) + (1/4)(-4) -1/3 y =1

1/3 y -1 - 1/3 y =1

Now combine like terms

(1/3y -1/3y) + (-1) =1

= -1

-1 = 1

Now add 1 to both sides

0=2

So there are no Solutions

The answer is C

I hope that's help Will :)

Answer:

Step-by-step explanation:

To be right triangle has to verify the Pythagorean Theorem

hypothenuse² = (side 1 )² + (side 2)²

Since the hypothenuse is the largest of the sides we consider the largest number the hypothenuse and check the relation.

16, 30, 34

34² = 16²+30²; 1156 = 1156 ✅

16, 30, 34 are measurements of a right triangle

8, 14, 16

16² = 8² +14²; 256 = 260 ❌

8, 14, 16 is not a right triangle

10, 12, 16

16² = 10² +12²; 256 = 244 ❌

10, 12, 16 is not a right triangle

5, 12, 13

13² = 12²+5²; 169 = 169 ✅

5, 12, 13 are measurements of a right triangle
