which table represents y as a function of x

Step-by-step explanation:

P.S - The exact question is -

Given - Priya is simplifying the expression -2(4 - 2x) - 3 - 2x  Her work is shown to the left.  

To find - Priya's work is incorrect.  Explain the error she made.

Proof -

Priya simplified the problem as follows :

-2( 4 - 2x ) - 3 - 2x

-8 - 2x - 3 - 2x

-11 - 4x

But the simplification has to be like

-2( 4 - 2x ) - 3 - 2x

⇒-2(4) - 2(-2x) - 3 - 2x

⇒-8 + 4x - 3 - 2x

⇒-8 - 3 + 4x - 2x

⇒-11 + 2x

So, Priya made an error in the second line.

In the second line it has to be -8 + 4x - 3 - 2x but Priya has written -8 - 2x - 3 - 2x.

Answer:

Explanation:

single cone = $3

double cone = $5

total single = A = 3s

total double = B = 5d

As + Bd = 57

Cs + Ed = 15

A = 3 , B = 5

3s + 5d = 57

s + d = 15    (we don't know C and E yet)

multiply the second equation by 3 and substract it from the first equation

3s + 5d - 3s - 3d = 57 - 45

2d = 12

d = 6

Ed = 6

Cs = 15 - 6 = 9

A = 3 ($3)

B = 5 ($5)

C = 9 (single cones)

E = 6 (double cones)

Check:

(9 single cones × $3) + (6 double cones × $5) = 27 + 30 = 57

9 single cones + 6 double cones = 15

the sum of A, B, C and E:

A+B+C+E = 3+5+9+6 = 23

Answer:

Each packet cost $1.20

Step-by-step explanation:

$5 - $1.40 = $3.60

Divide $3.60 by 3 and you get $1.20.

Answer:

The only true statement is C

Step-by-step explanation:

The area of Amy's garden is 176 in²

The area of Burts garden is 324 in²

Therefore the only true statement is C.

Answer:

x = 45

Step-by-step explanation:

All triangles add up to 180°

x + 75 + 60 = 180

x + 135 = 180

x = 180 - 135

x = 45

im not sure i think its 14.2

Answer:

x=16/t

t=4 so

16/4 = 4

4 is your answer.

Answer:

y = 4

Step-by-step explanation:

To find the slope, you plug the coordinates into the slope formula.

y2 - y1/ x2 - x1

= 4 - 4/ -5 - 7

= 0

The slope is 0.

To find the y-intercept, y = 0x + b

4 = 0(7) + b

4 = 0 + b

4 = b

The equation is y = 4

Answer:

82 degrees

let the point where the lines cross be E

ABD angle is 108 / 2 = 54 degrees

CAB angle is 56 / 2 = 28 degrees

the missing angle in ABE triangle is 180-54-28=98 degrees. angle x is 180 - 98 = 82

Answer:

x-intercept and y-intercept are both 0

the domain (x) is [-4, 4]

the range (y) is [-4, 4]

Answer

x=3 or (3,0) and if you need it y=-2x+3

Step-by-step explanation:

Answer:

30

Step-by-step explanation:

Solve for the hypotenuse for the bottom triangle (a^2+ b^2=c^2). You should get 40. After solving that you should be able to solve for c in the top triangle which should get you 30.

Answer:

A= 347.65 B= 43.5

Step-by-step explanation:

A : 347.65

B : 43.5

244.5

+ 1 0 1. 1 5

= 347.65

68.2

- 24.7

= 43.5

Respuesta:

1/6

Explicación paso a paso:

La probabilidad es la probabilidad o probabilidad de que ocurra un evento. Se expresa como;

Probabilidad = Resultado esperado / Resultado total

Dado que la puntuación total de la muestra es 6 (13, 14, 17, 35, 39, 54)

Resultado total = 6

Dado que vamos a encontrar la probabilidad de ganar,

Puntuación ganadora = 54 (solo un resultado)

Resultado esperado = 1

Sustituir

Probabilidad de ganar = 1/6

Answer:

Step-by-step explanation:

so a rhombus is two triangles put together,  the area of a triangle is  1/2 b*h   and since we've got two  it's  2 ( 1/2 b * h )   so then it'  just  b * h

will be the area of the rhombus.    

the base is WY = 24 the height is  1/2 XZ = 30  so  15

24*15 = 360

Answer:

76%= Decimal: 0.76 and proportion 76%

Step-by-step explanation:

Answer:

Decimal=0.76 proportion=76%

Step-by-step explanation:

19/25 let's find the decimal first

long division:

25|19

25 goes into 1, 0 times so;

    0

25|19

   -0

     19

25 goes into 19 0 times so;

    00.

25|19.0

   -0

     19

     -0

     190

25 goes into 190 7 times so;

    00.7

25|19.00

   -0

     19

     -0

     190

    -175

       150

25 goes into 150  6 times so;

    00.76

25|19.00

   -0

     19

     -0

     190

    -175

       150

      -150

           0

now 19/25 as a proportion;

19........x

---- = ------

25.....100

25*4=100 so 19*4=x

19*4=76 so x = 76

and 76/100=76%
