true or false: y=x³-4 is a linear equation​

Answer:

x = 3

Step-by-step explanation:

Use distributive property: a(b +c) =(a*b) + (a*c)

3(x + 6) = 27

3*x + 3*6 = 27

3x + 18  = 27 {Subtract 18 from both sides}

3x + 18 -18 = 27 - 18

         3x    = 9  {Divide both sides by 3}

        3x/3 = 9/3

x = 3

Answer:

the equation doesn't have z as an exponent so i can't answer it

Step-by-step explanation:

Z = 5/8

-3 = 2 - 8z

-3= -8z +2

Answer:

36 cm

43.27 cm

Step-by-step explanation:

[tex]r_1[/tex] = Radius of bucket = 18 cm

[tex]h_1[/tex] = Height of bucket = 32 cm

[tex]r_2[/tex] = Radius of cone

[tex]h_2[/tex] = Height of cone = 24 cm

The volume of the cylindrical bucket and the conical heap of sand is equal so

[tex]\pi r_1^2h_1=\dfrac{1}{3}\pi r_2^2h_2\\\Rightarrow r_2=\sqrt{\dfrac{3r_1^2h_1}{h_2}}\\\Rightarrow r_2=\sqrt{\dfrac{3\times 18^2\times 32}{24}}\\\Rightarrow r_2=36\ \text{cm}[/tex]

The radius of the heap is 36 cm.

Slant height is given by

[tex]l=\sqrt{r_2^2+h_2^2}\\\Rightarrow l=\sqrt{36^2+24^2}\\\Rightarrow l=43.27\ \text{cm}[/tex]

The slant height of the heap is 43.27 cm.

Answer:

[tex]c \div \frac{1}{2}y = x \\[/tex]

y = 1

Step-by-step explanation:

600,000 ÷ 1/2 = 300,000

c = 600,000

y = 1/2

Step-by-step explanation:

the closest one is but the actual number is 8.6 repeating so 8.7 is correct

Answer:

2 1/6

Step-by-step explanation:

3 ÷ 2 = 1 1/2

Answer:

Option A

1

Step-by-step explanation:

7x + 7 = 18 - 4x. [Alternate interior angle]

=> 7x + 4x = 18 - 7

=> 11x = 11

[tex] = > x = \frac{11}{11} [/tex]

=> x = 1 (Ans)

Answer:

Los primeros 2 días que el camión visita ambas calles el mismo día es el 15 y 30 de diciembre.

Step-by-step explanation:

Los múltiplos de un número son todos los posibles resultados de multiplicar ese número por todos y cada uno de los números naturales.

Es decir, los múltiplos de un número natural son los números naturales que resultan de multiplicar ese número por otros números naturales.

El conjunto de los múltiplos de un número determinado (salvo el cero) es infinito, pues existen infinitos naturales para multiplicar.

Para determinar cuáles son los primeros 2 días que el camión visita ambas calles el mismo día, debes encontrar los múltiplos de 3 y 5:

múltiplos de 3: 3; 6; 9; 12; 15; 18; 21; 24; 27; 30

múltiplos de 5: 5; 10; 15; 20; 25; 30; 35; 40; 45; 50

Podes observar que los 2 primeros números comunes o que coinciden entre los múltiplos de 3 y 5 son 15 y 30. Esto quiere decir que los primeros 2 días que el camión visita ambas calles el mismo día es el 15 y 30 de diciembre.

Rewrite the fractions so they have a common denominator

3/4 = 15/20

Now add:

4 15/20 + 7 11/20 = 11 26/20

26/20 simplifies to 1 3/10

11 + 1 3/10 = 12 3/10 total minutes

ok thx for my points back

Step-by-step explanation:

The First equation and the Third Equation

are equivalent to 6x - 24.

1) 6 ( x - 4 )

3)3 ( 2x - 8 )

Answer:

first one and third one. hope u get it right!

Step-by-step explanation:

6(x-4)

distribute (6*x and 6*4) then it equals 6x - 24

2(3x - 24) = 6x - 48

3(2x - 8) = 6x - 24

3(3x - 21) = 9x - 63

Answer:

-30 feet

Step-by-step explanation:

If ground level is 0, and the dolphin goes 30 feet below 0, then the dolphin's elevation is -30 feet.

Answer:

Step-by-step explanation:

base length b = 32 cm

slant height L = 30 cm

height h = √(L²-(½b)²)

= √(30²-0.25·32²)

≅ 25.3771550809 cm

volume V = (⅓)b²h

= (⅓)32²·25.38

≅ 8662.07 cm³

x= 30.....................

Answer:

x=30

Step-by-step explanation:

how:

so your equation right now is 2x+40=100, so figure this equation out you have to do the opposite so it will be

100-40=60

60/2=30

which makes x=30

Answer:

.0024

Step-by-step explanation:

Hey There!

So when converting a percentage to a decimal all we have to do is move the decimal place over to the left 2 times

so it would be .0024

hope this helps ~ MarkAnswers

Answer:

0.0024

Step-by-step explanation:

0.24% = 0.0024 in decimal form. Percent means 'per 100'. So, 0.24% means 0.24 per 100 or simply 0.24/100.

i hope this helps!! brainliest?

Answer:

4x+36

Step-by-step explanation:

All you have to do is multiply the 4 by the numbers inside the parentheses.

4 times x is 4x

4 times 9 is 36

You can't find the answer since you don't know what x is.

I hope this helps, and have a great day! :)

Answer:

0.12 or 12%

Step-by-step explanation:

I=Prt

r= I/(Pt)

r = 160/(2000 x 8/12)

Answer:

Step-by-step explanation:

Area is the product of two dimensions.

If each dimension is doubled, then the area becomes 2*2 = 4 times greater.

If each face is 4 times greater, then their sum will be 4 times greater.

The sum of the faces is the total surface area, therefore the B's surface area is 4 times as great as A's surface area.

Answer:

x=28

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

x+5+x−5=56

x+5+x+−5=56

(x+x)+(5+−5)=56(Combine Like Terms)

2x=56

2x=56

Step 2: Divide both sides by 2.

2x/2=56/2

x=28
