Answer:

2.6 pounds of apples; 1.2 pounds of bananas

Step-by-step explanation:

$1.90 X 2.6 = $4.94

$.75 X 1.2 = $.9

$4.94 + $.9 = $5.84

7) Use distributive property
3x(4x⁴ - 5x)=3x*4x⁴- 3x*5x = 12x⁵ - 15x²
8) When you open parenthesis with minus sigh in front of it, you need change sings of the terms on opposite. Then find like terms.
(5x⁴-3x³+6x)-(3x³+11x²-8x)= 5x⁴-3x³+6x -3x³-11x²+8x =5x⁴-6x³ - 11x²+14x
9)(x-2)(3x-4)=x*3x-4x-6x+8=3x²-10x+8
10) (x+6)²=(x+6)(x+6)=x²+6x+6x+36=x²+12x+36
For (x+6)², you can also use the formula of the perfect square
(a+b)²=a²+2ab+b²
For (x+6)² =x²+2*x*6 +6²=x²+12x+36

Cuál es la altura del cono si tiene un diámetro de 18 cm y un volumen de 1.696.464 cm3 ?
bogdanovich [222]

Answer:

Altura = 20,000 cm

Step-by-step explanation:

V = (pi x r^2 x a)/3

1.696.464 = (3.14 x 9^2 x a) / 3

1.696.464 = 84,82 altura

1.696.464 / 84,82 = altura

a = 20,000cm

Line 1: 2x-3y>12
nata0808 [166]

Answer:

  • The graph of this line i.e. 2x-3y>12 should be BELOW the DOTTED line as y involves < symbol.
  • The graph of this line i.e. y>-2x+5  should be ABOVE the DOTTED line as it involves > symbol.
  • The correct graph for line 1  and line 2 is shown in attached figure.

Step-by-step explanation:

  • If the inequality involves < or >, then the graph of the equation involves a dotted line.  
  • If the inequality involves ≤ or ≥, then the graph of the equation involves a solid line.

<em>Considering the line 1</em>

2x-3y>12

Solving line 1

2x-3y>12

-3y>12-2x

3y

y

As y involves < symbol, so the graph of this line should be BELOW the DOTTED line.

But, as you can see that there is an error in the graph. As the graph of  y is being shown ABOVE the SOLID line.

Therefore, the graph of this line i.e. y should be BELOW the DOTTED line as it involves < symbol.

<em>Considering the line 2</em>

y>-2x+5

As y>-2x+5 involves > symbol, so the graph of this line should be ABOVE the DOTTED line.

But, as you can see that there is an error in the graph. As the graph of  y>-2x+5 is being shown ABOVE the SOLID line.

Therefore, the graph of this line i.e. y>-2x+5 should be ABOVE the DOTTED line as it involves > symbol.

The <em>correct graph</em> for line 1 i.e. 2x-3y>12 and line 2 i.e. y>-2x+5 is shown in <em>attached figure</em>.

From the attached graph, it is shown that only (5, -2) satisfies the both inequalities. So, (5, -2) is the correct solution for the given inequalities.

<em>Solution Verification:</em>

<u><em>Putting (5, -2) in line 1 and line 2</em></u>

For line 1:

2x - 3y > 12 ⇒ 2(5) - 3(-2) > 12 ⇒ 10 + 6 > 12 ⇒ 16 > 12 which is true.

For line 2:

y > -2x + 5 ⇒ -2 > -2(5) + 5 ⇒ -2 > -10 + 5 ⇒ -2 > -5 which is true.

So, (5, -2) is IN the solution for line 1 and line 2

<em><u>Putting (-1, -1) in line 1 and line 2</u></em>

For line 1:

2x - 3y > 12 ⇒ 2(-1) - 3(-1) > 12 ⇒ -2 + 3 > 12 ⇒ 1 > 12 which is false.

For line 2:

y > -2x + 5 ⇒ -1 > -2(-1) + 5 ⇒ -1 > 2 + 5 ⇒ -1 > 7 which is false.

So, (-1, -1) is NOT in the solution for line 1 and line 2

<em><u>Putting (0, 5) in line 1 and line 2</u></em>

For line 1:

2x - 3y > 12 ⇒ 2(0) - 3(5) > 12 ⇒ 0 - 15 > 12 ⇒ -15 > 12 which is false.

For line 2:

y > -2x + 5 ⇒ 5 > -2(0) + 5 ⇒ 5 > 0 + 5 ⇒ 5 > 5 which is false.

So, (0, 5) is NOT in the solution for line 1 and line 2
