Answer:

D.

Step-by-step explanation:

To see if a line is parallel to y = -(2/3)x + 8 you need to check if the coefficients at y and x are of the same ratio. This immediately removes answers A and C, because of the wrong sign at x compared to y.

What's left is to see which of the answers B and D passes through (4, -5) by inputting x = 4 and y = -5

B.

left = -5 - 5 = -10

right = -(2/3)(4 + 4) = -16/3

So it's D. Let's verify:

D.

left = -5 + 5 = 0

right = -(2/3)(4 - 4) = 0

Checks out.

Answer:

Option D

Step-by-step explanation:

→ Find the gradient of the parallel line

[tex]y=-\frac{2}{3} x+c[/tex]

→ Substitute in the coordinates as x and y values to find c

[tex]5=-\frac{2}{3} *-4+c[/tex]

→ Simplify

[tex]5=\frac{8}{3} +c[/tex]

→ Minus  [tex]\frac{8}{3}[/tex]  from both sides to find c

[tex]c = \frac{7}{3}[/tex]

→ Expand out all options and then see which one contains all the numbers above

Option D

Answer: The unit rate is 16 miles per gallon

Step-by-step explanation:

464 miles for 29 gallons

? miles for 1 gallon

29x = 464

Divide both sides by 29

x = 16

Answer:

x - 13 = 13 - x

Step-by-step explanation:

The commutative property of addition is a+b=b+a

The third equation is the only one not following the rule. It states that a-b=b-a, whoich is not true.

For exaple, 2-1 is not equal to 1-2.

Answer: 2 1/2kg

Step-by-step explanation:

Weight of plant food bought = 4 1/2kg

Amount used on strawberry plant = 1 2/3kg

Amount used on tomato plant = 1/4kg

Therefore, the amount used will be:

= 1 2/3 + 1/4

= 1 8/12 + 3/12

= 1 11/12kg

We then subtract the value gotten from the amount bought. This will be:

= 4 1/2 - 1 11/12

= 4 6/12 - 1 11/12

= 2 6/12

= 2 1/2kg

Answer:

I think the answer is only 6 items that was used in making the container with the help of the net.

but for the calculation, you have to add the the given dimensions to get the answer

Answer:

Step-by-step explanation:Vertex form of a quadratic equation is y=a(x-h)2+k, where (h,k) is the vertex of the parabola.

The vertex of a parabola is the point at the top or bottom of the parabola.

'h' is -6, the first coordinate in the vertex.

'k' is -4, the second coordinate in the vertex.

'x' is -2, the first coordinate in the other point.

Answer:

  y = -3/2x +11

Step-by-step explanation:

The slope of the parallel line is the same as the slope of the given line, so ...

  m = -3/2

The y-intercept of the parallel line can be found from ...

  b = y -mx

  b = 5 -(-3/2)(4) = 11

So, the desired equation is ...

  y = mx +b

  y = -3/2x + 11

_____

Additional comment

Since you know the slope and a point on the desired line, you can write down the equation directly using the point-slope form. No additional math is required.

  y -5 = -3/2(x -4)

Answer:

22

Step-by-step explanation:

11% of 196 = 21.56

Divide by 10 and divide by 100. Add them together

You must round this up because you cant really have .56 of a person.

Answer:

x = 3z(y - 2)

Step-by-step explanation:

Given

[tex]\frac{x}{3z}[/tex] = y - 2 ( multiply both sides by 3z to clear the fraction )

x = 3z(y - 2)

Actually Welcome to the Concept of the Simple maths.

Here,

61 = r/3 - 7

hence, r/3 = 61+7

===> r/3 = 68

==> r = 68*3

====> r = 204

Option c.) is correct.

Answer: 5x4x8x4x5x2x6x8x1

Step-by-step explanation:

Answer:

32 Square centimeters

Step-by-step explanation:

You have to seperate the shape into triangles and rectangles. if you do this, you get 2 identical triangles and 2 different rectangles. one of the rectangles is 8 square cm, the other is 12. you can see that the base of each of the 2 triangles is 3 cm long. 2 halves=1 whole, so the 2 triangles turn into 1 rectangle. therefore, you have to add 12+12+8. That is 32 square centimeters.

Hope my answer helped!

Answer: D

Step-by-step explanation:

Answer:

5x^2-4+4(x^2)-6x

Step-by-step explanation:

first you need to remove the unnecessary parentheses it should look like this: 5x^2-7-(4(x^2)+6x-3)

then you should calculate the sum it should look like this: 5x^2-4+4(x^2)-6x and that is your answer

Step-by-step explanation:

Answer: there were 12 chocolates in each box. (Originally, before any got eaten)

Step-by-step explanation: let x represent the total amount of chocolates in each box.

8x - 3(8) = 72

8x - 24 = 72 add 24 to both sides

8x = 96 divide both sides by 8

X = 12

Answer:

That means you had 48 chocolates in each box

Step-by-step explanation:

Since you eat 3 chocolates from all 8 boxes, you do this:

8 x 3 which = 24

Now since you have 72 chocolates left you do this:

72 - 24 which = 48

So, therefore, there were originally 48 chocolates in each box

(Don't eat so much chocolate lol you could get sick)

Answer:

A = 16π cm²

Step-by-step explanation:

We require to find the radius r

Given circumference C = 8π , then

2πr = 8π ( divide both sides by 2π )

r = 4 , then

A = πr² = π × 4² = 16π cm²

Answer:

A = 16π cm²
