Answer:

1/2p - 1/4p - 4.

Step-by-step explanation:

1/2p - (1/4p + 4)

= 12p - 1/4p - 4

≠ 1/2p + 1/2p - 4

Instead of writing -1/4p, Tim wrote 1/2p

Answer:

centre = (-5, -4)

radius = 7.42

Step-by-step explanation:

The general form for center-radius is

(x - h)² + (y - k)²= r²

Center = (h, k)

Radius = r

Rearrange the equation.

(x² + 10x) + (y² + 8y) - 14 = 0

Add 14 on both sides.

(x² + 10x) + (y² + 8y) = 14

(10/2)² = 25

(8/2)² = 16

Add 25 and 16 to both sides.

(x² + 10x + 25) + (y² + 8y + 16) = 14 + 25 + 16

Factor left side of the equation.

(x+5)² + (x+4)² = 55

(55) = (7.416198)²

(x+5)² + (x+4)² = 7.42²

The radius is 7.42.

The centre is at (-5, -4).

Answer:

x=15/8; x ≈ 1.88

Step-by-step explanation:

cross products

15=8x

Divide both sides by 8

x = 1.875 = 15/8

x ≈ 1.88

1. In the first problem, we need to subtract 1 from 9 since there is an addition:

9 – 1 = 8

Next, divide 8 by 2, and we get:

8 ÷ 2 = 4

This means that x = 4

Finally, check the answer by:

2(4) + 1 = 9

2. In the second problem, we need to subtract 3 from 19 since there is an addition:

19 – 3 = 16

Next, divide 16 by 4, and we get:

16 ÷ 4 = 4

This means that x = 4

Finally, check the answer by:

4(4) + 3 = 19

3. In the third problem, we need to add 2 with 7 since there is subtraction:

2 + 7 = 9

Next, divide 9 by 3, and we get:

9 ÷ 3 = 3

This means that x = 3

Finally, check the answer by:

3(3) – 2 = 7

Hope this helps :)

Answer:

A is 23x+2=94

B is 4

C is 20.5 by 26.5

Step-by-step explanation:

To solve get the equation, you have to combine the two equations, which gets you 5.5x -1.5 + 6x +2.5

Then you combine like-terms, which is 5.5x+6x and -1.5 +2.5 and that equals 11.5x + 1 and then multiply that by 2 {2(11.5x +1) } and you should get

23x+2 and then put the 94 at the end (23x + 2 = 94). Then just solve the equation and you get the rest of the answers.

Answer:

The scaling factor is 4.

Step-by-step explanation:

To find the scaling factor from A to B, we must know that these are similar triangles.  Since this is not stated in the problem, we will assume these are similar triangles.

Similar triangles simply have the same scaling ratio, allowing for any size triangle to be created with the same relative dimensions.  With this in mind, let's check to see the multiple of each side by simply taking the sides of the triangle B divided by the sides of triangle A.

40 / 10 = 4

44 / 11 = 4

72 / 18 = 4

Notice how each of the sides from triangle B to triangle A has the same multiple, 4.  This tells us that the scale from A to B is 4.

Hence, the scaling factor is 4.

Cheers.

Answer:

Answer:

y=kx

2=k.-4

k=-1/2

then

y=-1/2×20

y=-10

Answer:

y = - 10

Step-by-step explanation:

Given that y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 2 when x = - 4, that is

2 = - 4k ( divide both sides by - 4 )

\(\frac{2}{-4}\) = k, that is

k = - \(\frac{1}{2}\)

y = - \(\frac{1}{2}\) x ← equation of variation

When x = 20, then

y = - \(\frac{1}{2}\) × 20 = - 10

m=2/5

a)  the slope is 2/5 = .4 which is below the boundary guideline.  So no this is not with in carpenter's guidelines

b) the image below show a line with slope 2/5 but with intercept 3

c) the stairs can be draw on the line with rise 2 run 5   from the line.  see image

d)equation is in image

Answer:

y = 15

Step-by-step explanation:

We need to solve for k

y = x

21 = 7k  Divide both sides by 7 to solve for k

3 = k

y = xk

y = 5(3)

y = 15

Answer:

\(A=\frac{ab}{2}\) or \(A = a *\sqrt{c^2-a^2} /2\)

Step-by-step explanation:

Depending on the values you take depends on the equation you would use to solve for the area of a right triangle(the first answer accounts for measuring both arms(the sides connected to the 90 degree angle(a and b)), where as the second answer accounts for using the hypotenuse and one of the arms). That means that a 90 degree angle is involved, or as illustrated here, the square in the bottom right corner. If this were a non-right angle triangle, a different formula utilizing the height of the triangle would be used instead.

\(A = \frac{h_{b}+b}{2}\)

Since the right angle exists, a height is already given using one of the arms of the triangle in its place. We can also confirm it is a triangle by adding up all degrees of the triangle, in which it would equal 180 degrees confirming it is indeed a triangle as well.

By using trigonometric relations we will see that the area is:

How to find the area of one triangular section?

Remember that the area of a right triangle is equal to the product between the cathetus divided by 2.

Sadly, here we don't have the measures of any sides of the triangle, so getting the actual area is impossible, but if we assume that some dimension is given (like the height, let's say that is h).

h is the cathetus adjacent to the 60° angle, then the other cathetus (the bottom one) is given by:

tan(60°) = x/h

x = tan(60°)*h

Then our two catheti are h and tan(60°)*h.

This means that the area will be:

Here we only used trigonometric properties, so this area will work for any height given (always that the value of h is the cathetus adjacent to the 60° angle).

Answer: for the first ss, c > 32

we can say this is true because she needs to buy MORE THAN 8 pound of candy, for 4 dollars each, given that the question wants us to find the amount of MONEY she spends on the candy, you have to factor in that each pound of candy equals 4 dollars, 4 x 8 = 32, but it needs to be a greater than inequality because she wants to buy MORE THAN 8 pounds of candy.

for ss number 2. your answer is 58, and i honestly cannot explain how i got the answer, other than literally plugging in numbers

kind of an annoying answer, im sorry, but i really couldnt explain ss 2 if i tried

also looking back at ss 1 let me know if there is more to that question since i might have looked at it wrong, the answer holds true, but they might be looking for more than 1 way to find that answer
