What is the difference between 4/5- 1/2 *

Mathematics
2 answers:
Nitella [24]3 years ago
5 0

Answer:

3/10

Step-by-step explanation:

1. find the lowest common denominator which is 10.

2. for 4/5 you have to multiply 5 by 2 in order to get 10, so you multiply the numerator by 2 as well which gives you 8/10.

3. for 1/2 you have to multiply 2 by 5 in order to get 10, so you multiply the numerator by 5 also which gives you 5/10

4. you work out the difference between both numerators which is 3 and keep the denominator the same

Find the equation of the linear function x 1 2 3 4 y 6 9 12 15​
vredina [299]

Answer:

The equation of the linear function is y = 3x + 3

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

  • m is the slope
  • b is the y-intercept

The rule of the slope is m = \frac{y2-y1}{x2-x1} , where

  • (x1, y1) and (x2, y2) are two points on the line

∵ A line passes through points (1, 6) and (2, 9)

∴ x1 = 1 ad y1 = 6

∴ x2 = 2 and y2 = 9

→ Use the rule of the slope above to find the slope of the line

∵ m = \frac{9-6}{2-1} = \frac{3}{1} = 3

∴ m = 3

→ Substitute the value of m in the form of the equation above

∴ y = 3x + b

→ To find b substitute x and y in the equation by the coordinates of any

   point on the line

∵ x = 1 and y = 6

∴ 6 = 3 (1) + b

∴ 6 = 3 + b

→ Subtract 3 from both sides

∵ 6 - 3 = 3 - 3 + b

∴ 3 = b

→ Substitute the value of b in the equation above

∴ y = 3x + 3

∴ The equation of the linear function is y = 3x + 3

serious [3.7K]

Answer:

He will use the D box because it has a volume of

27 {ft}^{3}

Step-by-step explanation:

a)v = whl \\  = 1 \times 5 \times 3 \\  = 15 {ft}^{3}

b) \: v = whl \\  = 3 \times 4 \times 2 \\  = 24 {ft}^{3}

c) \: v =  \: whl\\ =  2 \times 7 \times 1 \\  = 14 {ft}^{3}

d) \: v = whl \\  = 3 \times 3 \times 3 \\  = 27 {ft}^{3}

If triangle ABC is defined by the coordinates A(-4, -4), B(2, -2), C(0, 4) is dilated by a scale factor of 1 2 , with resulting
PtichkaEL [24]

Answer:

  the origin, (0, 0)

Step-by-step explanation:

The coordinates of A' are 1/2 those of A, meaning each has been multiplied by the scale factor 1/2. When the dilated points are all the original points multiplied by the scale factor, the center of dilation is the origin.

_____

For center of dilation Q, the image of a point A after dilation by a factor of k is ...

  A' = kA + (k-1)Q

Then for points A, A', and dilation factor k, the center of dilation can be found to be ...

  (A' -kA)/(k-1) = Q

Here, that is ...

  Q = ((-2, -2) -(1/2)(-4, -4))/(1/2 -1) = (0, 0)/(-1/2)

  Q = (0, 0)
