Answer:

-14g-84/6

Step-by-step explanation:

multiply the numbers

7/2 (-4-1 · 2/3g)

7/2(-4-2/3g)

combine multiplied terms into a signle fraction

7/2(-4-2/3g)

7/2(-4+-2g/3)

find common denominator

7/2(-4+-2g/3)

7/2(3(-4)/3+-2g/3)

combine fractions with common denominator

7/2(3(-4)/3+-2g/3)

7/2(3(-4)-2g/3)

multiply the numbers

7/2(3(-4)-2g/3)

7/2(-12-2g/3)

rearrange terms

7/2(-12-2g/3)

7/2(-2g-12/3)

combine multiplied terms into a single fraction

7/2 · -2g-12/3

7(-2g-12)/2 · 3

distribute

7(-2g-12)/2 · 3

-14g-84/2 · 3

Answer:

Step-by-step explanation:

(a) Solving the x-equation for u gives ...

  u = (x -1)/4

Differentiating both equations with respect to u, we have ...

  dy/du = 1 -4u

  dx/du = 4

Then dy/dx is ...

  dy/dx = (dy/du)/(dx/du) = (1 -4u)/4

Substituting for u gives ...

  dy/dx = (1 -4(x -1)/4)/4

  dy/dx = (2 -x)/4

__

(b) The approximate change in y is ...

  ∆y ≈ (dy/dx)(∆x)

For ∆x = 2.98 -3.00 = -0.02, and x=3, the approximate change is ...

  ∆y ≈ (2 -3)/4(-0.02)

  ∆y ≈ 0.005

Answer:

Two shirts can be made

Step-by-step explanation:

We do have 3/4c of orange dye.

We do require 3/8c per T-shirt.

But, using math, it can be shown that 3/4c=2×3/8c

Looking at it this way: 3/4c = 2x3/8c

Where the 2 is the number of T-shirts we can produce.

It is easy now to see: 3/4c = 2x3/8c = 6/8c

So: 34c=68c=34c→ and all of this is orange dye

Answer:

10, 4, -1

Step-by-step explanation:

10×4=40

40×-1=-40

-40=-40

The three integers could be 8, -5, and 1.

A number without a decimal or fractional element is known as an integer, which can be both positive and negative, including zero.

Given that, the product of three integers is -40.

Since the product is negative, there should be at least one negative number.

The three numbers can be 8, -5, and 1.

8 × (-5) ×1 = -40

Hence, the three integers could be 8, -5, and 1.

Answer:

y=8x+3

Step-by-step explanation:

to check plug the numbers to the equation and you will that it is right

Answer:

f(x) = 8x + 3

Explanation:

I knew f(x) = mx +b is the formula for a linear equation and that when x = 0,

f(x) = b

So, when x = 0 in the table, f(x) = 3 and therefore b = 3

Now we can plug in f(x) = 11 and x =1 into f(x) = mx+b along with our b value

11 = m(1) + 3

solving for m we get m  =  8 which finishes our unknowns

f(x) = mx + b

f(x) = 8x + 3

Answer:

64

Step-by-step explanation:

Let the missing side be " x "

30 /  ( 30 + 10 ) = 48 / x.

30 / 40 = 48 / x

3 / 4 = 48 / x

3 * x = 4 * 48

x = 4 * 48 / 3

  = 4 * 16

x = 64
