Answer:

[tex]x \le -4[/tex]

Step-by-step explanation:

Given

[tex]\qquad16x - 7 \leq -71[/tex]

Required

Solve

Start by adding 7 to both sides

[tex]\qquad16x - 7 + 7 \leq -71 + 7[/tex]

[tex]\qquad16x - 7 + 7 \leq -64[/tex]

[tex]\qquad16x \leq -64[/tex]

Divide both sides by 16

[tex]\frac{16x}{16} \leq \frac{-64}{16}[/tex]

[tex]\frac{16x}{16} \leq -\frac{64}{16}[/tex]

[tex]x \leq -\frac{64}{16}[/tex]

[tex]x \le -4[/tex] --- The solution

1. (-3,3 ½)

2. (2.9,1) or (2 9/10,1)

3. (-1,-2.5) or (-1,2 1/2)

4. (1.9,-1) or (1 9/10,-1)

Step-by-step explanation:

Since some points were not directly on a line, they must have not been a whole number, so I estimated and used logical reasoning to get the coordinates of the items. Hope this helps.

Answer:

  3)  1,440

Step-by-step explanation:

The dimensions of the prism can be expressed in terms of the cube dimensions.

  1 2/6 inches = 8/6 inches = 8×(1/6 inch)

  5/6 inch = 5×(1/6 inch)

  6 inches = 36/6 inches = 36×(1/6 inch)

So, the volume of the prism in terms of small cubes is ...

  8×5×36 = 1,440 . . . small cubes

Answer:

Value of p = 30

Step-by-step explanation:

Given:

Two number = 20 , p

Highest common factor (HCF) = 10

Lowest common multiple (LCM) = 60

Find:

Value of P

Computation:

Product of two number = HCF x LCM

20 x p = 10 x 60

20 p = 600

p = 600 / 20

Value of p = 30

Answer:

3i[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Using the rule of radicals

[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex] and [tex]\sqrt{-1}[/tex] = i

Given

[tex]\sqrt{-27}[/tex]

= [tex]\sqrt{9(3)(-1)}[/tex]

= [tex]\sqrt{9}[/tex] × [tex]\sqrt{3}[/tex] × [tex]\sqrt{-1}[/tex]

= 3i[tex]\sqrt{3}[/tex]

Answer:

x=3

Step-by-step explanation:

log (x^2 - 1) - log (2x + 2) = 0

Add log (2x + 2) to each side

log (x^2 - 1) = log (2x + 2)

Since the logs with the same base are equal the x^2 -1 must equal 2x+2

x^2 -1 = 2x+2

Subtract 2x+2 from each side

x^2 -1 -2x-2 = 2x+2 -2x-2

x^2 -2x-3 = 0

Factor

What number multiplies to -3 and adds to -2

-3 *1 =-3

-3+1 =-2

(x-3) (x+1) =0

Using the zero product property

x-3 =0   x+1 =0

x=3  x=-1

Check to see if solutions are valid

x = -1

log ((-1)^2 - 1) - log (2*-1 + 2) = 0

log(0) - log 0 = 0

Log 0 is undefined  x =-1 not a valid solution

x = 3

log ((3)^2 - 1) - log (2*3 + 2) = 0

log(8) - log 8 = 0

valid

Answer:

Therefore, the rate of change of function 2 is 3 more than the rate of change of function 1.

Hence, option C is true.

Step-by-step explanation:

Function 1

A horizontal straight line is drawn joining the ordered pairs (0, 3) and (4, 3).

Given the points

It means

at x = 0, y = 3

at x = 4, y = 3

Since the y-values are same, it means the points lie on a horizontal.

The rate of change or slope of a horizontal line is zero because it does not rise vertically ( i.e. y₁ - y₂ = 0).

Therefore, the rate of change of function 1 = 0

Function 2

y = 3x+1

comparing with the slope-intercept form

y = mx+b      

here m is the rate of change or slope and b is the y-intercept

so the rate of change of the function 2 = m = 3

Conclusion:

Therefore, the rate of change of function 2 is 3 more than the rate of change of function 1.

Hence, option C is true.

Answer:

d^5

Step-by-step explanation:

Given the indicinal expression

d^8/d^3

Based on the law of indices, if the base are the same, subtract the powers. This is as shown:

d^8/d^3 = d^{8-3}

d^{8-3} = d^5

Hence the solution is d^5

Answer:

243 .....................

Answer:

Step-by-step explanation:

ln(x-2)^5

ln(x + 3)^8

ln(x + 3)^3

(x - 2)^5 * (x + 3)^8

================            Cancel the (x + 3)s

(x + 3)^3

(x- 2)^5 * (x + 3)^5

( (x - 2) *(x + 3) )^5

ln( (x - 2)(x + 3)^5   You could expand what's in the brackets.

ln( x^2  - 2x + 3x - 6)^5

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

the answer all depends on what you are given. If this answer proves to be wrong, write me a note under comments and I'll alter my answer.

Answer:

Because if you add 18x to both sides of the equation, you get 0 = -18

Step-by-step explanation:

When you combine like terms in the equation, you get -18x = -18x - 18. After adding 18x to both sides, you have 0 = -18. This is not true, which means that there are no solutions to the equation.

Answer:

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

Step-by-step explanation:

Given

y = 3x - 2 ( add 2 to both sides )

y + 2 = 3x ( isolate x by dividing both sides by 3 )

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

Step-by-step explanation:

Answer:

given below

Step-by-step explanation:

These are fractions problems .

If you have 12 eggs and you need 1/6 then

12* 1/6= 12/6= 2 eggs

Similarly if you need 1/3,1/4, 1/2

12 * 1/3= 12/3= 4 eggs

12 * 1/4 = 12/4= 3 eggs

12 * 1/2 = 6 eggs

These can be drawn in sets of 12.

from the picture we see that dividing the 12 eggs in two parts and coloring one part gives 6 eggs.

Similarly dividng the 12 eggs in three parts and coloring one part gives 4 eggs.

The fractions 1/3,1/4,1/2 or 1/6 means dividing the 12 eggs into 3,4,2, or 6 parts and obtaining 1 part out of it.

------------------------

The y value in the table gets multiplied by 4 every time the x value goes up by 1. You can check your work using the values in the table given to you. 0.25 times four is 1. 1 times four is 4, and so on as the table goes.

The ratio would be written as 1:4
