ALGEBRA STUFF IS ANNOYING

Answer: Explanation below.

Step-by-step explanation:  A good question, since working with inequalities  and using the same operations as with "=" equations is a bit uncomfortable.  I don't have a mathematical proof for this operation, but approach it with a "Why not?" attitude.  If 9>6 and 130 > 30, why wouldn't 139>36?  There is nothing in the add operation that should upset the basic inequality.  I suggest https://www.storyofmathematics.com/inequalities-math for more information.

Answer:

8

Step-by-step explanation:

f(x) = 2x

f(0) = 2 * 0 = 0

f(1) = 2 * 1 = 2

f(2) = 2 * 2 = 4

f(3) = 2 * 3 = 6

f(4) = 2 * 4 = 8

The complete table of the linear function f(x) = 2x for x = 0 to 4 is:

x     0   1    2   3  4  

f(x)  0   2   4   6   8

The function is given as:

f(x) = 2x

When x = 0, we have:

f(0) =2(0) = 1

When x = 1, we have:

f(1) =2(1) = 2

When x = 2, we have:

f(2) =2(2) = 4

When x = 3, we have:

f(3) =2(3) = 6

When x = 4, we have:

f(4) =2(4) = 8

So, the complete table is:

x     0   1    2   3  4  

f(x)  0   2   4   6   8

Answer:

its 10w-3t+5

Step-by-step explanation:

The cost of pen and colored pencils per piece is =10.85

The new total length of both Betty and Beth is =227.2cm

Total number of pens Randy needs to buy = 5

Total number of colored pencils Randy needs to buy= 3

The both items are bought at the same prize = a

The cost of five pens is = 5× a = 5a

The cost of colored pencils is = 3 × a= 5a

The money needed to spend on the items= 86.78

To find the cost of each item which is a ,

5a + 3a = 86.78

(5+3) a= 86.78

8a = 86.78

therefore a = 86.78/8

= 10.85

Therefore the prize of each item is = 10.85. That is option B

Betty's height = 119.2 cm

Beth's height = 105.6cm ( which remained the same)

But Betty's height after 6 months = (6× 0.4) + 119.2

= 2.4 + 119.2

= 121.6 cm

Therefore, the total new height= 121.6 + 105.6

= 227.2cm

That is option A.

Answer:

Step-by-step explanation:

AB=6 cm

BX=1/2 AB=1/2 ×6=3 cm

BC=8 cm

BY=1/2×BC=1/2×8=4 cm

perpendicular bisector of a chord always passes through the center.

so quadrilateral OXBY is a rectangle.

Perimeter=2(BX+BY)=2(3+4)=2×7=14 cm.

Answer: x = -28

Step-by-step explanation:

1) Distribute

3(x-8)+4x=8x+4

3x-24+4x=8x+4

2) Combine like terms

7x - 24 = 8x + 4

3) Move x(subtract 7x from both sides)

-24 = x + 4

4) Subtract 4 from both sides.

-28 = x

Hope it helps :)

The simplified solution of the given expression is x = -28.

Given that, to determine the simplified solution of the expression  3(x-8)+4x=8x+4

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
3(x-8)+4x=8x+4
3x - 24 + 4x - 8x = 4
-x = 4 + 24
-x = 28

Thus, the simplified solution of the given expression is x = -28.

Answer:

X < 6

Step-by-step explanation:

Since 6 times 6 = 36, then for this equation to be true, x would have to be less than 6.

Answer:

[tex]y = \frac{1}{4} x + 6[/tex]

Step-by-step explanation:

rewrite the original equation

[tex]4x + y = 7 \\ y = - 4x + 7[/tex]

perpendicular line has a negative reciprocal slope. I will use this slope and substitute the points to find our y-intercept

[tex]5 = \frac{1}{4} ( - 4) + b \\ 5 = - 1 + b \\ b = 6[/tex]

Answer:

y = 3x + 3

Step-by-step explanation

Values on the y-axis are increasing by 3, while values on the x axis are increasing by 1, so the slope is 3/1 or just 3

To find b, you the slope, 3, from the 6. You also subtract 1 from 1 in the x-collum. You do this to find the y-intercept, or when x=0.

Given the value of the standard deviation of  population, if the critical value is 0.65, the Margin of error will be 0.65.

Margin of error simply shows how many percentage points a results will differ from the real population value.

It can be expressed as;

Margin of error = Critical value × Standard deviation

Given that;

Margin of error = Critical value × Standard deviation

Lets take critical value to be 0.05

Hence,

Margin of error = 0.05 × 13

Margin of error = 0.65

Therefore, given the value of the standard deviation of  population, if the critical value is 0.65, the Margin of error will be 0.65.
