Answer:

x is -7.5  or -4.5

Answer:

y = 5x - 23

Step-by-step explanation:

Slope: 5

Point (4, - 3)

y-intercept: -3 - (5)(4)

= -3 -20 = -23

y = 5x - 23

Answer:

See below.

Step-by-step explanation:

x^2 - 6x + 1 = 0

x^2 - 6x = -1

We halve the coefficient of  x (which is -6/2 = -3) and square it, then add this to both sides:-

x^2 - 6x + (-3)^2 = -1 + (-3)^2

x^2 - 6x + 9 = -1 + 9

(x - 3)^2 = 8

x - 3 = ±√8

x =  3 ± √8

= 0.17, 5.83   to 2 decimal places.

Answer:

-30 - 15e

Step-by-step explanation:

given -7(3e + 4) + 6e - 2, we can distribute -7 to parenthesis

-21e - 28 + 6e - 2, then we add like numbers

-15e - 30

Answer:

-15e - 30

Step-by-step explanation:

-7(3e + 4) + 6e - 2

Simplify:

-21e + (-28) + 6e - 2       (distribute -7 to 3e + 4)

-21e + 6e - 28 - 2          (combine like terms)

-15e - 30                        (combine like terms)

Answer:

The answer is 3x3x3x3

Step-by-step explanation:

Reason: The 4 on top is an exponent. That exponent shows how many 3's you need to put. You need to put 4 3's, so 3x3x3x3

in order to find the answer to your questions you need to find the value

Example:

y+10=18

y=8

Answer:

The apple question is b and the bill question is a

Step-by-step explanation:

for the apple question you multiply 1.89 by 2.4 and round to the nearest 10th

for the bill question you divide 85.98 by 3 which gives you 28.66

Answer:

Step-by-step explanation:

Initial value is 20 as there are already 20 boxes ready for shipment.

Each hour 40 - 5 = 35 boxes are ready for shipment

The linear function for this case is:

35 is the slope or rate of change, 20 is the y-intercept.

y- the number of boxes ready for shipment after x hours.

Answer:

[tex]x = 88[/tex]

Step-by-step explanation:

the degrees of a triangle = 180. write an equation adding the angle measures given

[tex]48 + x - 44 + x = 180[/tex]

collect like terms on the left

[tex]2x + 4 = 180[/tex]

subtract 4 from both sides

[tex]2x = 176[/tex]

divide both sides by 2

[tex]x = 88[/tex]

Answer:

In the audience, there are 90 adults and 54 children

Step-by-step explanation:

If we have 5 adults for every 3 children, we would continue this pattern by saying we have 10 adults for every 6 children, 15 adults for every 9 children, and so on.

We can express this situation into an equation by saying 5x + 3x = 144

8x = 144

x = 18

So now we know there are 5(18) = 90 adults for every 3(18) = 54 children

In the audience, there are 90 adults and 54 children

Answer:

In the audience, there are 90 adults and 54 children

Answer:

20%

Step-by-step explanation:

First you must find the difference between the original price ($26.95) and the discounted price ($21.56)

26.95-21.56=5.39

Second find x

% of = #*x

Meaning

5.39=26.95*x

Divide 5.39 by 26.95

0.2=x which equals 20%

Answer:

8

Note: I got it right on the same test you took as me.

The value of time period for the equation is 8.

A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.

For the given situation,

The population of insects is increasing by 9% each week = 0.09

At the beginning of the experiment, number of insects = 16

Number of insects increased per week

⇒ [tex]16+16(0.09)[/tex]

Let the time period be x.

Number of insects increased after 8 weeks can be found by the equation,

[tex]Future Amount = 16 (1 + 0.09)^{x}[/tex]

⇒ [tex]Future Amount = 16 (1 + 0.09)^{8}[/tex]

Hence we can conclude that the value of time period for the equation is 8.

Step-by-step explanation:

By BODMAS rule,

B - Brackets

O - Orders

D - Division

M - Multiplication

A - Addition

S - Substraction

Consider DMAS alone.

Here, there is no division.

So,

Multiplication ( x ) should be the first step.
