Becky is typing an essay for her history class. The essay needs to be 4,300 words long. Becky can type 30 words per minute. If Becky has 700 words typed so far, how many hours will it take for Becky to finish typing the essay

2 HOUR AND 3 MINS

Step-by-step explanation:

He wrote 4300 words at the speed of 30 words per minute. But he had already wrote 700 words, so , now he is left with only 3700 words . so, he will write it in 123.3 mins which comes 2hour and 3 mins after rounding off.

2 hours

Step-by-step explanation:

Becky typing speed, 30 per min

She have alredy typed 700 words, that means the words that are left to type is 4300- 700 =3600

Therefkre the question is, how many minutes would it take for her to finish 3600 words

So the trick is

1min 30wordz

? 3600words

So u see the question mark? To get that, just use this trick

This shape "‍♂️" is multiply, this shape "‍♂️" is divide

Therefore in this case, take 3600 multiply 1min, divide 30, u will get 120min

Now your answer is 120min, or more specifically

2hours, since 1 hours = 60 minutes

a.   we have two

lines:   y = 4-x   and  

y = 8-x^-1

given two simultaneous equations that are both to be

true, then the solution is the points where the lines cross. the intersection is

where the two equations are equal. therefore the solution that works for both

equations is when

4-x = 8-x^-1

this is where the two lines will cross and that is the

common point that satisfies both equations.

b.   4-x = 8-x^-1

  x           4-x       8-x^-1

-3           7        

8.33

-2           6         8.5

-1           5         9

  0           4        

-

  1           3        

7

  2           2        

7.5

  3           1         7.67

the table shows that none of the x values from -3 to 3 is

the solution because in no case does

4-x = 8-x^-1

to find the solution we need to rearrange the equation to

find for x:

4-x = 8-x^-1

multiply both sides with x:

4x-x^2 = 8x-1

x^2+4x-1=0

x= -4.236, 0.236

therefore there are two points that satisfies the

equation.

find y:  

x=-4.236

y = 4-x   = 4 – (-4.236)

= 8.236

y = 8-x^-1 =   .236)^-1

= 8.236

x=0.236

  y = 4-x   = 4 – (0.236) = 3.764

y = 8-x^-1 =   8-(0.236)^-1

= 3.764

thus the two lines cross at 2 points:

(-4.236, 8.236) & (0.236, 3.764)

c.   to solve

graphically the equation 4-x = 8-x^-1

we would graph both lines: y = 4-x   and   y

= 8-x^-1

the point on the graph where the lines cross is the

solution to the system of equations.

just graph the points on part b on a cartesian coordinate

system and extend the two lines.   the

solution is, as stated, the point where the two lines cross on the graph.
