please help me with this assignment
Step-by-step explanation:
Ok, so here are the basic steps of problem one:
P: Parenthesis. Flip both the negatives to positives: (6)to the 5th power X (6) to the 4th power.
E: Exponents: bring the first 6 to the 5th power: 6x6x6x6x6=7776 and the second to the 4th: 6x6x6x6=1296
M:Multiplication. Multiply 6 and 6 to get 10077696 (Thats you answer!)
what is an equation of the line that passes through the points (1,2) and (2,-1) 
Answer:
[tex]y = - 3x + 5[/tex]
You should also try solving it yourself to make sure I did not make any mistake.
Step-by-step explanation:
Equation
[tex]y = mx + b[/tex]
First we need to know the slope
[tex]slope = \frac{y1 - y2}{x1 - x2} [/tex]
[tex]slope = \frac{2 - ( - 1)}{1 - 2} = \frac{3}{ - 1} = - 3[/tex]
So far the equation will look like this
[tex]y = - 3x + b[/tex]
To get the b you insert a point into the equation like this. I picked point (1,2)
[tex]2 = - 3 \times 1 + b[/tex]
[tex]b = 5[/tex]
We could also check it with the other point and see if we get the same answer.
[tex] - 1 = - 3 \times 2 + b[/tex]
[tex]b = 5[/tex]
So the equation is
[tex]y = - 3x + 5[/tex]
Write the equation in Standard Form.
y=3/2x - 6
Answer:
3x - 2y = 12
Step-by-step explanation:
3x-2y=12 is the standard form of equation y=3/2x - 6
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The equation is y=3/2x - 6
y equal to three by two times of x minus six
y=3/2x - 6
LCM of 1 and 2 is 2
y=(3x-12)/2
Now apply cross multiplication
2y=3x-12
Two times of y equal to three times of x minus twelve
Now take 2y to RHS side
3x-2y-12=0
3x-2y=12
Hence 3x-2y=12 is the standard Form of equation y=3/2x - 6.

A cyclist estimates that he will bike 80 miles this week. He actually bikes 75.5 miles. What is the percent error of the cyclist's estimate? Round the percent to the nearest hundredth if necessary.
Answer:
6%
Step-by-step explanation:
Estimated distance = 80 miles
Actual distance covered = 75.5 miles
We need to find the percent error of the cyclist's estimate. Its formula is given by :
[tex]\%=\dfrac{|\text{actual value-estimated value}|}{\text{actual value}}\times 100[/tex]
Put all the values,
[tex]\%=\dfrac{80-75.5}{75.5}\times 100\\\\=5.96\%[/tex]
or
= 6%
So, the percentage error is 6%.
Answer:
5.96

*please be serious*
*solve for y*
Answer:
i cant answer it without x or at least some more stuff in the question, the only thing i can rlly say is 9x+2 maybe
Step-by-step explanation:
-8 (c - 10) = - (c-3)
1 Remove parentheses.
-8(c-10)=−c+3
2 Regroup terms.
-8(c-10)=3−c
3 Expand.
-8c+80=3−c
4 Add 8c8c to both sides.
80=3−c+8c
5 Simplify 3-c+8c to 3+7c
80=33+7c
6 Subtract 33 from both sides.
80-3=7c
7 Simplify 80-3 to 77.
77=7c
8 Divide both sides by 7.
77/7 = c
9 Simplify 77/7 to 11.
11=c
10 Switch sides.
c=11

The relationship between the number of hours a plumber works and the total work fee she charges is proportional. Her fee for 5 hours of work is $350.
Which of the following could be combinations of values for the plumber's work hours and total work fee she charges? There are 3 answers
Answer: As given, relationship between the number of hours a plumber works and the total work fee she charges is proportional.
The meaning of proportional is Ratio of number of hours a plumber works and the total work fee she charges is constant.
Using Unitary method
5 hours of work = $350
1 hours of work = $70
Let number of hours worked = x hours
Amount earned for x hours of work is represented by = $ y
For , x hours of work amount earned = 70 x (x=1,2,3...)
