y = 2x + 1
2x - y=3
Solve by substitution

Answers

Answer 1

Answer:

there is no solution

Step-by-step explanation:

y = 2x + 1

put into other equation

2x - 2x + 1 = 3

0x + 1 = 3

0x = 2

0/0x = 2/0

x = undefined

Jessica is selling books during the summer to earn money for college. She
earns a commission on
each sale but has to pay for her own expenses.
After a month of driving from neighborhood to neighborhood and walking
door-to-door, she figures out that her weekly earnings are approximately a
linear function of the number of doors she knocks on.
She writes the equation of the function like this: E(X) = 10x - 30, where x is the
number of doors she knocks on during the week and E(x) is her earnings for
the week in dollars.
Which of the following are reasonable interpretations of the y-intercept of
Jessica's function?
Check all that apply.
A. She can earn $10 per week even if she does not knock on any
doors.
B. She will lose $10 per week if she does not knock on any doors.
C. If she does not knock on any doors at all during the week, she will
lose $30.
D. Her expenses are $30 per week.

Angie has already written 19 pages, and she expects to write 1 page for every additional
hour spent writing. How many hours will Angie have to spend writing this week in order to
have written a total of 28 pages?

Answers

Answer:

[tex]9[/tex]

Step-by-step explanation:

[tex]28 - 19 = 9[/tex]

Answer:
9 hours

Explanation:
What we know:
- Angie has already written 19 pages
- Angies writes 1 page per hour

First, we can create the following equation to model this scenario:

Let x be equal to the number of hours that pass.
Total number of pages=1x+19

Now, because Angie wants to write 28 pages in total, we can plug that into the left side of the equation and solve for x, the number of hours.

28=1x+19
Subtract both sides by 19
28-19=1x+19-19
9=1x
x=9

Therefore, Angie would have to spend 9 hours to write a total of 28 pages.

I hope this helps!

what is the slope of negative 2y plus 6 equals 4x

Answers

Answer:

2

Step-by-step explanation:

The first step is to convert the equation to slope-intercept form (y = mx+b).

2y+6 = 4x

2y+6-6 = 4x-6

2y = 4x-6

2y/2 = 4x/2-6/2

y = 2x-3

In slope-intercept form (y = mx+b), m is the slope. 2 is m in the equation, so therefore it is the slope.

What is the value of the expression 3x+9 if x=6

Answers

Answer:

27

Step-by-step explanation:

3(6)=18

18+9=27

Answer:

27

Step-by-step explanation:

You would use PEMDAS to solve this equation, P (parenthesis) E (exponates)  M (multiply) D (divide) A (add) S (subtract). The way you use this is by following the steps in the order that you would spell PEMDAS, so 3x+9 would be 3•6+9. So look at the equation 3•6+9, so what would we use first? do we have parenthesis? No, Do we have exponents? No, Do we have multiplication?  Yes, so multiply 3 and 6 = 18. Now the equation will look like this 18+9 = 27.

Answers

Answer:-43 + 9x = 0

Step-by-step explanation:Simplifying

9x + -43 = 0

Reorder the terms:

-43 + 9x = 0

Solving

-43 + 9x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '43' to each side of the equation.

-43 + 43 + 9x = 0 + 43

Combine like terms: -43 + 43 = 0

0 + 9x = 0 + 43

9x = 0 + 43

Combine like terms: 0 + 43 = 43

9x = 43

Divide each side by '9'.

Step-by-step explanation:

I think it maybe 296 because since each plant produced 37 cucumbers and there are 8 plants you have to do 37 x 8 and you get 296.

Answer: 296

If you multiply the 37 green cucumbers each by the 8 cucumber plants they grew from, you'd end up with 296 green cucumbers altogether.

Answer:

416 in²

Step-by-step explanation:

Given that:

Height. h = 4 in

Length = 12 in

Width = 10 in

The surface area of a rectangular prism is obtained using the relation :

Surface Area, S = 2(lw + lh + wh)

S = 2[(10*12) + (10*4) + (12*4))

S = 2(120 + 40 + 48)

S = 2(208)

To decrease by 14% multiply by...

Answers

To decrease by 14% multiply by 0.86

The missing decimal number to decrease by 14% is 0.86.

What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

We are given that;

Percent= 14%

Now,

14% is equivalent to 0.14 as a decimal, and to decrease by 0.14 we need to subtract 0.14 from 1, which gives 0.86. So multiplying by 0.86 is the same as decreasing by 14%.

Therefore, by algebra the answer will be 0.86.

Since y= -7x you will want to substitute the y in the other equation.
