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'.
x = 4.777777778
Simplifying
x = 4.777777778

Which point on the coordinate plane below is (-9, 3)?
Point D
Point C
Point B
Point A
Answers
Answer:B
Step-by-step explanation: x is -9 and y is 3
Since it’s negative you’d go left by 9 blocks and the y is positive so you go up 3
Answer:
The answer is point B
Step-by-step explanation:
I know this because (-9, 3) seems to be located in quadrant 2 because in quadrant 2 along the x-axis it is negative and along the y-axis it is positive. So, when l look in quadrant 2 there seems to be only one point, point B, which if you look at it is 9 units to the left and 3 units upward.

erica planted 8 cucumber plants each plant had 37 green cucumbers how many cucumbers are on the 8 plants altogether
Answers
Answer:
296 Cucumbers
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.

Solve the system of equations using substitution.
y = -7x
2x - y = -9
Answers
Step-by-step explanation:
Since y= -7x you will want to substitute the y in the other equation.
2x -(-7x) = -9
2x + 7x = -9
9x = -9
so x will be -1
y= -7(-1)
x= -1
y= 7
Answer:
x = -1 , y =7 (-1,7)
Step-by-step explanation:
[tex]y=-7x\\2x-y = -9\\[/tex]
[tex]2x+7x = -9[/tex]
[tex]2x+7x = 9x\\[/tex]
[tex]9x = -9\\[/tex]
[tex]\frac{9x}{9} =\frac{-9}{9}[/tex]
[tex]x = -1\\[/tex]
[tex]y = -7(-1)\\y = 7[/tex]

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]
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!

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.
