Group of answer choices A. (5, 1) B. (-1, -7) C. (-4, -1) D. (-1, -4)
Answer:
C
Step-by-step explanation:
Label the two equations:
-2x -y= 9 -----(1)
2x -9y= 1 -----(2)
(1) +(2):
-2x -y +2x -9y= 9 +1
-2x +2x -y -9y= 10
Simplify:
-10y= 10
y= 10 ÷(-10)
y= -1
Substitute y= -1 into (2):
2x -9(-1)= 1
2x +9= 1
2x= 1 -9
2x= -8
x= -8 ÷2
x= -4
Thus, the solution is (-4, -1).
What is the equation of the line that passes through the point ( 2 , − 3 ) (2,−3) and has a slope of 2
Answer: y = 2x -7
Step-by-step explanation:
The equation of a line is in the form y = mx + b
We know m = 2
So, y = 2x + b
we need to find b, and we can use either point given to find it:
lets use (2, -3):
-3 = 2(2) + b
-7 = b
now we know, the line's equation is y = 2x -7
what is 36 more than 40
Answer:
76.
Step-by-step explanation:
Forty "more" implies that you are adding forty to thirty-six. Making it seventy-six.
The number that is 36 more than 40 will be 76.
What is Algebra?Algebra is the analysis of abstract symbols, while reasoning is the manipulation of all those views.
The definition of unsophistication is making something simpler to achieve or grasp while also making it a little less difficult.
Let 'x' be the number that is 36 more than 40. Then the equation is given as,
x = 36 + 40
Add the number 36 and 40, then we have
x = 36 + 40
x = 76
The number that is 36 more than 40 will be 76.

hi! what’s the square root of 82 rounded to the nearest tenth?
Answer:
9.1
Step-by-step explanation:
I went into my calculator and typed in [tex]\sqrt{82}[/tex] and I was given:
9.055385...
So to round the nearest tenth, you look at the tenths place (which is 0) and go one number behind that (which is 5). Since the number behind the tenths place is 5 or higher, you round up to 1
If we drop a rock near the surface of Earth, its velocity increases by 32 feet per second for each second the rock falls. Is the velocity of the rock a linear function of the time since it was dropped?
The velocity of the rock is the number of feet traveled per second
The velocity of the rock is a linear function of time
How to determine the function?From the question, we understand that the velocity increases by 32 feet per second for each second
This means that we have the following rates:
Velocity = 0, 32, 64, 96, 128....
Notice that the difference between adjacent numbers is 32.
This means that the velocity changes at a constant rate or slope
Hence, the velocity of the rock is a linear function

Eric jog 3 1\4 miles on Monday 5 5\8 miles on Tuesday and 8 miles on Wednesday suppose he continues the pattern for the remainder of the week how far will Eric jog on Friday
Step-by-step explanation:
first, let's bring everything to the same fraction denominator, which would be 1/8 to cover all.
so, he jogs
3 2/8 miles on Monday
5 5/8 miles on Tuesday
8 0/8 miles on Wednesday
the difference from day to day is
5 5/8 - 3 2/8 = 2 3/8 (subtract the whole numbers and then also the fractional part).
to control :
5 5/8 + 2 3/8 = 7 8/8 = 8
so, he adds every day 2 3/8 miles.
that means in 2 days (from Wednesday to Friday) this will be additional 2×(2 3/8) = 4 6/8 = 4 3/4 miles.
so, he will jog
8 + 4 3/4 = 12 3/4 miles
on Friday.
don't forget, when we write something like 2 3/8. we actuality mean (2 + 3/8). and all rules about handling, transforming and calculating expressions apply.
therefore, e.g
2×(2 3/8) = 2×(2 + 3/8) = 4 + 6/8 = 4 6/8 = 4 3/4

Which of the following is the graph of an odd-degree polynomial with a positive lead
coefficient?
(Answer choices are in the image)
The third graph is the only one that is an an odd-degree polynomial with a positive lead coefficient.
How to Interpret the graph of a Polynomial?An even number of total minimums/maximums of the Polynomial is classified as an odd-degree polynomial. Now, we see that only the 3rd and 4th graphs are odd-degree polynomials because they have four total minimums/maximums.
For the polynomial to have a positive leading coefficient, the line must go up in the positive direction. This means that only the 1st and 3rd graphs have a positive leading coefficient due to the fact that their right-most line is going upwards.
Thus, we can say that the third graph is the only one that is an an odd-degree polynomial with a positive lead coefficient.

It begins to decrease at the rate of $0.14 each hour. If the two rates continue, in how many hours will the prices of the two stocks be the same?
Answer:
1.50 Hours
Step-by-step explanation:
Given:
→ The price of Stock A at 9 A.M. was $12.41. → Since then, the price has been increasing at the rate of $0.12 each hour. → At noon the price of Stock B was $13.16. → It begins to decrease at the rate of $0.14 each hour.To Find:
If the two rates continue, in how many hours will the prices of the two stocks be the same?
Solve:
Price of stock A at 9 a.m.= $12.41
The price has been increasing at the rate of $0.12 each hour.
Increase in price after 3 hours = 0.12 × 3 = 0.36
Price of Stock A at noon= 12.41+0.36 =12.77
Let n be the no. of hours after which the prices of both the stocks will be same .
So, Increase in price after n hours = 0.12 n
Price of Stock A after n hours = 12.77+0.12 n
Price of stock B = 13.16
The price has been decreasing at the rate of $0.14 each hour.
Let n be the no. of hours
So, Increase in price after n hours = 0.14 n
Price of Stock B after n hours =13.16-0.14 n
ATQ
12.77 + 0.12n = 13.16 - 0.14n
-12.77 + 13.16 = 0.12n + 0.14n
0.39 = 0.26n
0.39/0.26 = n
n = 1.50
Hence the prices of the two stocks be the same after 1.50 hours after 12 pm .
