Answer:
equation: y = -6x -20
Step-by-step explanation:
pass (0,-20) (-10,40)
y = mx + b
y intercept (b) = -20
slope (m) = (40 - -20) / (-10 - 0) = 60 / -10 = - 6
equation: y = -6x -20

B. If two points on a line are A(11, - 1) and B(13, 3) , what is the equation of the line in point -stope form ?
Given:
Two points on a line are A(11, - 1) and B(13, 3).
To find:
The point slope form of the line.
Solution:
Point slope form: If a line passes through two points [tex](x_1,y_1)\text{ and }(x_2,y_2)[/tex], then the point slope form of the line is
[tex]y-y_1=m(x-x_1)[/tex]
where, m is slope, i.e., [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex].
Two points on a line are A(11, - 1) and B(13, 3). Slope of the line is
[tex]m=\dfrac{3-(-1)}{13-11}[/tex]
[tex]m=\dfrac{3+1}{2}[/tex]
[tex]m=\dfrac{4}{2}[/tex]
[tex]m=2[/tex]
The slope of the line is 2 and it passing through (11,-1). So, the point slope form is
[tex]y-(-1)=2(x-11)[/tex]
[tex]y+1=2(x-11)[/tex]
Therefore, the required point slope form is [tex]y+1=2(x-11)[/tex].

We are to find the quotient as shown:
[tex]= \frac{n+3}{2n-6} \div \frac{n+3}{3n-9} \\\\= \frac{n+3}{2n-6} \times \frac{3n-9}{n+3} \\\\= \frac{n+3}{n+3} \times \frac{3n-9}{2n-6}\\\\= 1 \times \frac{3(n-3)}{2(n-3)}\\\\= 1 \times \frac{3}{2} \\\\= \frac{3}{2}[/tex]

A. No solution
B. One solution
C. Infinitely many solutions
D. Impossible to determine
Answer:
infinitely many solutions
There are ''Infinitely many solutions'' in this system of equations.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The system of equations are,
⇒ y = -2x + 2 .. (i)
⇒ 2y + 4x = 4 .. (ii)
Now, Solve the expression as;
Multiply by 2 in (i);
⇒ 2y = 2 (-2x + 2)
⇒ 2y = -4x + 4
⇒ 2y + 4x = 4
Clearly., Both equations are same.
Hence, There are ''Infinitely many solutions'' in this system of equations.

does anyone know how to solve 2x+3y=7 and 4x-5y=25 using substitution to solve the system of equations. PLEASE HELP ONLY IF YK IT
Answer:
Step-by-step explanation:
first, let us mark the two equations as i and ii
2x+ 3y = 7
or, 2x = 7-3y
or, x = (7-3y) ÷ 2.........................(i)
and let 4x-5y= 25............(ii)
Now, put the the value of x from (i) into (ii)
4[(7-3y) / 2] -5y = 25
2(7-3y) -5y = 25
14- 6y - 5y = 25
-11y = 11
y = -1
Now, put y = -1 back in (i)
x = (7-3y)/2
x = 10 /2
x = 5

Answer:
10N to the left
because theres 50N to the right and 60N to the left, the 50 to the right cancels out 50 to the left, leaving you with 10N to the left, or A
Step-by-step explanation:
I hope this helps :)
Answer:
A. 10 N to the left
Step-by-step explanation:
The way you would answer these questions are subtraction or addition. For example, if they are both pulling and pushing to the left it would be 60+30+20=110.
However, it is not. It pulls 30+20N to the right which would be 50N.
Then it pulls 60N to the left
So we have 60N to the left and 50N to the right. Therefore, we would subtract them.
60-50
10
Since 60 goes to the left and was bigger therefore, I would be
A. 10 N to the left.
solve x + 4y = 14 and 3x + 3y = 15 by elimination
Answer:
you have to subtract 3y and then you do the same on the other side, then you end up with two numbers where you divide them and that will be your result
Step-by-step explanation:
Answer:
(2, 3 )
Step-by-step explanation:
Given the 2 equations
x + 4y = 14 → (1)
3x + 3y = 15 → (2)
Multiplying (1) by - 3 and adding to (2) will eliminate the x- term
- 3x - 12y = - 42 → (3)
Add (2) and (3) term by term to eliminate x, that is
0 - 9y = - 27
- 9y = - 27 ( divide both sides by - 9 )
y = 3
Substitute y = 3 into either of the 2 equations and solve for x
Substituting into (1)
x + 4(3) = 14
x + 12 = 14 ( subtract 12 from both sides )
x = 2
solution is (2, 3 )

RT = 10
Step-by-step explanation:
Since, U and V are the midpoints of the segments RS and ST respectively.
Therefore,
By Mid-segment Theorem:
RT = 2UV
4x - 22 = 2(10x - 75)
4x - 22 = 20x - 150
150 - 22 = 20x - 4x
128 = 16x
128/16 = x
8 = x
x = 8
RT = 4x - 22 = 4*8 - 22 = 32 - 22 = 10
1. During the breakfast service, the D-Town Diner sells 12 cups of
coffee for every 10 glasses of orange juice. How many cups of coffee
would the diner have sold if 40 glasses of orange juice had been sold?
Complete the table with equivalent ratios.
The number of cups of coffee restaurant sold for 40 glasses of orange juice had been sold is 48.
What are proportions?The word "proportion" generally refers to an amount that is divided into parts or shares. Two ratios are in proportion when they are equal, as stated by the definition of proportion. An equation or a statement that says anything to that effect means that two ratios or fractions are equal.
Given that, the D-Town restaurant sold 12 cups of coffee for every 10 glasses of orange juice.
So, the ratio of cups of coffee to glasses of orange is 12:10
The restaurant have sold 40 glasses of orange juice.
Let c number of coffee cups are sold for 40 glasses of orange juice.
So, the ratio is c:40
Then, the proportion (ratios are equal) is 12:10::c:40
10c=480
c=48
Therefore, the number of cups of coffee restaurant have sold for 40 glasses of orange juice had been sold is 48.

what is 592 .962 rounded to the nearest tenth
Answer:
593.0
Step-by-step explanation:
If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.
The 9 is in the tenth place, so we look to the 6 to find the answer. Since 6 is over 5, we will round up. The number after .9 is 1.0, but 1.0 cannot fit in one decimal place. So then, you add the 1.0 to the 592 to get 593.0

Mr. Irvine and Mr. Babyak left in separate cars at the same time on the same road , to see the Nascar Race in Dover, Delaware. Mr. Irvine drove 77mi/h and Mr. Babyak drove 71 mi/h. In how many hours will they be 18 miles apart?
Answer:
In 3 hours, they will be 18 miles apart.
Step-by-step explanation:
Given that:
Speed of Mr. Irvine = 77mi/h
Speed of Mr. Babyak = 71mi/h
Distance to be apart = 18 miles
Let,
t be the time.
We will subtract the speeds as both the cars are driving in the same direction.
Distance = Speed * Time
18 = (77-71)t
18 = 6t
6t = 18
Dividing both sides by 6
[tex]\frac{6t}{6}=\frac{18}{6}\\t=3[/tex]
Hence,
In 3 hours, they will be 18 miles apart.
