Given line 1, with coordinates (-7,-3) and (4,7), and line
2 with coordinates (7,-7) and (-3, 4), find the slope of line 2
Answer:
-11/10 (fraction) or -1.1 (decimal)
Step-by-step explanation:
The slope formula is m=(y2-y1)/(x2-x1)
x1 = 7
x2 = -3
y1 = -7
y2 = 4
So, it’s: (4 - (-7))/(-3-7)
= (4+7)/(-3-7)
= (11)/(-10)
= -11/10 or -1.1

The water of a tank is initially 24 feet, and it is being
drained at a rate of 3 feet per day. The equation below
expresses the water level, y, in feet, in terms of the number
of days, x, since the tank began draining.
y = 24 - 3x
A scientist might be interested in the x-intercept of this
equation because it represents the moment when the tank
will be empty. Which of the following is the x-intercept of

A cylinder has the diameter 4 cm and is 3 cm high. What is the volume of the shape
(approximately)?
multiple choice question
28cm³, 38cm³ , 13cm³ 146cm³
Please hurry
Answer:
38cm³Step-by-step explanation:
diameter = 4cm
radius = 4/2 = 2cm
height = 3cm
volume of cylinder = π r²h
= 22/7 × 2 × 2 × 3
= 264/7 cm
= 37.714cm
The right answer is approximately 38cm³.Answer:
The answer( 38 cm^3)
Step-by-step explanation:
[tex]v = \pi {r}^{2} \times h \\ v = 3.14 \times {2}^{2} \times 3 \\ v = 37.699 \\ v = 38 \: {cm}^{3} [/tex]

Answer:
x = -5, and y = -6
Step-by-step explanation:
Suppose that we have two equations:
A = B
and
C = D
combining the equations means that we will do:
First we multiply both whole equations by constants:
k*(A = B) ---> k*A = k*B
j*(C = D) ----> j*C = j*D
And then we "add" them:
k*A + j*C = k*B + j*D
Now we have the equations:
-x - y = 11
4*x - 5*y = 10
We want to add them in a given form that one of the variables cancels, so we can solve it for the other variable.
Then we can take the first equation:
-x - y = 11
and multiply both sides by 4.
4*(-x - y = 11)
Then we get:
4*(-x - y) = 4*11
-4*x - 4*y = 44
Now we have the two equations:
-4*x - 4*y = 44
4*x - 5*y = 10
(here we can think that we multiplied the second equation by 1, then we have k = 4, and j = 1)
If we add them, we get:
(-4*x - 4*y) + (4*x - 5*y) = 10 + 44
-4*x - 4*y + 4*x - 5*y = 54
-9*y = 54
So we combined the equations and now ended with an equation that is really easy to solve for y.
y = 54/-9 = -6
Now that we know the value of y, we can simply replace it in one of the two equations to get the value of x.
-x - y = 11
-x - (-6) = 11
-x + 6 = 11
-x = 11 -6 = 5
-x = 5
x = -5
Then:
x = -5, and y = -6

Answer:
5 felt pads.
7 cards.
Step-by-step explanation:
Remark
The total number of items is 12 So let the felt sheets be xLet the cards = yEquations and Solution
x + y = 12
Now the price is 7.75 that she has to pay for the 12 items. She wants to come back with 0 dollars.
0.5x + 0.75y = 7.75 Multiply this equation by 2
x + 1.5y = 15.50 write the first equation underneath and subtract.
x + y = 12
.5y = 3 Divide by 0.5
y = 3/0.5
y = 7
So she can get 7 cards.
x + y = 12
x + 7 = 12
x = 12 - 7
x = 5
So she can buy 5 felt pads.

There is No solution for the system of Equations.
How to find the type of solution?There are three possible scenarios:
The lines intersect at a single point. The solution is the coordinates of the point of intersection. The lines are parallel and do not intersect, there is no common solution.The lines coincide with each other. and any point on the line satisfies both equations.If two lines on a graph are parallel, this means they have the same slope and they will never intersect. Therefore, there is no point of intersection, and the system of equations they represent has no solution. In other words, the system is inconsistent.
Geometrically, the fact that the lines are parallel indicates that they have the same rate of change and will never cross each other. In terms of the equations, this means that the system of equations has no common solution that satisfies both equations simultaneously.

A water tank already contains 56 gallons of water in Baxter begins to fill it. water flows into the tank at a rate of 8 gallons per minute. write a linear equation to model this situation. Find the volume of the water in the sink 5 minutes after Baxter begins filling the tank.
Answer:
Equation: y = 8x + 56
After 5 minutes, the volume of the water was 96 gallons
Step-by-step explanation:
Use y = mx + b to create the linear equation, where m is the slope and b is the y intercept.
Since the water flows in at 8 gallons per minute, 8 will be the slope. The variable x will represent the number of minutes.
There are already 56 gallons of water in the tank, so b will be 56.
Plug in these values into the equation:
y = 8x + 56
So, the linear equation is y = 8x + 56
Using this, plug in 5 as x to find the volume of the water in the sink after 5 minutes:
y = 8x + 56
y = 8(5) + 56
y = 40 + 56
y = 96
So, after 5 minutes, the volume of the water was 96 gallons
