Find the coordinates of the point which divides the join of (-1,7) and (4,-3) in the ratio 2:3 ?
Solution:-Let the given points be A(-1,7) and B(4,-3)
Now,
Let the point be P(x, y) which divides AB in the ratio 2:3
Here,
[tex] { \bf x \: = \frac{m_1 x_2 \: + \: m_1 x_1}{m_1 \: + \: m_2}} [/tex]Where,
[tex] m_1 [/tex] = 2 , [tex] m_2 [/tex] = 3
[tex] x_1 [/tex] = -1 , [tex] x_2 [/tex] = 4
[tex] \therefore [/tex] Putting values we get,
x = [tex] \frac{2 \: × \: 4 \: + \: 3 \: × \: -1}{2 \: + \: 3} [/tex]
x = [tex] \frac{8 \: - \: 3}{5} [/tex]
x = [tex] \frac{5}{5} [/tex]
x = 1
Now,
Finding y
[tex] { \bf y \: = \frac{m_1 y_2 \: + \: m_2 y_1}{m_1 \: + \: m_2}} [/tex]Where,
[tex] m_1 [/tex] = 2 , [tex] m_2 [/tex] = 3
[tex] x_1 [/tex] = 7 , [tex] x_2 [/tex] = -3
[tex] \therefore [/tex] Putting values we get,
y = [tex] \frac{2 \: × \: -3 \: + \: 3 \: × \: 7}{2 \: + \: 3} [/tex]
y = [tex] \frac{-6 \: + \: 21}{5} [/tex]
y = [tex] \frac{15}{5} [/tex]
y = 3
Hence x = 1, y = 3
So, the required point is P(x, y)
= P(1, 3)
The coordinates of the point is P(1, 3). [Answer]_______________________________________

Draw a line through the point (2, 2) with a slope of 1. Draw a line through the point (1,−1) with a slope of 1.
Answer:
should look like this
Step-by-step explanation:
equations are y=x and y = -x if needed
The equation of the lines are y = x and y = x - 2
A linear equation is given by:
y = mx + b;
where y, x are variables, m is the slope of the line and b is the y intercept
The equation of a line passing through the point (2, 2) with a slope of 1 is:
[tex]y-y_1=m(x-x_1)\\\\y-2=1(x-2)\\\\y = x[/tex]
The equation of a line passing through the point (1, -1) with a slope of 1 is:
[tex]y-y_1=m(x-x_1)\\\\y-(-1)=1(x-1)\\\\y = x-2[/tex]
Therefore both lines have equation of y = x and y = x - 2. The graphs of the lines are attached.

If a scattergraph contains points that do not fall in a perfect line: Multiple Choice a straight line can still be used to approximate the relationship if a general linear trend can be discerned. the relationship between the variables is not good enough to warrant fitting a line to the data. this is an indication that there is no relationship whatsoever between the variables. the visual fit method and high-low methods should not be used, but least-squares regression can be used.
Answer:
a straight line can still be used to approximate the relationship if a general linear trend can be discerned.
Step-by-step explanation:
The correct option is - A straight line can still be used to approximate the relationship if a general linear trend can be discerned.
Reason -
If a scatter graph contains points that do not fall in a perfect line, then a straight line can still be used to approximate the relationship if a general linear trend can be discerned.

How to solve systems of inequalities
Answer:
Determine whether an ordered pair is a solution of a system of linear inequalities.
Solve a system of linear inequalities by graphing
Solve applications of systems of inequalities
You can use desmos
Step-by-step explanation:
Graph x>2 on a number line.
Solve the inequality 2a<5a+12.
Determine whether the ordered pair \left(3,\frac{1}{2}\right) is a solution to the system \left\{\begin{array}{c}x+2y=4\hfill \\ y=6x\hfill \end{array}.
Determine Whether an Ordered Pair is a Solution of a System of Linear Inequalities
The definition of a system of linear inequalities is very similar to the definition of a system of linear equations.
System of Linear Inequalities
Two or more linear inequalities grouped together form a system of linear inequalities.
A system of linear inequalities looks like a system of linear equations, but it has inequalities instead of equations. A system of two linear inequalities is shown below.
\left\{\begin{array}{c}x+4y\ge 10\hfill \\ 3x-2y<12\hfill \end{array}
To solve a system of linear inequalities, we will find values of the variables that are solutions to both inequalities. We solve the system by using the graphs of each inequality and show the solution as a graph. We will find the region on the plane that contains all ordered pairs \left(x,y\right) that make both inequalities true.
Solutions of a System of Linear Inequalities
Solutions of a system of linear inequalities are the values of the variables that make all the inequalities true.
The solution of a system of linear inequalities is shown as a shaded region in the x-y coordinate system that includes all the points whose ordered pairs make the inequalities true.
To determine if an ordered pair is a solution to a system of two inequalities, we substitute the values of the variables into each inequality. If the ordered pair makes both inequalities true, it is a solution to the system. s

Locker ___ is bigger. Locker A has a volume of ___ cubic feet, while Locker B has a volume of 306 cubic feet.
Part B
The monthly rent for Locker A is $0.35 per cubic foot. The monthly rent for Locker B is $0.40 per cubic foot. How much does it cost to rent the largest locker each month?
___$
Answer:
Part A:
Locker A is bigger. Locker A has a volume of 324 cubic feet.
Part B:
$113.40 each month
Step-by-step explanation:
Part A
Locker A:
V = L(W)(H)
V = 6(6)(9)
V = 324
Part B
324(0.35) = 113.4
Locker A is bigger. Locker A has a volume of 324 cubic feet, while Locker B has a volume of 306 cubic feet.
Monthly rent for 324 cubic feet is $113.40
Calculation of VolumeStorage locker A is 6 feet wide, 6 feet deep, and has a height of 9 feet.
Volume of the cuboid is length times width times height
[tex]volume \; of \; locker \; A = lwh\\=6 \cdot 6 \cdot 9\\=324 cubic feet[/tex]
Volume of locker A is 324 cubic feet
Volume locker B is 306 cubic feet.
324 cubic feet is bigger thatn 306 cubic feet.
Locker A is bigger.
The monthly rent for Locker A is $0.35 per cubic foot. The monthly rent for Locker B is $0.40 per cubic foot.
Monthly rent for locker a is 0.35 per cubic feet.
Monthly rent for 324 cubic feet is [tex]324 \cdot 0.35 =113.4[/tex]

200+90 =290 m^3
Step-by-step explanation:
Find the volume of the box on the bottom
V = l*w*h
V = 8*5*5 = 200 m^3
Find the volume of the box on the top
V = l*w*h
V = 3*6*5 = 90 m^3
Add the volumes together to get the total volume
200+90 =290 m^3
Answer:
290m^3
Step-by-step explanation:
the rectangular prism on top: 3mx6mx5m = 90m^3
the rectangular prism on bottom: 5mx5mx8m = 200m^3
add both: 200m^3+90m^3 = 290m^3

(6b) Answer each question. Show your reasoning. 35% of f is 14. What is f? Round
to the nearest tenth.
Answer:
f = 40
Step-by-step explanation:
Rewrite 35% as 0.35, the equivalent decimal fraction.
Now let f be the original amount. 35% of this amount is 14:
0.35f = 14
Dividing both sides by 0.35, we get:
f = 14/0.35 = 40
f is 40
