The slope intercept form is y= ( -3/2 ) x + 7/2
What is slope ?
A line's steepness is determined by its slope. In mathematics, slope is determined by "rise over run" (change in y divided by change in x).
(x1,y1)= (3. -1) and (x2,y2)= (5, -4)
slope intercept form:
y=mx+b , m=slope, b = constant
m= (y2-y1) /( x2-x1) = (-4-(-1)) / ( 5-3) = -3/2
line equation:
y-y1=m(x-x1)
Substitute the values
y-(-1)=( -3/2 ) (x-3)
y+1=( -3/2 ) x + 9/2
y= ( -3/2 ) x + 9/2 - 1
y= ( -3/2 ) x + 7/2
Thus, the slope intercept form is y= ( -3/2 ) x + 7/2

a racing venue wants to make the charity race 5% longer. If the race was 25km, what is the new race length
The length of the racing venue after the increase of 5 % is 26.25 km
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the increased length of the racing venue be = A
Let the total length of the racing venue be = 25 km
The percentage increase in the length of the racing venue = 5 %
So , the equation will be
Increased length of the racing venue = total length of the racing venue + ( percentage increase in the length of the racing venue x total length )
Substituting the values in the equation , we get
Increased length of the racing venue = 25 + ( 5/100 ) x 25
Increased length of the racing venue = 25 + ( 5/4 )
Increased length of the racing venue = 25 + 1.25
Increased length of the racing venue = 26.25 km
Therefore , the value of A is 26.25 km
Hence ,
The length of the racing venue after the increase of 5 % is 26.25 km

Mi-Cha and her friends are going to a bounce music festival in New Orleans.
They decide to buy hoodies at the festival. A table showing the relationship between the number of hoodies and the total cost of the hoodies is shown.
The total cost is 16 times greater than the number of hoodies, hence option A is correct.
What is the average cost of an item?
The average price of products and services is the average cost. The average of these numbers will provide the average cost price when we have a number of nearly identical things to sell or purchase. It facilitates the purchasing and selling procedure for store owners.
The average cost is calculated as the sum of all product costs divided by the total number of goods. The word "average" is also used in math. The term "mean of data" refers to the average of any given set of data. The average, however, is thought to be the appropriate term in corporate contexts where profit and loss are crucial elements.
Given that,
1 hoodie costs $16
2 hoodies cost $32
3 hoodies cost $48
4 hoodies cost $64
5 hoodies cost $80
Thus, the relation between total cost and the number of hoodies can be found be dividing the cost upon the number of hoodies
∴ The relation = $80/5
Hence, cost of a hoodie is $16
We can say that option A, the total cost is 16 times greater than the number of hoodies.

Step-by-step explanation:
Since line MU = line MV, therefore line UV = 2 line MU.
Since line UL = line LT, therefore line UT = 2 line LT.
Now we know triangle MUL and triangle VUT are similar using SAS by a scale factor of 2. Since line TV is double the length of line ML.

The required equation of the line is given as y = 5x -6.
To determine the equation of a line passing through the point (-4, -11) and perpendicular to the line 4x + 5y = -45.
What is the slope of the line?The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,

The coordinates of C are (-6, -4) if B is the midpoint of AC and the coordinates of A and B are (2, 8) and (-2, 2).
What is a mid-point in coordinate-geometry?The midpoint of the line segment is what the term "midpoint theorem" in coordinate geometry refers to. You can determine it by averaging the coordinates of the specified endpoints, which defines the coordinate locations of the line segment's midway. In order to get the intersection of the two provided points, the midpoint formula is employed.
Given,
B is the midpoint of AC.
The coordinates of A are (2, 8)
The coordinates of B are (-2, 2)
Here,
We have to find the coordinates of C
We need check the options of C and find the midpoint of A and C
If we get the midpoint same as the coordinates of BC
Then our answer is correct.
First we have to check option A:
A(2, 8) and C(-6, -4)
Midpoint of B(x, y)=((x₁+x₂)/2 , (y₁+y₂)/2)
B(x, y)=((2-6)/2 , (8-4)/2)
=(-2, 2)
So, the coordinates of B are (-2, 2)
So, our choice is correct.
Therefore, the coordinates of C are (-6, -4)
Hence, option A is correct.

Car X travels miles in 3 hours. a. Write the equation of the line that describes the relationship between distance and time. Use x for the time in hours and y for the distance in miles. b. What is the graph that represents the relationship between distance and time for Car X? Explain. Question content area bottom Part 1
The required equation would be y = 48x which describes the relationship between distance and time, where x is for the time in hours and y is for the distance in miles.
Car X travels 144 miles in 3 hours.
X represents the time in hours and y represents the distance in miles.
Move 3 units to the right of the origin using the slope and
144 unit(s) up to locate the spot
(3,144), which may be used to plot the connection.
Let the required linear equation be y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]
x₁ = 0, y₁ = 0
x₂ = 3, y₂ = 144
⇒ y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]
Substitute values in the equation, we get
⇒ y - 0 = (144 - 0)/(3 -0 )[x -0]
⇒ y = (144/3)x

The sine and cosine of the angle of point P are sin θ = 143/145 and cos θ = -24/145 respectively. Option b. is the answer
How to determine the sine and cosine of the angle of point P?Given the coordinate of the point as P (-24/145, 143/145)
This implies x = -24/145 and y = 143/145
To determine the sine and cosine of the angle of point P, we can make a sketch using this information (see attached image).
opposite = 143/145, adjacent = -24/145
hypotenuse = √[(-24/145)² + (143/145)²] = √1 = 1
Using trigometric ratios:
sin θ = (143/145) / 1 = 143/145 [sin θ = opposite/ hypotenuse]
cos θ = (-24/145) / 1 = -24/145 [cos θ = adjacent/ hypotenuse]

Thomas earned $46.50 in 4 hours at his job today. How much can he earn tomorrow if he works 10 hours at the same hourly rate? Do NOT include a dollar sign in your answer.
Answer:
116.25 0r 116.30
Step-by-step explanation:
To find the hourly rate, divide the pay by the number of hours
So 46.50/4 = 11.625
You should round that to 11.63
Then, multiply the hourly rate by the number of hours worked the next day.
So 11.63 x 10 = 116.30
A metallurgist has one alloy containing 28% aluminum and another containing 59% aluminum. How many pounds of each alloy must he use to make 42 pounds of a third alloy containing 30%
The number of pounds from one alloy is 2.71.
The number of pounds from another alloy is 39.29.
What is an equation?An equation is a mathematical statement of two expressions connected by an equal sign.
We have,
x = pounds from one alloy
y = pounds from the second alloy
Two equation.
28% of x + 59% of y = 30% of 42
0.28x + 0.59y = 0.30 x 42 ______(1)
x + y = 42 _____(2)
Now,
x = 42 - y ________ (3)
Putting (3) in (2)
0.28(42 - y) + 0.59y = 0.30 x 42
11.76 - 0.28y + 0.59y = 12.6
11.76 + 0.31y = 12.6
0.31y = 12.6 - 11.76
0.31y = 0.84
y = 2.71
Now,
x = 42 - y
x = 42 - 2.71
x = 39.29
Thus,
The number of pounds of each alloy is 2.71 and 39.29.

What are Parallel Lines ?
Coplanar, parallel lines that don't cross at any point are called parallel lines. Planes in the same three-dimensional space that never cross each other are said to be parallel.
Since the required line is parallel to the line that passes through (4,9) and (-3,6).
So, The slope will be equal to :
m = (y^2 - y^1) / (x^2 - x^1)
here, x^1 = 4, y^1 = 9, x^2 = -3 and y^2 = 6
∴ m = (6 - 9) / (-3 - 4)
= -3/-7
= 3/7.
We know that, The equation of a line is (y - y^1) = m (x - x^1)
∴ The equation of the required line will be :
y - 9 = 3/7 ( x - 4)
