passes through (-2,-2) and is parallel to the line 5x-y=45x
The equation of the line is y + 40x = -78.
Here, we are given that a line passes through point (-2,-2) and is parallel to the line 5x - y = 45x.
when two lines are parallel their slopes are equal. So, let us first find the slope of line 5x - y = 45x.
The standard form of the equation of a line is- y = mx + c, where m is the slope of the line.
Here 5x - y = 45x can be written as-
y = -40x
Thus, the slope of the line is -40.
Now we can use the point slope form to find the equation of our line.
According to the point slope form-
(y - y1) = m(x - x1)
here, x1 = -2 and y1 = -2
Thus equation becomes-
(y + 2) = -40 ( x + 2)
y + 2 = -40x - 80
y + 40x = -78
Thus, the equation of the line is y + 40x = -78

Step-by-step explanation:
The airfare from peshawar to karachi of an airline is rupees 5700 .what will be the selling price of this ticket if rupees 1500 airport tax and gst at the rate of 16.5% are included.
The selling price of the ticket is rupees 8140.5 if a person travelling from Peshawar to Karachi.
What GST means?
GST is a single tax on the supply of goods and services, right from the manufacturer to the consumer
The airfare from peshawar to karachi of an airline is rupees 5700 .
what will be the selling price of this ticket if rupees 1500 airport tax
and GST at the rate of 16.5% are included.
since GST is calculated on 5700 at the rate of 16.5%
then 5700 * ( 16.5)/100
= 57 * 16.5
= 940.5
then selling price of ticket is sum of all the value
that is 5700 + 1500 + 940.5 = 8140.5
Hence , the selling price of the ticket is rupees 8140.5 if a person travelling from Peshawar to Karachi.

In the morning Josh completed a hike on a 5/14 mile trail. In the afternoon he completed a hike on a second trail using his pedometer to keep track of the miles. The pedometer measured 3.35 miles for the second trail. What is the total number of miles Josh hiked? Enter your answer as a decimal to the nearest tenth.
Answer:
Total distance travel = 8.60 miles
Step-by-step explanation:
Given:
Distance of 1st trail = [tex]5\frac{1}{4}[/tex] miles = 5.25 miles
Distance of 2nd trail = 3.35 miles
Find:
Total distance travel
Computation:
Total distance travel = Distance of 1st trail + Distance of 2nd trail
Total distance travel = 5.25 + 3.35
Total distance travel = 8.60 miles
the vertices of an isosceles triangle are a(-10, 1), b(-6, 3) and c(-4, 7). what is the equation of the triangle's line of symmetry?
The equation of the triangle's line of symmetry is Y= X+10.
Equation: The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.
Symmetry: Symmetry means that one shape is identical to the other shape when it is moved, rotated, or flipped. If an object does not have symmetry, we say that the object is asymmetrical. The concept of symmetry is commonly found in geometry.
Isosceles triangle is a triangle that has at least two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case.
It is given that an isosceles triangle with sides A(-10,1) ; B (-6,3) ; C(-4,7) is drawn and we notice that, the mid point of AB is the perpendicular bisector of the line AB.
Mid point of AB = (-8,2)
Slope of AB = [(-10) - (-6)] / (1 - 3)
=> -4 / -2
=> 2
Slope of perpendicular bisector of AB = 1
Equation of the line of symmetry = (Y - 2) = 1 [X - (-8)]
=> Y - 2 = X + 8
=> Y= X+10
Therefore, the equation of the triangle's line of symmetry is Y= X+10.

Marisha wants to measure the volume of a rock. She pours water into a graduated cylinder and it measures 200 mL. Then she drops the rock in it, and measures the water level at 297.5 mL. The volume of the rock is the difference between the water level before and after. What is the volume of the rock
Answer:Volume of Rock= 97.5ml
Step-by-step explanation:
STEP 1
Finding the volume of rock using the graduated cylinder that measures volume of liquid can be done by determining how much water is being displaced by the rock after submersion.
Step 2
Volume of water before adding rock = 200mL
Volume of water after adding the rock = 297.5mL
Volume of rock =Volume of water after adding the rock - Volume of water before adding rock
Volume of Rock = 297.5-ml 200ml
= 97.5ml

a marathon swim follows a triangular course marked with three buoys, a, b, and c. the distance from buoy a to b is 400 meters, b to c is 500 meters, and c to a is 600 meters. what is the largest angle the swimmers must turn between the buoys? 97.181° 82.819° 55.771° 41.410°
The largest angle the swimmers must turn between the buoys is 82.8°. Therefore, option B is the correct answer.
Given the following data:
Side AB = c = 400 meters.
Side BC = a = 500 meters.
Side CA = b = 600 meters.
How do determine the largest angle?In order to determine the largest angle at which the swimmers must turn between the buoys, we would apply the law of cosine.
Form the law of cosine, for angle C we have:
cos C= (a²+b²-c²)/2ab
=(500²+600²-400²)/2×500×600
=450000/600000
cos C=0.75
⇒C=41.4°
For angle B we have:
cos B= (a²+c²-b²)/2ac
=(500²+400²-600²)/2×500×400
=1/8
cos B=0.125
⇒B=82.8°
For angle A, we have:
cos A= (b²+c²-a²)/2ac
=(600²+400²-500²)/2×600×400
=9/16
cos A=0.5625
⇒A=55.8°.
The largest angle the swimmers must turn between the buoys is 82.8°. Therefore, option B is the correct answer.

Given m
11
n, find the value of x and y.
(9x+1)
m
jo
(7x+13)
n
Answer:
x = 6
y° = 125°
Step-by-step explanation:
9x + 1 and 7x + 13 are alternate angles and has same measurement
9x + 1 = 7x + 13
9x - 7x = 13 - 1
2x = 12
x = 6
y° and 7x + 13 are supplementary angles so their sum is 180°
7x + 13 ➡ 7×6 + 13 = 55°
55 + y° = 180 subtract 55 from both sides
y° = 125°

If John deposits $525 in a savings account and his account pays an annual interest rate of 5.5% and makes no other deposits and withdrawals what is the simple interest earned for 5 years , 5 months , and 5 days
Answer:
The amount of simple interest earned is $156.79
Step-by-step explanation:
Mathematically;
Simple interest = PRT/100
From the question;
P = $525
R = 5.5%
T ; to get this, we need to make the numbers agree;
We do this by dividing number of months by 12 and number of days by 365
So 5 years, 5 months and 5 days will be;
5 + 5/12 + 5/365 = 5.43
So, using this in the simple interest calculations, we have;
S.I = (525 * 5.5 * 5.43)/100
S.I = $156.79
