Answer:
equation: y=-4x-7
Step-by-step explanation:
y=-4x+b
solve for b using given coordinates on the line (-3, 5)
5=-4(-3)+b
b=-7
1. An expression that will represent the amount of money that Ms. Thomas will spend is <u>p + 45n - c.</u>
2. The amount of money that Ms. Thomas will spend on the comedy tickets for herself and her 2 friends is <u>$155</u>.
<h3>What is a mathematical expression?</h3>
A mathematical expression is a statement that involves two or more variables that require some mathematical operations.
Most commonly, a mathematical expression contains numbers, variables, and operators, which show a value after the mathematical operations.
<h3>Data and Calculations:</h3>
Parking fee = $35
Ticket fee per person = $45
The number of people on the show = 3 (Ms. Thomas and her two friends)
Coupon = $15
Amount of money spent = p + 45n - c
where p = parking fee, n = number of visitors, and c = coupon received.
= 35 + 45 x 3 - 15
= $155

Answer:
Step-by-step explanation:
trapezium
<h2>If the diagonals of a quadrilateral divide each other proportionally, then prove that the quadrilateral is a trapezium.</h2>
Our first step is to figure out what formulas are needed for diameter, circumference, and area of a circle.
Diameter is simply twice the size of the radius so:
2 * radius = 2 * 40 feet = 80 ft.
Circumference = 2 * pi * radius = 80 ft * pi
If we say that pi = 3.14, then:
circumference = 251.2 ft.
Area = pi * radius^2 = pi * 1600 ft^2
Once again, if we assert pi = 3.14, then:
area = 3.14 * 1600 ft^2 = 5024 ft^2.
Answer:
x = 3/8 (but the fraction is negative.)
Decimal form if needed.
x = - 0.375
