Which equation best represents the relationship between x and y in the graph
Answers
The equation of the line is y= 3 - 2x.
What is equation?An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra.
Given:
Coordinates (0, 3) and (2, -1)
So,
slope = -4/2=-2
and equation of line is
(y- y1) = m (x- x1)
y-3 = (-2)(x-0)
y-3 = -2x
y= 3 - 2x
Hence, the equation of line is y= 3 - 2x.

Explanation: We can model this with an equation where your balance must be at least 250. "At least" means greater than or equal to, so the account balance must be greater than or equal to 250. The balance is your starting amount minus any purchases and plus any deposits, so:
286.14 - 123.88 + x >= 250
Where x is what you need to deposit
This simplifies to

Find 6y + 10z - 2yz, use y=2 and z=3
Answers
Answer:
30
Step-by-step explanation:
6(2) + 10(3) - 2(2)(3)
12 + 30 - 2(6)
42 - 12
30
The value of the expression 6y + 10z - 2yz when y = 2 and z = 3 is 30.
What is the value of the expression when y=2 and z=3?Given the expression in the question:
6y + 10z - 2yz
y = 2
z = 3
To determine the value of the expression 6y + 10z - 2yz, we simply substitute y = 2 and z = 3 into the expression and then simplify.
6y + 10z - 2yz
Plug in y = 2:
6( 2 ) + 10z - 2(2)z
Plug in z = 3:
6( 2 ) + 10( 3 ) - 2(2)(3)
Simplifying, we get:
12 + 30 - 12
Add 12 and 30:
42 - 12
Subtract 12 from 42:
30
Therefore, the value of the expression is 30.

Find the inverse of each function.
y=log₂4 x
Answers
The inverse function of the function y = log₂ 4x is f ⁻¹(x) = 2ˣ/4.
Given the function is :
y = log₂4x
we are asked to find the inverse of the function.
steps to find inverse function are:
Change f(x) to y to get y = ax + b for the provided function f(x) = ax + b.To get x = ay + b from the equation y = ax + b, replace x with y and y with x.Here, find y and solve for x = ay + b. Then we get y = (x - b/a).Finally, we can substitute y = f-1(x) with f-1(x) = (x - b)/a.now interchange the positions of x and y in the function.
x = log₂4y
the next step is to isolate the dependent variables.
f ⁻¹(x) = 2ˣ/4
hence, we get the inverse of the given function as f ⁻¹(x) = 2ˣ/4

(F) x²-3 x-3 (G) x²-x-6 (H) x²-x (I) x²-x-3
Answers
The value of the composite function f o g (x) is x² - 3 x - 3.
We have the functions:
f (x) = x + 1 and g (x) = x² - 3 x - 4
We need to find the composite function:
f o g (x)
= f ( g (x) )
Substituting the values, we get that:
= ( x² - 3 x - 4 ) + 1
= x² - 3 x - 4 + 1
= x² - 3 x - 3
Therefore, the value of the composite function f o g (x) is x² - 3 x - 3.

A point on the edge of a symmetrical canyon is 4500 feet above a river that cuts through the canyon floor. The angle of depression from each side of the canyon to the canyon floor is 60o.
a) Find the length of the canyon wall (from the edge to the river).
feet
b) Find the distance across the canyon.
feet
c) Is it more or less than a mile across the canyon? (5280 feet = 1 mile) more or less
Answers
The length and distance across the canyon is 5196.15 feet and it is more than 1 mile.
a) To find the length of canyon, we will sine function. As per the sine theta = length of opposite side ÷ hypotenuse. Keep the values in formula to find the hypotenuse, which is the length of the canyon wall.
sin 60 = 4500 ÷ hypotenuse
Hypotenuse = 4500 ÷ (✓3/2)
Hypotenuse = 4500 × 2 ÷ ✓3
Hypotenuse = 9000 ÷ ✓3
Hypotenuse = 5196.15 feet
The length of the canyon wall is 5196.15 feet.
b) To find the distance across the canyon, we will use cosine function. As per the cos theta = base ÷ hypotenuse. Keep the values in formula to find the base, which is half the length of the distance across the canyon.
cos 60 = base ÷ 5196.15
cos 60 × 5196.15 = base
Base = (1/2) × 5196.15
Base = 2958.075 feet
Total distance across the canyon = 2958.075 + 2958.075
Tota distance across the canyon = 5196.15 feet
c) Using the relation, 5280 feet = 1 mile
5196.15 feet = 5196.15 ÷ 5280 mile
5196.15 feet = 1.12 miles
So, distance across the canyon is more than 1 mile.

C.55,000 ft per second
D.1,188,000 ft per second
Answers
The speed with which the airplane is flying in feet per second is 917 ft per second.
The speed at which an object's location changes in any direction. The distance travelled in relation to the time it took to travel that distance is how speed is defined. Given that it just has a direction and no magnitude, speed is a scalar number.
It is given that,
The speed with which the airplane is flying is = 625 mile per hour
We need to find the speed of the airplane in feet per second
Number of seconds in 1 hour = 60 x 60 = 3600s
Number of feet in 1 mile = 5280 feet
Number of feet in 625 mile = 5280 x 625 = 33,00,000 feet
Speed of airplane in feet per second = [tex]\frac{33,00,000}{3,600}[/tex]
= 916.66 feet per second
~917 feet per second
Hence, the speed with which the airplane is flying in feet per second is 917 ft per second.

Answers
Justin borrow $6,000 from a credit union for 2 years.
What is Principal amount?
The amount of money initially borrowed from the lender, and as the loan is repaid, it can also refer to the amount of money still owed, is called Principal amount.
Given that;
Simple interest = $840
Time = 2 years
Annual rate = 7%
Now, The formula for calculate the principal amount is,
Simple interest = Principal amount × Rate × time / 100
Principal amount = Simple interest × 100 / Rate × time
Hence,
Principal amount = 840 × 100 / 7 × 2
Principal amount = 84,000 / 14
Principal amount = $6000

Given that ,
Equation represents Michelle’s regular hourly and overtime wage
= 130 (x – 38) + 950% > 38
We have to find Michelle’s overtime hourly payment.
Let’s solve the above given equation:
130 (x – 38) + 950% x 38 = 0
130x – 4940 + (950/100) x 38 = 0
130x – 4940 + 9.5 x 38 = 0
130x – 4940 + 361 = 0
130x – 4579 = 0
130x = 4579
X = 4579 / 130

Answers
The bird settles on the branch at the rate of 2.33 meters per second.
What is the rate of change?The rate of change refers to the traveling speed of the bird when perching on the branch.
The rate of change (which is speed) is the distance (altitude) divided by time.
Data and Calculations:The bird's flying altitude above ground = 10 meters
Time in seconds to settle on a branch = 3 seconds
The altitude above ground after settling on the branch = 3 meters
The change in altitude = 7 meters (10 - 3)
Rate of change = 2.33 meters per second (7/3)
