The value of X is represented with a point 4 unit to the left of 0
The x coordinate will be -4 for the expression "a point 4 unit to the left of 0".
We are given an expression:
" a point 4 unit to the left of 0 "
We need to find the value of x coordinate for this expression.
In geometry, a coordinate system is a system that makes use of one or extra numbers, or coordinates, to uniquely decide the placement of the factors or different geometric factors on a manifold which include Euclidean space.
We can write the expression as:
4 unit to the left of 0 will be - 4
So the point becomes:
( - 4 , 0)
So, the x coordinate becomes,
x = - 4
Therefore, the x coordinate will be -4 for the expression "a point 4 unit to the left of 0".

A company has learned that by pricing a newly released toy at $7, sales will reach 1500 per day. Raising the price to $9 will cause the sales to fall to 1000 per day. Assume that the
ratio of change in price to change in daily sales is constant and let x be the price of the toy and y be the number of sales
a. Find the linear equation that models the price-sales relationship for this toy. (Hint: The line must pass through (7,1500) and (9,1000)]
b. Use this equation to predict the daily sales of the toy if the price is set at $8.50
a. Find the linear equation that models the price-sales relationship for this toy
(Simplify your answer)
b. Predict the daily sales of the toy if the price is set at $8.50.

(a) The linear equation that models the price-sales relationship for this toy is y = -250 x + 3250 .
(b) The daily sales of the toy if the price is set at $8.50 will be $1125
Slope for two points is given by m = y₂ -y₁ / x₂ - x₁ where ( x₁, y₁) are the coordinate of first point and (x₂, y₂) are the coordinate of second point.The most common variety of linear equations is in slope-intercept kind, that is pictured as y = mx + b where, m is that the slope of the road, b is that the y-intercept , x and y are the coordinates .An equation may be a statement, that has AN equal sign (=) between the pure mathematics expression. Linear equations are the equations of degree one.
(a) Let "x " be the price of the toy and "y" be the number of sales.
Then equation is given by y = mx + c .......(1)
It is given that ($7, 1500 sales/day) and ($9,1000 sales/day).
Using slope formula , for these two points , we get
m = 1000 - 1500 / 9 -7
= -500 / 2
= -250
Putting x = 7 and y = 1500 and m = -250 in equation (1) , we get
1500 = (-250)(7) + c
1500 = - 1750 +c
c = 3250
Putting c = 3250 and m = -250 in equation (1) , we get
y = -250 x + 3250 ........(2)
(b) Put x = 8.50 in equation (2) , we get
y = -250(8.50) + 3250
= -2125 + 3250
= $ 1125

Sutton's cellphone plan calculates her bill by using the function, b (z) = 0.05x+75, where x is the number of minutes she uses the phone. What is her bill if she uses her
phone for 10000 minutes?
If she uses its phone for 10000 minutes, her cost will be $575.
What is linear equation:The typical form for two-variable linear equations is Ax+By=C. For example, 2x+3y=5 is a common linear equation. It is rather simple to find both intercepts when an equation is stated in this way (x and y).
According to the given data:The function b (z) = 0.05x+75,
value of x = 10000 minutes
Now putting the value of x into the equation we get:
b (z) = 0.05x+75,
b (z) = 0.05(10000)+75,
b (z) = 0.05(10000)+75,
= 500 + 75
b (z) = 575
The bill if she uses her phone for 10000 minutes = 575.

The Chen family and the Aoki family each used their sprinklers last summer. The water output rate for the Chen family's sprinkler was 40L per hour. The water output rate for the Aoki family's sprinkler was 25L per hour. The families used their sprinklers for a combined total of 65 hours, resulting in a total water output of 2000L. How long was each sprinkler used?
Answer:
Chen family used the sprinklers for 25 hours
Aoki family used the sprinklers for 40 hours
Step-by-step explanation:
Let C be the number of hours the Chen family used the sprinklers and let A be the number of hours the Aoki family used the sprinklers
Total hours used
=> C + A = 65 (1)
Total water usage for Chen family = 40C (40 L per hour x no. hour)
Total water usage for Aoki family = 25C (25 L per hour x no. hours)
Total used by both families = 2000 L
So
40C + 25A = 2000 (2)
Therefore we have two equations in 2 variables which can be solved simultaneously
Multiply (1) by 25:
==> 25C + 25A = 25 x 65
==> 25C + 25A = 1,625 (3)
Subtract (3) from (2) to eliminate the A term:
(2) - (3) ==>
40C + 25A - (25C + 25A ) = 2000 - 1625
40C + 25A - 25C - 25A = 375
40C - 25C = 375
15C = 375
C = 375/15
C = 25
So the Chen family used the sprinklers for 25 hours
Since C + A = 65
A = 65 - C
==> A = 65 - 25
A = 40
The Aoki family used the sprinklers for 40 hours

a. Write a recursive definition for this sequence using function notatio
b. Sketch a graph of the first 5 terms of a
We get the function notation as aₙ = 15 - 4 n for the arithmetic sequence beginning with 11, 7,...
We are given an arithmetic sequence:
11, 7, …
We get from the sequence that:
a = 11 ( initial term )
d = 7 - 11 = - 4 ( common difference )
Now the nth term will be given as:
aₙ = a + (n - 1) d
aₙ = 11 + (n - 1) ( - 4 )
aₙ = 11 - 4 n + 4
aₙ = 15 - 4 n
Third term = 7 - 4 = 3
Fourth term = 3 - 4 = - 1
Fifth term = - 1 - 4 = - 5
Therefore, we get the function notation as aₙ = 15 - 4 n for the arithmetic sequence beginning with 11, 7,...

b = 5
A = h(B+b)
Now,
A = h(B+b)
Putting the given values,
39 = h(8+5)
or, 39 = h×13

HELLPPPP!!!!!! If the parent function f(x) = |x| is transformed to h(x) = |x| + 2, what transformation occurs from f(x) to h(x)? How are the vertex and range of h(x) affected?
h(x) is a translation upwards of 2 units of f(x), and the new range of the function h(x) will be [2, ∞)
What transformation is applied to f(x)?
We know that f(x) is the parent absolute value function:
f(x) = |x|
It is transformed so we get:
h(x)= |x| + 2
Remember that a vertical translation of N units is written as:
h(x) = f(x) + N
if N > 0, the translation is upwards.if N < 0, the translation is downwards.Then h(x) is a translation upwards of 2 units of f(x), and the new range of the function h(x) will be [2, ∞)
