Answer:
y-6 = -1/2 * (x-1)
Step-by-step explanation:
Point slope form is y - y1 = m(x - x1), where (x1, y1) is the point and m is the slope. Plug in (1,6) for (x1, y1) and -1/2 for m.

Which table shows y as a function of x
Identify the x-intercept and y-intercept
Answer:
x: -6, y: -2
Step-by-step explanation:
look at the graph, I hope this is the x and y of the lines. It says the answers, but just identify it.
Answer:
(- 6, 0 ) and (0, - 2 )
Step-by-step explanation:
The x- intercept is the value of x on the x- axis where the line crosses.
Here x = - 6 ← x- intercept or (- 6, 0) in coordinate form
The y- intercept is the value of y on the y- axis where the line crosses.
Here y = - 2 ← y- intercept or (0, - 2 ) in coordinate form

Games-R-Us offers a video game rental program with a monthly fee of $10 plus $2 per game rental. Games2Go charges a $2 monthly fee plus $4 per game. Given the same to stores Games-R-Us and Games2Go, how many games would you have to rent from each company to have your total cost be the same amount?
Answer:
4 games
Step-by-step explanation:
Let the number of games rented from both be represented by: g
For Games - R - Us
Games-R-Us offers a video game rental program with a monthly fee of $10 plus $2 per game rental.
$10 + $2 × g
= 10 + 2g
For Games2Go
Games2Go charges a $2 monthly fee plus $4 per game.
$2 + $4 × g
= 2 + 4g
Hence,
Games-R-Us = Games2Go
10 + 2g = 2 + 4g
Collect like terms
10 - 2 = 4g - 2g
8 = 2g
g = 8/2
g = 4 games
Therefore, number of games you would have to rent from each company to have your total cost be the same amount is 4 games

The math teacher gives each student a map of the amusement park that uses a coordinate plane. The meeting location is at (0, 0) on the map. Each unit is 100 feet. The first ride that you want to try is located at the coordinates (0, 4). The next ride is located at (3, 0). If you walked in a straight line from the first ride to the second ride, how many feet would you travel?
Answer:
500 ft
Step-by-step explanation:
use this formula
The actual distance between first and second ride is 500 ft.
What is Distance Formula?The distance between two point P(a, b) and Q(c, d).
so, the distance PQ = √(c-a)² + (d- b)²
Given:
Starting point = (0,0)
First ride = (0,4)
Second ride = (3,0)
In map, each unit = 100 ft
Using the distance formula
d = √( 3-0)² + (0-4)²
d = √9+ 16
d= √25
d = 5 units
So, the distance between first ride and second ride in the map is 5 units.
and,1 units = 100 ft
5 units = 500 ft
Hence, the actual distance between first and second ride is 500 ft.

A phone shop sells iPhones and Samsung phones in a ratio of 7:5.
Last week the shop sold 42 iPhones.
How many Samsung phones did it sell?
Answer:
30
Step-by-step explanation:
Given the ratio 7 : 5
The 42 iPhones sold relates to the 7 part of the ratio.
Divide 42 by 7 to find the value of one part of the ratio.
42 ÷ 7 = 6 ← value of 1 part of the ratio, thus
5 parts = 5 × 6 = 30 ← number of Samsung phones sold

Please help asap
Answer:
f(4) for the function [tex]f(x) = 7x + 6[/tex] is [tex]\mathbf{f(4)=34}[/tex]
Step-by-step explanation:
We need to find f(4) for the function [tex]f(x) = 7x + 6[/tex]
For finding f(4) we will put x= 4 in the given function
[tex]f(x) = 7x + 6[/tex]
Put x = 4
[tex]f(4)=7(4)+6\\f(4)=28+6\\f(4)=34[/tex]
SO, f(4) for the function [tex]f(x) = 7x + 6[/tex] is [tex]\mathbf{f(4)=34}[/tex]
The diagram below shows part of the graph of the equation y= the graph intersects the x-axis at the points. Find the value of a and the value of b. I'm not allowed to use the calculator and I need the process
The value of a and b are 11 and 14.
What is an equation on a graph?The equation on a graph shows the point where the equation intersects
on the x-axis and the y-axis.
We have,
The function as y = 2x² + ax + b
Where it intersects on the x-axis at the points (-7/2, 0) and (2, 0).
Now we can write it as:
At point (-7/2, 0).
0 = 2 (-7/2)² + a(-7/2) + b
0 = 49 / 2 - 7a/2 + b
7a/2 - b = 49/2 _____(1)
At point (2, 0)
0 = 2(2)² + 2a + b
0 = 8 + 2a + b
2a + b = -8 _____(2)
From (1) and (2) we can find a and b.
From (1)
7a/2 - 49/2 = b
b = (7a - 49) / 2 ______(3)
putting in (2)
2a + (7a - 49) / 2 = -8
4a + 7a - 49 = -16
3a - 49 = -16
3a = -16 + 49
3a = 33
a = 11
putting in (3)
b = (7x11 - 49) / 2
b = (77 - 49) / 2
b = 28 / 2 = 14
Thus the value of a and b are 11 and 14.

The value of a and b for the given equation is 3 and -14 respectively.
The given equation is y=2x²+ax+b, (-7/2, 0) and (2, 0).
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Now put (-7/2, 0) and (2, 0) in the given equation and find a and b value.
That is, 0=2 (-7/2)²+a(-7/2)+b
⇒ 49/2 -7a/2+b=0 ----(I)
0=2(2)²+a(2)+b
⇒ 8+2a+b=0
⇒ b=-2a-8 -----(II)
Put b=-2a-8 in equation (I) and simplify.
That is, 49/2 - 7a/2 -2a-8=0
⇒ 49/2 - 11a/2 - 8 =0
⇒ 49 - 11a=16
⇒ 11a=33
⇒ a=3
Put a=3 in equation (II) and simplify.
That is, b=-2(3)-8=-14
Therefore, the value of a and b for the given equation is 3 and -14 respectively.

The required function is: 576,001 - ( 0.11 * 576,001 * x )
The value of the helicopter after 12 years, to nearest dollar is -$184320
How to find the value of the helicopter after 12 yearsGiven data
price of a helicopter $576,001
rate of value decrease is 11%
The decrease in value will result to
= 576,001 - 0.11 * 576,001 * x
let x represent the number of years
the required function is: 576,001 - 0.11 * 576,001 * x
plugging in 12 and solving results to
= 576,001 - 0.11 * 576,001 * x

Ani sells 527 dollars worth of sodas as part of a school club fundraiser. If the sodas cost 310 dollars, what equation can we make to find out how much money ani raised as the variable ?
The total money Ani raised was 217 dollars.
Cost price of soda = 310 dollars
money raised = selling price - cost price
What is selling price?
The cost at which something is sold. Calculate the total cost of all the items you bought. To calculate the cost price, divide the total cost by the quantity of units purchased. Use the selling price formula to calculate the final price: Cost price plus profit margin equals selling price.
What is cost price ?
Cost price is the complete sum of money that a manufacturer must spend to create a specific good or render a specific service. Cost is equal to Selling price plus Loss ( when selling price and loss is given ) Cost price = 100 Selling Price + 100 + Profit (where the Selling Price and Profit Percentage are supplied)
Hence
x = 527 - 310
