Answer:
-2
Step-by-step explanation:
Just walk your finger from left to right until you get to x=0 (the numbers on the horizontal axis). when you get there, find the y value (find how much you need to go up or down to get to where the function goes)
Hello,
Let's put the 6 houses on side: 6P9=9*8*7*6*5*4/6! = 84
For each choice there are 3! choices pour the other side
84*3!=504
Given:
The cost of each carnival ticket is $5.
To find:
The equation, table of values and graph for the given problem.
Solution:
Let x be the number of tickets and y be the total money spent on tickets.
Cost of one ticket = $5
Cost of x tickets = $5x
So, total cost is
The required equation is .
At x=1,
At x=2,
At x=3,
The required table of values is
x y
1 5
2 10
3 15
So, the required table of values is table A.
From the above table, it is clear that the graph passes through the point (1,5), (2,10) and (3,15). The graph B passes through these points.
So, the required graph is graph B.
Since the required answers are , table A, graph B, therefore the correct option is B.
Answer:
-7
Step-by-step explanation:
Square numbers always have two possible roots: a positive and negative root. This is because two positive numbers multiply to make a positive number and two negative numbers also multiply to make a positive number
-7 × -7 is still 49, just like 7 × 7
Hope this helps!

Answer: -4x+5y = 100</h3>
===================================================
Explanation:
The given equation is the same as -4x+5y = 10
It is of the form Ax+By = C, where A = -4, B = 5, C = 10
Anything parallel to Ax+By = C is of the form Ax+By = D. The only difference is the C has changed to a D.
This means anything parallel to -4x+5y = 10 is -4x+5y = D, where D is not equal to 10, but it could be any other number.
Plug in the coordinates of (-15,8) to find the value of D
-4x+5y = D
-4(-15)+5(8) = D
60+40 = D
100 = D
D = 100
We have -4x+5y = D update to -4x+5y = 100
The equation -4x+5y = 100 is parallel to -4x+5y = 10, and it goes through (-15,8)
Parallel lines have the same slope, but different y intercepts.
Note how Ax+By = C has a slope of m = -B/A. This means A cannot be zero.
