So you wanna do the slope intercept form...
m = y2-y1/x2-x1 then plug vaules
14 - 10 / 9 - 6 gives you...
4/3x...
so Y= 4/3x...
now we want the values of a point (3,6) 3 being your x, 6 being your Y. so plug it in...
Y= 4/3(3) + 6
4/3 x 3 is 4 the 3 cancels plus 6 is 10...
let's check our work a bit? do we have a value of Y that equals 10? Oh (6,10) 10 is a Y value and adds with our answer.
Answer:
She must score 90 points
Step-by-step explanation:
Find the average of the first 2 tests
76 + 80 = 156
Divide the sum of the first 2 tests by how many tests there were
156 ÷ 2 = 78
Multiply 82 by 3
82 x 3 = 246
Subtract 156 from 246
246 - 156 = 90
Add all the numbers together to get the average
90 + 80 + 76 = 246
246 ÷ 3 = 82
Hope this helps!
Answer:
She will receive 64 cents in change.
Step-by-step explanation:
Cost per pound of ham = $4.99
Pounds bought = 1.5
Cost of 1.5 pounds = 4.99 * 1.5 = $7.485
Cost per pound of other item = $2.50
Pounds bought = 0.75
Cost of 0.75 pounds = 0.75 * 2.50 = $1.875
Total = 7.485 + 1.875 = $9.36
Amount paid = $10
Change received = 10 - 9.36 = $0.64
Therefore,
She will receive 64 cents in change.
You add the numbers up so 53

Answer:
y = 0.2·0.5^x
Step-by-step explanation:
An exponential function is generally of the form ...
y = a·b^x
where 'a' is the function value when x=0, and b is the ratio between values for x=1 and x=0.
In the given table, y = 0.2 for x = 0, so a = 0.2.
We find that the value for x = 1 is 0.1, so the value of b is ...
b = 0.1/0.2 = 0.5
Then the exponential function is ...
y = 0.2·0.5^x
