Answer:
The x-intercept is (2, 0)
Step-by-step explanation:
To find the x intercept we simply replace the y with 0 and solve for x.
5x=10
we divide both sides by 5 and get that
x=2.
Answer:
The y intercept is (0, 8). The equation of the function is f(x) = 10x + 8
Step-by-step explanation:
Given that after 1 hour of work, Jack will make 18 dollars and the slope is 10, subtract 10 dollars from 18 dollars to find his set amount, or y-intercept.
18 - 10 = 8 dollars.
Now that we have the m and b values, we can create our equation.
The equation in standard form is f(x) = mx +b, where m = the slope and b = the y-intercept. Plug our values in and the equation will be f(x) = 10x + 8. You can test if this is correct by plugging in x values from the table and seeing if your calculated value correctly corresponds to the given y value in the table.
Answer:
243
Step-by-step explanation:
-5(1-4)^2+18
(-5+20)^2+18
225+18
=243
COPYING IS NOT AT ALL GOOD MY BOY ! TRY TO CHANGE THAT HABIT
Answer:
Costs are $490
49 shirts are sold
98 + 8x = 10x
98 = 2x
49 = x
98 + 8(49) = $490 in costs
49 shirts sold
Step-by-step explanation:
98 + 8x = 10x
98 = 2x
49 = x
98 + 8(49) = $490 in costs
49 shirts sold
