U would replace ur -4 with the x’s so ur problem would look like <-2(-4)-10> and then solve that and u would get (2) for ur answer...
Answer:
1) The 15%-off coupon is $3.
2) The cost of the meal after the discount is $17.
3) The final cost of the meal with taxes is $18.19.
Step:
1) To find the discount, try to find the amount of 1%, (20÷100 x 15 = 3)
2) To find the cost of the meal after discount (20-3 = 17)
3) To find the final cost, try find the taxes amount (17÷100 x 7 + 17 = 18.19)
For problems like these, we use something called a
ceiling function, in which
. If we do
, we get that we do
, which is
14 buses. We take the ceiling of the division because if we don't, we know that there are going to be extra kids left over that won't be able to seat on a bus. If we just rounded down to 13 buses, we would have been able to seat only 936 kids, a full 64 kids left over.
Answer:
Step-by-step explanation:
The standard form of an equation of a circle:
(h, k) - center
r - radius
The general form of an equation of a circle:
We have the center (-2, 1). Substitute to the equation in the standard form:
Put thr coordinates of the point (-4, 1) to the equation and calculate a radius:
Therefore we have the equation:
Convert to the general form.
Use
Answer:
The answer would be B.
Step-by-step explanation:
The X-intercept is simply the point in which the line crosses the x axis, and the point where it crosses or touches is 0, 0
