 3(4h+3d=18.25)-2(6h+4d=26.50)

12h+9d-12h-8d=54.75-53

d=1.75, use either original equation to solve for h...

4h+3(1.75)=18.25

4h+5.25=18.25

4h=13

h=3.25

So the cost of one hamburger and one drink is:

3.25+1.75=$5.00

H=hamburgers.
D=drinks

3(4h+3d=18.25) - 2(6h+4d=26.50)

12h+9d-12h-8d=54.75-53

d=1.75

4h+3(1.75)=18.25

4h+5.25=18.25

4h=13

h=3.25

cost of one hamburger and one drink is:

3.25+1.75=$5.00

The radius of the circle whose equation is (x-3)^2 + (y+1)^2 = 16 is
Firdavs [7]

Answer:

4

Step-by-step explanation:

The general equation of a circle with center (a, b) and radius r is given by the equation;

(x-a)^{2}+(y-b)^{2}=r^{2}

The constant in the right hand side of the equation is simply the square of the radius;

We have been given the following equation;

(x-3)^2 + (y+1)^2 = 16

Comparing this with the general equation above;

r^{2}=16\\\\r=\sqrt{16}=4

Triangle STU is rotated 270 clockwise about the origin to create triangle S'T'U'. If point U of triangle STU is a (a,b), which a
nadya68 [22]

Answer:

(b, -a)

Step-by-step explanation:

First note that the rule for a rotation by 270° about the origin is (x,y)→(y,−x)

Note that the coordinates were swapped and the x coordinates negated. Similarly;

Given the coordinate of the point U as (a, b), if the triangle is rotated 270degrees clockwise, the resulting coordinate will  be (b, -a)
