Mildred bought 2-cent stamps, 4-cent stamps, and 5-cent stamps for $4.35. The number of 2-cent stamps exceeded the number of 5 c

vfiekz [6]

5 cent = 0.05x

2 cent = 0.02(x+50)

4 cent = 0.04(2x-10)

0.05x + 0.02(x+50) + 0.04(2x-10)

0.05x + 0.02x +1 + 0.08x -0.4 = 4.35

0.15x +0.6 = 4.35

0.15x = 3.75

X = 3.75 / 0.15 = 25

25 5 cent stamps ( 25*0.05 = 1.25)

25+50 = 75 2 cent stamps ( 75*0.02 = 1.50)

2*25 =50-10 = 40 4 cent stamps ( 40*0.04 =1.60)

1.25 + 1.50 +1.60 = 4.35

5 cent = 25

2 cent = 75

4 cent = 40

What is the standard equation of the circle with radius 5 and the center (-3, -4)?

antoniya [11.8K]

Answer:

(x+3)² + (y+4)²=25

Step-by-step explanation:

The question is on equation of a circle

The distance formula is given by;

√(x-h)²+ (y-k)²=r

The standard equation of circle is given as ;

(x-h)²+ (y-k)²=r²

The equation of this circle with center (-3, -4) and radius 5 will be;

(x--3)² + (y--4)²=5²

(x+3)² + (y+4)²=25

A pair of equations is shown below:

Oksi-84 [34.3K]

If you graph y=7x-9 and y=3x-1 the two lines will intersect at one point. That is how you graphically "solve" the system of equations.

Both of these lines are of the form y=mx+b where m is the slope and b is the y-intercept.

So for y=7x-9, the slope is 7 and the y-intercept is -9

For y=3x-1, the slope is 3 and the y-intercept is -1

....

The solution for this system occurs when both coordinates are equal to each other so we can say:

7x-9=3x-1 subtract 3x from both sides

4x-9=-1 add 9 to both sides

4x=8 divide both sides by 4

x=2, making y=3x-1 become:

y=3(2)-1=6-1=5, so the solution to the system of equations is:
