lets say that y is biggerr
y-x=5
and
y=x+5

pproduct is 126
xy=126
substiutute x+5 for y
(x+5)(x)=126
x^2+5x=126
x^2+5x-126=0
factor
whaat 2 numbbers multtiply to get -126 aand addd to gget 5
-9 and 14
(x-9)(x+14)=0
sset to zzero
x-9=0
x=9, nah we nneed 2 nnegative nnumbers

x+14=0
x=-14

so thenn
y=x+5
y=-14+5
y=-9

the summ is -14-9=-23

If b>a, b-a=5 so b=5+a

ab=126, using b from above

a(5+a)=126

5a+a^2=126

a^2+5a-126=0
 
(a+14)(a-9)=0, since a<0 the numbers are

-14 and -9

Consider the parabola with a focus at the point (4,0) and directrix y = 3.
satela [25.4K]

Answer:

answer of your questions

Step-by-step explanation:

The process of obtaining the equation is similar, but it is more algebraically intensive. Given the focus (h,k) and the directrix y=mx+b, the equation for a parabola is (y - mx - b)^2 / (m^2 +1) = (x - h)^2 + (y - k)^2.

I won $60,000 I invested part in a CD at 2% interest the rest at 3%interest in a cd at the end of the year I earned $1600 in int
zaharov [31]
Let x = amount invested in 2% CD and y = amount invested in 3% CD
x + y = 60000
0.02x + 0.03y = 1600
SOLVE THE 1st EQUATION FOR x AND SUBSTITUTE RESULT IN 2nd
0.02(60000 - y) + 0.03y = 1600  
1200 - 0.02y + 0.03y = 1600
0.03y = 400
y = 13333.34
x = 46666.66

The length of a rectangle is 3 meters more then the width the perimeter of ractangle is 26 meters
Fudgin [204]

Answer:

Step-by-step explanation:

Let's say the width is x. If the length is 3 meters more than the width, the the length is x+3.

A rectangle has 4 sides. 2 widths and 2 lengths. If the perimeter is 26 meters, you can plug in your expressions for the width and the length to solve for x.

2(x+3) +2(x)=26

2x+6+2x=26

4x+6=26

4x=20

x=5.

If x=5, that means that your with is 5 meters, and your length is 8 meters (5+3)
