What two numbers have a difference of 5 and a product of 3.36

Mathematics

X-y=5
xy=3.36
add y to both sides on first
x=5+y
sub that in other eqation
(5+y)y=3.36
expand
y^2+5y=3.36
minus 3.36 both sides
y^2+5y-3.36=0
use quadratic formula


for
ay^2+by+c=0
y= \frac{-b+/- \sqrt{b^2-4ac} }{2a}
for 1y^2+5y-3.36
y= \frac{-5+/- \sqrt{5^2-4(1)(-3.36)} }{2(1)}
y= \frac{-5+/- \sqrt{25+13.44} }{2}
y= \frac{-5+/- \sqrt{38.44} }{2}
y= \frac{-5+/- 6.2}{2}
y=-2.5+/-3.1
y=5.6 or 0.6
sub back

x=y+5
so
x=10.6 or 5.6


the numbers are either 10.6 and 5.6 or 0.6 and 5.6
wait,but 10.6 and 5.6 don't multiply to get 3.36 so that is an extrainiesous answer

answer is 0.6 and 5.6

Find the y-intercept for the parabola defined by
wolverine [178]

Answer:

12

Step-by-step explanation:

Set x=0

when you do that, you will find the point where y=12 since x^2+8x=0, but adding the 12 moves up the y-component by 12 units

Consider the graph of the quadratic function y = 3x2 – 3x – 6. What are the solutions of the quadratic equation 0 = 3x2 − 3x − 6
Ilya [14]
Roots of the equation 3x² -3x-6=0 are -1 and 2,
all choices are given wrong
3*2²-3*2-6=0
12-6-6=0
0=0, which is true , so root is 2

3*20²-3*20-6=0
600-60-6=0
534=0  which is wrong, so root is 2, but not 20

Let f(x) = 8x3 − 22x2 − 4 and g(x) = 4x − 3. Find f of x over g of x
SVEN [57.7K]
F(x) = 8x³ - 22x² - 4
g(x) = 4x - 3

(f \div g)(x) = \frac{8x^{3} - 22x^{2} - 4}{4x - 3}
(f \div g)(x) = \frac{2(4x^{3}) - 2(11x^{2}) - 2(2)}{4x - 3}
(f \div g)(x) = \frac{2(4x^{3} - 11x^{2} - 2)}{4x - 3}

Answer:

The smaller number is: 8

The bigger number is: 20

Step-by-step explanation:

Ok let's say the two numbers are x and y.

x is the smaller one, and y is the bigger one.

This is the equation to find x:

x + 4y = 88

x + y = 28

x - x + 4y - y = 88 - 28

3y = 60

y = 20

x + 20 = 28

x = 8
