Mathematics
1 answer:
Kryger [21]3 years ago
6 0
The two numbers are (5+ √(129))/2 and (5-√(129))/2.

(5+ √(129))/2+ (5-√(129))/2= 5
(5+ √(129))/2* (5-√(129))/2= -26

Hope this helps~

Otrada [13]

Answer:

Step-by-step explanation:

For the given piecewise function,

Let the equation of the segment AB is,

y = ax + 7 where x < -2

Since a point (-2, 3) lies on the given line,

3 = a(-2) + 7

3 - 7 = -2a

a = 2

Therefore, f(x) = 2x + 7 when x < -2

For the segment BC,

f(x) = 3 where -2 ≤ x ≤ 2

For the segment CD,

f(x) = bx + 9

Since a point (2, 3) lies on this segment,

f(2) = 2b + 9 = 3

2b = 3 - 9

b = -3

Therefore, equation of segment CD will be,

f(x) = (-3)x + 9   where x > 2

What is the solution to this system of equations? 3x + 2y=45 , 4x-y=5
sleet_krkn [62]
The solution is (5, 15)

Multiply the second equation by 2 and then add through. 

3x + 2y = 45
8x - 2y = 10
-----------------
11x = 55
x = 5

Then plug in to get the y value

3(5) + 2y = 45
15 + 2y = 45
2y = 30
y = 15

yawa3891 [41]

Answer: SIMPLIFY TERMS === 32X^3-12X^2+51X=35

Step-by-step explanation:

(4x2+x+7)(8x−5)

Expand (4x2+x+7)(8x−5)

by multiplying each term in the first expression by each term in the second expression.

4x2(8x)+4x2⋅−5+(x(8x)+x⋅−5)+(7(8x)+7⋅−5)

Simplify terms.
