If a and b are zeroes of the x2 + 7 x+7, find the value of a−1+b−1−2ab.

Answers

9514 1404 393

Answer:

-15

Step-by-step explanation:

If 'a' and 'b' are zeros of the quadratic f(x), its factored form is ...

f(x) = (x -a)(x -b)

and its standard form is ...

f(x) = x^2 -(a+b)x +ab

This tells us that ...

a+b = -7

ab = 7

for the given quadratic.

Then the expression of interest is ...

[tex]a^{-1}+b^{-1}-2ab=\dfrac{1}{a}+\dfrac{1}{b}-2ab=\dfrac{a+b}{ab}-2ab\\\\=\dfrac{-7}{7}-2\cdot7=-1-14=\boxed{-15}[/tex]

Solve the system of equations by substitution:
3n + 5m = 7
m - 4n = 6

Answers

Answer:

m=2, n=-1 or (2,-1)

Step-by-step explanation:

Hi there!

We're given this system of equations:

3n+5m=7

m-4n=6

we want to solve by substitution; in one equation, we'll set one variable to equal an expression containing the other variable, substitute that expression as the variable into the other equation, solve for the variable substituted, and use the value of that variable to find the other variable

First, let's get the expression we'll substitute into the other

let's use m-4n=6 as it has 1m (m by itself)

add 4n to both sides

m=4n+6

now substitute 4n+6 as m into 3n+5m=7 to solve for n

3n+5(4n+6)=7

do the distributive property

3n+20n+30=7

combine like terms

23n+30=7

subtract 30 from both sides

23n=-23

divide both sides by 23

n=-1

we found the value of n

now let's substitute -1 as n in m=4n+6 to find the value of m

m=4(-1)+6

multiply

m=-4+6

add

m=2

so the answer is m=2, n=-1. As a point, it's (2,-1)

Hope this helps! :)

The gravitational attraction F between two objects of masses m1 and m2 is jointly proportional to the masses

This means that:

[tex]F = k\frac{m_1m_2}{}[/tex]

Answer:

31.3

Step-by-step explanation:

Reference angle given = 56.1°

Hypotenuse = 56.1

Adjacent side = x = ?

We would apply CAH, which is:

Cos 56.1° = Adj/Hyp

Cos 56.1° = x/56.1

56.1 × Cos 56.1° = x

31.2895006 = x

x = 31.3 (approximated to the nearest tenth)

Two angles are supplementary. One is 25° more than four times the other. Find the measures of the angles.

Answers

Answer:

100

Step-by-step explanation:

I believe it is this answer bur don't hold me to. If it is wrong I'm sorry in advance

Answer:

The two angles are 31° and 149°

Step-by-step explanation:

Let the two supplementary angles be , x and y.

Then, x + y = 180° ----- ( 1 )

Given : one is 25° more than 4 times other

Let y = 25° + 4x ------ ( 2 )

Substitute ( 2 ) in ( 1 ) :

x + y = 180°

x + 25° +4x = 180°

x + 4x = 180° - 25°

5x = 155°

x = 31°

Substitute x in ( 2 ) :

y = 25° + 4x

= 25 + 4 ( 31 )

= 25 + 124

= 149°
