Someone help pleaseee

1 answer:

5 0

The answer would be 40
Explanation: let’s say x is over y
It took 0.4 times 80 to get 32 which means it would be 0.4 times 100 to get 40

Answer:

1 / y^7

Step-by-step explanation:

Y^-9•y^-8•y^10

= y^10 / y^9•y^8

= y^10 / y^17

= 1 / y^7

Slope intercepts No links, Will mark BRAINLIEST

Sergeeva-Olga [200]

Answer:

Lines are perpendicular to each other .

Step-by-step explanation:

Standard equation of line is : y = mx + c, Where m represents the slope

Given Equations :

$y = -5x + 1\\\\Slope , m_1 = -5$

$y = \frac{1}{5}x +1\\\\Slope, m_2 = \frac{1}{5}$

Two lines are parallel if the slope of the lines are same.

Two line are perpendicular if the product of the slope = - 1

Clearly slopes are not equal , therefore the lines are not parallel.

product of the slope is - 1, therefore the lines are perpendicular.

$m_1 \times m_2 = -5 \times \frac{1}{5} = - 1$

Suppose A is an invertible n×n matrix and v is an eigenvector of A with associated eigenvalue 4. Convince yourself that v is an

mote1985 [20]

The eigenvector of matrix A4 is 4096.

The eigenvalue of the matrix A-1 is 1/8.

(A+4I) has an eigenvalue of 12.

40 is the eigenvalue of 5Av.

The collection of scalar values known as the eigenvalues of a matrix are connected to the set of linear equations that are most likely contained within the matrix equations.

The eigenvectors are also known as the characteristic roots.

If the matrix A's eigen vector v is linked to an eigen value.

Av then equals lamda v.

The fact that v is an eigen vector of A with the value eight is assumed.

hence, Av = 8v.

We must determine the eigenvalue of A4.

A4*v equals A3(8v) = 84*v equals 4096v.

As a result, the eigenvalue of A4 is 4096.

Suppose A has an eigenvalue of 8. The eigenvalue of A-1 is thus 1/8.

It is calculated that the eigenvalue of (A+4I) is (A +4In)v = Av + 4v = 8v + 4v =12v.

(A+4I) has an eigenvalue of 12.

The value of 5Av's eigenvalue is 5Av = 5*8v = 40v.

40 is the eigenvalue of 5Av.

What is the equation of the line that passes through the point (4, -2) and has a slope of -22

Nina [5.8K]

Answer: the answer is y=-22x+86

here is why:

the slope is -22 which is the m --> y=mx+b the point is (4,-2) the x=4 and y= =2

If we set up the equation:

-2= -22(4)+86

-2= -88+86

-2= -2
