Answer:

-8/3

Step-by-step explanation:

We know that lines that are perpendicular have slopes that multiply to -1

m1 * m2 = -1

We know one slope is 3/8 and are looking for the perpendicular slope m2

3/8 * m2 = -1

Multiply each side by 8/3 to find m2

3/8*8/3 *m2 = -1*8/3

m2 = -8/3

Answer:

(Véase la explicación para mayores detalles/See the explanation for further details)

Step-by-step explanation:

a) Tres al cubo (Three to cube):

$x = 3 \times 3 \times 3$

$x = 3^{3}$

$x = 27$

b) Seis al cubo (Six to cube):

$x = 6 \times 6 \times 6$

$x = 6^{3}$

$x = 216$

c) Cinco al cuadrado (Five squared):

$x = 5 \times 5$

$x = 5^{2}$

$x = 25$

d) Ocho al cuadrado (Eight squared):

$x = 8 \times 8$

$x = 8^{2}$

$x = 64$

e) Dos a la quinta (Two to five):

$x = 2 \times 2 \times 2 \times 2 \times 2$

$x = 2^{5}$

$x = 32$

f) Diez a la cuarta (Ten to four):

$x = 10\times 10 \times 10 \times 10$

$x = 10^{4}$

$x = 10000$

Write the equation of the line that passes through the point (1,-1) and has a slope of -4

Phantasy [73]

Answer:

y= -4 x+3

Step-by-step explanation: A(1, -1)

the equation is y - y (A)=m*( x-x(A) )

y-(-1)=-4(x-1)

y+1=-4x+4

y= -4x+4-1

y=-4x+3

y=-4x+4-1

The picture shows 5 groups of 3 bars. Each bar represents 1/10. We take the picture to mean that ...

... (15/10) / 5 = 3/10

In decimal:

... 1.5 / 5 = 0.3

The picture shows 3 groups of 2 bars. Each bar represents 1/10. We take the picture to mean that ...

... (6/10) / 3 = 2/10

In decimal:

... 0.6 / 3 = 0.2

The picture shows 4 groups, each consisting of 1 large square, 1 bar, and 4 small squares. We take the picture to mean that ...

... (4 + 4/10 + 16/100) / 4 = 1 + 1/10 + 4/100

In decimal:

... 4.56 / 4 = 1.14

Please note that 16/100 is equivalent to 1/10 + 6/100. In order to do the division, one of the 1/10 bars needed to be changed into 10 small squares, 10/100.

The picture shows 3 groups, each consisting of 1 large square, 3 bars, and 2 small squares. We take the picture to mean that ...

... (3 + 9/10 +6/100) / 3 = 1 +3/10 + 2/100

In decimal:

... 3.96 / 3 = 1.32
