Answer:

16/21

Step-by-step explanation:

In the first fraction, the negative numerator and negative denominator cancel each other.

In the second fraction, the negative numerator and negative denominator cancel each other.

The equivalent equation is

8/9×6/7=?

For fraction multiplication, multiply the numerators and then multiply the denominators to get

8×6/9×7=48/63

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 48 and 63 using

GCF(48,63) = 3

4/8÷43/63÷3=16/21

Therefore:

−8/9× −6/7=16/21

(2.3 x 10 to the power of 4) times ( 1.5x10 to the power of minus 3) in standard form

Eduardwww [97]

Answer:

$3.45\times10$

Step-by-step explanation:

$(2.3 \times 10^{4}) \times ( 1.5 \times10^{-3} )= 2.3\times1.5\times10^{4}\times10^{-3}$

$= 3.45\times 10^{((4)+(-3))}$

$=3.45\times10$

a young hockey player on frictionless ice shoots a 1 kg hockey puck 150 m/s toward the goal. of the hockey player slides backwar

Dafna11 [192]

By conservation of linear amount of movement we have:
m1v1i + m2v2i = m1v1f + m2v2f
Where,
v1i = v2i = 0 (assuming initial rest)
m1v1f + m2v2f = 0
Substituting the values:
m1 (-3) + (1) (150) = 0
Clearing m1:
m1 = (- (1) * (150)) / (- 3)
m1 = 50 Kg
answer:
his mass is 50 Kg

How do you graph <br> y=3x and y=-x-8

laila [671]

Answer:

The points for the given two linear equation as

$x_1 , y_1$ = - 2 , - 6

$x_2 , y_2$ = - 2 , 6

The graph so plotted as shown

Step-by-step explanation:

Given as :

The two linear equation are

y = 3 x ........A and

y = - x - 8 .........B

Solving equation A and B

Now, Put The value of y from eq A into eq B

So, 3 x = - x - 8

Or, 3 x + x = - 8

Or, 4 x = - 8

∴ x = $\dfrac{-8}{4}$

I.e x = - 2

Now , Put the value of x into eq A

∵ y = 3 x

∴ y = 3 × (-2)

I.e y = - 6

Again, Put the value of x into eq B

∵ y = - x - 8

∴ y = - 2 - (-8)

I.e y = 6

So, for x = - 2 , y = - 6

And for x = - 2 , y = 6

Hence , The points for the given two linear equation as

$x_1 , y_1$ = - 2 , - 6

$x_2 , y_2$ = - 2 , 6

The graph so plotted as shown . Answer
