Answer:

Option C is correct.

No solutions

Step-by-step explanation:

Given the system of equation:

y =2x-6               ....[1]

4x-2y=14             .....[2]

Substitute equation [1] into [2] we get;

4x-2(2x-6)=14

Using distributive property: a \cdot (b+c) = a\cdot b+ a\cdot c

4x-4x+12=14

Combine like terms;

12=14                False.

Therefore, there is no solution for the given system of the equations.

Sylvester says that 0.000002015 written in scientific notation is 2.015 x 10 by the power of 6. Do you agree with him? Explain w
Marrrta [24]

Answer:

0.000002015 is not equal to 2.015x10^6

Step-by-step explanation:

When a power of 10 is positive the dot must be moved to the right, and when the power of 10 is negative, the dot must be moved to the left.

For example 50.000x10^3=50000 and 45.00x10^{-3}=0.045

So

2.015x10^6=2,015,000

wich is clearly not equal to 0.000002015

the correct scientific notation for 0.000002015 must be:

2.015x10^{-6}

With a negative in the power of 10, referring to a small quantity.

1. Some roads in Poland have a speed limit of 140 km/h. How fast is this in miles per minute?
Y_Kistochka [10]
I only know number one here you goSolution
Conversion for Km to Miles
1km = 0.621 miles

Conversion Hours to minutes
1 hr = 60 mins

solve
140 (0.621 miles / 60 mins )
= 140 (0.01035 miles/min)
= 1.449 miles/min

What is the solution to the equation x2 +6x=40
eimsori [14]

Answer:

x=10  x=-4

Step-by-step explanation:

x^2 +6x = 40

subtract 40 from each side

x^2 +6x -40 = 0

what numbers multiply to -40 and add to 6

-10 *4 = -40       -10 +4 = 6


(x-10) (x+4) = 0

using the zero product property

x-10 = 0  x+4 =0

x=10      x=-4
