ILL GIVE BRAINIEST find the solption for each system of equations using substitution. check ur solution in both original equations and make sure equations are in slope intercept form before u set them equal

y= -2x+6 and y=3x-4

check:

Answers

Answer:

X= 2

y = 2

Step-by-step explanation:

y=-2x+6............... equation 1

y=3x-4................... equation 2

from equation 2

y=3x-4

substitute y=3x-4 in equation 1

3x-4=-2x+6

collect like terms

3x+2x=6+4

5x=10

divide both sides by 5

X=2

substitute X=2 in equation 1

y=-2x+6

y=-2(2)+6

y=-4+6

y=2

PLEASE HELP Review the equation, then complete the following. f(x)=1/x-4, g(x)=4x+1/x Use composition to prove whether or not the functions are inverses of each other. Express the domain of the compositions using interval notation.

Answers

Answer:A. Yes, they are inverse of each other.

B. Domain and range of the compositions is .

Step-by-step explanation:

A. We have, and .

Now, 'when two functions f and g are inverses of each other, they satisfy the property '.

So, we have,

Thus, we get for the given function f and g, .

Hence, they are inverse of each other.

B. Now, as we have,

That is, the composition of the functions is equal to the identity function.

Thus, the domain and range are the set of all real numbers respectively.

So, in the interval notation, we have,

Domain and range of the compositions is .

Solve the simultaneous equations
x + 5y = 16
x + 3y = 10

Answers

Answer: x=1 and y=3

Step-by-step explanation: hope this help

The solution of the linear equations x + 5y = 16 and x + 3y = 10 will be (1, 3).

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The linear equations are given below.

x + 5y = 16 ...1

x + 3y = 10 ...2

Subtract equation 2 from equation 1, then we have

x + 5y - x - 3y = 16 - 10

2y = 6

y = 3

Then the value of the variable 'x' will be given as,

x + 5(3) = 16

x + 15 = 16

x = 1

The solution of the linear equations x + 5y = 16 and x + 3y = 10 will be (1, 3).

More about the solution of the equation link is given below.

If an object was dropped from a height of 405 Meters,find the time it took for the object to hit the ground

Answers

Answer:You can use the concept of conservation of total mechanical energy (neglecting the air resistance).

So, initially total mechanical energy = gravitational potential energy (kinetic energy is zero because initially there is no velocity).

Final total mechanical energy = kinetic energy (gravitational potential energy is zero because height has become zero).

So, initial mechanical energy = Final mechanical energy

The Earth has a diameter
of 7,917.5 miles. What is
the distance a plane
would have to fly if it
could fly around the entire
equator?

Answers

Answer:

L = 24,873.6 miles

Step-by-step explanation:

Length of the Circumference

Given a circle of radius r, the length of the circumference, or line surrounding the shape is:

[tex]L =2\pi\cdot r[/tex]

The Earth has a diameter of 7,917.5 miles. The radius is half the diameter:

r=7,917.5/2=3,958.75 miles

Assuming a plane flies around the equator at ground level, the distance it would travel is:

[tex]L =2\pi\cdot 3,958.75\ miles[/tex]

L = 24,873.6 miles

25 points What is the equation for the line in slope-intercept form

Answers

Answer:

y=8x

Step-by-step explanation:

x=1 y= 8

x=2 y=16

8=m+b

16=2m+b

m=8

y=8x

Choose 2 coordinates from the line. Let’s pick (0,0) and (2,16)

The equation of a line is on the form y = mx + b where m is the slope and b is the y-intercept.

First let’s find the slope:

m = (y2-y1)/(x2-x1) = (16-0)/(2-0) = 16/2= 8

So we have y = 8x + b

We substitue one of the coordinates to find b. Let’s substitute (0,0)

We get 0 = 0 + b. So b = 0

The equation of the line is y = 8x
