Answer:

A. x+1= 4x+5

Step-by-step explanation:

To solve the set of equation we can use substitution method.

Here the given set of equations are

Equation A : y=x+1

Equation B :y=4x+5

Now in substitution method we substitute y in terms of x from

first equation in to 2nd equation.

In other words we can also say that we equate both equations

so we have

y=x+1 = 4x+5

or we can also say that

x+1= 4x+5

hence the correct option is option A

Answer:

A

Step-by-step explanation:

y= x+1 at the same time y=4x+5

x+1= 4x+5, so answer is A

the sum of three numbers is 131. the third number is 4 times the first. the second number is 5 more than the first. what are the
Sphinxa [80]

Step-by-step explanation:

let the numbers are:

a, b, and c

the equation would be:

a+b+c = 131

c = 4a

b = a+5

=>

a + a+5 +4a = 131

6a +5 = 131

6a = 131-5

6a = 126

a= 126/6

a = 21

b = a+5 = 21+5

b = 26

c = 4a = 4(21)

c = 84

Solve the system using elimination: Help me please<br><br><br>12x - 8y = -12 <br><br>6x + 4y = -30
LUCKY_DIMON [66]

12x - 8y = -12  

6x + 4y = -30

Multiply the 2nd equation by 2, to make the Y coefficients opposite:

6x + 4y = -30 x 2 = 12x + 8y = -60

Now add the two equations:

12x -8y = -12 + 12x +8y = -60

=  24x = -72

Divide bothe sides by 24 to solve for x:

x = -72/24

x = -3

Now replace x with -3 in the first equation to solve for y:

12(-3) - 8y = -12

-36 - 8y = -12

Add 36 to each side:

-8y = 24

Divide both sides by -8 to solve for y:

y = 24 / -8

y = -3

X = -3 and y = -3

(-3,-3)

Helppppp meeeeeseseeeseeee
Ghella [55]

Step-by-step explanation:

Remember: Coplanar definition: In the same plane.

Here, we can see that points G, N, and M make up the intersection of plane K and plane L, so that means our answers are: G, N, and M because we were looking forth e points that are on planes K and L. The other points are not the answer because they are either on only one of the planes or not on any of them at all.

I hope this helps! :)
