Select the correct answer. What is the difference of the values of the two variables in this system of equations? Y = 2x + 1 x +
zzz [600]

Answer:

Option C. 2

Step-by-step explanation:

we have

y=2x+1 -----> equation A

x+3y=10 -----> equation B

Solve the system of equations by graphing

Remember that the solution of the system of equations is the intersection point both graphs

The intersection point is (1,3)

see the attached figure

therefore

The solution of the system of equations is

x=1,y=3

Find the difference

y-x=3-1=2

Three times the sum of a number and 4 is the same as 18 more than the number. what is the number​
____ [38]

Answer:

three times the sum of a number and 4, if n were to represent the unknown number, is:

3(n + 4)

18 more than a number is:

n + 18

If these two are the same, then they are equal to each other, then:

3(n + 4) = n + 18

*Do the distributive property on the left*

3n + 12 = n + 18

*Combine like terms*

2n = 6

*Divide both sides by 2*

n = 3

The number is 3.

A line passes through (2, –1) and (8, 4). a. Write an equation for the line in point-slope form. b. Rewrite the equation in stan
pentagon [3]
The point-slope form of a line is:

y-y1=m(x-x1),  where m=slope and (x1,y1) is any point on the line

First we need to find the slope, which is (y2-y1)/(x2-x1)

m=(4--1)/(8-2)

m=5/6 and we can use either point, I'll use (8,4)

y-4=(5/6)(x-8)

That is your equation in point-slope form.

Now the standard equation of a line is ax+by=c

y-4=(5/6)(x-8)  we can perform the indicated multiplication on the right side

y-4=(5x-40)/6  multiply both sides by 6

6y-24=5x-40  add 24 to both sides

6y=5x-16  subtract 5x from both sides

-5x+6y=-16  and by convention, the standard equation of a line should be expressed with a positive coefficient for x, so multiply both sides by -1

5x-6y=16
