I would say based on Lincoln's success and that Lincoln helped inspire Martin. Lincoln won the Civil War which helped open the minds of other people who were pro-slavery so that's what I mean about the success.

I need help with these two problems.
Dennis_Churaev [7]

Answer:

the equation is - y=x

Explanation:

Given -

y=x+4

We have to find a line passing through the point (2,2) nd parallel to the given line.

Find the slope of the given line.

It is the coefficeint of x

m₁ = 1

The two lines are parallel. Hence

m₂=m₁=1 Where m₂is the slope of the second line.

You have slope and the points (2,2)

Find the Y intercept

y=mx+c\\2=(1)(2)+C\\2=2+C\\C=2-2=0

Y-Intercept C=0 and slope m₂=1

Fix the equation

y=x

Which of the following equations shows how substitution can be used to solve the following system of equations?
igor_vitrenko [27]

Answer:

(3, 5)

Step-by-step explanation:

y = 2x - 1

3x + 2y = 19

In the second equation, substitute 2x - 1 in for y, since y equals 2x - 1 in the first equation. Solve for x.

3x + 2(2x - 1) = 19

3x + 4x - 2 = 19

7x - 2 = 19

7x - 2 + 2 = 19 + 2

7x = 21

7x/7 = 21/7

x = 3

Pick the first equation to solve for y since it says y =. Substitute 3 in for x.

y = 2x - 1

y = 2(3) - 1

y = 6 - 1

y = 5

Kiley went 5.7 km/h north and then went 5.8 km/h west. From start to finish, she went 8.1 km/h northwest to find Maya Rodriguez.
enot [183]

Answer:

  • D. 5.7 km/h north and 5.8 km/h west are instantaneous velocities, while 8.1 km/h northwest is the average velocity.

Step-by-step explanation:

We are given directions and position change.

This is about the velocity, the speed doesn't take into account the direction.

We also see the change in the velocity. The numbers give us instantaneous velocities and the displacement is the average velocity as the sum of vectors.

Considering the above explanation, correct choice is D.

Which is an equation of the line that passes through the points (5 15) and (10 20)?
faust18 [17]
The generic equation of the line is:
 y-yo = m (x-xo)
 Where,
 m = (y2-y1) / (x2-x1)
 Substituting values:
 m = (20-15) / (10-5)
 m = (5) / (5)
 m = 1
 We choose an ordered pair:
 (xo, yo) = (5, 15)
 Substituting values:
 y-15 = 1 (x-5)
 y = x - 5 + 15
 y = x + 10
 Answer:
 
An equation of the line that passes through the points (5 15) and (10 20) is:
 
y = x + 10
