i need to know what the answer is we have to combine like terms 10-4+6(4-2)

Answers

Answer:

18

Step-by-step explanation:

Solve the separate part of the equation first

6(4) 6(-2) would equal 24-12

Add it back in to get: 10 - 4 + 24 - 12

-4-12 and 10+24 are the like terms so

10+24 = 34 and -4-12 = -16

Equation in the end: 34-16

Simplify that to: 34-16 = 18

draw a line representing the rise and a line representing the run of the line. State the slope of the line in simplest form​

Answers

I’m not sure because I can’t see what you can do on your screen but by drawing a line representing rise and run- I think it means just draw a line rising up 3 and across 4. The slope is 3/4 so just create a line on x = -7 that goes up 3 and left 4.

Slope in simplest form I think means m = 3/4

The slope of lien is 3/4

What is Slope?

The slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line. The net change in y coordinate is Δy, while the net change in the x coordinate is Δx. So the change in y coordinate with respect to the change in x coordinate can be written as

m = Δy/Δx

where, m is the slope

Note that tan θ = Δy/Δx

Slope of a Line

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane. Calculating the slope of a line is similar to finding the slope between two different points. In general, to find the slope of a line, we need to have the values of any two different coordinates on the line.

According to given graph,

Take the co-ordinate (1, 6) and (5, 9)

slope= 9- 6/ 5-1

m=  3/4

What point is on both lines y=12x+3 and y=x+1

(no graph)

Answers

Step-by-step explanation:

by having two equations that have the same point, you can set the two equations equal to each other

y = 12x + 3, y = x + 1

12x + 3 = x + 1

11x = -2

x = -2/11

when you find the the x value, plug it back into either one of the equations

y = x + 1

y = (-2/11) + 1

y = 11/11 - 2/11

y = 9/11

the point (solution):

(-2/11, 9/11)

Answer:

(-2|11, 9|11)
