A table would help to organize more information than a graph would. A graph would help more with numbers.

find the equation of a line that is parallel to the straight line 2x-y=-3 and crosses the x-axis at x=-5

Alecsey [184]

Answer:

y=2x+10

Step-by-step explanation:

In line equations its helpful to write your line in the form y = ax + b. This helps because a is always the gadient of the line and b is always the y intercept.

In this case it is y=2x+3

All parallel lines have the same gradient. The gradient of this line = 2.

If the line crosses the x axis at x=-5, then when x =-5 y = 0.

If you put all this in the form y =ax + b you get 0 = 2(-5) +b

So all you need to do to find b is rearrange. b = 10.

Therefore your line has gradient 2 and y intercept 10.

y = 2x + 10

Solve the equation x^13-2x^12-x^11+2x^10=0 in the real number system

Lemur [1.5K]

Answer:

x= -1, x=1 and x=2

Step-by-step explanation:

The equation is;

$x^{13} -2x^{12} -x^{11} +2x^{10} =0$

Using a graph tool to graph the equation and identify the solution you will have;

x= -1,

x=1

x=2

Check answers

when x=2

$2^{13}-2(2^{12} )-2^{11} +2(2^{10} )\\\\\\2^{13} -2^1(2^{12} )-2^{11} +2^1(2^{10} )\\\\\\2^{13} -2^{13} -2^{11} +2^{11} =0$
