Answer:

7 units

Step-by-step explanation:

If the line is a straight line, count the number of units in between the two pints of the line.

If you count the units between the two pints on your screen, you will see that the answer is 7 units. This is because there are 7 units in between the two points of the line.

Transform the equation to isolate x: ax = bx + 1. How is the value of x related to the difference of a and b? The equation ax =

Sergeeva-Olga [200]

Answer:

Step-by-step explanation:

This is awfully hard to read. Use returns to separate paragraphs.

ax = bx + 1 Subtract bx from both sides.

ax - bx = 1 take out x as a common factor

x(a - b) = 1 Divide both sides by a - b

x = 1 / (a - b)

I think the second one is the one you want.

x is the same as the reciprocal of the difference between a and b.

Consider the following quadratic equation. -4x^2+bx-11=0 Determine a possible value of b so that the quadratic has two complex s

romanna [79]

Answer:

Step-by-step explanation:

hello,

for $ax^2+bx+c=0$

$\Delta = b^2-4ac$

so here

$\Delta = b^2-4*(-4)*(-11)=b^2-176$

to have two complex solutions we need $\Delta < 0\\$

so $b^2$

$b < \sqrt{176}=13.266...$

for instance we can take b = 0

hope this helps
