Answer: A) x - 4 = 0 and this is an undefined slope which is a vertical line

Step-by-step explanation:

If the slope of a line is undefined, then the line is a vertical line, so it cannot be written in slope-intercept form, but it can be written in the form: x=a , where a is a constant.

Find the unknown factor. 28=7 x (4 x

Sveta_85 [38]

Answer:

The missing factor is 1.

$28=7\times(4\times1)$

Step-by-step explanation:

$28=7\times(4\times y)$ , where y is the unknown factor.

You can solve this equation for y.

Divide both sides by 7:

$\rightarrow 28\div7=(7\times(4\times y))\div7\\\rightarrow4=4\times y$

Divide both sides by 4:

$\rightarrow4\div4=(4\times y)\div4\\\rightarrow1=y\\\rightarrow y=1$

The missing factor is 1.

$28=7\times(4\times1)$

You can also tell just by looking on this particular problem. $7\times4=28$ , so the missing factor can't be anything other than 1.
