It is telling me to graph the points y = 1/2x - 4. Can you guys maybe draw this out for me?(plot the points). Will mark Brainlie

Marina CMI [18]

Answer:

(-1,-9/2)(0,-4)(1,-7/2)(2,-3)

Step-by-step explanation:

In fact you just need to do the calcuolation step

when x= -1,y=1/2 *-1 -4=-9/2

when x=0 y=1/2*0-4= -4

when x=1 y=1/2*1-4=-7/2

when x=2 y-1/2 *2-4=-3

Determine the non-permissible value(s) of the variable(s).

Serga [27]

Answer:

i) the value of a = 0 is non-permissible

ii) the value of b = 0 is non-permissible

Step-by-step explanation:

i) the given expression is $\frac{5a^{2} + 80a }{50ab^{2} }$

ii) if a = 0 then the expression will become infinity hence the value of a = 0 cannot be used

iii) if b = 0 then the expression will become infinity, hence the value of b = 0 also cannot be used.

iv) In the numerator of the expression if it is factorized we get 5a $\times$ ( a + 16)

if a = -16 then the value of the expression becomes zero.

Can I get some help with the first one. 6p^3-12p^2+9p

Gelneren [198K]

Hi there!

The answer is:
$6p {}^{3} - 12 {p}^{2} + 9p = 3p(2 {p}^{2} - 4p + 3)$

We can find this answer by writing the factors.
$6 {p}^{3} = 3 \times 2 \times p \times p\times p$
$- 12 {p}^{2} = 3 \times - 4 \times p \times p$
$9p = 3 \times 3 \times p$

Now we can see that the terms that are in common are 3 and p. Therefore, the GCF is 3p.

Please I need help ............... .

Answer & Steps:

I just left everything in fraction form unless it's equal to a whole number. Wasn't sure how you wanted it to be simplified

16) $\frac{2}{3}$ + $\frac{1}{4}$ = $\frac{8}{12}$ + $\frac{3}{12}$ = 11/12
