Answer:

Step-by-step explanation:

We can simplify (cross multiply) to get $xy^2=wz$

Then we easily simplify to get $y=\sqrt{\frac{wz}{x}},\:y=-\sqrt{\frac{wz}{x}};\quad \:w\ne \:0,\:x\ne \:0$

Side AB of parallelogram ABCD has endpoints at (-1,6) and (6,9). What is the slope of the opposite side, CD?

Butoxors [25]

Answer:

3/7

Step-by-step explanation:

Opposite sides on a parallelogram are parallel, and parallel lines have the same slope, so once we find the slope of AB, we'll know the slope of CD. Point A is (-1,6) and point B is (6,9), so the slope of AB (and by extension, CD) is

$\dfrac{9-6}{6-(-1)}=\dfrac{3}{7}$

Can someone pls help need it ASAP and can you pls explain in full detail how to do it

GenaCL600 [577]

Answer:

x= 1 , y=4

Step-by-step explanation:

x-y= -3 => Equation 1

x+5y= 21 => Equation 2

Substitution Method:

Substitute Equation 1=>

x=y-3 <= Equation 3

Put x=y-3 in Equation 2:

x+5y=21

( y-3)+5y=21

y-3+5y=21

6y-3=21

6y=21+3

6y=24

y=24÷6

y=4

Put y=4 in Equation 1:

x-y= -3

x-4=-3

x=4-3

x=1

Hope this helps :)

balu736 [363]

Answer:

B. -7j-k-1

Step-by-step explanation:

Simplify:

1. IDENTIFY LIKE TERMS

10k+17-7j-18-11k

10k and -11k are like terms since they have the same variable.

17 and -18 are like terms since they are regular numbers.

-7j has no like terms.

2. COMBINE LIKE TERMS

-7j-k-1
