B = 0  beacuse that would make -7b = 0   and 1 / 0 is indeterminate.

Find positive numbers x and y satisfying the equation xy=20 such that the sum 4x+y is as small as possible.
omeli [17]
The answer is 4 and 5.

They are 2 positive numbers that satisfy the equation, (5)(4)=20.

If that doesn’t work try 2 and 10.

Hope this works!! :)

Which answer shows this equation written in standard form?
Iteru [2.4K]
So first we solve and simplify
pemdas
first parenthasees

9-4(x-y)=-6x+6
distribute using distributeive property of multiplication which is a(b+c)=(ab)+(ac)

so -4(x-y)=-4x+4y

9-4x+4y=-6x+6
add 6x to both sides
9+2x+4y=6
subtract 9 from both sides
2x+4y=-3
only B matches this
B is the correct answer

(I don't know what standard form is but I know what simplified is)

Write the equation of a line that is parallel to y= -6x+2 that passes through the point (-2,-3)
MissTica

Answer:

y = - 6x - 15

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 6x + 2 ← is in slope- intercept form

with slope m = - 6

Parallel lines have equal slopes then

y = - 6x + c ← is the partial equation

To find c substitute (- 2, - 3 ) into the partial equation

- 3 = 12 + c ⇒ c = - 3 - 12 = - 15

y = - 6x - 15 ← equation of parallel line
