Answer:

4y+3\leq y+6

We solve for y

4y-y\leq 6-3\\3y\leq 3\\y\leq 1

The solution set is all number less or equal than 1. Its graph is C, because it shows the right solution set.

-2y>2\\y

The solution set is all numbers less than -1. Its graph is A, because it represents all number less than -1. (The empty circle means that -1 is not part of the solution set, which is true)

\frac{y}{3}

The solution set is all numbers less than -3. Its graph is D.

3y\leq 2y+3\\3y-2y \leq 3\\y \leq 3

The solution set is all numbers less or equal than 3. Its graph is B, because it shows exactly the solution set.

X^2 + x^2=6^2 what is x​
nikitadnepr [17]

Answer:

x = ±3 sqrt(2)

Step-by-step explanation:

x^2 + x^2=6^2

Combine like terms

2x^2 = 6^2

Divide each side by 2

x^2 = * 6^2/2

Take the square root of each side

sqrt(x^2) =± sqrt(  6^2/2)

Remember that sqrt(a/b) = ±sqrt(a ) /sqrt(b)

x = ±sqrt(6^2)/sqrt(2)

x = ±6 /sqrt(2)

We do not leave square roots in the denominator, so we multiply the top and bottom by sqrt(2)

x = ±6 /sqrt(2) * sqrt(2)/ sqrt(2)

x = ±6 *sqrt(2) /( sqrt(2)*sqrt(2))

x =  ±6 sqrt(2) /(2)

x = ±3 sqrt(2)

Through: (4, -3), perp. to y=-2x + 1
larisa86 [58]

Step-by-step explanation:

y = -2x + 1. => Slope = -2

Then the perpendicular line will have a slope of -1/(-2) = 0.5.

We have y = 0.5x + c.

When x = 4, y = -3.

=> (-3) = 0.5(4) + c, c = -5.

Hence the answer is y = 0.5x - 5. (C)
