Answer:

Add 4K to both sides of the equation

Step-by-step explanation:

The goal is to isolate the variable.

What happens on one side of the equal sign must be done to the other like term on the other side of the equal sign.

k+6=-4k-9

To get rid of the 9 you must add 9 to its like term on the other side of the equation.

You shouldn’t add k to both sides of the equation because k is already positive and to cancel it out you must subtract k. (A variable has an inferred 1) (ex. 1k=k)

You also can’t subtract 4K from both sides of the equation because it is negative so the opposite of the negative would be to add the 4.

The only option that would be correct is the second one:

Add 4K to both sides of the equation because it will cancel out.

Write an inequality for x that would give this isosceles triangle and perimeter of at least 137 ft. 4x+3 2x+7

neonofarm [45]

Answer:

The inequality is $8x+17\geq 137$

Step-by-step explanation:

Given : The isosceles triangle with base and side 4x+3, 2x+7.

And the perimeter is at least 137ft.

To write : An inequality for x

Solution : Let the base $b=4x+3$ and sides $s=2x+7$

The perimeter of Isosceles triangle is $P=2s+b$

where s=side and b=base

Now, we have given that perimeter is at least 137 ft.

Therefore, the inequality form is

$2(2x+7)+(4x+3)\geq 137$

$4x+14+4x+3\geq 137$

$8x+17\geq 137$

Which statement describes the translation of y=-1/2(x-2)^2-2 from standard position?

Masteriza [31]

Y = x^2 is the parent function.
y = (x - 2)^2 would translate 2 units to the right
y = (x - 2)^2 - 2 would translate 2 units to the right and also 2 units down
y = - (1/2) (x - 2)^2 - 2
would reflect the parabola upside down, and also make it wider
