We cannot solve for a numerical value of p, but rather set the equation equal to p.

w = 4/(p+2)

(Multiply both sides by the denominator)

w(p+2) = 4

(divide both sides by w)

p+2 = 4/w

(Subtract 2 from both sides) (also 2/1)

p = (4-2)/w

p = 2/w

Which equation represents a proportional relationship? A) y = x 8 B) y = 8 x C) y = x 8 + 8 D) y = 8 x + 8

Liula [17]

Answer:

B y=8x

Step-by-step explanation:

A proportional relationship must go through the point x=0, y=0 and be in the form y=kx where x is a constant

A) y = x^8

B) y = 8 x

C) y = x^8 + 8

D) y = 8 x + 8

The only points that is in the form y= kx is option B

C and D do not go through x=0, y=0 and A is not in the form y=kx where k is a constant

After being rearranged and simplified, which of the following equations could be solved using the quadratic formula?

Alecsey [184]

For this case we must indicate which of the equations shown can be solved using the quadratic formula.

By definition, the quadratic formula is applied to equations of the second degree, of the form:

$ax ^ 2+ bx+ c = 0$

Option A:

$2x ^ 2-3x +10 = 2x + 21$

Rewriting we have:

$2x ^ 2-3x-2x+ 10-21 = 0\\2x ^ 2-5x-11 = 0$

This equation can be solved using the quadratic formula

Option B:

$2x ^ 2-6x-7 = 2x ^ 2$

Rewriting we have:

$2x ^ 2-2x ^ 2-6x-7 = 0\\-6x-7 = 0$

It can not be solved with the quadratic formula.

Option C:

$5x ^ 2 + 2x-4 = 2x ^ 2$

Rewriting we have:

$5x ^ 2-2x ^ 2 + 2x-4 = 0\\3x ^ 2 + 2x-4 = 0$

This equation can be solved using the quadratic formula

Option D:

$5x ^ 3-3x + 10 = 2x ^ 2$

Rewriting we have:

$5x ^ 3-2x ^ 2-3x + 10 = 0$

It can not be solved with the quadratic formula.

Answer:

A and C

∠K and ∠L are complementary angles. If m∠K = 3x + 3 and m∠L = 10x – 4, find the measures of both angles.

Oduvanchick [21]

Answer:

∠K =24

∠L =66

Step-by-step explanation:

first you need to find X in order to solve.

since they are Complementary they add together to equal 90 degrees

so we can set them equal to 90

13x-1=90

13x=91

x=7

now we can plug them in!

---

∠K = 3(7)+3 = 24

∠L =10(7)-4=66
