Answer: Choice B

(3xy)^2 = (3xy)*(3xy) = (3*3)*(x*x)*(y*y) = 9x^2y^2

Explanation:

Steve correctly computed the change in x to be 2, and the change in y to be 6. However he put 2 in the slope formula for Δy (the change in y), and 6 for Δx. That is, Steve reversed the values of Δx and Δy.

The actual slope is ...

  slope = Δy/Δx = 6/2 = 3

Answer:

5x+3y=-1. A

6x-5y=16. B

3y=-5x-1

y=-5x/3 -1/3. C

sub C in B

6x-5(-5x/3 -1/3)=16

simplify:

6x+25x/3+5/3=16

Like terms

43x/3=43/3

cross multiply

129=129x

divide both sides by 129

X=1

sub X value in C

y=-5(1)/3 -1/3

y=-2.

Answer:

$1,650 profit

Step-by-step explanation:

It cost $15 to groom one animal, if you groom 95 animals you would do 95 animals x $15 = $1,425 profit. If you groom 110 animals and charge $15 per animal you would do the same equation. 110 animals x $15 =  $1,650. The equation for this problem is the number of animals groomed X the cost to groom one animal.

Hope this helps!

Answer and Step-by-step explanation:

I will try the best I can :3

if she started with 6, the first point you would put is (0,6)

this is how the equation would look:

y=___+6

(Tip: the number on the right is the y-intercept and the one on the left is the slope)

Now to find the slope: m=

y-y / x-x

Let’s use points (0,6) and points (2,8)

Rewrite to find slope: 8-6 / 2-0              =                 2/2 or 1

Now the equation should be:

y=1x+6

Step-by-step explanation:

[tex]\dfrac{23}{9} =2 \ \dfrac59= 2. \overline{5}=2.555555555...[/tex]

[tex]{ \rm{ \hookrightarrow{ \blue{ {x}^{2} + 6x + 9 }}}} \\ { \rm{ \hookrightarrow{ \red{ {x}^{2} - 9 }}}}[/tex]

Step-by-step explanation:

» General Quadratic expression:

[tex] { \rm{y = {x}^{2} - (sum \: of \: roots)x + (product \: of \: roots)}}[/tex]

» For (-3, -3), roots are -3 and -3

• Sum of roots:

[tex]{ \tt{sum = - 3 + - 3}} \\ { \tt{sum = - 6}}[/tex]

• Product of roots:

[tex]{ \tt{product = - 3 \times - 3}} \\ { \tt{product = 9}}[/tex]

• Equation:

[tex]{ \underline{ \underline{ \tt{ \: y = {x}^{2} + 6x + 9 \: }}}}[/tex]

» For (3, -3), roots are 3 and -3

• Sum of roots:

[tex]{ \tt{sum = - 3 + 3}} \\ { \tt{sum = 0}}[/tex]

• Product of roots:

[tex]{ \tt{product = - 3 \times 3}} \\ { \tt{product = - 9}}[/tex]

• Equation:

[tex]{ \underline{ \underline{ \tt{ \: y = {x}^{2} - 9 \: }}}}[/tex]

The system of two quadratic equation is

x² + 6x + 9 = 0

x² - 9 = 0

"A quadratic equation is an algebraic equation of the second degree in 'x'. The quadratic equation in its standard form is ax² + bx + c = 0, where 'a'(a ≠ 0) and 'b' are the coefficients, 'x' is the variable, and 'c' is the constant term."

The solution of the first equation in the system is (- 3, - 3).

Therefore, the equation will be

[x - (- 3)] [x - (- 3)] = 0

⇒ (x + 3)(x + 3) = 0

⇒ (x + 3)² = 0

⇒ x² + 6x + 9 = 0

The solution of the second equation in the system is (3, - 3).

Therefore, the equation will be

[x - 3] [x - (- 3)] = 0

⇒ (x - 3)(x + 3) = 0

⇒ (x)² - (3)² = 0

⇒ x² - 9 = 0

Answer:

JL ≈ 3.1

Step-by-step explanation:

Using the cosine rule

with JL = k , JK = l , KL = j , then

k² = j² + l² - (2jlcosK )

   = 6² + 8² - ( 2 × 6 × 8 × cos20° )

    = 36 + 64 - (96cos20°)

    = 100 - 96cos20° ( take square root of both sides )

k = [tex]\sqrt{100-(96cos20)}[/tex] ≈ 3.1 ( to the nearest tenth )

that is JL ≈ 3.1

Answer:

$12

Step-by-step explanation:

when d = 0,  F = 110

when d = 100, F = 110 + (0.12 x 100) = 122

when d = 200, F = 110 + (0.12 x 200) = 134

etc.

Therefore, increase in price for every 100 meters climbed = 134 - 122 = 122 - 110 = 12
