Answer:

y-3x-9=0

Step-by-step explanation:

(x1,y1)=(-3,0)and (x2,y2)=(-2,3)

Now,

y-y1=(y2-y1)/(x2-x1) (x-x1)

y-0=3-0/-2-(-3) (x-(-3))

y-0=3/1 (x+3)

y=3x+9

y-3x-9=0

liubo4ka [24]

Answer: $\bold{k=\dfrac{1}{9}}$

<u>Step-by-step explanation:</u>

The constant of proportionality is y = kx. Solve the given equation for "y" to find k-value in front of "x".

18y = 2x

$\dfrac{18y}{18}=\dfrac{2x}{18}$

$y=\dfrac{1}{9}x$

$k=\dfrac{1}{9}$

Pleaseee helppp!!!!!

lana [24]

Answer:

x - 9

Step-by-step explanation:

(f ÷ g)(x) = f(x) ÷ g(x), that is

$\frac{x^2-19x+90}{x-10}$ ← factorise the numerator

= $\frac{(x-10)(x-9)}{x-10}$ ← cancel the common factor (x - 10) on numerator/denominator

= x - 9

Y=2x+5 and y=3x+11 solve by substitution.

kondaur [170]

Answer:

Answer: x= -6 and y= -7

Step-by-step explanation:

Substitute 2x+5 for y in y=3x+11:

y=3x+11

2x+5=3x+11

2x+5+−3x=3x+11+−3x(Add -3x to both sides)

−x+5=11

−x+5+−5=11+−5(Add -5 to both sides)

−x=6

−x−1=6−1(Divide both sides by -1)

x=−6

Step: Substitute −6 for x in y=2x+5:

y=2x+5

y=(2)(−6)+5

y=−7(Simplify both sides of the equation)

Five children and one adult went to a concert adult tickets were 14 the total price of ticket was 59 what was the cost of each c

Bingel [31]

Answer:

9 (make sure to place the currency symbol (e.g. £ or $) beside your answer, otherwise it may be counted as incorrect).

Step-by-step explanation:

If one adult went and the adult tickets cost 14, we can subtract 14 from 59 to see the total cost of the children's five tickets:

59 - 14 = 45

Because there are 5 children, you then divide that value by 5 in order to find out the cost for one child and, ultimately, the cost of each child's ticket: 45 ÷ 5 = 9
The cost of each child's ticket is therefore 9
