Determine the solution of the system. Show your work.<br> Y = 5x – 9<br> Y = 2x + 6
snow_tiger [21]
Both define y, so they are equivalent.

5x-9=2x+6
3x-9=6
3x=15
x=5

Then plug in x into any of the equations
y=2(5)+6
y=10+6
y=16

Final answer: (5,16)

Write the formula for the parabola that has x- intercepts (3,0) and (8,0), and y- intercept (0,−2)
alexira [117]

Answer:x^2-5x=-12(y+2)

Step-by-step explanation:

Given

Parabola has x-intercept has (3,0) and (8,0)

and Y-intercept as (0,-2)

Now the general equation of parabola is

y=ax^2+bx+c\quad \ldots(i)

Substitute  (0,-2) in (i) we get

-2=c

Now substitute (3,0) in equation (i)

0=a(3)^2+3b-2\quad \ldots(ii)

Now substitute (8,0) in equation (i)

0=a(8)^2+8b-2\quad \ldots(iii)

Solving (ii) and (iii) we get

a=\frac{-1}{12}\ \text{and}\ b=\frac{5}{12}

therefore

y=\frac{-x^2}{12}+\frac{5x}{12}-2

12y=-x^2+5x-24

A net and 4 figures are shown. Which figure shown can be formed from the net. ( input the number only) please answer quick and e
AfilCa [17]
A net is pretty much a three dimensional shape unfolded into a flat construction. Imagine cutting the edges of a box and unfolding it so you can lay it flat on the ground. That would form a net for the 3D shape of the box.
In this case, 1 and 2 obviously aren't right since they would both involve triangles in their net. 3 is close, but the parts of the net wouldn't be completely equal. Therefore it has to be 4, the cube.

To raise money for after-school programs at an elementary school, a group of parents is holding a weekend of games in a communit
frez [133]

Answer:

8x-40y\geq 600 and x>0,y>0

Step-by-step explanation:

The number of people is x and the number of hours they are present in the space is y.

Per person entry cost is $8.

Per hour cost of rent is $40.

They plan to earn a minimum of $600.

Donations by all the people entering the space is 8x

Total cost of renting the space is 40y which will be subtracted from the total amount of donations.

The inequality that represents the situation is 8x-40y\geq 600 and x>0,y>0.
