The slope of the line is 3/2  and y intercept is at (0,3) so the equation is

y = 3/2 x + 3  

or 3y = 2x + 9

Jamie is selling tickets at a whale watch at a local beach.The tickets cost $24.40 for an adult and $14.50 for a child.Jamie ear
wariber [46]
30% = .3

.3(24.40a + 14.50c)

24.40 = cost of adult ticket
14.50 = cost of child ticket
a = # of adult tickets sold
c = # of child tickets sold

.3 * 24.40a + .3 * 14.50c
answer: 7.32a + 4.35c

If a polynomial has one root in the form a+√b , it has a second root in the form of a_√b
gulaghasi [49]
When roots of polynomials occur in radical form, they occur as two conjugates.
That is,
The conjugate of (a + √b) is (a - √b) and vice versa.
To show that the given conjugates come from a polynomial, we should create the polynomial from the given factors.

The first factor is x - (a + √b).
The second factor is x - (a - √b).

The polynomial is
f(x) = [x - (a + √b)]*[x - (a - √b)]
      = x² - x(a - √b) - x(a + √b) + (a + √b)(a - √b)
      = x² - 2ax + x√b - x√b + a² - b
      = x² - 2ax + a² - b

This is a quadratic polynomial, as expected.

If you solve the quadratic equation x² - 2ax + a² - b = 0 with the quadratic formula, it should yield the pair of conjugate radical roots.
x = (1/2) [ 2a +/- √(4a² - 4(a² - b)]
   = a +/- (1/2)*√(4b)
   = a +/- √b
x = a + √b, or x = a - √b, as expected.

The points (−3, r)  and (2, 1) lie on a line with slope −2 . Find the missing coordinate r .
SVETLANKA909090 [29]
We can use point slope form to solve for this.

y - 1 = -2(x - 2)
Simplify.
y - 1 = -2x + 4
Add 1 to both sides.
y = -2x + 5

Now, we can input -3 for x and solve for y, or r in this case.

y = -2(-3) + 5
y = 6 + 5
y = 11

r = 11

rosijanka [135]

Answer:

technological

Step-by-step explanation:

According to my research on studies conducted by various sociologists, I can say that based on the information provided within the question this is an example of a trend within the technological environment. This is because technology helps create opportunities as well as allowing new ways of doing certain things. Like in this case finding bottle filling stations.

SungHee empties her piggy bank and finds that that she has 200 quarters 150 dimes and 300 pennies. How much money does she have
gayaneshka [121]
A quarter = 0.25......200 quarters = 200(0.25) = $ 50
a dime = 0.10...150 dimes = 150(0.10) = $ 15
a penny = 0.01....300 pennies = 300(0.01) = $ 3

for a total of : 50 + 15 + 3 = $ 68
