Answer:
r = -9
Step-by-step explanation:
use the slope formula:
(2-0) / (r-3) = -1 /6
cross-multiply:
-1(r - 3) = 2(6)
-r + 3 = 12
-r = 9
r = -9

Step-by-step explanation:
A band is playing at an auditorium with floor seats and balcony seats. The band wants to sell the floor tickets for $15 each and balcony tickets for $12 each. They want to make at least $3,000 in ticket sales.
4.Use technology to graph the solutions to your inequality and sketch the graph.
HELP WITH NUMBER 4!!!!!
THIS IS DUE AT 12!!!
(images included)
Answer: 15x + 12y ≥ 3000
Step-by-step explanation:
Number of floor seats tickets sold = x
Number of balcony seats tickets sold = y
Cost of floor tickets = $15
Cost of balcony tickets = $12
They want to make at least $3,000 in ticket sales.
At least in inequality means ≥
The inequality that represent the situation is
15x + 12y ≥ 3000
The inequality equation is 15x + 12y ≥ 3000
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Let the cost of one floor tickets be $ 15
So , the cost of x floor tickets = 15x
Let the cost of one balcony tickets be $ 12
So , the cost of y floor tickets = 12y
The minimum amount from the tickets = $ 3,000
So , the inequality is
15x + 12y ≥ 3,000 be equation (1)
On simplifying the equation , we get
5x + 4y ≥ 1000
Hence , the inequality is 5x + 4y ≥ 1000

The value of the expression is 43.5.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
3.5 + (1 + 4 x (6.5 + 1.5) )
= 3.5 + ( 5 x 8 )
= 3.5 + 40
= 43.5
Thus,

SOLUTION: a diver jumps from a diving board that is 24 feet above the water. the height of the diver is given by h= -16(t-1.5)(t+1) where the height h is measured in feet and the time t
Answer:
The diver will hit the water at 1.5 seconds
Step-by-step explanation:
Given
[tex]h= -16(t-1.5)(t+1)[/tex]
Required (Missing from the question)
When will the diver hit the water?
To do this, we simply solve for t
When the diver hits the water, the height is 0 (at that point)
So, substitute 0 for h in [tex]h= -16(t-1.5)(t+1)[/tex]
[tex]0= -16(t-1.5)(t+1)[/tex]
Divide both sides by -16
[tex]\frac{0}{-16} =\frac{-16(t-1.5)(t+1)}{-16}[/tex]
[tex]\frac{0}{-16} =(t-1.5)(t+1)[/tex]
[tex]0 =(t-1.5)(t+1)[/tex]
[tex](t-1.5)(t+1)=0[/tex]
Split
[tex]t - 1.5 = 0[/tex] or [tex]t + 1 = 0[/tex]
Solve for t
[tex]t = 1.5[/tex] or [tex]t = -1[/tex]
But time (t) can not be negative.
So:
[tex]t = 1.5[/tex]
Hence, the diver will hit the water at 1.5 seconds

Step-by-step explanation:
668 - 58 = 610
610 + 58 = 668
Answer:
t=610
Step-by-step explanation:
you need to get the exponent by itself, to do this:
t+58=668 becomes t=610 by subtracting 58 from both sides to balance it out (what you do to one side you have to do to the other)

if your friend said that his toy can accelarate uniformly at 1.5m/s²,what is its initial speed if you record its finalspeed as7.5m/s after 5.0s running?
[tex]a = \frac{vf - vi}{t} [/tex]
[tex]1.5 = \frac{7.5 - vi}{5.0} [/tex]
[tex]1.5(5.0) = \frac{7.5 - vi}{5.0} (5.0)[/tex]
[tex]7.5 = 7.5 - vi[/tex]
[tex]7.5 - 7.5 = 7.5 - 7.5 - vi[/tex]
[tex]0 = vi[/tex]
The car's initial speed is 0 m/s
