<h2>Step-by-step explanation:</h2>
-5/7 + x = -1
(-5+7x)/7 = -1
-5 + 7x = -7
7x = -2
<h2>x = -2/7</h2>

Answer:
Step-by-step explanation:
A=number Adult tickets;S=A+74= number Student tickets
Total tickets=adult tickets + student tickets
724=A+(A+74)
724=2A+74 Subtract 74 from each side
650=2A divide each side by 2
325=A ANSWER 1: There were 325 Adult tickets sold
Answer:
$24
Step-by-step explanation:
What you do is you just times 84 x 2/7 to get your answer.
84 x 2/7=$24 is your answer.
Answer:
Formula for area of triangle:
A = bh x 1/2
Formula for area of parallelogram:
A = bh
Now find the area of the figure above which is a triangle:
3(base) x 8(height) x 1/2 = <em>12</em>
Let's find the area of the parallelogram;
6(height) x 9(base) = <em>54</em>
Add the two areas together:
12 + 54 = 66 cm2
f(-1) = -11 and f(3) = -3 . these functions are true .
What does a math function mean?
- A relationship between a group of inputs and one output each is referred to as a function.
- A function is an association between inputs in which each input is connected to precisely one output.
- A domain, codomain, or range exists for every function. f(x), where x is the input, is a common way to refer to a function.
- In mathematics, a function is an expression, rule, or law that establishes the relationship between two variables (the dependent variable).
given function f(x) = 2x - 9
f(-1) = -11 ⇒ x = -1 put in function
f( -1 ) = 2 * -1 - 9 ⇒ - 11
f(2) = 5 ⇒ x = 2 put in function
f( 2 ) = 2 * 5 - 9 = 1
f(3) = -3 ⇒ x = 3 put in function
f ( 3 ) = 2 * 3 - 9 = -3
f(-3) = 15 ⇒ x = -3 put in function
f( -3) = 2 * -3 - 9 = - 15
