Step-by-step answer:
A line with slope (or gradient) m, passing through a point (x0,y0) can be represented by the equation:
(y-y0) = m(x-x0) ......................(1)
Here,
(x0,y0) = (1,7), and
slope/gradient = -2
Substitute values into (1) above gives
(y-7)=2(x-1)
Expand and simplify
y-7 = 2x-2
y =2x -2 + 7
y=2x+5
is the final answer.
Answer:
353 tickets.
Step-by-step explanation:
Let's say that there are s student tickets and n nonstudent tickets.
s + n = 669
5s + 8n = 4293
Multiply -5 by the entire first equation to get...
-5s - 5n = -3345
Combine the two equations.
5s - 5s + 8n - 5n = 4293 - 3345
3n = 948
n = 316
Now, put the number of nonstudent tickets sold back into the first equation.
s + 316 = 669
s = 353 tickets.
Hope this helps!
No less than or greater than signs are used, so C and D are out
In this case the equation starts as .45M + 3.50
The only matching statement is A
Answer:
2x = 10
Step-by-step explanation:
7 + 3x = 22
-7 -7
Subtract 7 from both sides (you are trying to get the variable alone, and to do that, you have to get every other number to 0. <em>7 - 7 = 0</em>. BUT, whatever you do, you have to do to both sides.)
3x = 15
/3 /3
Divide both sides by three to get the variable alone.
x = 5
Now, plug in the value of x to the second equation and solve.
2(5) = ? --> 10
