Hey there! Start with the slope formula, where 
and 
are the two known points.
Simplify.
Answer:
3) (0,-4) (4,0) (0,4) (-4,0) 4) (-2.5, 2.5) (5.5) (5.-3)
Answer:
14.
There are twice as many flute players as there are trumpet players, so f = 2 × 5
15.
Let the cost of 1 tickets = be x then the equation of total cost is:
8 × x = 208
Solve for x:
x = 208/8
x = 26
Each ticket costs $26.
16.
Let the low temperature be x then the equation for high temperature is:
x + 24 = 92
Solve for x:
x = 92 – 24
Evaluate:
x = 68
The low temperature was 68°F.
17. A number is checked if it is a solution of an equation or not by substituting its value in the equation and simplifying it. If the left and right hand side of the equation are equal then the number is a solution of the equation otherwise not.
Step-by-step explanation:
Answer:
7x^2 + 2x - 5
Step-by-step explanation:
(4x^2 + x - 9) + (3x^2 + x + 4)
7x^2 + 2x - 5
Pretty simple, just add 4 and 3, then x (or 1) and x, lastly -9 and 4. Then you get your final equation.
Step-by-step explanation:
a=110
b=110
c=70
d=70
e=110
f=70
