Answer:
52 tickets cost $10 and 18 tickets cost $12
Step-by-step explanation:
10x+12y=804. (1)
x+y=70. (2)
From (2)
x=70-y
Substitute x=70-y into (1)
10x+12y=804
10(70-y)+12y=804
700-10y+12y=804
700+2y=804
2y=804-700
2y=104
y=104/2
y=52
Recall
x+y=70
x+52=70
x=70-52
x=18
52 tickets cost $10 and 18 tickets cost $12
The solution to the inequality |4x − 2| > 14 is x > 4 and x < -3
<h3>What is an
inequality?</h3>
An inequality is an expression that shows the non equal comparison of two or more numbers and variables.
Given the inequality:
|4x − 2| > 14
Hence:
4x - 2 > 14 or -(4x - 2) > 14
x > 4 or x < -3
The solution to the inequality |4x − 2| > 14 is x > 4 and x < -3

Answer:
The standard form of the parabola is 
Step-by-step explanation:
The standard form of a parabola is
.
In order to convert
into the standard form, we first separate the variables:

we now divided both sides by 2 to remove the coefficient from
and get:
.
We complete the square on the left side by adding 3 to both sides:



now we bring the right side into the form
by first multiplying the equation by
:

and then we multiplying both sides by
to get
.
Here we see that


Thus, finally we have the equation of the parabola in the standard form:
