Five friends went to Madrid. The return flight was $25 more than the outgoing flight. Airport taxes were $21 for each flight for each person. The overall cost was $595. What was the price of the return flight for each person?
Answer:
$98
Step-by-step explanation:
21 × 5 ( since there are 5 friends )
= 105
595 - 105 = 490 (total cost for all 5 of the return flight)
490 ÷ 5 = 98
$ 98 for each person.

Answer:
The required equation in factored form is: [tex]\mathbf{y=-4(x+2)(x-1)}[/tex]
Step-by-step explanation:
In this question we need to find the equation of the graph in factored form.
The factored form will be: [tex]f(x)=a(x-r_1)(x-r_2)..[/tex]
where a is y-intercept and r₁, r₂ are x-intercepts
X-intercepts
When y=0, the values of x axis are known as x-intercepts
Y-intercepts
When x=0, the values of y-axis are known as y-intercepts.
Looking at the graph finding x-intercepts
When y=0 x=-2 and 1
So, we have
r₁ = -2
r₂ = 1
Looking at the graph finding y-intercepts
When x=0, y=-4
So, a = -4
Putting values in the formula we will get:
[tex]f(x)=a(x-r_1)(x-r_2)\\f(x)=-4(x-(-2))(x-1)\\f(x)=-4(x+2)(x-1)[/tex]
So, the required equation in factored form is: [tex]\mathbf{y=-4(x+2)(x-1)}[/tex]

Solve the system by substitution.
y = -3x + 4
y = -7x
Submit Answer
Answer:
{y,x} = {7,-1}
Step-by-step explanation:
(-7x) + 3x = 4
- 4x = 4
4x = - 4
x = - 1
y = -7x
x = -1
y = -7(-1) = 7
is the problem 6y2x=10 in standard form
Answer:
Yes, yes it is.
Answer:
No it is not
Step-by-step explanation:
If you were to write 6y2x=10 in standard form it would be
y=√15x/3x
or
y=-√15x/3x

Kyle is buying a book online for $14.58. It is on sale for 10% off. What is the sale price with a 8.25% tax?
First, find the discount by finding 10% of $14.58. To do this, convert 0% into a decimal and multiply by $14.58.
14.58 x 0.1 = 1.458.
Since this a sale price, how much he is getting off, subtract from the total.
14.58 - 1.458 = 13.122.
We still have to find the sales tax. Solving is similar to finding the discount.
13.122 x 0.0825 = 1.082565.
Now, since it is a tax, add to the total.
13.122 + 1.082565 = 14.204565
Round to the nearest hundredth, and you have $14.20.
The sale price with after tax is $14.20.
Find the slope, or rate of change:

Answer:
y= -1/2x
Step-by-step explanation:
y-y1/x-x1=y2-y1/x2-x1
y-1/x+2=-1/2
2y-2= -x-2
2y= -x-2+2
2y=-x

Answer:
m1 =131 degrees
m2=49 degrees
Step-by-step explanation:
Alternate interior angles are always congruent, so they will be equal to each other, so m1=131 degrees.
Straight angles always add up to 180 degrees, so 180-131=49, so m2=49 degrees
