Answer:
-6
Step-by-step explanation:
Plug in (-1) for y: -3(-1) - 9
Simplify: Negative x Negative = Positive
-3(-1) = 3 so... 3-9
3 - 9 = -6
-3y - 9 is equivalent to -6
Answer:
Step-by-step explanation:
-3(-1)-9
3-9=-6
-6≠-9
-6 is not equivalent to -9

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]

In the coordinate plane, when you move an ordered pair (x,y) to the right, _______
A) the x values get larger
B) the x values get smaller
C) the y values get larger
D) the y values get smaller
What's the answer?
The x values get larger when you move (x, y) to right side. Therefore, option A is the correct answer.
What is the translation?A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.
Here,
Translation rules:
When the shape is moved towards the right by k units, then replace x with x + k.
When you move the ordered pair (x, y) to right, x value gets increased.
Therefore, option A is the correct answer.

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.

Step-by-step explanation:
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.
