Answer:

9

Step-by-step explanation:

We know that a=1/5. Therefore, we can substitute 1/5 in for a into the expression.

10a + 7

10(1/5)+7             <em>Multiply 1/5 and 10</em>

2+7                    <em>Add 2 and 7 </em>

9

Heya!

Here is your answer:

2 × 3^{2} +10

we know that,
3^{2} = 9

so,

2×9 +10

According to BODMAS (bar, Order, division, multiplication, addition, subtraction)

we multiply 2×9 = 18

then,

18+ 10
= 28

Which graph shows y= (-5x) -4?
Leya [2.2K]

Answer:

Graph A

Step-by-step explanation

I look at the y-intercept first, and the y-intercept is -4, so looking at each graph you can see both A and D have y-intercepts of -4, since the line intercepts, or goes through the y-axis (the vertical line of the graph) at -4.

Then, you look at the variable that's changing, which is -5x. Since it's a negative, A is the graph that is negatively decreasing, because of its position on the graph. The line is going down, starting in the negative side.

Answer: The travel services sector is made up of a complex web of relationships between a variety of suppliers, tourism products, destination marketing organizations, tour operators, and travel agents, among many others. Under the North American Industry Classification System (NAICS), travel services comprises businesses and functions that assist with planning and reserving components of the visitor experience (Government of Canada, 2014).

!!!!!!!!!I AM CRYINGGGG!!!!!! PLZZZZ
andrey2020 [161]

Answer:

-x^2-2x-3

Step-by-step explanation:

  • Question 1: Just substitute in the values of f(x) and g(x) and simplify!

  1. f(x) - g(x) = 4x^2-5x+3-(5x^2-3x+6)
  2. f(x)-g(x) = 4x^2-5x+3-5x^2+3x-6
  3. f(x)-g(x) = -x^2-2x-3

Tell me if this helps, and if you still need number 2 or if you can do it by yourself! (Hint: substituting also plays a role in question number 2.)

Hope this helps!!
