6 0

Step-by-step explanation:

-4x+5>-5

    -5   -5

-4x>-10

/-4   /-4

x<2/5

You switch the sign whenever you divide a negative. In this case, we did, so instead of it being x>2/5, the answer is x<2/5.

hope it helps! :3

On a coordinate grid, 1 square unit equals 14 square mile. A rectangular walking path has vertices at (−4, 5) (1, 5), (−4, -5) a
AfilCa [17]

Answer:

126 square miles

Step-by-step explanation:

So I just draw a grid and mark the thingies (sorry my math vocabulary is not very good)

So you get a rectangle that is 5x9 if you connect the dot thingies and 9 square units is 14 square miles and 9x14=126. Using a coordinate grid makes it easier to visualize what you’re doing

Consider the rule y = 5x + 7.
maksim [4K]

Answer:

see below

Step-by-step explanation:

Consider the rule y = 5x + 7.

a. How many tiles are in Figure 0?

In figure 0, we let x=0

y = 5*0+7 = 0+7 = 7

b. Which figure has 37 tiles?

This means y = 37

37 = 5x+7

Subtract 7 from each side

37-7 = 5x+7-7

30 = 5x

Divide by 5

30/5 = 5x/5

6 =x

Figure 6 has 37 tiles

c. In the equation y = mx + b, what do the letters m and b represent?

m is the slope or how much it is increasing each time x increases by 1  and b is how much we start with when x =0

For f(x)=4x+1 and g(x) = x^2 - 5, find (f+g)(x).
Rus_ich [418]

Answer:

(f + g)(x) = x² + 4x - 4  

Step-by-step explanation:

The statement (f + g)(x) is the same as f(x) + g(x). In other words, the question simply wants you to add the two functions together.

f(x) = 4x + 1

g(x) = x² - 5

(f + g)(x)                                  <----- Original statement

f(x) + g(x)                                <----- Rewrite

(4x + 1) + (x² - 5)                     <----- Substitute the equations in f(x) and g(x)

4x + x² - 4                              <----- Add 1 and -5

x² + 4x - 4                              <----- Rearrange the terms
