I NEED HELP FAST PLEASE !!!!!!!!!!! The grade of a hill steepness represented as a percent. Jim tracks his walking speed up different hills. What does the rate of change , or slope , represents in this situation a= the rate represents an increases in speed for each 1% b= the rate represents a decrease in speed for 1% grade c = the rate represents a decrease in speed for each 1% grade increase D= the rate represents no change in speed for each 1% grade decrease

I believe it's x= 20, hopes it help!

Answer:

x=20

Step-by-step explanation:

4 5 x

( 3 ) = 3

20 x

3 = 3

x = 20

Answer:

Points are ( 1, -2) , (-5, -2)

Step-by-step explanation:

the given point is A ( -2, -2)

If we fix the y coordinate , then we can change only x coordinate

As we want point 3 unit away

So, add 3 and subtract 3 from x coordinate to find the resultant point

If we add 3 to x coordinate , we get

-2 + 3 = 1

So the point be ( 1, -2)

If we subtract 3 to x coordinate , we get

-2 - 3 = -5

So the point be ( -5, -2)

Answer:

$1900.80

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 9.9%/100 = 0.099 per year,

then, solving our equation

I = 4800 × 0.099 × 4 = 1900.8

I = $ 1,900.80

The simple interest accumulated

on a principal of $ 4,800.00

at a rate of 9.9% per year

for 4 years is $ 1,900.80.

Answer:

-125

Step-by-step explanation:

sea level is zero so cant be above that and the answer has to be below -100 and the only option is -125

Answer:

A -125

Step-by-step explanation:

because they went over 100ft below sea level

and if sea level is exactly 0 and they went under it over 100 the only option over 100 with a negative sign to show they went below sea level would be -125

Answer:

y = 16

x = 2

Step-by-step explanation:

y = 8x

y = 4x + 8

then, by substitution:

8x = 4x + 8

8x - 4x = 8

4x = 8

x = 8/4

x = 2

y = 8x

y = 8*2

y = 16

Check:

y = 4x + 8

y = 4*2 + 8

16 = 8 + 8

Answer:

You would have to sell 10,000 in a week for the straight commission offer to be at least as good.

Step-by-step explanation:

From the information provided, you can find how much you would have to sell in a week in order for the straight commission offer to be at least as good by establishing an equation in which the amount earned in the first company is equal to the amount earned in the second company:

0.08x=500+0.03x, where x is the amount of sales

Now, you can solve for x:

0.08x-0.03x=500

0.05x=500

x=500/0.05

x=10,000

According to this, the answer is that you would have to sell 10,000 in a week for the straight commission offer to be at least as good.

The expression that is equivalent to 27x² - 72x/9x is 3x - 8

The expression whose equivalence is to be determined is given as

27x^2-72x/9x

The above expression can be properly expressed as follows

27x² - 72x/9x

Introduce the use of brackets

So, we have

(27x² - 72x)/9x

Factor out x from the numerator

This gives

(27x² - 72x)/9x = x(27x - 72)/9x

Cancel out the common factor

(27x² - 72x)/9x = (27x - 72)/9

Factor out 9 from the numerator

This gives

(27x² - 72x)/9x = 9(3x - 8)/9

Cancel out the common factor

(27x² - 72x)/9x = 3x - 8

Hence, the equivalent expression is 3x - 8

Responder:

Si el factor de escala de una figura es mayor que uno, la figura es mayor.

Explicación paso a paso:

Hará que la figura sea más grande porque si es menor que uno, la figura será menor. Por ejemplo, si el factor de escala es la mitad de la cifra, será la mitad más pequeña que la cifra original. Y si el factor de escala es 2, la figura será dos veces más grande que la figura original.

Answer:

(4,2)

Step-by-step explanation:

I am not able to see your screen well but these are the points that I saw in the beginning for E. 8,4. Your x value is either left or right and your y value is up and down. I saw 8 units right and 4 u it's up. Now your scale factor is 1/2. Remember if the scale factor is less than one the figure reduces. Our rule for dilations is (x,y) → (kx,ky). The scale factor is represented by K. Since your scale factor is 1/2 we know our triangle will reduce. Let's plug 1/2 in our x and y valued.

So E is (8,4). 8*1/2 is 4 and 4* 1/2 is 2. Are new points are E' (4,2).

Answer:

[tex]N=40[/tex]

Step-by-step explanation:

1) Remove parentheses.

[tex]\frac{n}{10} +6=10[/tex]

2) Subtract 6 from both sides.

[tex]\frac{n}{10} = 10-6[/tex]

3) Simplify 10-6 to 4.

[tex]\frac{n}{10} = 4[/tex]

4) Multiply both sides by 10.

[tex]n=4 times 10[/tex]

5) Simplify 4 times 10 to 40.

[tex]x=40[/tex]

Therefor, the answer is x=40.

Answer:

N = 40

n / 10 + 6 = 10

n / 10 - 6 = - 6

n / 10 = 4

n x 10 = 4 x 10

n = 40

Check answer: (40/10) + 6 = 10
