Answer:

1. The y values are decreasing by 16 7 and 4 then rising by 7 and 16 so the line of symmetry is at -4 or 4

2. f = g(x) function just like g = f(x) function so say f value table or g(x) function

3. y = g(x) = -4 when x = 0

4. y - 0 = - 4x means the same as y = -4x

5. [0 , -4] is the vertex

6. 6(5) = 30

which means thy are increasing minimum by 1/1.5 and could be a square function.

8. This is a g function or a f(x).

9. y intercept is 1

10 common ratio is 0:1

11 equation for the table is y = x -1

12. 5.400

The values for y are decreasing by 2 then drop by 12 from -2/14 to 0/-2 then increase again at a rate of 20 and decrease slightly to 18 being -2/-20

we can see this as -2/16 ,-2/14 , 0/-2 2/ -22 meaning the line of symmetry is not clear as we cannot see an average without working out the mean or adding all the totals up.

14. p(x) function or q value.

15. the y intercept is -2

16. the equation for this table is y = x-2

17.

The value for p(4) is same method divide smaller into larger then times x 4

-20/-2 = 10

then -11 x 10 = -110

18. slope = -2

17) if they were asking for value for 4(p) is 16/ -2 = 8 and -2 / 4 = 0.5/ 8 this shows 8 so 4 is half this value = 0.24 / 4 meaning x = 0.24

Answer:

$45

Step-by-step explanation:

1.54(x) = 69.3

Divide both sides by 1.54

x = 45

Anty was riding his bike to school at a speed of 12 mph. When he was of the way there, he got a flat tire. His mother drove him

NemiM [27]

Complete question:

Anty was riding his bike to school at a speed of 12 mph. When he was <u>half </u>of the way there, he got a flat tire. His mother drove him the rest of the way at a speed of 48 mph. What was his average speed?

Answer:

His average speed is 19.2 mph

Step-by-step explanation:

Given;

speed of Anty to school half of the way, v₁ = 12 mph

speed of Anty when his mother drove him half of the way, v₂ = 48 mph

The average speed of Anty is calculated as;

$V_{average} = \frac{Total \ distance }{Total \ time }$

The value of the average speed is closer to 12 mph than 48 mph because Anty spent more time moving at 12 mph than at 48 mph.

Let the equal distance travel at each speed = 96 miles

Time taken at 12 mph = $\frac{96 \ mile}{12 \ m/h} = 8 \ hours$

Time taken at 12 mph = $\frac{96 \ mile}{48 \ m/h} = 2 \ hours$

Average speed = $\frac{Total \ distance}{Total \ time } = \frac{96 \ mile \ + \ 96 \ mile}{2\ hr \ + \ 8\ hr} = \frac{192 \ miles}{10 \ hrs} = 19.2 \ mph$
