Answer:

Yes it describes y as a function of x because the formula that is shown about show's y equaling numbers and symbols with only x.

Y as a function of x means y=some wierd formula with only x and numbers in it

y=-3x²-7x-6
yep, wierd formula, check. numbers, check. only x, check

also, if we graph it, there are no vertical ines we can draw that intersect the graph 2 times
basically every x maps to only 1 y

How many 4-digit number are divisible by 7,8,10 and 25

saw5 [17]

9514 1404 393

Answer:

Step-by-step explanation:

In order for a number to be divisible by all of 7, 8, 10, and 25, it must be a multiple of the least common multiple of those numbers.

LCM(7, 8, 10, 25) = 7×8×25 = 1400

There are floor(10,000/1,400) = 7 4-digit numbers divisible by 7, 8, 10, and 25. They are ...

1400, 2800, 4200, 5600, 7000, 8400, 9800

If Paul runs 5 miles in 3 hours, how many miles does he run in 24 hours?

BARSIC [14]

Answer -
40 miles

explanation -
it would be 40 miles because 3 x 8 = 24 hrs.
and then you would have to multiply 5 x 8 = 40 miles.

have a good day! :)

Suppose Tommy walks from his home at (0, 0) to the mall at (0, 7), and then walks to a movie theater at (5, 7). After leaving th

BaLLatris [955]

For this case, what we must do is find the distance between each ordered pair.
For this, we use the formula of distance between points.
We have then:
$d = \sqrt{(x2-x1)^2+(y2-y1)^2}$

For (0, 0) and (0, 7):
$d1=\sqrt{(0-0)^2+(7-0)^2}$
$d1=\sqrt{(0)^2+(7)^2}$
$d1=\sqrt{0+49}$
$d1=\sqrt{49}$
$d1=7$

For (0, 7) and (5, 7):
$d2=\sqrt{(5-0)^2+(7-7)^2}$
$d2=\sqrt{(5)^2+(0)^2}$
$d2=\sqrt{25+0}$
$d2=\sqrt{25}$
$d2=5$

For (5, 7) and (5, 0):
$d3=\sqrt{(5-5)^2+(7-0)^2}$
$d3=\sqrt{(0)^2+(7)^2}$
$d3=\sqrt{0+49}$
$d3=\sqrt{49}$
$d3=7$

before returning home the total distance is:
$d1 + d2 + d3 = 7 + 5 + 7

d1 + d2 + d3 = 19$

Answer:
before returning home Tommy walks about 19 blocks

Which restaurant has the greater rate of change?<br><br> A) Juice Jammers<br> B) Bob's Burgers

hodyreva [135]

Answer:

The answer is Juice Jammers

Step-by-step explanation:

To determine which has a greater rate of change calculate out the rate of change for Juice Jammers. In order to do so, we use the first two points in the table and the slope equation.

m(slope) = (y2 - y1)/(x2 - x1)

m = (29.25 - 0)/(25 - 0)

m = 29.25/25

m = 1.17

This gives Juice Jammers a higher rate of change than Bob's Burgers
