Answer:

Step-by-step explanation:

y=2x

if (2,6) lies on it ,then

6=3*2

or6=6

which is true .

hence (2,6) lies on the graph.

Write an inequality to match each description. Use n for the variable.

mel-nik [20]

${\huge {\mathfrak {Answer :-}}}$

Let, the length be l and breadth be b.

So, 2(l + b) = 26

Or, l + b = 13

Or, l = 13 - b

So, we may write like this,

Area = l * b

Or, l * b > 30

Or, l (13 - l) > 30

Or, 13l - l^2 > 30

Or, l^2 - 13l + 30 > 0

Or, l^2 - 3l - 10l + 30 > 0

Or, l(l - 3) - 10(l - 3) > 0

Or, (l - 3)(l - 7) > 0

Or, l - 7 > 0

Or, l > 7.

Now, putting the value of l,

We get, l * b > 30

Or, 7 * b > 30

Or, b > 30/7

➡️ Therefore, we get,

Length > 7

Breadth > 30/7

That's it..

Replace f(x) with 0 and swith the equation around to solve for x

x^4 - 32x^2 - 144 = 0

Factor the left side:

(x+6) (x-6) (x^2+4)

so far we have x+6 = 0, x = -6
x -6 = 0, x = 6

solve x^2 +4 = 0
x^2 = -4
x = sqrt(-4)
x = 2i, -21

The answer is B) 2i, 6, -6

You have been saving $12 each week for many weeks. One day, you decide to count your savings and find that you have $384. Choose

Answer:

D or the last one.

Step-by-step explanation:

Honestly, you got me kinda confused. Is it saying that there is multiple equations to answer this? Well anyways, D would be the answer. When the variable (w) is beside the coefficient, it means you multiple them together. (W) standing for weeks multiplied by 12 which is how much you earn each week would get you the total amount. The rest just don't make sense.

How far, D, does a vehicle travel if it is moving at a rate, r, of 60 km/h and it travels for t =150 minutes? Use the formula D=

strojnjashka [21]

The distance of a vehicle travel is 150 km, at a moving rate of 60 km/h for 150 minutes.

Step-by-step explanation:

The given is,

Moving rate, r = 60 km/h

Time, t = 150 minutes

Step:1

We need to find the distance traveled by the vehicle,

From given the formula is

D = rt

Where,

D = Distance in Km

r = Moving rate in Km/h

t = Time in hours

Step:2

We need to convert the time minutes to hours

t = $\frac{150}{60}$ hours

t = 2.5 hours

Step:3

Distance traveled by the vehicle is,

D = 60 × 2.5

= 150

D = 150 Km

Result:

The distance traveled by the vehicle is 150 Km at a moving rate of 60 km/h for 150 minutes.
