A number is 4 times another number. Their sum is 30.​

Mathematics
1 answer:
Gnom [1K]3 years ago
7 0

Answer:

24 and 6 are the 2 numbers

Step-by-step explanation:

let the 2 numbers be x and y , then

x + y = 30 → (1)

y = 4x → (2) [ one number is 4 times the other ]

Substitute y = 4x into (1)

x + 4x = 30

5x = 30 ( divide both sides by 5 )

x = 6

Substitute x = 6 into (2)

y = 4 × 6 = 24

The 2 numbers are 24 and 6

Find x. Assume that segments that appear tangent are tangent.
kipiarov [429]
Assuming that CB is tangent, this is just a right triangle with a hypotenuse of 20 and a side of 12 so by the Pythagorean Theorem:

20^2=12^2+x^2

400=144+x^2

x^2=400-144

x^2=256

x=16

What are the domain and range of the exponential function below? <br><br> <img src="https://tex.z-dn.net/?f=F%28x%29%20%3D%205%5
faust18 [17]

Answer:

B

Step-by-step explanation:

The domain is the set of x values for which the function is defined.

The range is the set of y values for which the function is defined.

Attached is the graph of the exponential function.

It is the basic graph of exponential function of y = 5^x which is shifted 6 units above (because of +6 at the end).

<em><u>Looking at the graph, the domain is the set of all x values.</u></em>

<em><u>The range is anything above 6.</u></em>

Correct answer is B.
