4
5
6
7

Answers

Answer 1

Answer:

The value of y in the given equation is 7.

The given equation is:

2(2y -14)= 0

Bydividing 2 from both the sides, we get:

⇒2y -14= 0

Adding 14 on both the sides, we get;

2y =14

On dividing 2 from both sides, we get;

y=7

Hence, the value of y is 7.

What value of x will make 2x-6=3x+1-x-7 true?

Answers

2x-6=3x=3x+1-x-7
2x-6=(3-1)x+7
2x-6=2x+8
2x-6-2x+6=2x-2x+8+6
0=0+14
No Solution

Hi there

2x - 6 = 3x + 1 - x - 7
First we need to combine like terms
2x - 6 = (3x - x) + (1 - 7)
2x - 6 = 2x - 6
2x - 2x = -6 + 6
0 = 0
Answer : All real numbers are solutions.

How to find the equation of a hyperbola when given the vertices and foci

Answers

Step-by-step explanation:

The vertices and foci are on the x-axis. Thus, the equation for the hyperbola will have the form x2a2−y2b2=1 x 2 a 2 − y 2 b 2 = 1 . The vertices are (±6,0) ( ± 6 , 0 ) , so a=6 a = 6 and a2=36 a 2 = 36 . The foci are (±2√10,0) ( ± 2 10 , 0 ) , so c=2√10 c = 2 10 and c2=40 c 2 = 40 .

David typed 210 words in 30 minutes. What is her rate of typing?

Answers

210 words ... 30 minutes
x words ... 1 minute

If you would like to know how many words can David type in 1 minute, you can calculate this using the following steps:

x * 30 = 210 * 1 /30
x = 210 / 30
x = 7 words

Result: David can type 7 words in 1 minute.
