(a) Without solving the equation we can't determine whether its true or false.
(b) If x = 3
4x + 1 = 2x + 5
4(3) + 1 = 2(3) + 5
12 + 1 = 15 + 5
13 = 20
No, if x = 3, the equation will not be true.
(c) 4x + 1 = 2x + 5
4x - 2x = 5 - 1
2x = 4
x = 4/2
x = 2
This shows that x = 2 makes the equation true.
Answer:
0.25
Step-by-step explanation:
<u>Fractions and decimals are not integers.</u> Any and all whole numbers, 1, 2,3, 4, -1, -2, -3, -4 etc. are integers. 0.25 is a decimal and therefore not an integer.
<u>Hope this helps and have a nice day!</u>
Answer:14
Step-by-step explanation:
Answer:
$57.50
Step-by-step explanation:
- 75(0.2 discount)
- =15
- 75-15
- =50
- 50(0.15 sales tax)
- =7.50
- 50+7.50
- =57.50
Can you mark me brainliest on both of my answers pleaseee. I would appreciate it (✿◠‿◠)
We have been given an equation of hyperbola
. We are asked to find the center of hyperbola.
We know that standard equation of a vertical hyperbola is in form
, where point (h,k) represents center of hyperbola.
Upon comparing our given equation with standard vertical hyperbola, we can see that the value of h is 6.
To find the value of k, we need to rewrite our equation as:

Now we can see that value of k is
. Therefore, the vertex of given hyperbola will be at point
and option D is the correct choice.
