Mathematics
1 answer:
Colt1911 [192]3 years ago
8 0

Answer:

No

Step-by-step explanation:

Given

f(x) = \sqrt{x-10} + 11 ← substitute x = 1

f(1) = \sqrt{1-10} + 11

     = \sqrt{-9} + 11

\sqrt{-9}  is not real and therefore x = 1 does not have a real output for f(x)

Find the value of x in the equation below.<br> 48 = 6x
Akimi4 [234]

Answer:

x=8

Step-by-step explanation:

This is a simple one-step algebraic equation. In algebra, to find x you must isolate the variable. To do this, use the property of equality. This property states that an equation is still true if you do the same thing to both sides. For example, the equation would still be true if you added 1 to both sides.

To isolate x divide both sides by 6. This equals 48/6 = 6x/6. Which simplifies to 8=x.

Christine buys 7 hamburgers and 3 sodas for $27.95. Laura buys 5 hamburgers and 4 sodas for $23.40. How much does a hamburger co
Naddika [18.5K]
7h+3s=27.95 subtract 7h from both sides

3s=27.95-7h  divide both sides by 3

s=(27.95-7h)/3

Then we are told:

5h+4s=23.4,  using s found above makes this equation become:

5h+4(27.95-7h)/3=23.4  multiply both sides by 3

15h+4(27.95-7h=70.2  perform indicated multiplication on left side

15h+111.8-28h=70.2 combine like terms on left side

-13h+111.8=70.2 subtract 111.8 from both sides

-13h=-41.6  divide both sides by -13

h=$3.20
