What is the answer to this equation:5x-4x+2=1

Mathematics
1 answer:
Paladinen [302]3 years ago
4 0

Answer:

x=-1

Step-by-step explanation:

5x-4x+2=1

Step 1: Simplify both sides of the equation.

5x-4x+2=1

5x+-4x+2=1

(5x+-4x)+(2)=1 (Combine Like Terms)

x+2=1

x+2=1

Step 2: Subtract 2 from both sides.

x+2-2=1-2

x=-1

Therefore, x=-1 will be your final answer.

Which expression is equivalent to n2 + 26n + 88 for all values of n?
Lelechka [254]

Answer:

Option B is correct.

The expression which is equivalent to  n^2+26n+88  is; (n+22)(n+4)

Explanation:

Given the equation: n^2+26n+88 for all values of n.

The quadratic equation in this form; ax^2+bx+c =0

First find two numbers that multiply to give ac and add to give b.

From the given equation;

a =1 , b = 26 and c =88

then,

the two number that multiply to give ac =88 is, 22 or 4

and they add up to give b=26 (i.e 22+4)

Now, rewrite the middle term i.e 26n with 22n and 4n , we have

n^2+22n+4n+88=0

Now, factor the first two terms and last two terms,

n(n+22)+4(n+22)

we see that (n+22) is common to both terms so, we have;

(n+22)(n+4)

Therefore, the expression (n+22)(n+4) is equivalent to  n^2+26n+88

Check:

(n+4)(n+22) = n\cdot n+ 22n+4n+88=n^2+26n+88   [ True]

Given that the function g is defined by the rule g(x)=3-2x,determine the following
Illusion [34]

Answer:

The value of g(a) is:

  • g(a) = 3 - 2a

Step-by-step explanation:

Given

As the function g(x) is given by

g(x)=3-2x

To determine

g(a) = ?

In order to determine g(a),

substitute x = a in the function g(x) = 3 - 2x

g(x) = 3 - 2x

g(a) = 3 - 2(a)

g(a) = 3 - 2a

Therefore, the value of g(a) is:

  • g(a) = 3 - 2a
