Mathematics

dusya [7]3 years ago
6 0

Answer: No solution

Step-by-step explanation:

(10–3)–2=10–(3–)

10−3−2=10−3, this is false so it is not correct, and the answer for the equation is no solution.

If x/3= x+1/4, What is the value of x
olya-2409 [2.1K]
Well first because in this equation the first value is less than one, we should multiply the whole equation by 3, so
<span>x/3= x+1/4
x=3x+3/4
now we should switch the values
3x+3/4=x
now subtract x from both sides
2x+3/4=0
now subtract 3/4 from both sides
2x=-3/4
now divide both sides by 2
x=3/8
So that's your answer!

How is the distributive property used to expand expressions? provide an example
Pepsi [2]
Yes the distributive property is used to expand expressions, but it is also used to make it simpler.
For an example

3(x+4) + 3(y-8)
This is the same thing as
3x + 12 + 3y -8

Please help!
Aloiza [94]

Answer:

4 \sin( \frac{2}{7}x )  + 1

Step-by-step explanation:

Let use the basic function of sin first.

Since the midline is 1 and the max point is 5, the amplitude is 4.

The midline is 1 since the midline is at 0,1.

Since we know the distance of the max and midline x values

We can multiply that by 4 to find our period.

\frac{7\pi}{4}    \times 4 = 7\pi

Use the equation 2pi/b to find the b we would use in our equation.

\frac{2\pi}{b}  = 7\pi

The answer is

\frac{2}{7}

so our equation is

4 \sin( \frac{2}{7}x )   + 1

Solve the equation a = m – n for the variable n.
MaRussiya [10]

Answer:

m - a = n

Step-by-step explanation:

<u>Step 1:  Subtract m from both sides </u>

a - m = m - n - m

a - m = -n

<u>Step 2:  Divide both sides by -1 </u>

(a - m) / -1 = -n / -1

-a + m = n

m - a = n

Answer:  m - a = n
