<em>Answer:</em>
<em>we have
</em>
<em>
256^{\frac{3}{4}}
</em>
<em>
we know that
</em>
<em>
256=2^{8}
</em>
<em>
substitute
</em>
<em>
256^{\frac{3}{4}}=(2^{8})^{\frac{3}{4}}=2^{\frac{24}{4}}=2^{6}=64
</em>
<em>
therefore
</em>
<em>
the answer is the option
</em>
<em>
64</em>
<em>this is what i found </em>
So first we want to distribute. (#1)
So, using the distributive property, we can:
5 * 3x - 2y * 5 + 2x + 2 * 2y - 3 * 3x - 3 * 2y
or
15x - 10y + 2x + 4y - 9x - 6y
Now just combine like terms
8x -12y
So for #1 it should be a.
#2: 2x - 3 + 3x - 5
Combine Like Terms:
2x + 3x - 3 - 5
5x - 8
So it should be b.
Answer:
1/7, 2, 0.62, 40000000002342, 13, 23/478
Step-by-step explanation:
A number is rational if we can write it as a fraction, where both denominator and numerator are integers and denominator is a non-zero number.
Answer is B y = 2x - 17
First find the negative reciprocal of the gradient for y = -1/2 x + 1 to find the perpendicular line gradient.
-1/2 = 2
Gradient of perpendicular line = 2
Perpendicular line is y=2x + c
Substitute (8,-1) into the line to find the y-intercept (c).
-1 = 2(8) + c
-1 = 16 + c
c = -17
Therefore, the perpendicular line is y = 2x - 17.
