Answer is D. 3(x - 7) = 3x - 21
because
3(x - 7) = 3x - 21
Distributive property
3x - 21 = 3x - 21
0 = 0
Infinitely many real solutions
5x-39.2
You get this answer my combining like terms
Answer:
37.22
Step-by-step explanation:
Let's use the point-slope formula...
<em>y-y1=m(x-x1)
</em>
<em>m is the slope.
</em>
<em>y--9=7(x--2)
</em>
<em>Subtracting a negative number is the same as adding a positive number...
</em>
<em>y+9=7(x+2)
</em>
<em>y+9=7x+14
</em>
<em>Let's subtract 9 from both sides...
</em>
<em>-9+y+9=7x+14-9
</em>
<em>y=7x+5
</em>
<em>The formula is now in the format of...
</em>
<em>y=mx+b
</em>
<em>This is known as slope-intercept.
</em>
<em>m is the slope.
</em>
<em>b is the y-intercept, the value of y when x=0.
</em>
<em>Standard formula is...
</em>
<em>Ax+By=C
</em>
<em>Neither A nor B equal zero.
</em>
<em>A is greater than zero.
</em>
<em>y=7x+5
</em>
<em>Let's move 7x to the left side of the equation. It becomes negative.
</em>
<em>-7x+y=5
</em>
<em>Let's multiply both sides by -1 to render A greater than zero.
</em>
<em>-1(-7x+y)=(5)(-1)
</em>
<u>7x-y=-5
</u>
<u>This is the equation in standard form.</u>
I will say the answer is 125
Each of them has a power of thirds
So it goes like this:
1 to the power 3 = 1
2 to the power 3 = 8
3 to the power 3 = 27
4 to the power 3 = 64
5 to the power 3 = 125
And I think this is one of the IQ test questions..haha
Hope this helped you =)
