Answer:
A=8,000,000
B=1,000,000
Step-by-step explanation:
A=8B
A+B=9,000,000
8B(because A=8B)+B=9,000,000
9B=9,000,000
B=1,000,000
A=8*B=8*1,000,000=8,000,000

Step-by-step explanation:
A number to the 9th power divided by the same number to the 6th power equals 125. What is the
number?
Answer:
5
Step-by-step explanation:
Let the required number be x
[tex] \huge {x}^{9} \div {x}^{6} = 125 \\ \\ \huge {x}^{9 - 6} = 125 \\ \\ \huge {x}^{3} = 125 \\ \\ \huge x = \sqrt[3]{125} \\ \\ \huge x = \sqrt[3]{ {5}^{3} } \\ \\ \huge \red{ x = 5}[/tex]

Answer:
[tex]=2x+h-2[/tex]
Step-by-step explanation:
When want to simplify:
[tex]\frac{f(x+h)-f(x)}{h}\text{ given } f(x)=x^2-2x[/tex]
So, let's substitute (x+h) into our f(x). This yields:
[tex]f(x+h)=(x+h)^2-2(x+h)[/tex]
Substitute this and f(x) into our above expression to obtain:
[tex]=\frac{(x+h)^2-2(x+h)-(x^2-2x)}{h}[/tex]
Simplify. First, square the first term:
[tex]=\frac{(x^2+2xh+h^2)-2(x+h)-(x^2-2x)}{h}[/tex]
Distribute the -2 for the second term:
[tex]=\frac{(x^2+2xh+h^2)-2x-2h-(x^2-2x)}{h}[/tex]
And distribute the negative for the last term:
[tex]=\frac{(x^2+2xh+h^2)-2x-2h-x^2+2x}{h}[/tex]
Combine like terms:
[tex]=\frac{(x^2-x^2)+(-2x+2x)+(2xh+h^2-2h)}{h}[/tex]
The first two expressions will cancel. This leaves us with:
[tex]=\frac{2xh+h^2-2h}{h}[/tex]
Factor out an h:
[tex]=\frac{h(2x+h-2)}{h}[/tex]
We can cancel the h. So, our final solution is:
[tex]=2x+h-2[/tex]
And we're done!

x=-2
y=-2
Step-by-step explanation:
Passes through the origin and has a slope of 2/3
Answer:
y = [tex]\frac{2}{3}[/tex] x
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( where m is the slope )
Here m = [tex]\frac{2}{3}[/tex] , thus
y = [tex]\frac{2}{3}[/tex] x ← equation of line

Let m AngleA = 40°. If AngleB is a complement of AngleA, and AngleC is a supplement of AngleB, find these measures
Answer:
mAngleB = 50 degrees
mAngleC = 130 degree
Step-by-step explanation:
The way I did this was by subtracting the given "mAngleA = 40" from the angle that complementary angles are at: 90 degrees, which means that equals 50 degrees. Then, I did the same with mAngleC with the angle that supplementary angles are at: 180 degrees. 180 - 50 = 130 degrees.
Hope my explanation wasn't too hard to follow!

Which line is parallel to the line 8x + 2y = 12?
Answer
its C, i just answered it
Can someone please help, ty!!
Answer:
-6
Step-by-step explanation:
We can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 8-2)/(3-4)
= 6/-1
= -6
Answer:
[tex] - 6[/tex]
Step-by-step explanation:
[tex]slope \: = \frac{y1 - y2}{x1 - x2} \\ = \frac{2 - 8}{4 - 3} \\ = \frac{ - 6}{1} \\ = - 6[/tex]
Can someone determine the values of AC AND CB please

Is this a linear function?
Answer:
No
Step-by-step explanation:
No
Because a linear function is the form as
[tex]f(x)=ax+b[/tex]
the highest exponent is one
and the graph is a line in the case of
[tex]p(x)=3x^2-4[/tex]
is a parabola, not a line
