1) move the 10 over
So it becomes
3/4b = 10
2) multiply everything by 4 to get rid of the denominator
2b = 40
3) divide both sides by 2
b = 20

\frac{3}{4}b+10=20 \ \ \ \ | - 10\\\\ \frac{3}{4}b=10 \ \ \ \ | \cdot4\\\\3b=40 \ \ \ \ | : 3\\\\b=\frac{40}{3}\\\\ b=13\frac{1}{3}

¡¡¡40 POINTS!!!HELP ASAP!!

Hi there!

To start, we can use the two points to find the slope using the formula y2-y1/x2-x1. Just sub in the points and solve!

-0.5-0.5/3-(-3)
-1/6
Sub that into the formula y-mx+b for m, and use one of the points for x and y - solve for b and you get your equation. 

y=mx+b
y=-1/6x+b
0.5=-1/6*-3+b
0.5=-0.5+b
0.5+0.5=b
b=1

Therefore your equation is y=-1/6x+1

Hope this helps!

Modulation is the process of a)Spinning a wheel to generate a sine wave b)Increasing the amplitude of a sine wave c)Changing one
hram777 [196]

Answer: C) Changing one or more properties of a sine wave in response to data.

Step-by-step explanation:

Modulation is primarily used in telecommunications sector. It the process by which data is transmitted via electrical signals. It is the process of imposing an input signal on to a wave carrier. It is the pillar of data communication that enables the use information carriers of signals that are electrical and optical. Altering the carrier/ periodic waveform results in Modulation. The amplitude frequency and phase are conveyed. There are different types of Modulation which includes: amplitude Modulation, frequency Modulation, and phase Modulation.

18x^2+21x-9 I need to figure out how to work this problem
shtirl [24]
18x^2+21x-9=3(6x^2)+3(7x)-3(3)\\\\=3(6x^2+7x-3)=3(6x^2+9x-2x-3)\\\\=3[3x(2x)+3x(3)-1(2x)-1(3)]\\\\=3[3x(2x+3)-1(2x+3)]\\\\=\boxed{3(2x+3)(3x-1)}

A late assignment is very much like a late payment on a credit card bill. If you lose 10 points for every day that an assignment is late and you have to pay a fee for however many days you forgot to pay the bill, (you are losing money for having to pay an extra fee). If you start the habits of turning in assignments in late.  Those habits will be carried with you into adulthood and you will owe a sum of money since you have failed to pay a bill on time. You will lose points for late work and you will lose money for late bills.
