Answer:
The total population of these two states is:
![3.804\times \:\:10^7+2.606\times \:\:10^7\:=10^7\times \:\:6.41](https://tex.z-dn.net/?f=3.804%5Ctimes%20%5C%3A%5C%3A10%5E7%2B2.606%5Ctimes%20%5C%3A%5C%3A10%5E7%5C%3A%3D10%5E7%5Ctimes%20%5C%3A%5C%3A6.41)
Therefore, option C is correct.
Step-by-step explanation:
- The population of California is approximately 38,040,000.
- The population of Texas is about 2.606 × 10⁷.
Writing the population of California i.e.38,040,000 in scientific notation by moving the decimal point 7 places to the left and dropping the 0's on the right side as they're after the decimal point now.
i.e.
38,040,000 = 3.804 x 10⁷
So adding 3.804 x 10⁷ and 2.606 × 10⁷
i.e.
![3.804\times \:10^7+2.606\times \:10^7](https://tex.z-dn.net/?f=3.804%5Ctimes%20%5C%3A10%5E7%2B2.606%5Ctimes%20%5C%3A10%5E7)
![\mathrm{Add\:similar\:elements:}\:10^7\times \:3.804+10^7\times \:2.606=10^7\times \:6.41](https://tex.z-dn.net/?f=%5Cmathrm%7BAdd%5C%3Asimilar%5C%3Aelements%3A%7D%5C%3A10%5E7%5Ctimes%20%5C%3A3.804%2B10%5E7%5Ctimes%20%5C%3A2.606%3D10%5E7%5Ctimes%20%5C%3A6.41)
Thus, the total population of these two states is:
![3.804\times \:\:10^7+2.606\times \:\:10^7\:=10^7\times \:\:6.41](https://tex.z-dn.net/?f=3.804%5Ctimes%20%5C%3A%5C%3A10%5E7%2B2.606%5Ctimes%20%5C%3A%5C%3A10%5E7%5C%3A%3D10%5E7%5Ctimes%20%5C%3A%5C%3A6.41)
Therefore, option C is correct.
Answer:
X=4
Step-by-step explanation:
5x-4=16
+4 +4 Add 4 on both sides
5x=20 Divide both sides by 5
x= 4
Hope this helps!
Slope = (-2 + 4)/(-2-2) = 2/-4 = -1/2
y = mx + b
so
b = y - mx
b = -2 -(-1/2)(-2)
b = -2 - 1
b = - 3
equation
y = -1/2x - 3
answer is B.
y = -1/2x - 3
